Casparcg 2.3 and youtube

Hi everybody. Is it possible to stream to youtube from casparcg 2.2? I have some issues

I have some problem to stream to Youtube also.
It seems that it’s because CasparCG 2.2 and CasparCG 2.3 have 8 audio channels and Youtube needs only 1 or 2 audio channels.
FFMPEG option -ac 2 doesn’t work.
I’ve tried with Vimlesh’ MediaPlayback tool. It doesn’t work.
Can you help us to find a way to set 2 audio channels to CasparCG 2.3 channel or to set 2 audio channels to stream out to youtube.

Should be doable with the map option I think, but I don’t have any examples right now.

Use code like below. I have updated this in lattest CMp. 999

ADD 1 STREAM rtmp:// -codec:a aac -strict -2  -b:a 128k -ar:a 48000 -b:v 2750k -filter:v format=pix_fmts=yuv422p,scale=1024x576,fps=25 -filter:a pan=stereo|c0=c0|c1=c1 -format flv

Thank you very much for your reactivity.
It works well.
