[gst-devel] caps negotiantion again

[Emmanuel Raulo]

Hello
AFAIK, the "raw" format in ffmpeg is YUV 420 planar, which means that 
you successively get the whole Y plane in full resolution followed by 
the U plane in half resolution and V plane in half resolution too, all 8 
bits per pixel.
I'm not sure what are the corresponding GStreamer formats though.
Cheers
