[Libav-user] can protocol async support to check/get time delay

[qw]

Hi,


http://www.ffmpeg.org/ffmpeg-protocols.html#async


I have one question about the usage of protocol async in ffmpeg.


As we know, protocol async is to decouple I/O operation from demux thread.


In realtime application, if demux thread is too slow, how can I know how much delay there is? Does protocol async have the function of getting the time delay?


Thanks!


Regards
