The applicant finds that the existing streaming media live broadcast system does not support the access of third-party push streaming service, so that the existing system has certain limitation.
In order to solve the above problem, the present application provides a streaming media live broadcasting method capable of receiving a third party push stream, and fig. 1 is a schematic flow diagram of a streaming media live broadcasting method capable of receiving a third party push stream according to an embodiment of the present application, and as shown in fig. 1, the method includes steps S101 to S105.
S101: and acquiring a starting instruction and a stream pushing address sent by a third-party streaming media management server.
As shown in fig. 2, the existing streaming media live system includes a streaming media video server (PVS), a streaming media audio server (PCS), or a streaming media video live server (DCBS), and does not support access to a third party push streaming service.
The method and the system add a third-party streaming media management server (THS) and a third-party streaming media server (THC) on the basis of not changing a streaming media video server (PVS), a streaming media audio server (PCS) or a streaming media video live broadcast server (DCBS) of the original system, process RTMP streaming media and access the original services.
In specific implementation, when a user (an IPAD end) enters a room and starts an RTMP flow pushing tool to push flow, the IPAD end sends information such as the room and a flow pushing address of the user to a THS server, and the THS server starts a THC service after receiving the information and establishes TCP connection with the THC service.
If THS and THC are combined into one service, the delay between the watching pictures of a user and the plug-flow pictures at the plug-flow end is longer and longer after the number of live broadcast rooms is increased, the internal logic of the user is complicated, and the audio and video processing of the user cannot be more efficient. In the application, the THS and the THC use a multi-process structure, one THS service corresponds to a plurality of THC services, and when a user finishes plug flow or exits a room, the THS sends an end packet to the THC to finish the THC service.
S102: and if the stream pushing address is effective, acquiring corresponding stream media data according to the stream pushing address.
After a third-party streaming media server (THC) acquires a starting instruction and a streaming address sent by a third-party streaming media management server, judging whether the streaming address is valid, namely whether a data stream can be acquired through the streaming address, if the specific implementation is carried out, firstly judging whether the rtmp address is correct or whether the rtmp address can be pulled to the data stream, wherein the format of the rtmp address is rtmp:// ip address 1935/room number/, and if the address is correct, acquiring corresponding streaming media data through the streaming address.
S103: and decapsulating the streaming media data to obtain original information and naked stream data, and obtaining a video decoder and an audio decoder.
In specific implementation, a third-party streaming media server (THC) performs decapsulation operation on streaming media data after acquiring the streaming media data, acquires original information and naked stream data, and acquires a video decoder and an audio decoder to prepare for the next track splitting step. For example, the original video format (e.g. h264), bitrate, resolution, etc. are obtained, the original audio format (e.g. aac), sampling rate, bitrate, etc. are obtained, and the split-track parameters of the video stream and the audio stream are obtained.
S104: and performing track splitting on the bare stream data according to the original information to obtain a first video stream and a first audio stream.
In specific implementation, performing a track splitting on the bare stream data according to the original information to obtain a first video stream and a first audio stream, including:
s401: reading the bare stream data to obtain a first video stream and a first audio stream;
s402: and storing the first video stream in a first queue, and storing the first audio stream in a second queue.
In specific implementation, the THC performs split-track processing on the acquired bare stream data when processing audio and video streams, and stores the audio stream and the video stream in two queues respectively, so that the THC has independent operation flows when processing the audio and video streams. In the process, a small part of data packets are discarded, and a certain delay is added, so that the jitter of the video stream is eliminated, and the experience of a user is improved.
S105: and re-encoding the first video stream and the first audio stream to obtain a second video stream and a second audio stream.
The THC also performs operations such as cutting, format conversion, recoding and the like on the split video stream, and performs operations such as resampling, recoding and the like on the audio stream.
Re-encoding the first video stream to obtain a second video stream, comprising:
s501: decoding the first video stream by using the video decoder to obtain original video data;
s502: and recoding the original video data to obtain a second video stream.
Re-encoding the first audio stream to obtain a second audio stream, further comprising:
s503: decoding the first audio stream by using the audio decoder to obtain original audio data;
s504: resampling the original audio data to obtain target audio data;
s505: and recoding the target audio data to obtain a second video stream.
For example, after the video stream data packet is completely read, the video stream data packet is decoded into an original frame (YUV420P), and then the video stream data packet is encoded into an h264 format, the code rate is 1300, and the resolution is unchanged.
The audio data is resampled while decoding the obtained audio data packet, and the original audio is resampled into an original pcm file with the sampling rate of 16000kHz, the sound channel digit of 1 and unchanged code rate. And then re-encoding the original pcm file to position the silk audio, wherein the number of the sound channels is 1, and the sampling rate is 16000.
In specific implementation, operations such as cutting, scaling, format conversion and the like can be performed on the video in the process of operating the video, and resampling operation can be performed on the audio in the process of operating the audio, so that the two processes are not interfered with each other. When the video stream is processed, the video stream data can be re-encoded into video stream data with two resolution sizes so as to adapt to the watching effect of a user when the network condition is not good.
The THS-THC service can efficiently access the RTMP stream to the existing platform, and realizes the characteristics of low delay, smooth picture, clear video and the like of the pictures of a live broadcast end and a stream push end.
A multi-process structure framework is used between the THS-THC services, a multi-thread structure is used inside the THC, and one THS service controls a plurality of THC services, so that the two services have clear modules, the coupling degree is low, and the audio and video processing efficiency is high.
In specific implementation, after re-encoding the first video stream and the first audio stream to obtain a second video stream and a second audio stream, the method further includes:
s106: sending the second video stream to a streaming video server; and sending the second audio stream to a streaming media audio server.
In specific implementation, the THC pushes audio and video streams to the PVS and the PCS through an RTP protocol, the 39 workstation will subscribe to the PVS and the PCS for streaming media processed through the THC service, then the PVS and the PCS will push respective audio and video streams to the DCBS, finally the DCBS pushes the streaming media to the live broadcast end, and finally all users in the same room or users watching the live broadcast end can see the streaming media picture of the push stream end.
