Hello

I know how to select an language by language name:

-map 0:m:language:fra

like

ffmpeg -i input.ts -map 0:v -map 0:m:language:fra  -codec copy output.mp4

i know to avoid an error if the language don't exist.

ffmpeg -i input.ts -map 0:v -map 0:m:language:fra?  -codec copy output.mp4

This leads to no audio if the language is missing.

But very cool would be to have an fallback language or fallback to the
default behavior (auto select language).


Is it possible or need we a patch?


regards

Patrick
