Nothing like that is implemented in FFmpeg. You need find a proper MXF validation tool. I can't recommend any, but searching the web for 'MXF validator' or 'MXF analyser' returns a lot of hits. > Or is the only way to do it is by debugging/printing of ffmpeg MXF mux > with KLV ,and demux on MXF video with supposed KLV info. That approach might work. Good luck. -- Peter (A907 E02F A6E5 0CD2 34CD 20D2 6760 79C5 AC40 DD6B)
