Hi James,
As you have seen, the traffic is slow now.
I'm not able to reproduce it. I run into issues with the both (transcode &
ffmpeg).
See below :
olivier@fondcombe:~/Vidéos$ transcode -x v4l2 -i /dev/video0 -p /dev/dsp0
-Q 5 -w 1000 -y ffmpeg,tcaud -F mpeg4 -J smartyuv,pv=fullscreen -o file.avi
[transcode] critical: Invalid filename "/dev/dsp0": No such file or
directory
olivier@fondcombe:~/Vidéos$ ffmpeg -f pulse -i default -f v4l2 -i
/dev/video0 -vtag divx -s svga -q:v 5 file.avi -s svga -f rawvideo - |
ffplay -i - -s svga

That's me but It seems me that you don't have specified the number for dsp
device.
My configuration is the following.
version transcode : 1.17-1
os : Linux Mint 15
What is your configuration ? your device (a webcam ? )
Could you put the output from the terminal.
Thanks.
Regards.
