Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
In the video network, data transmitted between two video network terminals are forwarded through a video network server. The embodiment of the invention is provided with the multi-channel transcoder, which is respectively in communication connection with the video networking server and the plurality of video networking terminals and is used for judging whether transcoding is needed or not according to the video data packets transmitted between the video networking terminals and the video networking servers and carrying out transcoding operation when transcoding is needed. Therefore, the video network terminal does not need to be upgraded, the processing process is simplified, and the cost is reduced. The video network terminal can be a set-top box, a protocol gateway, a streaming media gateway, and the like.
Hereinafter, a video transcoding method in the embodiment of the present invention is described in detail.
Example one
Referring to fig. 1, a flowchart illustrating steps of a video transcoding method according to a first embodiment of the present invention is shown. The video transcoding method provided by the embodiment of the invention can be applied to a multi-channel transcoder.
The video transcoding method of the embodiment of the invention can comprise the following steps:
And the video data packet can be packaged with information such as coding and decoding information corresponding to the video data packet and the identification of the target video network terminal. After the multi-channel transcoder acquires the video data packet sent by the first device, the multi-channel transcoder analyzes the video data packet to obtain the coding and decoding information corresponding to the video data packet and the identification of the target video networking terminal. In the embodiment of the present invention, the coding and decoding information corresponding to the video data packet sent by the first device is referred to as first coding and decoding information.
And 102, acquiring second coding and decoding information supported by the target video network terminal according to the identifier of the target video network terminal.
The multi-channel transcoder can pre-store the corresponding relation between the identification of each video network terminal and the supported coding and decoding information. And the multi-channel transcoder can acquire the coding and decoding information supported by the target video network terminal by inquiring the corresponding relation according to the identifier of the target video network terminal obtained by analysis. In the embodiment of the invention, the coding and decoding information supported by the target video network terminal is called as second coding and decoding information.
And 103, when the first coding and decoding information and the second coding and decoding information are incompatible, transcoding the video data packet according to the second coding and decoding information.
And step 104, transmitting the transcoded video data packet to a second device.
And after obtaining the first coding and decoding information and the second coding and decoding information, the multi-channel transcoder determines whether the first coding and decoding information and the second coding and decoding information are compatible. The first codec information and the second codec information may be compatible with each other, and whether the first codec information and the second codec information are the same may be referred to as "whether the first codec information and the second codec information are the same.
And if the first coding and decoding information and the second coding and decoding information are incompatible, transcoding the video data packet according to the second coding and decoding information, and transmitting the transcoded video data packet to the second equipment. If the first coding and decoding information is compatible with the second coding and decoding information, the multi-channel transcoder does not transcode the video data packet, and data forwarding and transparent transmission are carried out on the video data packet, namely the multi-channel transcoder transmits the video data packet sent by the first equipment to the second equipment.
In practical application, when a source video network terminal sends a video data packet to a target video network terminal, the video data packet is forwarded through a video network server. If a multi-channel transcoder is connected between the source video network terminal and the video network server, the multi-channel transcoder processes a video data packet sent to the video network server by the source video network terminal. If a multi-channel transcoder is connected between the video networking server and the target video networking terminal, the multi-channel transcoder processes a video data packet sent to the target video networking terminal by the video networking server. Therefore, in the embodiment of the invention, the first device is a source video network terminal, and the second device is a video network server; or the first device is a video network server, and the second device is a target video network terminal.
For example, the source video network terminal and the target video network terminal are both connected with the multi-channel transcoder.
When the source video network terminal sends a video data packet to the video network server, the first device is the source video network terminal, and the second device is the video network server. And the multi-channel transcoder connected with the source video networking terminal acquires a video data packet sent by the source video networking terminal, and analyzes first coding and decoding information and the identifier of the target video networking terminal from the video data packet, wherein the first coding and decoding information is coding and decoding information adopted when the source video networking terminal codes. And acquiring second coding and decoding information supported by the target video network terminal according to the identifier of the target video network terminal. And when the first coding and decoding information and the second coding and decoding information are incompatible, transcoding the video data packet according to the second coding and decoding information, and transmitting the transcoded video data packet to the video networking server. And when the first coding and decoding information is compatible with the second coding and decoding information, transcoding is not carried out, and the video data packet sent by the source video network terminal is transmitted to the video network server.
When the video networking server sends a video data packet to the target video networking terminal, the first equipment is the video networking server, and the second equipment is the target video networking terminal. And the multi-channel transcoder connected with the target video network terminal acquires a video data packet sent by the video network server, and analyzes the first coding and decoding information and the identifier of the target video network terminal from the video data packet. If the multi-channel transcoder connected with the source video networking terminal transcodes the video data packet sent by the source video networking terminal, the first coding and decoding information is the coding and decoding information after the multi-channel transcoder connected with the source video networking terminal transcodes the video data packet; if the multi-channel transcoder connected with the source video network terminal does not transcode the video data packet sent by the source video network terminal, the first codec information is the codec information adopted by the source video network terminal during encoding. And acquiring second coding and decoding information supported by the target video network terminal according to the identifier of the target video network terminal. Because the multi-channel transcoder connected with the source video network terminal already performs the compatibility judgment and transcoding operation once, the multi-channel transcoder connected with the target video network terminal judges that the first coding and decoding information is compatible with the second coding and decoding information, and transmits the video data packet sent by the video network server to the target video network terminal without transcoding.
For example, the source video network terminal is connected with the multi-channel transcoder, and the target video network terminal is not connected with the multi-channel transcoder.
When the source video network terminal sends a video data packet to the video network server, the first device is the source video network terminal, and the second device is the video network server. And the multi-channel transcoder connected with the source video networking terminal acquires a video data packet sent by the source video networking terminal, and analyzes first coding and decoding information and the identifier of the target video networking terminal from the video data packet, wherein the first coding and decoding information is coding and decoding information adopted when the source video networking terminal codes. And acquiring second coding and decoding information supported by the target video network terminal according to the identifier of the target video network terminal. And when the first coding and decoding information and the second coding and decoding information are incompatible, transcoding the video data packet according to the second coding and decoding information, and transmitting the transcoded video data packet to the video networking server. And when the first coding and decoding information is compatible with the second coding and decoding information, transcoding is not carried out, and the video data packet sent by the source video network terminal is transmitted to the video network server. When the video networking server sends the video data packet to the target video networking terminal, the video networking server can directly forward the video data packet sent by the multi-channel transcoder connected with the source video networking terminal to the target video networking terminal because the target video networking terminal is not connected with the multi-channel transcoder.
For example, the source video network terminal is not connected with the multi-channel transcoder, and the target video network terminal is connected with the multi-channel transcoder.
When the source video network terminal sends the video data packet to the video network server, the source video network terminal can directly send the video data packet to the video network server because the source video network terminal is not connected with the multi-channel transcoder. When the video networking server sends a video data packet to the target video networking terminal, the first equipment is the video networking server, and the second equipment is the target video networking terminal. And the multi-channel transcoder connected with the target video network terminal acquires a video data packet sent by the video network server, and analyzes first coding and decoding information and the identifier of the target video network terminal from the video data packet, wherein the first coding and decoding information is coding and decoding information adopted when the source video network terminal codes. And acquiring second coding and decoding information supported by the target video network terminal according to the identifier of the target video network terminal. And when the first coding and decoding information and the second coding and decoding information are incompatible, transcoding the video data packet according to the second coding and decoding information, and transmitting the transcoded video data packet to a target video network terminal. And when the first coding and decoding information is compatible with the second coding and decoding information, transcoding is not carried out, and the video data packet sent by the video networking server is transmitted to the target video networking terminal.
In the embodiment of the invention, before the video data packet sent by the source video networking terminal is transmitted to the target video networking terminal, the multi-channel transcoder transcodes the video data packet according to the coding and decoding information of the target video networking terminal to obtain the video data packet which can be processed by the target video networking terminal and transmits the video data packet to the target video networking terminal. Therefore, the video networking terminal does not need to be upgraded, the multi-channel transcoder can cover various resolutions and coding formats, the video data packets of the multi-channel video networking terminal can be processed, the processing process is simpler and more convenient, and the cost is lower.
Example two
Referring to fig. 2, a flowchart illustrating steps of a video transcoding method according to a second embodiment of the present invention is shown.
The video transcoding method of the embodiment of the invention can comprise the following steps:
The first codec information includes a first encoding format and a first resolution, and the first resolution is a resolution at the time of encoding and decoding. The identifier of the target video network terminal may be information capable of uniquely identifying the video network terminal, such as a terminal number of the target video network terminal, a Media Access Control (MAC) address, and the like.
And second coding and decoding information.
The second encoding and decoding information comprises a second encoding format and a second resolution, and the second resolution is the resolution of the target video network terminal during encoding and decoding.
And 203, respectively acquiring the load information of each coding and decoding chip according to a preset time interval.
In the embodiment of the invention, the multi-channel transcoder comprises at least two coding and decoding chips, and the coding and decoding chips can be used for transcoding the video data packet.
The multi-channel transcoder can acquire the load information of each codec chip according to a preset time interval. The obtaining here may be actively obtained from each codec chip according to a preset time interval, or actively reported according to a preset time interval for each codec chip. The codec chip includes multiple codec resources, and the load information of the codec chip may refer to the number of paths of the codec resources occupied in the codec chip.
For the specific value of the preset time interval, a person skilled in the art may set any suitable value according to practical experience, and the embodiment of the present invention is not limited thereto.
After the first coding and decoding information and the second coding and decoding information are obtained, whether the first coding and decoding information and the second coding and decoding information are compatible or not is judged.
In the embodiment of the invention, the current coding and decoding chip is a coding and decoding chip which acquires the video data packet sent by the first device, and analyzes the video data packet to obtain the first coding and decoding information corresponding to the video data packet and the identifier of the target video network terminal.
When it is determined in step 204 that the first encoding and decoding information and the second encoding and decoding information are incompatible, the multi-channel transcoder determines whether the current encoding and decoding chip is in transcoding satisfaction with the video data packet according to the load information of the current encoding and decoding chip.
In the implementation, the number of encoding and decoding resources required for transcoding the video data packet is obtained. And determining the path number of idle coding and decoding resources in the current coding and decoding chip according to the load information of the current coding and decoding chip, namely the path number of the coding and decoding resources occupied in the current coding and decoding chip. Specifically, the total number of the encoding and decoding resources in the current encoding and decoding chip is calculated to subtract the number of the occupied encoding and decoding resources, and then the number of the idle encoding and decoding resources can be obtained. And judging whether the number of paths of the idle coding and decoding resources in the current coding and decoding chip is greater than or equal to the number of paths of the coding and decoding resources required for transcoding the video data packet. If so, determining that the current coding and decoding chip meets the requirement of transcoding the video data packet; if not, determining that the current coding and decoding chip does not meet the requirement of transcoding the video data packet.
And step 206, when the current coding and decoding chip does not meet the requirement of transcoding the video data packet, selecting a target coding and decoding chip meeting the requirement of transcoding the video data packet from other coding and decoding chips according to the load information of other coding and decoding chips.
In step 205, when it is determined that the current codec chip does not satisfy transcoding of the video data packet, the multi-channel transcoder may select a target codec chip that satisfies transcoding of the video data packet from other codec chips according to load information of the other codec chips.
In implementation, for each other codec chip, the number of paths of the idle codec resources in the other codec chip is determined according to the load information of the other codec chip, that is, the number of paths of the codec resources occupied in the other codec chip. And specifically, the total way number of the coding and decoding resources in the other coding and decoding chips is calculated to subtract the way number of the occupied coding and decoding resources, so that the way number of the idle coding and decoding resources can be obtained. And judging whether the number of paths of the idle coding and decoding resources in the other coding and decoding chips is greater than or equal to the number of paths of the coding and decoding resources required for transcoding the video data packet. If so, determining that the other coding and decoding chips meet the requirement of transcoding the video data packet; if not, determining that the other encoding and decoding chips do not meet the requirement of transcoding the video data packet.
And the multi-channel transcoder selects a target coding and decoding chip which meets the requirement of transcoding the video data packet from other coding and decoding chips. The selecting process may be selecting one connected to the current codec chip, selecting one randomly, or selecting one with the largest number of paths of idle codec resources.
And step 207, transcoding the video data packet by using the target coding and decoding chip according to the second coding and decoding information.
And after a target coding and decoding chip meeting the requirement of transcoding the video data packet is selected, transcoding the video data packet by using the target coding and decoding chip according to the second coding and decoding information.
And 208, when the current coding and decoding chip is used for transcoding the video data packet, transcoding the video data packet by using the current coding and decoding chip according to the second coding and decoding information.
In step 205, when it is determined that the current codec chip is in a condition of transcoding the video data packet, the current codec chip is used to transcode the video data packet according to the second codec information.
In this embodiment of the present invention, the first encoding/decoding information includes a first encoding format and a first resolution, and the second encoding/decoding information includes a second encoding format and a second resolution. For encoding formats, the multi-way transcoder may automatically transcode for an encoding format if the encoding formats are incompatible. Regarding the resolution, since the multi-way transcoder considers whether the resolutions at the time of encoding and decoding are compatible, but does not consider the resolution supported by the display of the target video network terminal at the time of displaying (since the display to which the target video network terminal can be connected is not fixed, it is difficult for the multi-way transcoder to know the resolution supported by the display of the target video network terminal in advance), if the multi-way transcoder transcodes the resolutions directly, it may cause the display of the target video network terminal to be abnormal.
Therefore, in the embodiment of the invention, the multi-channel transcoder is also in communication connection with the background management end, and the background management end can acquire the resolution supported by the display of the target video network terminal, so that whether transcoding is performed or not can be controlled by the background management end aiming at the resolution.
In the above step 207 and step 208, the process of transcoding the video data packet according to the second codec information may include steps a1 to A3:
step a1, converting the encoding format of the video data packet from the first encoding format to the second encoding format.
For the coding format of the video data packet, if the first coding format and the second coding format are not compatible, the multi-channel transcoder converts the coding format of the video data packet from the first coding format to the second coding format.
Step a2, transmitting the second resolution to the backend management end.
Step a3, receiving response information returned by the background management end for the second resolution, and transcoding the resolution of the video data packet according to the response information.
And after receiving the second resolution, the background management terminal inquires whether the display of the target video network terminal supports the second resolution. And if the display of the target video network terminal supports the second resolution, the target video network terminal returns information supporting the second resolution to the background management terminal, and the background management terminal returns a transcoding permission instruction to the multi-channel transcoder. And if the display of the target video network terminal does not support the second resolution, the target video network terminal returns information that the second resolution is not supported to the background management terminal, and the resolution supported by the display of the target video network terminal is returned to the background management terminal, and the background management terminal takes the resolution supported by the display of the target video network terminal as the target resolution and returns the target resolution to the multi-channel transcoder.
And the multi-channel transcoder receives response information returned by the background management end and transcodes the resolution of the video data packet according to the response information. The specific process can comprise the following steps A31-A34:
step a31, when the response information is a transcoding permission instruction, converting the resolution of the video data packet from the first resolution to the second resolution.
Step a32, when the response information is the target resolution, determining whether the response information supports the target resolution.
Step a33, when the target resolution is supported by itself, converting the resolution of the video data packet from the first resolution to the target resolution.
Step a34, when the target resolution is not supported by itself, keeping the resolution of the video data packet at the first resolution.
After receiving the target resolution returned by the background management end, the multi-channel transcoder determines whether the multi-channel transcoder supports the target resolution, namely whether the multi-channel transcoder can convert the first resolution into the target resolution. And when the multi-channel transcoder supports the target resolution, the multi-channel transcoder converts the resolution of the video data packet from the first resolution to the target resolution.

Fig. 5 is a structural diagram of an acquisition board according to a third embodiment of the present invention. As shown in fig. 5, the acquisition board includes an RJ-45 interface (1000Mb), two codec chips 3531D _ a and 3531D _ B, and a connector. The RJ-45 interface is used for connecting with a video network terminal, 3531D _ a and 3531D _ B are connected through a PCIE (peripheral component interconnect express) interface, and 3531D _ B is connected with a card slot of the data exchange board through a PHY (physical layer) interface and a connector. Moreover, each codec chip can be connected with an FPGA of the data exchange board through an IIC bus (not shown in the figure).
The video transcoding process of the embodiment of the invention can comprise the following steps:
1. when the video data packet is sent to the multi-channel transcoder from the source video networking terminal, 3531D _ A in the multi-channel transcoder receives the video data packet, analyzes the transmitted video data packet, and obtains first coding and decoding information corresponding to the video data packet and an identifier of the target video networking terminal. 3531D _ A transmits the first coding and decoding information and the identification of the target video network terminal to the FPGA through the IIC bus.
2. The multi-way transcoder can acquire the coding and decoding information supported by each video network terminal in real time, and store the information in a database (which can also be a memory in fig. 4) inside the multi-way transcoder. And after querying second coding and decoding information supported by the target video network terminal from the database according to the identifier of the target video network terminal, the FPGA judges whether transcoding operation is required.
3. If the transcoding operation is not needed, the FPGA informs 3531D _ A that transcoding is not needed, 3531D _ A transmits the video data packet to 3531D _ B through a PCIE interface, 3531D _ B transmits the video data packet to the FPGA, and the FPGA forwards the video data packet to a video network server through a ten-gigabit network interface.
4. And each coding and decoding chip reports the load information of the coding and decoding chip to the FPGA in real time through the IIC bus. If transcoding operation is needed, the FPGA judges whether 3531D _ A can meet the requirement of transcoding the video data packet. If 3531D _ A can be satisfied, the FPGA transmits the second coding and decoding information back to 3531D _ A, and the 3531D _ A transcodes the video data packet according to the second coding and decoding information. If 3531D _ A cannot be met, the FPGA selects 3531D _ B that can be met, transmits second codec information back to 3531D _ B, and notifies 3531D _ A to transmit video data packets to 3531D _ B. 3531D _ A transmits the video data packets to 3531D _ B through the PCIE interface, and 3531D _ B transcodes the video data packets according to the second coding and decoding information. Through the mode, the FPGA can flexibly schedule the coding and decoding chips, and related data are transmitted between the coding and decoding chips through the PCIE interface, so that automatic scheduling is realized, and transcoding efficiency is maximized. In transcoding video data packets, the transcoding operation involves two types: in the first category, the coding formats are incompatible, for example, H.264 or H.265 coding and decoding are not supported, and the scene coding and decoding chip automatically transcodes without manual confirmation. And in the second type, the resolution is incompatible, for example, 4K or 8K is not supported, in the scene, due to the fact that abnormal display may be caused, the encoding and decoding chip sends resolution correction information (including the resolution supported by the target video network terminal) to the background management terminal, and the background management terminal performs transcoding after confirming that no error exists.
5. If the 3531D _ A transcodes the video data packet, after the transcoding is completed, the 3531D _ A transmits the transcoded video data packet to the 3531D _ B through the PCIE interface, the 3531D _ B transmits the transcoded video data packet to the FPGA, and the FPGA forwards the transcoded video data packet to the video networking server through the gigabit network interface. If the 3531D _ B transcodes the video data packet, after the transcoding is finished, the 3531D _ B transmits the transcoded video data packet to the FPGA, and the FPGA forwards the transcoded video data packet to the video networking server through the ten-gigabit network port.
6. When the video data packet is sent from the video networking server to the multi-way transcoder, the FPGA of the multi-way transcoder receives the video data packet and transmits the video data packet to 3531D _ B. 3531D _ B analyzes the transmitted video data packet to obtain the first coding and decoding information corresponding to the video data packet and the identification of the target video network terminal. 3531D _ B transmits the first coding and decoding information and the identification of the target video network terminal to the FPGA through the IIC bus.
7. And after querying second coding and decoding information supported by the target video network terminal from the database according to the identifier of the target video network terminal, the FPGA judges whether transcoding operation is required.
8. If the transcoding operation is not needed, the FPGA informs 3531D _ B that transcoding is not needed, 3531D _ B transmits the video data packet to 3531D _ A through a PCIE interface, and 3531D _ A transmits the video data packet to a target video networking terminal.
9. If transcoding operation is needed, the FPGA judges whether 3531D _ B can meet the requirement of transcoding the video data packet. If 3531D _ B can be satisfied, the FPGA transmits the second coding and decoding information back to 3531D _ B, and the 3531D _ B transcodes the video data packet according to the second coding and decoding information. If 3531D _ B cannot, the FPGA selects 3531D _ A that can be satisfied, transmits the second codec information back to 3531D _ A, and notifies 3531D _ B to transmit the video data packet to 3531D _ A. 3531D _ B transmits the video data packets to 3531D _ A through the PCIE interface, and 3531D _ A transcodes the video data packets according to the second coding and decoding information. The transcoding method may refer to the description of process 4 above.
10. If the 3531D _ B transcodes the video data packet, after the transcoding is completed, the 3531D _ B transmits the transcoded video data packet to the 3531D _ A through the PCIE interface, and the 3531D _ A transmits the transcoded video data packet to the target video network terminal. If the 3531D _ A transcodes the video data packet, after the transcoding is finished, the 3531D _ A transmits the transcoded video data packet to a target video network terminal.
The following examples are given. Fig. 6 is a schematic flowchart of video transcoding according to a third embodiment of the present invention. As shown in fig. 6, the video transcoding process may include:
1. the terminal a sends a data packet M with an encoding format of h.265 and a resolution of 4K.
2. After the data packet M enters the acquisition board, the data packet M is received by 3531D _ A of the acquisition board, and the 3531D _ A sends the coding format and the resolution of the data packet M and the identification of the target terminal B to the FPGA through an IIC bus.
3. After acquiring the identifier of the target terminal B, the FPGA queries in a database to acquire the encoding format of the target terminal B as H.264 and the resolution as 1080P.
4. And the FPGA judges that transcoding is needed, and transmits the encoding format H.264 and the resolution 1080P of the target terminal B back to 3531D _ A through the IIC bus.
5. 3531D _ A starts decoding H.265 and sends a query whether the resolution is reduced to 1080P to a background management end, and the background management end selects according to the actual situation and controls whether the resolution is variable. If not, 3531D _ A replies to terminal A with a transcoding disabled operation. If the selection is yes, the resolution of 3531D _ A is reduced to 1080P, H.264 encoding is started, the encoded data are transmitted to 3531D _ B through a PCIE interface, and the 3531D _ B sends the data to a video network server through a data exchange board.
The process of sending the data packet to the target video network terminal B by the video network server is similar to the above, and the embodiment of the present invention is not discussed in detail herein.
The embodiment of the invention can realize the direct intercommunication of videos with different resolutions and different coding formats, simultaneously process the coding and decoding data in an intensive way and save the cost.
