Merged with a different error message.

I tried to add some information to ticket #3823:
-vcodec mjpeg -pix_fmt yuv422p -f rtp fails because 
it would require encoding in rows of 1 block 
instead of 2.
Other encoders use custom Huffman tables which are 
also not allowed.
I believe there is still a bug with quantisation 
tables that I'll try to fix.
