That sounds plausible.

Is it possible (and better) to capture something other than 4:2:0 video?
Outfmt=yuy2 needs much more CPU time than default format.

My card supports 
 Format YUYV   (16 bits, 4:2:2 packed, YUYV): Packed YUY2
 Format UYVY   (16 bits, 4:2:2 packed, UYVY): Packed UYVY
 Format YUV422P (16 bits, 4:2:2 planar, Y-Cb-Cr): Planar 422P
 Format YUV420 (12 bits, 4:2:0 planar, Y-Cb-Cr): Planar I420
 [and some rgb formats]

Thanks for help,
   Matthias
