Hi,
I have made one simple transcoding program by using ffmpeg lib, where several
av transcoding tasks are done in one process and each task corresponds to one
thread.
But some ffmpeg function will report error, and sometimes the multi-thread
version of transcoding program will crash abnormally.
For example, av_guess_format("mp4", NULL, NULL) returns error accidentally with
several concurrent tasks. And transcoding program will crash, when calling
av_interleaved_write_frame ().
does ffmpeg support multi-thread in this case? If not, which ffmpeg functions
should be synchronized by application developer?
Thanks!
Regards
Andrew
