Greetings fellow program(mers). A "situation" occurred the other day where, using (cross compiled) ffmpeg+libx264 with mingw-w64, "--enable-pthreads" and the mingw-w64 pthread library, some oddness would result, like the app would "hang" eating up 100% cpu, seemingly doing nothing useful. I was told to bring it up here, as well.
I attempted to capture stack traces during the time that it was "hung" (though who knows how accurate they are): https://gist.github.com/3125847 Anybody have any clue/idea as to what is going on? It is reproducible using ffmpeg.exe from here: http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-20120706-git-8293a21-win32-static.7z then download this file: http://rogerdpack.t28.net/incoming/sintel.mpg then run like this: $ ffmpeg -y -i sintel.mpg -pass 1 -t 75 -c:v libx264 -an nul.mp4 Hangs/pauses on the console occur sporadically. When compiled using ffmpeg's "win32threads" option instead of pthreads, it never has hangs. Any help appreciated.
