Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present description. This description may be implemented in many ways other than those specifically set forth herein, and those skilled in the art will appreciate that the present description is susceptible to similar generalizations without departing from the scope of the description, and thus is not limited to the specific implementations disclosed below.
The terminology used in the description of the one or more embodiments is for the purpose of describing the particular embodiments only and is not intended to be limiting of the description of the one or more embodiments. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used in one or more embodiments of the present specification refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It will be understood that, although the terms first, second, etc. may be used herein in one or more embodiments to describe various information, these information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, a first can also be referred to as a second and, similarly, a second can also be referred to as a first without departing from the scope of one or more embodiments of the present description. The word "if," as used herein, may be interpreted as "at … …" or "when … …" or "in response to a determination," depending on the context.
First, the noun terms to which one or more embodiments of the present specification relate are explained.
Internet Protocol (IP, Internet Protocol): is a network layer protocol in the TCP/IP architecture. Among them, TCP/IP (Transmission Control Protocol/Internet Protocol) refers to a Protocol cluster that can realize information Transmission among a plurality of different networks. The IP has the functions of improving the expandability of the network and realizing interconnection and intercommunication of large-scale and heterogeneous networks. IP is the foundation that forms the internet and can provide information of various protocols, such as TCP, UDP, etc., to the transport layer; the IP packets may be placed at the link layer and transmitted via various technologies such as ethernet, token ring, etc.
IP network: the connected networks are implemented according to an internetworking protocol. For example, communication between different networks, such as an ethernet network, a packet switched network, etc., may be implemented according to an internetworking protocol.
IP conversion: which means converting various types of data (analog signal data, digital signal data, etc.) into IP packets conforming to the internet protocol. The IP data packets may be transmitted based on a general internet infrastructure (e.g., a router, a switch, a communication network, etc.), and may be stored in a general storage device (e.g., a flash disk, a hard disk, a removable hard disk, a network attached storage, etc.). Network Attached Storage (NAS): a device connected to a network and having a data storage function is also called a "network storage". The NAS is a special data storage server, takes data as a center, thoroughly separates storage equipment from the server, and centrally manages the data, thereby releasing bandwidth, improving performance and reducing total cost of ownership.
Digital component Serial Interface (SDI): a digital video interface standard. The interface of the SDI is mainly determined according to the transmission rate, for example, the HD-SDI interface is a high definition digital input and output port of a broadcasting stage, where HD represents a high definition signal. The SDI serial interface is an interface that sequentially transfers the bits of a data word and the corresponding data through a single channel. Since the data rate of serial digital signals is high, it must be processed before transmission. Since the SDI interface cannot directly transmit the compressed digital signal, the compressed signal recorded by the digital video recorder, the hard disk, etc. must be decompressed and output through the SDI interface before entering the SDI system. If decompression and compression are repeated, image quality degradation and delay increase are caused, and for this reason, digital video recorders and nonlinear editing systems of various formats have specified their own interfaces for directly transmitting compressed digital signals.
Network device Interface (NDI, network device Interface): and audio and video coding and decoding and a network transmission protocol interface based on UDP. NDI allows traditional video signals to be reliably transmitted and stored in an IP network-based infrastructure without requiring complex wiring. NDI may implement two functions, a first function of encoding compression and decoding video, and a second function of low-latency transmission based on the first function. Wherein the encoding and decoding of the NDI may include: the coding is to code the audio and video signals into NDI network flow to enter a switch or a PC, and then the NDI network flow is discovered and called by the PC or software in the network; and in the decoding process, the NDI is controlled to decode and restore the NDI stream in the network (when the NDI stream is many, only 1 NDI stream needs to be decoded by one NDI box) into an SDI/HDMI signal, and the SDI/HDMI signal is output to a local display, a television, a recorder or other devices or terminals needing the SDI/HDMI signal through the NDI box. HDMI refers to a High Definition Multimedia Interface (HDMI), which is a fully digital video and audio transmission Interface capable of transmitting uncompressed audio and video signals. The HDMI can be used for set-top boxes, DVD players, personal computers, televisions, game hosts, comprehensive amplifiers, digital stereos, televisions and other equipment. HDMI can send audio frequency and video signal simultaneously, because audio frequency and video signal adopt same wire rod, can simplify the installation degree of difficulty of system's circuit greatly.
Agent materials: and the original video material is replaced by the proxy material with smaller data volume and unchanged content through automatic transcoding and calling of the proxy software. On the basis, the proxy material can be edited, the editing result is applied to the large video material, and finally the target video without influencing the video quality is output.
Drawing transmission: the image is accurately and quickly transmitted. The current common image transmission technologies include MPEG-2, MPEG-4, etc., which simply compress the image to focus on the transmission.
Metadata (Metadata): the data (data about data) describing data, also called intermediate data and relay data, is mainly information describing data property (property) and is used for supporting functions such as indicating storage location, history data, resource searching, file recording and the like. Metadata is an electronic catalog, and in order to achieve the purpose of creating a catalog, the contents or features of data must be described and collected, so as to achieve the purpose of assisting data retrieval.
Illustratively, referring to fig. 1, fig. 1 shows an exemplary video processing flow in a movie scene, which may specifically include the following steps: a post-clipping flow and a live shooting flow. Wherein, the scene is shot the flow and is included: the video camera collects videos, the videos are sent to the image transmission sending end through the SDI cable, the image transmission sending end sends the videos to the image transmission receiving end through wireless transmission, the images are sent to the field monitor through the SDI cable by the image transmission receiving end, and then the scene related personnel can monitor and review the shot videos through the field monitor. The post-clipping flow includes: the method comprises the following steps that a video collected by a camera is written into a storage card during shooting, after the video is collected, the storage card is taken out of the camera, and the storage card is copied and proxy materials are obtained; the method comprises the following steps that a storage card is used for storing a video, wherein the disc copying refers to reading the video from the storage card, and the proxy material acquisition refers to carrying out automatic transcoding calling on the read video through proxy software to obtain a proxy material; further, storing videos obtained by copying, namely original materials and proxy materials, into an NAS storage matrix; the editing personnel can acquire agent materials and original materials from the NAS storage matrix; and editing the proxy material, and sleeving the editing result back to the original material to obtain the film. In the video processing flow shown in fig. 1, video processing such as editing relies on manual transcoding and unloading of a memory card, and operations can only be performed after shooting is completed, and cannot be performed in parallel with movie and television play shooting, resulting in low video processing efficiency.
In order to improve video processing efficiency, in the present specification, a video processing method is provided, and the present specification relates to a video processing apparatus, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.
Referring to fig. 2, fig. 2 shows a flowchart of a video processing method provided in an embodiment of the present specification, which is applied to a transcoding unit, and specifically includes the following steps:
s202, in the process of video acquisition by the camera, acquiring an original video acquired by the camera.
In a specific application, the transcoding unit is connected with a camera. The specific connection mode may be various, depending on the specific form of the transcoding unit. For example, when the transcoding unit is a software module, the transcoding unit may be disposed in an output port of the camera or a network interface of a communication network that communicates according to an internet protocol, and the network interface is connected to the camera. Or, for example, when the transcoding unit is a hardware device, the transcoding unit may be independent from the camera and the communication network and connected to the camera and the communication network, respectively. Moreover, the process of the camera performing video capture may include: the camera starts the process from the video acquisition to the process before the video acquisition is finished. Therefore, the step S202 can achieve the effect of instantly acquiring the video captured by the camera: when the video is acquired by the camera, the currently acquired video is acquired without waiting for the video acquisition to be finished. Thus, video processing efficiency can be ensured. In the process of video acquisition by the camera, the transcoding unit may acquire the original video acquired by the camera in various ways.
In an alternative embodiment, the output interface of the camera is connected to a network device interface of the communication network, wherein the network device interface comprises a transcoding unit;
accordingly, acquiring the original video acquired by the camera may specifically include the following steps:
receiving an original video collected by a camera by using a network equipment interface;
the original video is input to a transcoding unit.
The network device interface may be an NDI. Therefore, the NDI in the form of hardware equipment, namely an encoder, can be directly and externally connected to the video camera, and the SDI output of the video camera is received and is also the original video. Furthermore, NDI IP the received data by the included transcoding means: original video in the form of an SDI signal is transcoded into transcoded video data in the form of an NDI signal. Therefore, the original video is obtained and transcoded through the NDI in the form of the hardware device, and a code for transcoding the video according to the Internet interconnection protocol does not need to be additionally arranged, so that the method is more convenient and faster.
For example, the camera may actively output the captured video to the transcoding unit when the video is captured, so that the transcoding unit may receive the video, i.e., the original video. Or, for example, when it is monitored that the camera starts to capture video, the transcoding unit may request, according to a preset period, the video captured by the camera in the preset period from the camera, so that the transcoding unit may receive the original video. It is reasonable that any mode that can acquire the original video acquired by the camera in the process of video acquisition by the camera can be used in the present description, and this embodiment does not limit this.
S204, transcoding the original video according to the Internet protocol to obtain transcoded video data with a data format conforming to the Internet protocol.
In a specific application, transcoding is performed on an original video according to an internet protocol to obtain transcoded video data having a data format conforming to the internet protocol, and the original video is subjected to IP conversion to obtain an IP data packet capable of being transmitted in a communication network communicating according to the internet protocol. In this embodiment, the IP data packet is the transcoded video data, so that the transcoded data can be uploaded to the communication network and obtained by the video processing device accessing the communication network. Also, the IP packet may be suitable for a video processing device, such as a mobile terminal, a portable notebook, a desktop computer, and the like.
Compared with the data transmitted by the SDI, the original video collected by the camera can be received and processed by the video processing device instead of being limited to the monitor at the movie and television play shooting site. In one case, in order to ensure that the subsequent video processing is more accurate based on the video processing performed by the transcoded video data, the transcoding unit may further obtain metadata of the original video. This is described in detail below in the form of alternative embodiments for ease of understanding and reasonable layout.
And S206, uploading the transcoded video data to a communication network communicating according to an Internet protocol.
In particular applications, communication networks that communicate in accordance with the internet protocol may be varied. Illustratively, the communication network may be a wireless communication network: a WIFI network, a local area network of a video shooting site where the camera is located, an Ethernet and the like. In one case, the communication network communicating according to the internet protocol is a target wireless communication network; accordingly, after the transcoding unit uploads the transcoded video data to the target wireless communication network, the target wireless communication network can broadcast the transcoded video data.
The target wireless communication network can be a WIFI network on the video shooting site where the camera is located, and the NDI signal, namely the transcoded video data, can be broadcasted and outputted in the WIFI network in the embodiment. In this way, additional connection devices, such as signal transmission lines and the like, between the communication network and the transcoded video data are not required. And, the access of this WIFI network can increase the authority, like this, direct broadcast can, convenient high efficiency more. Therefore, through IP conversion of the original video, the transcoded video data can be suitable for video processing equipment, and compared with the video data directly transmitted through a graph transmission module for realizing graph transmission, the problem that the transmitted data can only be identified by industrial professional equipment such as a monitor and the like and can be identified by video processing equipment such as computers, mobile phones and the like can be avoided.
One embodiment of the present specification transcodes an original video collected by a camera into transcoded video data conforming to an internet protocol by a transcoding unit, and the data conforming to the internet protocol has universality. Therefore, the transcoded video data can be guaranteed to be suitable for computing devices such as video processing devices. On the basis, the transcoded video data are uploaded to a communication network which communicates according to an internet protocol, and then computing equipment such as video processing equipment and the like do not need to wait for the camera to finish video acquisition and finish reading of an original video from a storage medium of the camera, but can directly acquire the transcoded video data from the communication network in the video acquisition process, so that video processing is performed based on the transcoded video data. Therefore, the scheme can improve the video processing efficiency.
In an optional implementation manner, before uploading the transcoded video data to a communication network communicating according to an internet protocol, the video processing method provided in this embodiment of the present specification may further include the following steps:
receiving an original video collected by a camera, and extracting metadata of the original video;
transcoding the metadata according to an internet protocol to obtain transcoded metadata of which the data format conforms to the internet protocol;
accordingly, the uploading the transcoded video data to a communication network communicating according to an internet protocol may specifically include the following steps:
the transcoded video data and the transcoded metadata are uploaded to a communication network communicating according to an internetworking protocol.
In a specific application, metadata of an original video is used to describe attribute information of the original video. In this embodiment, in order to ensure that the transcoding metadata can be used to process the transcoded video data into proxy material, the attribute information described by the metadata of the original video may include: the video time length information comprises information representing uniqueness of an original video, information representing time length relation between each video frame in the original video and the video, and the like. For example, the information representing the uniqueness of the original video may be a name of the original video, and the information representing the relationship between each video frame in the original video and the video duration may be a time code of the original video. For example, video frame F1 corresponds to video duration time 10 th second. And, in order to ensure that the metadata can be transmitted and used, the metadata is transcoded, similar to the original video, to obtain transcoded metadata with a data format conforming to the internet protocol. In the scenario where the transcoding unit is included in the NDI, to implement this embodiment, a module for extracting metadata of the original video may be provided in the NDI. Also, the NDI may be configured to transcode the metadata according to an internet protocol.
Therefore, in a scene that an output interface of the camera includes the image transmission module to improve the image transmission efficiency, the embodiment can ensure that the data uploaded to the communication network includes the complete metadata of the original data, thereby reducing the metadata loss of the original video caused by image transmission and further causing the problem that the proxy material cannot be obtained subsequently.
In an optional implementation manner, before the acquiring of the original video captured by the camera, the video processing method provided in the embodiment of this specification may further include the following steps:
acquiring the transmission bandwidth of a communication network and the bandwidth occupation amount of a camera;
determining the load quantity matched with the transmission bandwidth based on the transmission bandwidth and the bandwidth occupation quantity;
according to the load quantity, the connection with a plurality of cameras is established.
In specific application, the load number matched with the transmission bandwidth is determined based on the transmission bandwidth and the bandwidth occupation amount, so that the number of a plurality of cameras for subsequently establishing connection can be ensured, and the load number can be matched with the transmission bandwidth of a communication network. Therefore, under the condition of accessing a plurality of cameras, the condition that the accessed load quantity exceeds the load capacity of the communication network can be avoided, and the normal work of the communication network and the cameras can be ensured. And establishing connections with the plurality of cameras according to the number of the loads, wherein the number of the plurality of cameras is less than or equal to the number of the loads. Therefore, the access of the plurality of cameras is controlled through the transcoding unit, and compared with the video processing flow shown in the figure 1, the video processing method does not need to additionally configure equipment in a field shooting flow every time one camera position (camera) is added, so that the convenience of video processing can be greatly improved, and the equipment cost is reduced.
Referring to fig. 3, fig. 3 is a flowchart illustrating another video processing method according to an embodiment of the present disclosure, which is applied to a video processing device accessing to a communication network, where the communication network communicates according to an internet protocol, and specifically includes the following steps:
and S302, receiving the transcoded video data sent by the transcoding unit through a communication network, wherein the transcoded video data is obtained by transcoding the original video acquired by the camera according to an Internet interconnection protocol in the video acquisition process of the camera by the transcoding unit.
In a specific application, a process of acquiring the transcoded video data by the transcoding unit and a communication network in this embodiment are respectively the same as the process of acquiring the transcoded video data by the transcoding unit and the communication network in the embodiment of fig. 2, and details are not repeated here, and are described in the embodiment of fig. 2. Also, the video processing apparatus may be various, for example, the video processing apparatus may be a mobile terminal, a desktop computer, a portable computer, or the like. The video processing device may receive the transcoded video data sent by the transcoding unit through a communication network in various ways. In an optional embodiment, the communication network is a target wireless communication network;
correspondingly, the receiving the transcoded video data sent by the transcoding unit through the communication network specifically includes the following steps:
and receiving the transcoded video data broadcasted by the target wireless communication network, wherein the transcoded video data is uploaded to the target wireless communication network by the transcoding unit.
The target wireless communication network can be a WIFI network on the video shooting site where the camera is located, and the NDI signal, namely the transcoded video data, can be broadcasted and outputted in the WIFI network in the embodiment. In this way, additional connection devices, such as signal transmission lines and the like, between the communication network and the transcoded video data are not required. And, the access of this WIFI network can increase the authority, like this, direct broadcast can, convenient high efficiency more.
S304, video processing data are obtained based on the transcoded video data.
In a specific application, the video processing data is data obtained by processing the encoded video data, and may be various. For this reason, the manner of obtaining video processing data based on transcoding video data may be various. Illustratively, the transcoded video may be decoded according to an internet protocol, and the original video obtained by decoding is used as the video processing data. Or, for example, metadata extraction may be performed on the transcoded video data, the transcoded video data may be compressed, and the compressed transcoded video data and metadata, that is, the proxy material, may be used as the video processing data. On this basis, efficient video clipping can be performed using proxy material. Or, for example, the transcoded video may be decoded according to the internet protocol, and the original video obtained by decoding may be subjected to toning, clipping, and the like. In addition, the video processing equipment can directly clip the proxy material, and then the clipping result is looped back to the original video obtained after decoding, so that the target video such as cost is obtained. Alternatively, the video processing apparatus may transmit the proxy material and the transcoded video data to a dedicated video clipping apparatus, and the video clipping apparatus performs video clipping to obtain the target video. The proxy material can be transcoded according to the internet protocol and then sent.
In one case, in a scene in which an output interface of a camera includes a map transmission module to improve image transmission efficiency, an original video is a video subjected to map transmission compression, and therefore, metadata is likely to be missing, which may cause a problem that subsequently obtained proxy materials are inaccurate and cannot be used for video editing. In this regard, in an alternative embodiment, the video processing data includes target proxy material for video clips;
accordingly, before obtaining video processing data based on the transcoded video data, the video processing method provided in this embodiment of the present specification may further include the following steps:
receiving metadata of the transcoded video data sent by the transcoding unit through a communication network;
correspondingly, the obtaining of the video processing data based on the transcoded video data may specifically include the following steps:
and decoding the transcoded video data, performing data volume compression on a decoding result, and taking the compressed transcoded video data and metadata of the transcoded video data as a target proxy material.
Illustratively, the source material is a material with a resolution of 4K, the file name of the source material is c001.mp4, the video duration is 10 seconds, and the time codes are 90001000 to 90011000. Then, the target agent material may include: and compressing the data volume of the decoding result to obtain a material with the resolution of 1080P, wherein the file name is C001-proxy.mp4, the video time length is also 10 seconds, and the time code is 90001000-90011000. The time code is a corresponding mark of a video frame and a video duration of the material, and can prevent the dislocation of the video frame. For example, the time code 90001000 represents the 1 st second corresponding video frame F0. On this basis, the video processing device may perform the following clipping operation on the C001-proxy. mp4 file: the duration between the 2 nd and 7 th seconds, i.e., the video frames between 90002000 and 90007000, are truncated and the brightness is boosted by 50%. The clipping operation produces a clipping result: files describing the above-described clipping operations are described. And utilizing the editing result to perform loop back on the original material: the operation described by the clipping result is automatically attached to the above-mentioned c001.mp4 file, that is, the original material, by the agent software, and the target video is obtained. Wherein, the original material is the original video in this specification: and decoding the transcoded video data to obtain an original video.
The embodiment can ensure that the data uploaded to the communication network contains the complete metadata of the original data, thereby reducing the problem that proxy materials cannot be obtained subsequently due to the metadata loss of the original video caused by image transmission. Thus, implementation of efficient clipping can be guaranteed. And, the target proxy material can be acquired without waiting for the video capture to end and reading data from the memory card of the camera. On the basis, the target agent materials can be directly utilized to carry out video editing, the step of storing the target agent materials into the NAS storage matrix and then reading the target agent materials from the NAS storage matrix is not needed, and the video processing can be more efficient.
In one embodiment of the present description, an original video collected by a camera is transcoded into transcoded video data compliant with an internet protocol by a transcoding unit, and the data compliant with the internet protocol has universality. Therefore, the transcoded video data can be guaranteed to be suitable for computing devices such as video processing devices.
