Re: [streaming] 0.8.6 transcoding h264 + mosaic and frame rate

well... ok

thanks for this info, but in my mosaic I have only one stream + a fake file
and I'm already on a Bi-Xeon, so I need to get a quad or octo core  
xeon if I want correct stream :-(

I just changed h264 by mp2v and result is perfect
but I prefer h264 because soemetimes during my broadcastings I stream  
powerpoint and h264 is much better for that
In both case, I push at 1 Mbps

regards

Nicolas
