Thanks, I already tried this, but it's the same.
The error says:
 > Size 153600 is not a multiple of unit
 > > size 230400

In my case the video is 320*240 = 76800, so the size for UYVY should be, 
76800 * 2 = 153600. However, the error says it should be 230400 = 76800 
* 3, but thats not true.
I get some recorded data if I set the size to 230400, but then the video 
is not correct, because it UYVY should be 2 bytes per pixes and not 3.

And what makes me wondering even more: if I don't specify the BIG_ENDIAN 
in the RGBA/RGB format, UVUY recording is working with the same video 
(although I don't have something to do with RGBA/RGB in this case at all).
