[0002] Applications with video playback or video editing functions usually provide a video seek function, which allows users to seek to play or edit video images at any playback time point, that is, jump from a video frame at one time point to a video frame at another time point. This function is achieved by decoding the video data packet from the video key frame before the seek time point until the video seek time point.

[0003] However, the process of decoding the video data packet consumes a lot of processing resources and time, resulting in poor user experience. The speed of obtaining the target positioning video frame of the user by decoding the video encoding data packet needs to be improved. Summary of the invention

[0037] Figure 1A flow chart of a video processing method provided in an embodiment of the present disclosure is provided. The embodiment of the present disclosure is applicable to scenarios of video playback or video editing, especially for videos in HEVC (High Efficiency Video Coding) encoding format, to achieve fast video playback content positioning (seek). The method can be executed by a video processing device, which can be implemented in the form of software and / or hardware, and optionally, by an electronic device, which can be a mobile terminal, a PC or a server, etc.

[0038] like Figure 1 As shown, the video processing method includes:

[0039] S110: Acquire a display time of a target positioning video frame, and determine a target key frame associated with the target positioning video frame based on the display time.

[0040] The target video frame can be any video frame in any video clip currently played or edited by the user. When watching or editing a video clip, the user can select and jump to any target video frame from the currently displayed video frame according to his / her viewing interest or editing concept, i.e., seek the target video frame. The implementation of the target video frame seek function can, to a certain extent, improve the viewing or editing freedom of the user when watching or editing a video.

[0041] The display time of the target positioning video frame, that is, the display timestamp (PresentationTimestamp, PTS) of the target positioning video frame. The target key frame associated with the target positioning video frame can be a key frame that is displayed before the target positioning video frame and is closest to the target positioning video frame. In dynamic image coding, the image screen (i.e., frame) is divided into three types: I, P, and B. I is an internal coding frame, P is a forward prediction frame, and B is a bidirectional interpolation frame. Among them, the I frame is a key frame, which can be understood as a complete picture. The target key frame is the I frame that is in front of the target positioning video frame and has the closest display time.

[0042] Specifically, when the application providing the video frame seek function obtains the user's video display content jump operation in the preset video display interactive interface, the display time of the target positioning video frame can be obtained. Usually, the user can drag the video display time progress bar in the preset video display interactive interface to a certain time point, or click a certain time point on the video display time axis to switch the currently displayed video frame to the target positioning video frame at the target display time point, so as to determine the display time of the target positioning video frame.

[0043] Further, after the display time of the target positioning video frame is determined, the target key frame associated with the target positioning video frame can be determined based on the display time. Exemplarily, the index table of the video key frames of the video to which the target positioning video frame belongs can be queried according to the display time to determine the target key frame associated with the target positioning video frame.

[0044] S120, reading each video frame compressed data packet in the video image group where the target key frame and the target positioning video frame are located, and determining a decoding dependency relationship between the video frame compressed data packets.

[0045] A video group of pictures (Group of Pictures, GOP) represents a group of continuous pictures in a video. The target key frame and the target positioning video frame are video frames in the same video group of pictures.

[0046] The first image of a GOP must be an I frame, that is, the target key frame is the first image frame of the video image group it is in. It can be understood that in this embodiment, the case where the target positioning video frame is the target key frame is not excluded.

[0047] In the video image group, in addition to the target key frame, there are also P frames and B frames. Among them, P is a forward prediction frame and B is a bidirectional interpolation frame. P frames and B frames record the changes relative to I frames. The decoding dependency between each video frame compression data packet can be understood as the reference relationship between each video frame and the video frame it refers to forward or backward during encoding. This reference relationship will be recorded in the corresponding video frame compression data packet in the form of data packet information header data.

[0048] Accordingly, when determining the decoding dependency between the compressed data packets of each video frame, it is necessary to parse the compressed data packets of each video frame, quickly obtain the information header of the data packet, and thus obtain the image sequence number corresponding to each video frame in the video image group and the image sequence number of the decoding reference video frame respectively. Further, the decoding dependency between the compressed data packets of each video frame is determined based on the image sequence number of each video frame in the video image group and the image sequence number of the decoding reference video frame.

[0049] Among them, the image sequence number (PictureOrderCount) is mainly used to identify the playback order of the image, and can also be used as the identification information of each video frame in the video image group, such as numbering 0, 1, 2, 3... in the playback order starting from the key frame. The decoding dependency represents the video frames that a video frame directly or indirectly references when encoding. For example, the POC of a video frame is 5, and its decoding reference video frames are video frames with POCs of 3 and 6, and the decoding reference video frame of the video frame with POC 3 is 2. Then, the decoding dependency that can be determined is that the decoding direct reference video frames of the video frame with POC 5 are 3 and 6, and the decoding indirect reference video frame is 3.

[0050] S130, determining a target data packet to be decoded in each of the video frame compressed data packets according to the decoding dependency relationship, and decoding the target data packet to be decoded to obtain the target positioning video frame.

[0051] Specifically, after determining the decoding dependency of each video frame sequence in the video image group, the target image sequence numbers of the video frames that the target positioning video frame directly and indirectly depends on can be determined according to the decoding dependency; then, the video frame compressed data packet corresponding to the target image sequence number is used as the target data packet to be decoded.

[0052] That is, in the present embodiment, only the compressed data packets of video frames related to the target positioning video frames and those having a decoding dependency thereon are decoded, and the compressed data packets of video frames having no decoding dependency thereon are not decoded, thereby reducing the number of compressed data packets of video frames to be decoded and improving the speed of decoding and displaying the target positioning video frames.

[0053] The technical solution of the disclosed embodiment is to determine the target key frame associated with the target positioning video frame based on the display time after obtaining the display time of the target positioning video frame; then, read the compressed data packets of each video frame in the video image group where the target key frame and the target positioning video frame are located, and determine the decoding dependency between the compressed data packets of each video frame; thereby determining the target data packet to be decoded in the compressed data packets of each video frame according to the decoding dependency, and decoding the target data packet to be decoded to obtain the target positioning video frame, that is, further filtering the compressed data packets that were originally decoded, and only decoding the compressed data packets of the video frames that have a direct or indirect decoding dependency relationship with the target positioning video frame, thereby improving the speed of positioning to jump to the target positioning video frame. The technical solution of the disclosed embodiment solves the problem that many data packets need to be decoded when positioning the target positioning video frame, thereby slowing the video positioning speed, and can reduce the number of video encoding data packets to be decoded in the process of positioning the target positioning video frame, shorten the time required for video positioning, and improve the efficiency of video positioning.

[0054] Figure 2 This is a flow chart of another video processing method provided by an embodiment of the present disclosure, which further describes the process of decoding dependency analysis of video frame compression data packets based on the above embodiment. The method can be executed by a video processing device, which can be implemented in the form of software and / or hardware, and optionally, by an electronic device, which can be a mobile terminal, a PC or a server, etc.

[0055] like Figure 2 As shown, the video processing method includes:

[0056] S210: Acquire a display time of a target positioning video frame, and determine a target key frame associated with the target positioning video frame based on the display time.

[0057] S220, reading compressed data packets of each video frame in the video image group where the target key frame and the target positioning video frame are located, and parsing the compressed data packets of each video frame to obtain the image sequence number corresponding to each video frame in the video image group and the image sequence number of the decoding reference video frame respectively.

[0058] Specifically, when parsing each video frame compressed data packet, each video frame compressed data packet can be read and parsed to obtain the image sequence number of the corresponding video frame and the image sequence number of the decoding reference video frame of the video frame. Alternatively, all the video frame compressed data packets to be read can be read and then the video compressed data packets can be parsed uniformly.

[0059] Furthermore, when reading a video frame compressed data packet, it is necessary to determine once each time a video frame compressed data packet is read whether the reading of all the video frame compressed data packets that need to be read is completed. If so, the next step can be performed; otherwise, it is necessary to continue to read the next video frame compressed data packet. Among them, the condition for determining whether the reading process of all the video frame compressed data packets that need to be read is completed can be to determine whether the display timestamp of the read video frame compressed data packet is after the display time of the target positioning video frame, and whether the read video frame compressed data packet is the last video frame compressed data packet of the image sequence in the video image group where the target key frame is located. Alternatively, it can also be determined whether the read video frame compressed data packet is the last video frame compressed data packet in the entire video clip.

[0060] When determining the decoding dependency between the compressed data packets of each video frame, the information header of the data packet is quickly obtained by parsing the compressed data packets of each video frame, thereby obtaining the image sequence number corresponding to the video frame recorded in the information header of each compressed data packet of each video frame and the image sequence number of the decoding reference video frame. Further, the decoding dependency between the compressed data packets of each video frame is determined based on the image sequence number of each video frame in the video image group and the image sequence number of the decoding reference video frame.

[0061] S230: Construct a decoding dependency graph based on the image sequence number of each video frame in the video image group and the image sequence number of the decoding reference video frame.

[0062] In this step, by constructing a decoding dependency graph, the decoding dependency between video frames is more intuitively represented in a graphical manner, thereby improving the efficiency of data relationship storage and management to a certain extent.

[0063] In a feasible implementation, the decoding dependency graph can be presented in the form of a directed acyclic graph, which can be referred to as Figure 3 The example directed acyclic graph.

[0064] S240. Determine the direct or indirect decoding dependency relationship between the video frame compression data packets according to the decoding dependency graph.

[0065] Specifically, based on the connection relationship between the decoding dependent video frames of each video frame in the decoding dependency graph, the direct or indirect decoding dependency relationship between the compressed data packets of each video frame can be determined.

[0066] Still Figure 3 For example, in Figure 3 A group of GOPs containing 9 image frames is shown in FIG. Among them, I0 is the first key frame; P1 frame decoding directly depends on I0 frame, B2 frame decoding directly depends on I0 frame and P1 frame; B3 frame decoding directly depends on I0 frame; B4 frame decoding directly depends on B2, P1 and B3 frames, and indirectly depends on I0 frame; P5 frame decoding directly depends on P1 frame, and indirectly depends on I0 frame; B6 frame decoding directly depends on B2, P1 and P5 frames, and indirectly depends on I0 frame; B7 frame decoding directly depends on B6 and P1 frames, and indirectly depends on I0 and P5 frames; B8 frame decoding directly depends on B6 and P5 frames, and indirectly depends on I0, B2, P1 and P5 frames.

[0067] S250, determining a target data packet to be decoded in each of the video frame compressed data packets according to the decoding dependency relationship, and decoding the target data packet to be decoded to obtain the target positioning video frame.

[0068] From the decoding dependency of the video frames sorted out in the previous step, the image sequence numbers of the directly and indirectly dependent video frames can be extracted from the image sequence number of the target positioning video frame, thereby determining the target data packet to be decoded. The target data packet to be decoded is further decoded, and the target positioning video frame is rendered and displayed based on the decoding result.

[0069] The technical solution of the disclosed embodiment is to determine the target key frame associated with the target positioning video frame based on the display time after obtaining the display time of the target positioning video frame; then, read the compressed data packets of each video frame in the video image group where the target key frame and the target positioning video frame are located, parse the compressed data packets of each video frame and construct a decoding dependency graph based on the image sequence number of each video frame in the video image group and the image sequence number of the decoding reference video frame; thereby determining the target data packet to be decoded according to the decoding dependency graph, and decoding the target data packet to be decoded to obtain the target positioning video frame, that is, further filtering the compressed data packets that were originally decoded, and only decoding the compressed data packets of the video frames that have a direct or indirect decoding dependency relationship with the target positioning video frame, thereby improving the speed of positioning jumping to the target positioning video frame. The technical solution of the disclosed embodiment solves the problem that many data packets need to be decoded when positioning the target positioning video frame, thereby slowing the video positioning speed, and can reduce the number of video encoding data packets to be decoded during the positioning process of the target positioning video frame, shorten the time required for video positioning, and improve the efficiency of video positioning.

[0070] Figure 4 This is a flow chart of another video processing method provided by an embodiment of the present disclosure. On the basis of the above embodiment, it further describes the process of managing the compressed data packets of each video frame in the video image group through a data queue during the video processing. The method can be executed by a video processing device, which can be implemented in the form of software and / or hardware, and optionally, by an electronic device, which can be a mobile terminal, a PC or a server, etc.

[0071] like Figure 4 As shown, the video processing method includes:

[0072] S310: Acquire a display time of a target positioning video frame, and determine a target key frame associated with the target positioning video frame based on the display time.

[0073] S320, starting from the video frame compression data packet of the target key frame, sequentially read the video frame compression data packets in the video image group and store them into a preset first-in-first-out data queue, until all the video frame compression data packets belonging to the video image group are stored in the preset first-in-first-out data queue.

[0074] In this embodiment, the video frame compression data packets are managed by the data queue, so that the order of data packet management can be achieved, and the disorder and omission of data sequence will not occur during the processing of the video frame compression data packets.

[0075] Specifically, after each video frame compressed data packet is read and written into the preset first-in-first-out data queue, step S330 may be executed to parse the video frame compressed data packet written into the queue, and determine whether the reading of all video frame compressed data packets has been completed. If not, S320 and S330 are repeatedly executed until all video frame compressed data packets to be read are written into the preset first-in-first-out data queue, and the parsing of the video frame compressed data packets is completed.

[0076] S330, parsing the compressed data packets of each video frame to obtain the image sequence number corresponding to each video frame in the video image group and the image sequence number of the decoding reference video frame respectively.

[0077] S340: Determine a decoding dependency relationship between the compressed data packets of the video frames based on the image sequence number of each video frame in the video image group and the image sequence number of the decoding reference video frame.

[0078] In this step, a decoding dependency graph can be constructed to more intuitively represent the decoding dependency between video frames in a graphical manner. Figure 3 The example directed acyclic graph.

[0079] S350, sequentially reading each stored video frame compression data packet from the preset first-in-first-out data queue, and determining whether the read video frame compression data packet is a video frame compression data packet that the target positioning video frame directly or indirectly depends on based on the decoding dependency relationship.

[0080] According to the order of writing into the preset first-in-first-out data queue, the stored compressed data packets of each video frame are read in sequence, and the compressed video data packets that need to be decoded are filtered.

[0081] For each video frame compressed data packet taken out from the preset FIFO data queue, it is determined whether it is a video frame compressed data packet directly or indirectly dependent on the target positioning video frame in the decoding dependency relationship according to the POC of the data packet. If so, step S360 can be executed.

[0082] S360. When the read video frame compression data packet is a video frame compression data packet that the target positioning video frame directly or indirectly depends on, the video frame compression data packet is decoded until all the video frame compression data packets in the preset first-in-first-out data queue are read and processed to obtain the target positioning video frame.

[0083] In addition, when the read video frame compressed data packet is not the video frame compressed data packet that the target positioning video frame directly or indirectly depends on, it is filtered out, and S350 is repeated to read the next video compressed data packet. The filtered video frame compressed data packet will not be decoded, thereby reducing the time required for positioning the target positioning video frame.

[0084] It should be noted here that in the video playback scenario, the video object for locating the target video frame based on the video processing method provided by this embodiment is mostly a single video clip. In the video editing scenario, especially the video editing scenario for video synthesis through multiple video clips, during the video editing preview process, when locating (seeking) the target video frame, the video processing method provided by this embodiment will be used synchronously in multiple video clips (i.e., including multiple processed video objects at the same time), and the target video frame will be located respectively, and the preview target video frame will be synthesized based on multiple target video frames of the same display time.

[0085] The technical solution of the disclosed embodiment is as follows: after obtaining the display time of the target positioning video frame, a target key frame associated with the target positioning video frame is determined based on the display time; then, the video frame compression data packets are managed in a data queue manner, starting from the video frame compression data packet of the target key frame, the video frame compression data packets in the video image group are read in sequence and stored in a preset first-in-first-out data queue, until all the video frame compression data packets belonging to the video image group are stored in the preset first-in-first-out data queue, and the decoding dependency relationship between the video frame compression data packets is determined; thereby, the stored video frame compression data packets are read in sequence from the preset first-in-first-out data queue, and it is determined whether the read video frame compression data packet is a video frame compression data packet directly or indirectly dependent on the target positioning video frame according to the decoding dependency relationship, so as to determine the target data packet to be decoded, and the target data packet to be decoded is decoded to obtain the target positioning video frame, that is, the compressed data packets that were originally decoded are further filtered, and only the video frame compression data packets that have a direct or indirect decoding dependency relationship with the target positioning video frame are decoded, thereby improving the speed of positioning jumping to the target positioning video frame. The technical solution of the disclosed embodiment solves the problem that many data packets need to be decoded during target positioning video frame positioning, resulting in slow video positioning speed. It can reduce the number of video encoding data packets to be decoded during target positioning video frame positioning, shorten the time required for video positioning, and improve video positioning efficiency.

The device is suitable for scenarios of video playback or video editing, especially for achieving fast video playback content positioning (seek). The video processing device can be implemented in the form of software and / or hardware and can be configured in an electronic device, which can be a mobile terminal, a PC or a server, etc.

[0089] The technical solution of the disclosed embodiment is to determine the target key frame associated with the target positioning video frame based on the display time after obtaining the display time of the target positioning video frame; then, read the compressed data packets of each video frame in the video image group where the target key frame and the target positioning video frame are located, and determine the decoding dependency between the compressed data packets of each video frame; thereby determining the target data packet to be decoded in the compressed data packets of each video frame according to the decoding dependency, and decoding the target data packet to be decoded to obtain the target positioning video frame, that is, further filtering the compressed data packets that were originally decoded, and only decoding the compressed data packets of the video frames that have a direct or indirect decoding dependency relationship with the target positioning video frame, thereby improving the speed of positioning to jump to the target positioning video frame. The technical solution of the disclosed embodiment solves the problem that many data packets need to be decoded when positioning the target positioning video frame, thereby slowing the video positioning speed, and can reduce the number of video encoding data packets to be decoded in the process of positioning the target positioning video frame, shorten the time required for video positioning, and improve the efficiency of video positioning.

[0092] The decoding dependency relationship between the compressed data packets of the video frames is determined based on the image sequence number of each video frame in the video image group and the image sequence number of the decoding reference video frame.
