#7208: Input channel layout '5 channels (FL+FR+FC+LFE+BL)' is not supported

'''Summary of the bug'''
When using input sources with 1 video stream and 1 audio stream that
contains 5 channels, within a MOV container; FFmpeg assumes the audio
stream has a 5.1 surround channel layout in the following pattern:
"FL+FR+FC+LFE+BL".
This is not a valid 5.1 layout - it is missing channel "BR".
But in reality it is not a 5.1 layout at all. It's just 5 mono channels
contained within 1 audio stream.
'''How to reproduce'''
{{{
ffmpeg -i {input}.mov {output}.mp4
}}}
'''Input must contain'''
- mov container
- video stream
- video track
- audio stream
- audio track (channel 1)
- audio track (channel 2)
- audio track (channel 3)
- audio track (channel 4)
- audio track (channel 5)
'''Command and Error'''
