Yes, I know. This is the simplest way of showing that there is something strange going on. The aim is to do a channel remap to get a correct channel layout for the R128 filter for eg So the mapping can be different, and could be something like: -filter_complex "[0:0][0:0][0:0][0:0][0:0][0:0][0:0][0:0]amerge=inputs=8,pan=7.1|c0=c0|c1=c2|c2=c1|c3=c4|c4=c5|c5=c6|c6=c7|c7=c3|[mix];[mix]ebur128=peak=true" -f null - Bouke > >> Failed to inject frame into filter network: Invalid argument >> Error while processing the decoded data for stream #0:0 >> Conversion failed! >> _______________________________________________ >> ffmpeg-user mailing list >> ffmpeg-user@ffmpeg.org <mailto:ffmpeg-user@ffmpeg.org> >> https://ffmpeg.org/mailman/listinfo/ffmpeg-user >> <https://ffmpeg.org/mailman/listinfo/ffmpeg-user> >> >> To unsubscribe, visit link above, or email >> ffmpeg-user-requ...@ffmpeg.org <mailto:ffmpeg-user-requ...@ffmpeg.org> with >> subject "unsubscribe". > _______________________________________________ > ffmpeg-user mailing list > ffmpeg-user@ffmpeg.org <mailto:ffmpeg-user@ffmpeg.org> > https://ffmpeg.org/mailman/listinfo/ffmpeg-user > <https://ffmpeg.org/mailman/listinfo/ffmpeg-user> > > To unsubscribe, visit link above, or email > ffmpeg-user-requ...@ffmpeg.org <mailto:ffmpeg-user-requ...@ffmpeg.org> with > subject "unsubscribe". _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
