the thing that took a bit of time to keep from getting confused is audio mapping. streams are indexed from 0 while channels are indexed from 1. knowing when something needs the stream index vs the channel index gets weird until that one day it finally clicks. i also argue with its choices of channel layout names[0]. a lack of 5.1+2.0 to be labeled similar to L,R,C,LFE,Ls,Rs+Lt,Rt. instead, it wants to call it some 7.1 monstrosity. also, industry standard for 5.1 is L,R,C,LFE,Ls,Rs while FFMPEG calls it FL,FR,FC,LFE,BL,BR. They also forgo Lt/Rt for DL/DR. Maybe I'm too video centric, and these make more sense to an audio centric person??? [0]https://trac.ffmpeg.org/wiki/AudioChannelManipulation#Listch... |
