[Libav-user] questions about indefinite waiting for incoming rtmp stream

[Chen Fisher]

Yes, you should use *interrupt_callback*:

https://www.ffmpeg.org/doxygen/3.0/structAVIOInterruptCB.html

This callback function is called repeatedly when there's a blocking
operation like av_read_frame
Just return 1 if you want to abort any blocking operation
