Please do not top-post, but reply below whatever you respond to and remove parts of the previous email you do not respond to. Thanks for the advice. I hope I'm following the format now. There is some information here: https://roundup.ffmpeg.org/roundup/ffmpeg/issue1267 maybe some tools like mp4box, easytag or mediainfo can dump that kind of information - I have no idea. I will look into this now. Thanks again. _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
