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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
In the prior art, most of video recordings stored by a household camera are generally recordings recorded by a camera head stored on an SD card, and video frames cannot be efficiently transmitted during playback. For example, when playing is performed in a fast forward manner, if fast forward playback is performed, each video frame needs to be acquired and decoded, and for video frames that do not need to be displayed, the video frames are discarded after transmission and decoding are completed, which greatly wastes network resources and reduces the video data transmission rate. In view of the foregoing technical defects, embodiments of the present application provide a video processing scheme, where virtual I frames are inserted at intervals between P frames corresponding to I frames to encode a target video, and during playback, a video storage end can transmit only video frames to be displayed according to a playing requirement, so as to improve video network transmission efficiency.
Fig. 1 is a flowchart of a video processing method according to an embodiment of the present disclosure. Referring to fig. 1, the video processing method is applied to a video storage side, and includes:
s11: and coding the target video of the video storage end in a mode of inserting virtual I frames between P frames corresponding to the I frames at intervals to obtain the target video comprising the I frames, the virtual I frames and the P frames.
In this embodiment, a target video at the video storage end is encoded by inserting virtual I frames between P frames corresponding to the I frames at intervals to obtain the target video including the I frames, the virtual I frames, and the P frames. Currently, most of the camera heads adopt the coding method for the stored video that all the P frames after the I frame refer to the previous P frame, as shown in fig. 2, so that when the video is played back, the displayed video frame is determined by the playing end, and the decoding display end is played back at the same time, and when the subsequent P frame is decoded, all the P frames referred to in the front need to be decoded at the same time, which results in the need of acquiring all the video frames and increases the network transmission burden. The P frames in the subsequent I frame interval of the target video are separated by a plurality of dummy I frames in the present embodiment, the P frames in the dummy I frame interval refer to the dummy I frames, and the dummy I frames refer to the previous I frames, as shown in fig. 3. It is understood that the number of P frames in the adjacent virtual I frame interval may be set to 2 to 4, and is determined according to actual service requirements, which is not limited in this embodiment of the present application.
In this embodiment, an H264 compression technique may be used to encode a target video at the video storage end to obtain the target video including the I frame, the virtual I frame, and the P frame. The H264 encoder supports a virtual I frame or frame skipping mode, and all P frames in the I frame are prevented from referring to the previous P frame through the H264 encoding mode. The H264 compression technology is a video compression standard, can still provide a standard with good video quality at a lower bit rate, has relatively low design complexity, has a high video compression ratio and network affinity, and is applicable to various transmission networks.
S12: and constructing a corresponding time point index table based on the time points of the I frame and the virtual I frame in the target video.
In this embodiment, after the target video including the I frame, the virtual I frame, and the P frame is acquired, a corresponding time point index table is constructed based on time points of the I frame and the virtual I frame in the target video. Of course, the offset points of the I frame and the virtual I frame may be generated simultaneously in order to enable fast localization of the target video. The above steps are also the process of writing the video to the local storage device by the camera.
Further, when the I frame and the virtual I frame are encoded, the picture static states of the frames before and after encoding may also be written into an index table, that is, the time point index table may also include the picture states of the video frames before and after the I frame and the virtual I frame; wherein the picture state is used for reflecting whether the picture of the corresponding video frame changes. In playing back the target video, whether transmission of a still picture needs to be skipped or not can be selected according to the picture states of the preceding and following video frames. In addition, in this embodiment, whether a picture of the video frame changes may be determined according to inter-frame brightness between the video frames, so as to determine the picture state of the video frame. Of course, other technical means for determining whether the frame has a changed state, besides the change of the brightness difference between frames, are also within the scope of the disclosure of the present embodiment.
S13: and acquiring a playing requirement of a playing end for playing back the target video, and searching the I frame or the virtual I frame corresponding to the playing requirement from the time point index table to be used as an initial transmission frame.
In this embodiment, a play requirement for playing back the target video by the play end is obtained first, where the play requirement may be a fast forward speed, a play time point, whether to play a still picture, and the like, for example, by issuing the fast forward speed to the camera, the target video is not played after consecutive multiple frames of still pictures, and the play time point. The playback end may be a Personal Computer (PC), a mobile phone App, a Network Video Recorder (NVR), or the like. Then, the I frame or the virtual I frame corresponding to the playing requirement is looked up from the time point index table to be used as a starting transmission frame, for example, the I frame or the virtual I frame used as the starting transmission frame may be looked up from the time point index table according to the playing time point in the playing requirement. It is understood that the starting transmission frame is also the starting video frame for transmitting the target video.
S14: and transmitting the initial transmission frame and the video frame after the initial transmission frame to the playing end so that the playing end displays the received video frame.
In this embodiment, after the initial transmission frame is determined, the video frame after the initial transmission frame may be transmitted to the playing end, so that the playing end decodes and displays the received video frame. It can be seen that whether the frames are displayed or not is determined by the video storage end (camera), the camera end only transmits the frames to be displayed according to the playback mode, and when the play end executes fast forward playback, all the frames do not need to be decoded, only the received video frames need to be decoded, and the frames are directly decoded and displayed without special processing. That is, when video stored in the camera is fast-forwarded and played back at different speeds (1X, 2X, 4X, 8X, 16X, etc.), video frames which are not displayed need not be transmitted and decoded, and only the video frames which need to be displayed (fast-forwarded) need to be transmitted and decoded.
In a specific embodiment, when the play requirement indicates to play a still picture, in the transmission process, the I frame, the virtual I frame, and the P frame participating in transmission in the video frame after the initial transmission frame are further determined according to the fast forward speed in the play requirement, and then the I frame, the virtual I frame, and the P frame participating in transmission in the video frame after the initial transmission frame and the initial transmission frame are transmitted to the play end. It should be noted that, the specific rule for determining the I frame, the virtual I frame, and the P frame participating in transmission in the video frame after the initial transmission frame according to the fast forward speed in the play requirement is as follows: when the playing speed is 1 time, transmitting all video frames subsequent to the initial transmission frame; for other playing speeds except 1 time of playing speed, the P frame is not transmitted, and only the I frame and the virtual I frame are selectively transmitted, namely when the playing speed is 2 times, all the I frames and the virtual I frames subsequent to the initial transmission frame are transmitted; when the playing speed is 4 times, selecting the virtual I frame for transmission for all the I frames and intervals subsequent to the initial transmission frame; when the playing speed is 8 times, transmitting all the I frames subsequent to the initial transmission frame and one virtual I frame in the middle of the I frames; when the playing speed is 16 times, only all the I frames subsequent to the initial transmission frame are transmitted. Of course, the above rule is only an example, and those skilled in the art can set the relevant rule according to the service requirement, and the camera determines the corresponding transmission rule according to the fast forward speed to transmit the subsequent video frame.
In another specific embodiment, when the playing requirement indicates that a still picture is not to be played, the camera head end indexes the corresponding I frame or the corresponding virtual I frame as the initial transmission frame through the playing time point, and then may determine, according to the above rule, the I frame, the virtual I frame, and the P frame that are participating in transmission in the video frame after the initial transmission frame, which is specifically referred to in the foregoing, and this embodiment is not described again. On this basis, since still pictures need to be skipped, the I frame, the virtual I frame, and the P frame participating in transmission need to be further filtered by the picture status in the time point index table to obtain the I frame, the virtual I frame, and the P frame finally participating in transmission. In this embodiment, whether the pictures of the preset number of video frames after the I frame and the virtual I frame participating in transmission change or not may be respectively determined according to the picture states in the time point index table, and if not, the corresponding I frame, the virtual I frame, and the P frame are discarded, so as to obtain the I frame, the virtual I frame, and the P frame finally participating in transmission. And finally transmitting the initial transmission frame, the I frame, the virtual I frame and the P frame which are finally participated in the transmission to the playing end. In this process, the time point index table includes the picture states of the I frame and the video frames before and after the virtual I frame, and whether the number of the continuous still pictures exceeds the preset number is determined according to the still picture state recorded by the time point index table, if so, it is indicated that the picture after the I frame or the virtual I frame is a continuous still picture frame which does not need to be transmitted, that is, a video frame which does not need to be displayed at the playing end, and the video frame which does not need to be displayed can be directly discarded by the camera end. Continuing to index subsequent video frames until a frame with a changed picture state is encountered, determining the video frame to be transmitted, and repeating the steps of respectively judging whether the pictures of the I frame participating in transmission and a preset number of video frames after the virtual I frame are changed according to the picture state in the time point index table, and if not, discarding the corresponding I frame, the virtual I frame and the P frame to obtain the I frame, the virtual I frame and the P frame finally participating in transmission.
As can be seen, in the embodiment of the present application, a target video at a video storage end is encoded by inserting virtual I frames at intervals between P frames corresponding to the I frames to obtain a target video including the I frames, the virtual I frames, and the P frames; then, constructing a corresponding time point index table based on time points of I frames and virtual I frames in the target video; then, acquiring a playing requirement of a playing end for playing back a target video, and searching an I frame or a virtual I frame corresponding to the playing requirement from a time point index table to be used as an initial transmission frame; and finally, transmitting the initial transmission frame and the video frame after the initial transmission frame to the playing end so that the playing end can decode and display the received video frame. According to the video coding method and device, the virtual I frames are inserted between the P frames corresponding to the I frames at intervals to code the target video, and during playback, the video storage end can only transmit the video frames needing to be displayed according to the playing requirement, so that the video network transmission efficiency is improved.
