[Libav-user] can ffmpeg support add audio/video stream dynamically

[qw]

Hi,


I have one question about ffmpeg's one key function. If ffmpeg fetch one rtmp stream from one rtmp server and no audio stream is available at the beginning, then ffmpeg only detect video stream without audio stream. However, after several minutes, one audio stream existed in rtmp stream, how ffmpeg to do with the case? Can ffmpeg functions add the new audio stream dynamically, or ffmpeg functions/structures need to be reset?


Thanks!


Regards


Andrew
