In an embodiment, the historical surveillance video stream may be video data obtained by processing the real-time surveillance video stream after the real-time surveillance video stream is obtained, for example, after the transcoding server obtains a data packet from the media server, the data packet is processed to obtain a video stream in an H264 (mpeg-4 tenth part, mpeg refers to Motion Picture Experts Group-4) format, and then the video stream in the H264 format is stored in the storage server, so that when the video stream needs to be called or viewed, the transcoding server obtains the video stream from the storage server.
202: and acquiring a video stream corresponding to the video playing request according to the video playing request.
In an embodiment, after the transcoding server receives a video playing request sent by a web page, the transcoding server obtains a video stream according to the video playing request, for example, if the content of the video playing request is a real-time monitoring video requesting a front-end camera in a certain area or a certain specific location, the transcoding server may obtain a data packet sent by a media server, and then process the data packet to obtain a video stream, or if the content of the video playing request is historical monitoring video data, the transcoding server may obtain the video stream by sending a data obtaining request to a storage server.
In one embodiment, when the webpage end sends a video playing request to the transcoding server, the webpage end needs to carry the identifier of the transcoding server first, so that the transcoding server needing to be requested can be determined, and at the same time, the video playing request needs to carry the webpage identifier of the webpage end, so that the transcoding server can determine the webpage end sending the request, correspondingly determine whether the webpage end has the right to access, and subsequently return the data corresponding to the request, so that the webpage end can view the video data, and at the same time, the video playing request needs to carry the data identifier, so that the transcoding server can obtain the video stream corresponding to the data identifier, and in the video playing request, the size of the data content can be carried, so that the transcoding server can allocate the memory to perform corresponding processing according to the size of the data.
203: and acquiring a video frame in the video stream according to the video stream, and judging whether the video frame in the video stream is a key frame.
In an embodiment, after the transcoding server acquires the video stream, the transcoding server receives a video frame in the video stream, as shown in fig. 3, where the video frame includes a key frame 31 and a non-key frame 32, and it is necessary to determine that the video frame is the key frame, so that the web page end can initialize according to the key frame to play video data correspondingly.
In an embodiment, before a video frame is obtained, each key frame and non-key frame in the video frame need to be sequenced according to a time sequence, so that in the received video frame, the key frame and the non-key frame can be combined according to the time sequence to form a complete picture without searching a corresponding non-key frame for each key frame.
In one embodiment, when it is determined that the video stream is not a key frame, the video frame needs to be deleted, which means that the video frame belongs to a non-key frame, and there is no corresponding key frame, and the video frame cannot be played normally, the video frame needs to be deleted, and this step includes: and when the video frame is not the key frame, deleting the video frame and judging whether the next video frame is the key frame.
204: when the video frame is a key frame, an initial data packet is determined according to the key frame, and the initial data packet is sent to the webpage end, so that the webpage end initializes the player.
In an embodiment, when a video frame is a key frame, the key frame may be processed to obtain an initial data packet, so that the web page end initializes the player, and the corresponding web page end can play subsequent video data after initialization.
205: and after the key frame is sent to the webpage end, judging whether the next video frame is the key frame.
In one embodiment, an initial data packet is sent to a webpage end at a transcoding server, so that the webpage end can directly play video data after the webpage end initializes a player, at the moment, the video data needs to be packaged so that the video data received by the webpage end can be directly played, each complete picture in the video frames has a key frame and a non-key frame, when the transcoding server extracts the video frames, the video frames are sequentially arranged according to a sequence, a serialized video packet group is obtained, when the webpage end can play the serialized video packet group, a component of the serialized video packet group needs to be determined, as the video frames are sequentially arranged, a non-key frame with a key frame positioned behind the key frame is searched, the serialized video packet group can be obtained, when whether the non-key frame is obtained or not is judged, whether the next video frame is the key frame or not can be judged, thereby making it possible to determine the composition of the serialized video packet group by making a decision on the next video frame.
206: and when the next video frame is not the key frame, caching the non-key frame into a cache queue, and after finding out the next key frame, packaging the previous key frame and the non-key frame to obtain a serialized video packet group.
In an embodiment, when the player is initialized at the web page, and the web page can directly play video data, and whether the next video frame is a key frame or a non-key frame is determined, the situation that the next video frame is a key frame or a non-key frame occurs.
In one embodiment, when a serialized video packet group is obtained by encapsulating key frames and non-key frames, the non-key frames may be buffered in a buffer queue according to a time sequence, so that when the key frames and the non-key frames are encapsulated to form the serialized video packet group, the non-key frames can be directly extracted from the buffer queue according to the sequence of the non-key frames, and thus the key frames and the non-key frames can be directly encapsulated to obtain the serialized video packet group, which includes: when the next video frame is not a key frame, sequentially caching the non-key frames to a cache queue according to the time sequence; after the next key frame is found, the previous key frame is obtained, and non-key frames positioned between adjacent key frames are obtained from a buffer queue; obtaining a serialized video packet group according to the previous key frame and the non-key frame positioned between the adjacent key frames; specifically, as shown in fig. 4, an I frame 401 is used as a key frame, a P frame 402 is used as a non-key frame, the I frame 401 located at the uppermost side is sent to a web page end, so that after the player is initialized at the web page end, a next key frame is searched, for example, the next video frame is used as the P frame 402, the P frame 402 is cached in a cache queue 403, as shown in fig. 4, when the P frame 402 is cached in the cache queue 403, the P frame 402 is cached according to a time sequence, so that the non-key frame can be directly extracted from the cache queue when a serialized video packet group is formed by using the key frame and the non-key frame, thereby avoiding that the video frames need to be sorted again after the key frame and the non-key frame are obtained, and when the key frame and the non-key frame are obtained, the non-key frame located between two adjacent key frames and the previous key frame form a serialized video packet group, thereby sequentially obtaining each serialized video packet group, and playing the video.
In an embodiment, after finding the next key frame, the previous key frame and the corresponding non-key frame may be directly encapsulated into a serialized video packet group, and then the serialized video packet group is directly sent to the web page end, or after a plurality of serialized video packet groups are formed by encapsulation, the serialized video packet group is sequentially sent to the web page end, in this process, when the non-key frame corresponding to each serialized video packet group is cached, the non-key frame of the next serialized video packet group may be cached after the non-key frame of the previous serialized video packet group is extracted, or the non-key frames of different serialized video packet groups may be cached by using different cache queues, so that the key frame and the corresponding non-key frame can be correspondingly encapsulated, and the problem of encapsulation error caused by non-correspondence of the key frame and the non-key frame is avoided.
207: and correcting the decoding time of the serialized video packet group according to the serialized video packet group and the video playing request of the webpage end, and sending the corrected serialized video packet group to the corresponding webpage end so that the player plays the video.
In an embodiment, after the serialized video packet groups are obtained, the video playing time of each webpage end is determined according to the video playing request of each webpage end, so that the decoding time of each serialized video packet group can be corrected, and each webpage end can watch corresponding video data at corresponding time. In an embodiment, when a video playing request sent by a web page is received, a corresponding websocket port may be allocated to each web page, so that each web page communicates with the corresponding websocket port, and thus, during communication, data is prevented from being disordered, which includes: distributing a corresponding websocket port for the webpage end according to the video playing request; detecting the websocket port, and after receiving a video playing request, adding a webpage end corresponding to the video playing request to a forwarding list corresponding to the websocket; and correcting the decoding time of the serialized video packet group according to the serialized video packet group and the video playing request, and sending the corrected serialized video packet group to a corresponding webpage end in a forwarding list.
In an embodiment, after receiving a video playing request from a web page, the web page in a forwarding list of the transcoding server has a corresponding timestamp, so that in a sending process of a serialized video packet group, a decoding time corresponding to the serialized video packet group is adjusted according to the timestamp. In an embodiment, when sending a modified serialized video packet group to a web page, a web page that needs to send the serialized video packet group needs to be determined first, at this time, a websocket port may be set on a transcoding server, so that the web page can only communicate through the websocket port, and then the websocket port is detected, when there is a request for sending the web page, the web page is added to a forwarding list, so that after video data is encapsulated, the serialized video packet group is sent to a corresponding web page in the forwarding list, where the step includes: setting a websocket port; detecting the websocket port, and adding a webpage end corresponding to a video playing request to a forwarding list after the websocket port receives the video playing request; correcting the decoding time of the serialized video packet group according to the serialized video packet group and the video playing request, and sending the corrected serialized video packet group to a corresponding webpage end in a forwarding list; specifically, when sending the serialized video packet groups to a plurality of web page terminals, the serialized video packet groups may be sent in sequence according to the order of the video playing request of each web page terminal, or the corresponding serialized video packet groups may be sent to a plurality of web page terminals at the same time. In one embodiment, when sending a serialized video packet group to a web page, in order to avoid that video data in a transcoding server is changed, the serialized video packet group is copied and sent to a play queue corresponding to each web page, thereby retaining video data of the web page, and enabling each web page to play corresponding video data according to the corresponding play queue, and when sending the serialized video packet group to each web page, sequencing according to a time sequence of the serialized video packet group, sending the serialized video packet group to each web page in sequence, and correcting decoding time of each serialized video packet group, so that each web page can receive the corresponding serialized video packet group, and playing time of the serialized video packet group of each web page is accurate, the method includes: acquiring the picture time of the serialized video packet group according to the serialized video packet group; according to the picture time of the serialized video packet group, caching the serialized video packet group to a sending queue according to the time sequence; according to the sequence of the serialized video packet groups in the sending queue and the video playing request of the webpage end, sequentially copying the corresponding serialized video packet groups from the sending queue, correcting the decoding time of the serialized video packet groups to obtain corrected serialized video packet groups, and caching the corrected serialized video packet groups into the corresponding playing queue; specifically, as shown in fig. 5, it is assumed that when the serialized video packet group one 511, the serialized video packet group two 512, and the serialized video packet groups three 513 and … are sequentially buffered to the sending queue 51 according to the screen time of the serialized video packet group, when a plurality of web sites send video playing requests, the serialized video packet group one 511, the serialized video packet group two 512, and the serialized video packet group three 513 are sequentially copied, and then corresponding serialized video packet groups are sequentially sent to the playing queue one 521, the playing queue two 522, and the playing queue three 523, and the decoding time of the serialized video packet groups is modified, so that the corresponding web sites can play videos at corresponding times.
In one embodiment, when the corresponding serialized video packet group is copied from the transmission queue, the serialized video packet groups at the head positions in the transmission queue are sequentially copied and distributed, so that each serialized video packet group can be copied and distributed, omission of the serialized video packet groups is avoided, the serialized video packet groups sent to the webpage end are complete, and the webpage end can normally play pictures.
It should be noted that the picture time refers to the time of each serialized video packet group in the same video, for example, a certain video includes 10 serialized video packet groups, and 10 serialized video packet groups have corresponding playing time, so that the playing time can be used as the picture time of the serialized video packet groups, or the picture time is given to the serialized video packet groups according to the playing sequence of the serialized video packet groups, so that the serialized video packet groups can be arranged according to the time sequence, and thus, when the serialized video packet groups are sequentially sent to a web page, the problem of missing the serialized video packet groups does not occur.
In one embodiment, when obtaining the serialized video packet group in the transmission queue and needing to transmit the serialized video packet group to the corresponding web page, the decoding time corresponding to each web page needs to be determined, and the target decoding time corresponding to each web page can be determined according to the playing time of each web page and the decoding time of the serialized video packet group, so that the decoding time of the serialized video packet group can be corrected and then transmitted to the corresponding web page, and the method includes the following steps: acquiring playing time corresponding to the webpage end according to the video playing request of the webpage end; acquiring the decoding time of the serialized video packet group; correcting the decoding time of the serialized video packet group according to the decoding time of the serialized video packet group and the playing time corresponding to the webpage end to obtain the target decoding time of the serialized video packet group corresponding to the video playing request; correcting the decoding time of the serialized video packet group according to the target decoding time of the serialized video packet group, and sending the corrected serialized video packet group to a corresponding webpage end so that the player can play videos; specifically, for example, after the playing time of a certain web page end is 0 second, the decoding time of the serialized video packet group is 0 second, and the time length of the serialized video packet group required to be decoded is 10 seconds, the target decoding time is 10 seconds, so that the web page end can play video data at the corresponding time.
In an embodiment, when the transcoding server sends data to the webpage end, if disconnection or other abnormal states of the webpage end occur, the data cannot be sent to the webpage end, so that data accumulation occurs in the transcoding server, a preset data volume can be set at the moment, whether data accumulation occurs in the transcoding server is judged through the preset data volume, when the data accumulation occurs, connection between the webpage end and the transcoding server is disconnected, threads are recycled, and the phenomenon that the data accumulation occupies resources of the transcoding server is avoided.
It should be noted that the decoding time refers to the playing time of each serialized video packet group that already includes the serialized video packet group when being formed, the playing time is the decoding time of the serialized video packet group, and when different web page ends are watched, if a first web page end starts watching in 0 second and a second web page end starts watching in 10 second, the decoding time corresponding to the first web page end is 10 seconds and the decoding time corresponding to the second web page end is 0 second, so that the same serialized video packet group can be sent to different web page ends only by modifying the decoding time of the serialized video packet group.
In one embodiment, when sending the serialized video packet group to the web page, a socket handle is used for sending data, but in the process, a situation that data is not sent completely occurs, at this time, a data sending position in a sending queue can be recorded, and when sending data next time, the unsent serialized video packet group can be sent continuously according to the data sending position, and the step includes: detecting the connection state of a webpage end and the data sending state in the sending queue, and judging whether the sending of the serialized video packet group in the sending queue is finished; when the sending of the serialized video packet group in the play queue is not finished, recording the data sending position in the sending queue; and according to the data sending position, when the webpage end is reconnected, the serialized video packet group is continuously sent.
In one embodiment, when processing video frames, the video frames may be encapsulated by an encapsulation thread, and then the encapsulation thread may communicate with a sending thread by using a transmission signal, so that the sending thread may send the serialized video packet group to the web page side, and this step includes: acquiring thread representations of encapsulation threads encapsulating key frames and non-key frames, detecting the encapsulation state of the encapsulation threads, and judging whether the serialized video packet group is encapsulated; acquiring a thread identifier of a sending thread for sending the corrected serialized video packet group; after the serialized video packet group is packaged, acquiring a corresponding transmission signal according to the thread identifier of the packaging thread and the thread identifier of the sending thread; transmitting a transmission signal to the transmission thread, correcting the decoding time of the serialized video packet group according to the transmission signal, and transmitting the corrected serialized video packet group to a corresponding webpage end so that the player plays a video; specifically, the encapsulation thread and the sending thread are responsible for corresponding content, the encapsulation thread is responsible for encapsulating key frames and non-key frames, the sending thread is responsible for sending encapsulated serialized video packet groups, and the encapsulation thread and the sending thread communicate through transmission signals, so that cross use between the encapsulation thread and the sending thread is avoided, and sending of the serialized video packet groups is achieved through interaction of the transmission signals.
The embodiment of the application provides a video stream management method for realizing plug-in-free playing of a webpage end, which is characterized in that the webpage end is communicated with a transcoding server, the transcoding server packages the video frames and sends the video frames to the webpage end, the webpage end can directly play video data without plug-in playing, one transcoding server can correspond to a plurality of webpage ends, therefore, when the video data is sent to the webpage end, the video data can be sent to different webpage ends only by changing the decoding time of the serialized video packet group without corresponding transcoding servers for each webpage end, and each transcoding server packages the corresponding serialized video packet group for each webpage end, thereby reducing resource consumption, and the encapsulation thread and the sending thread work independently through signal interaction, so that the thread is prevented from being disordered, and the video data is stably transmitted.
