Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The server-based material preview method provided by the invention can be applied to the application environment shown in figure 1, wherein a local playing end is in communication connection with a main server and a secondary server; the remote playing end is in communication connection with the secondary server, and the local playing end and the remote playing end can be understood as video software arranged in the server.
In one embodiment, as shown in fig. 2, a server-based material previewing method is provided, which is applied to a material playing system composed of a master server and at least one slave server in fig. 1, wherein the master server and the slave server are communicatively connected, and the method includes the following steps S10-S20:
s10, when at least one slave server receives a material preview instruction sent by the main server, playing a first original material at a far-end playing end corresponding to the slave server receiving the material preview instruction;
understandably, the first original material is a video material corresponding to a far-end playing end of the secondary server, and the low-code-stream material corresponding to the first original material is a video material corresponding to a local playing end of the primary server; the material preview instruction is an instruction (low-code-stream material preview mode) sent from a local playing end in the main server, and the low-code-stream material and the second original material corresponding to the first original material can be displayed on a display interface corresponding to the local playing end through the instruction, wherein the material can be displayed through a display window in the display interface, the size of the display window can be adaptively set according to the resolution of the video material, and the number of the display windows can be adaptively set according to the number of the video material; in this embodiment, when the secondary server receives the material preview instruction, the remote playing end can play the first original material, and the local playing end simultaneously plays the low-code-stream material corresponding to the first original material according to the method in step S20.
S20, the local playing end corresponding to the main server synchronously plays the low-code-stream material and the second original material corresponding to the first original material so as to realize synchronous material preview of the low-code-stream material and the second original material on the main server; the first raw material and the second raw material are derived from the same material or different materials.
Understandably, the second original material may be a video material composed of the first original material corresponding to each secondary server, a video material composed of the first original material corresponding to the secondary server (the video materials corresponding to all the secondary servers are completely the same), or a video material completely different from the secondary server; the method comprises the following steps that a communication connection relation exists between a main server and secondary servers, a local playing end of the main server bears the function of controlling all the secondary servers and the main server, namely when a video material playing instruction is issued to all the servers in the local playing end of the main server, display screens (including an LED display screen and a computer screen) connected with the main server and the secondary servers need to play corresponding video materials, the display screens corresponding to the main server play second original materials, and the display screens corresponding to all the secondary servers play first original materials; when a material preview instruction is issued to all servers in a local playing end of a main server (in addition, according to specific conditions, the invention can select a preset number of secondary servers from secondary servers playing video materials to issue the material preview instruction according to specific requirements), display screens connected with the main server and the secondary servers (all need to play corresponding video materials, including that a display screen corresponding to the main server plays a first original material, and a display screen corresponding to each secondary server plays a low-code stream corresponding to the first original material; it needs to be noted that the low-code stream material corresponding to the first original material can realize transcoding through a third-party transcoding platform and can also realize transcoding through the local playing end, wherein the main stream commonly used video formats can be suitable for transcoded formats such as MP4, AVI, PMP and the like, and the transcoding is also in a decoding and encoding mode, the coding is suitable for common mainstream coding modes, such as MPEG-4, MPEG-2, WMV-HD, H264 and the like; in addition, when the secondary server is a backup server of the main server, namely a server backup system is constructed by the main server and the secondary server, when the main server fails to work normally, the secondary server replaces the main server to continue working, but the secondary server and the main server process the same materials at the moment;
in this embodiment, when the local play end in the main server previews the material, the second original material corresponding to the main server is already finished being on the screen (LED screen), that is, the second original material is already decoded and encoded in the local play end, so that the material previewed by the local play end in the main server is the second original material, the performance of the main server is not reduced due to decoding and encoding, and decoding and encoding of the first original material corresponding to each sub-server are implemented by each sub-server, so that the material previewed by the local play end in the main server is the low-code-stream material corresponding to the first original material, and the low-code-stream material is decoded and encoded;
in another embodiment, the local play end of the main server may also preview any one of the low-stream material and the second raw material.
In the embodiments of steps S10 to S20, when playing the material, the high-resolution first original material corresponding to the plurality of sub servers is mainly converted into the low-code-stream material, and then the low-code-stream material and the second original material corresponding to the main server are synchronously played through the local playing end of the main server, so that the synchronous material preview (including the video material corresponding to the main server and the sub servers) can be realized at the local playing end of the main server, and the load and pressure of the main server can be reduced (the performance of the main server is reduced).
Further, the local playing end corresponding to the main server synchronously plays the low-code-stream material and the second original material corresponding to the first original material, and the method includes:
the main server acquires a low-code-stream material corresponding to the transcoded first original material, decodes and codes the low-code-stream material, and plays the coded low-code-stream material at the local playing end;
and simultaneously, after the main server confirms that the second original material is decoded and encoded, the second original material is played at the local playing end.
Understandably, in the process of implementing the material preview by the primary server, the material needs to be decoded and encoded (the decoding is a local decoding mode, that is, the primary server only decodes the low-code-stream material of the first original material corresponding to the secondary server, and the low-code-stream material needs to be displayed in the local playing end of the primary server), but because the primary server already implements the decoding and encoding of the second original material in the process of playing the material, the embodiment can implement the playing of the second original material after confirming that the decoding and encoding of the second original material are completed; specifically, the manner mentioned for decoding and encoding is consistent with the above, and is not described herein again, the decoding process can be roughly divided into channel transmission-entropy decoding-inverse quantization-inverse transformation-prediction, and the encoding process can be roughly divided into prediction-transformation-quantization-entropy coding; in this embodiment, the slave server does not need to transmit the first raw material back to the master server through a network or the like, and occupies the performance of the master server and the slave server.
In another embodiment, the obtaining, by the main server, a low-code-stream material corresponding to the transcoded first raw material includes: the main server judges whether the video played by the local playing end is a low-code-stream material; if the video is a low-code-stream material, the main server acquires a corresponding low-code-stream material after the first raw material is transcoded; and if the video is not a low-code-stream material, the local playing end plays the preset software pattern.
Further, before the main server obtains the low-code-stream material corresponding to the transcoded first raw material, the method further includes:
and generating the low-code-stream material according to the first original material, and after the low-code-stream material is bound with the first original material, determining that the low-code-stream material is led into the local playing end.
Understandably, a material binding window is arranged at the local playing end, and the low-code-stream material and the first original material can be bound through the material binding window no matter whether the generation mode of the low-code-stream material is transcoding from a third-party transcoding platform or autonomous transcoding of video software; specifically, after a first original material is added to a far-end playing end, a first original material array named by a first array is generated, and after a low-code-stream material is added to a material binding window, a low-code-stream material array named in accordance with the first array is generated to complete binding of the first original material of the low-code-stream material, for example, the first original material array named by the first array can be a [ 0 ], the low-code-stream material array named by the first array can be a [ 1 ], and the array of the second original material can be b [ 0 ]; after the binding is realized, the low-code stream material is guided into the local playing end.
In another embodiment, the generating the low-code-stream material according to the first raw material, after binding the low-code-stream material with the first raw material, determining that the low-code-stream material is imported to the local play end includes: leading the first raw material into a local playing end of the main server; after the import is determined to be successful, generating the low-code-stream material according to the first original material, binding the low-code-stream material with the first original material, and then determining that the low-code-stream material is imported into the local playing end so as to realize the import of the low-code-stream material into the local playing end; in this embodiment, the local play end of the main server has a limitation on maximum video play and processing capability, and when a high-code-stream first raw material, such as 8K, is successfully introduced into the local play end, it is determined that a low-code-stream material, such as 2K, can be successfully introduced into the local play end.
Further, the generating the low-code-stream material according to the first original material, after binding the low-code-stream material with the first original material and determining that the low-code-stream material is imported into the local playing end, further includes:
acquiring a first time length of the low code stream material;
acquiring a second time length of the first raw material;
when the difference value between the first time length and the second time length is determined to exceed the preset time length, prompting that the low-code-stream material is not the corresponding low-code-stream material after the first raw material is transcoded;
and when the difference value between the first time length and the second time length is determined not to exceed the preset time length, generating the low-code-stream material according to the first raw material, and after the low-code-stream material is bound with the first raw material, determining that the low-code-stream material is led into the local playing end.
Understandably, the first time length and the second time length refer to time lengths corresponding to material playing time, and after transcoding is performed through the third transcoding platform and the local playing end, the first time length and the second time length are generally equal or have a small difference; in the embodiment, whether the low-code-stream material added to the material binding window corresponds to the first original material is confirmed by comparing the time length difference, when the correspondence is confirmed, the low-code-stream material is substituted into the local playing end, so that the process of previewing the low-code-stream material is realized, when the correspondence is not confirmed, the low-code-stream material and the first original material are determined to have no corresponding relation, the low-code-stream material and the first original material are prompted to have no corresponding relation in a highlighting manner, and the local playing end in the main server is prevented from previewing wrong material contents.
Further, after the step S20, the method for previewing the server-based material further includes:
when the first original material and the second original material are different materials, determining whether a local playing end corresponding to the main server starts a playback function or not and whether a remote playing end corresponding to at least one slave server starts a playback function or not; the back display function is that a terminal connected with the main server displays the first original material and the slave server displays the second original material, and a local playing end of the main server and a far-end playing end of the slave server display low-code-stream materials;
when the master server and the slave servers are determined to start the playback function, at least one slave server plays a low-code-stream material corresponding to the first original material at a corresponding far-end playing end;
and the main server synchronously plays the low-code-stream material and the second original material corresponding to the first original material at the corresponding local playing end.
Understandably, the redisplay function is a relation set among the three devices, such as an LED display screen, a server and a terminal (a computer screen connected with the server), in the relation, the LED display screen displays original materials, the terminal displays low-code materials, and a playing end in the server is used for controlling the playing of the materials; the method comprises the steps that the method is placed in a main server and a secondary server, an LED display screen connected with the secondary server displays a first original material, a far-end playing end corresponding to the secondary server plays a low-code-stream material of the first original material, and an LED display screen connected with the main server displays a second original material, but a local playing end corresponding to the main server also plays the second original material and the low-code-stream material corresponding to the first original material (it needs to be stated that when the main server plays the low-code-stream material, a computer screen corresponding to the far-end playing end still plays the first original material all the time); when the playback function is started, the main server of the embodiment also plays the second original material at the local playing end, because the second original material is decoded and encoded, the performance of the main server is not occupied any more, and in order to ensure the display effect, the local playing end plays the second original material which is high-code stream (high resolution);
in another embodiment, the main server may not be connected to the terminal, but may play the second original material in a local play end of the main server.
In another embodiment, before determining that the first raw material and the second raw material are different materials, the method further includes: the secondary server judges whether a video (a first original material) is played at the terminal; if the video is not played at the terminal, the remote playing end does not play the video; if the video is played at the terminal, the secondary server judges whether the video played by the far-end playing end is a low-code-stream material; if the video is a low-code-stream material, the far end of the secondary server plays the low-code-stream material; and if the video is not a low-code-stream material, the remote playing end plays the preset software pattern.
In another embodiment, before determining that the echo function is turned on by both the master server and the slave server, the method further includes: when the fact that the main server and the slave servers do not start the playback function is determined, or the fact that the main server starts the playback function is determined, when the playback function is not started by at least one slave server, at least one slave server plays the first original material at a corresponding far-end playing end; the main server synchronously plays the low-code-stream material and the second original material corresponding to the first original material at the corresponding local playing end;
in another embodiment, before determining that the master server and the slave server both start the echo function, the method further includes: when it is determined that the playback function is not started by the master server and the playback function is started by at least one slave server, the at least one slave server plays the low-code-stream material corresponding to the first original material at the corresponding far-end playing end; and the main server synchronously plays the low-code-stream material and the second original material corresponding to the first original material at the corresponding local playing end.
Further, before determining that the first and second source materials are different materials, the server-based material preview method further includes:
when the first original material and the second original material are determined to be the same material and the first original material and the second original material are different materials, determining whether a local playing end corresponding to the main server starts a playback function or not and whether a remote playing end corresponding to at least one slave server starts a playback function or not;
when the fact that the playback function is not started by the main server and the playback function is started by the remote playing end corresponding to the at least one slave server is determined, the at least one slave server plays the low-code-stream material corresponding to the first original material at the corresponding remote playing end;
and the main server synchronously plays the first original material and the second original material at a corresponding local playing end.
When the main server of this embodiment does not open the playback function, the local play end of the main server plays the second original material because decoding and encoding have been completed in the process of the video material on-screen playing, so the local play end also plays the second original material, and the local play end of the main server previews the first original material corresponding to the secondary server because the first original material and the second original material are the same material and decoding and encoding of the first original material have been completed, so even if the main server does not open the playback function, the local play end still plays the second original material.
In another embodiment, before determining that the playback function is not started by the master server and that the playback function is started by a remote playback end corresponding to at least one of the slave servers, the method further includes: when it is determined that the playback function is not started by the remote playing ends corresponding to the master server and the slave servers or when it is determined that the playback function is started by the master server and the playback function is not started by the remote playing end corresponding to at least one of the slave servers, the at least one slave server plays the first original material at the corresponding remote playing end; the main server synchronously plays the first raw material and the second raw material at a corresponding local playing end;
in another embodiment, before determining that the playback function is not started by the master server and that the playback function is started by a remote playback end corresponding to at least one of the slave servers, the method further includes: when it is determined that the playback function is started by the master server and the playback function is started by the remote playing end corresponding to the at least one slave server, the at least one slave server plays the low-code-stream material corresponding to the first original material at the corresponding remote playing end; and the main server synchronously plays the first raw material and the second raw material at the corresponding local playing end.
