[FFmpeg-user] to make ffv1 from uncompressed 10 bit avi ( decklink capture )

[Jim Shupert]

friends,

I have a ubuntu 10.04 64 bit machine  with a blackmagic decklink card
I am capturing a 10 bit uncompressed avi [ v210 ] using mediaexpress.
that i wish to transcode into several things - one being a ffv1 file w pcm audio.

i get an error of
*Error while opening encoder for output stream #0.0 - maybe incorrect
parameters such as bit_rate, rate, width or height*

below please find the ffmpeg command   and then some mediainfo details on the source file.

Maybe i need to tell ffmpeg something about the input file ( 005-10bit.avi )

I would be grateful for any good advice .

Thanks
