H264 and aac data streams The Encapsulation Format of audio and video streams pushed by rtmp is similar to that of FLV. Therefore, we can see that to push h264 and aac live streams to FMS, we need to first send"AVC sequence Header"And"AAC sequence Header", These two pieces of data contain important encoding information. Without them, the decoder cannot be decoded

V_rescale_q is used to calculate the PTS for packet. The return value of Av_rescale_q is a large integer, and the result interval for each calculation is very large.Unlike Avcodec_encode_video, the PTS (Small integer and small interval) that changed Avcodeccontext *avctx.Av_rescale_q (a,b,c) is a function used to adjust the timestamp from one time base to another. Its basic action is to calculate the a*b/c, but this function is still necessary, because the direct calculation will have overflow s
