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
