Hi Michael,
I agreed how we can take the information in the wrapper if it's present. In MXF case it can be done. But in other formats, this information is not necessary present ... The other possibility is to set the duration to -1 to disable print when we can't known exactly the duration. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
