More info When I record with the above command, I don't get any warning/error message at the time of recording. When I run the following command on the generated file ./ffmpeg -i /Store3/Test/filename.mkv -f null /dev/null I get a lot of red messages Application provided invalid, non monotonically increasing dts to muxer in stream 0: If I remove the last output option: -vsync passthrough When I record I get a lot of warning messages Past duration 0.646019 too large and Cliping frame in rate conversion by 0.523094 When I run the following command on this file ./ffmpeg -i /Store3/Test/filename.mkv -f null /dev/null I get NO error message at all What does the mean? _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
