Hi,

how about adding input support for a fast decoding lossless codec ?

Since ffmpeg is already used for some other codecs, I would love
to see support for one of the lossless codecs contained in ffmpeg/lavc.
MPNG would be very high quality with 24-bit colorspace support,
but it's not the fastest one in terms of decoding speed, which would
imply additional resources for decoding during editing.
After playing around with all lossless or nearly lossless codecs, FFV1
seems to be pretty fast. Restricting it to a target colorspace of YV12
can speed up things,too.

Is there any faster decoding lossless codec out there ?
The ffmpeg wavelet based SNOW codec looks promising, too.
But it's still experimental.

What do other people on this list think about lossless codec support in
cinelerra ?
I'm talking about source footage, and not export ...

Toby
