[FFmpeg-user] amid fails when there are more than 8 input channels (in one file)

[Bouke / VideoToolShed]

Hi all,
Strange thing, more than 8 channels give silent output:

ffmpeg -i 9Ch_orMore.WAV -filter_complex "[0:0][0:0] amix=inputs=2,pan=mono|c0=c0+c1” -ac 1 mono.wav

gives on errors whatsoever, but output is silent.

Is this a bug or user error?

thx

Bouke
