[FFmpeg-user] Fwd: "Guessed Channel Layout for Input Stream" - how to assign channels? (FL+FR+FC+LFE+BL+BR)

[Steve C]

> Please try:
> $ ffmpeg.exe -channel_layout FL -i 01_5.1.FM.L.wav
> -channel_layout FR -i 02_5.1.FM.R.wav -channel_layout FC
> -i 03_5.1.FM.C.wav -channel_layout LFE -i 04_5.1.FM.LFE.wav

okay, that seems to work!
thanks for the help!!

I had tried something similar, but was putting the -channel_layout
option after the input for each audio channel.
putting the -channel_layout option before the input obviously makes
all the difference.

the output file that is created works with Quicktime 7 and can be
imported into Final Cut Pro (although FCP gives a warning that the
file is not optimized).

the only issue i see with the output file is that Quicktime 7, by
default activates only the first audio stream,
all other audio streams are turned off, and have to be enabled
manually through the Quicktime movie properties.

not sure why this would happen - here is a screen shot of the
Quicktime Movie properties to
illustrate what I'm describing:

I don't know if there is anything that can be done through FFMPEG to
change this, seems like an issue with Quicktime?


also, FYI here is the FFMPEG statement that worked for me:

ffmpeg -i /Test-Files-02/035925_NTSC_ProResHQ_NA.mov -channel_layout
FL -i /Test-Files-02/5.1.FM.L.wav -channel_layout FR -i
