Thanks for all the details. I can reproduce the encoding warning with 4.1, it's gone with relative recent git master (probably fixed by commit c822d70). I can reproduce the error log on decoding. So apparently, ffmpeg cannot decode its own muxing successfully. Or it introduces errors while muxing. This doesn't happen when muxing to mp4 or mpegts (for some reason noticably slower than mp4). We may need to open a bug ticket for this.

I tested the following: $ ffmpeg -i m2641080i30m25.xavc.mxf -qscale 2 -vcodec mpeg4 out.mov The output file plays both audio and video for 3:53 secondes (+/- 0:01). This seems correct to me, no?

Thank you for replying again.
