[FFmpeg-user] maping, using two inputs

[Boštjan Strojan]

This

ffmpeg -i audio.m4a -i videowithaudio.mov -pix_fmt yuv420p -acodec
copy $optionsCRF "out.mp4"

seems to do what i want: ignores the audio in videowithaudio.mov and
just uses the preencoded audio.m4a. Should i assume that this will
work in the near future as well, how about if the videowithaudio.mov
would have more than 2 audio channels? What is the uber-correct
command line?

thanks,

b.
