[FFmpeg-user] FFPLAY build on MSYS crashes when playaing any video
Dear all, I built a custom version of ffmpeg on msys/mingw32. ffmpeg and ffprobe are behaving very well, but ffplay crashes when reading any file with video. It displays the first image of the video and then exits without error messages. Did anyone encountered and solved this issue ? Note: ffplay reads very well audio only files. Thanks. Tiaray. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user

Re: [FFmpeg-user] -threads option has no effect
Hi Thanks for looking into my query. I have a main java program within which I run ffmpeg (using exec). Often there comes a scenario wherein my program needs to create 4+ different instances of ffmpeg program for converting files into different formats. When this happens the cpu gets 'too busy' running the ffmpeg instances which affects the performance of my java program. I think lowering the priority(using nice or start /LOW ) of the ffmpeg process might be a possible strategy to solve this, but would be glad if you can help me point towards a platform independent solution.
