[MEncoder-users] V210 10-bit 422 Output

[Larry Reznick]

I have v210-encoded video. I'm trying to get 10-bit YUV422P out of it. I 
can get 8-bit 422p if I use the "-vf yuy2" option. If I don't use a -vf 
option at all, I get 32-bit RGBA output, but v210, used by the AJA 
board, delivers 10-bit, as the codec's identifier points out. Here's a 
sample output:

---8<---

The size of the frames (1/100th of the byte size reported in the last 
line) corresponds with 32-bit RGB size. MPlayer can play that output 
file, but it's not the 10-bit 422p I was hoping for. I can't see any way 
to deliver 10-bit frames in the documentation. Can you suggest what I'm 
overlooking or is 10-bit YUV422P not supported as MEncoder output? 
Thanks for any help you can give me.
