I'm making program to read and write rtmp av stream. If network is bad, some ffmpeg functions will block indefinitely.

The rtmp application will use the following functions, including avformat_open_input(), avformat_find_stream_info(), avformat_alloc_output_context2(), avio_open(), avformat_write_header(), av_read_frame(), av_interleaved_write_frame(), av_write_trailer(), avformat_close_input(), and avformat_free_context().

The above functions are used in ffmpeg and transcoding binary programs.

Which function has indefinite-block issue? How to avoid indefinite-block issue?
