I have changed the command and it works without waring. ffplay -i ~/Movies/More\ Than\ You\ Know.mp4 -af "pan=stereo|FL<FL+FC+BL+SL|FR<FR+FC+BR+SR" I think online documentation should be fixed. How do you think? https://ffmpeg.org/ffmpeg-filters.html#pan https://trac.ffmpeg.org/wiki/AudioChannelManipulation > Just to make sure: You do know that this is not the > best way to downmix, you are using the pan filter > because you know exactly what you are doing? Well, I have got use pan filter just a result of try and error. https://trac.ffmpeg.org/wiki/AudioChannelManipulation seems to suggest me to use -ac 2 option, but my 5.1ch mp4 does not play full audio with -ac 2 option... Or is there correct way to downmix audio any other? // Miya _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
