Thanks, I did try videobox, but it was also not really working all too well 
(even though it seems less broken than videocrop). 
I don't think videocrop should be deleted. It should be fixed. It's a simple 
element and it has a brilliant name (I would never have guessed that 
'videobox' actually crops stuff). 
And it does work for pictures with well-formed dimensions (e.g. width and 
height = multiple of 8), just not very well for pictures with odd dimensions. 
Sorry for not making this clearer. 
The GST_VIDEO_I420_FOO macros should probably be fixed to match those that are 
used elsewhere (note the round-up of the strides), and GST_VIDEO_I420_SIZE 
should be used when allocating the new buffer etc. Might whip up a patch over 
the weekend.
