Colorspaces

[olabri]

Do anyone knows about any resources about selection of colorspaces. I have no idea what they are and cannot fins anything informative searching this forum (and others).

I've notices that using YUV2 as output in ffdshow reduces the output fps by at least 50%. Some on the other hand produces no outout at all..,

Which color codes are smart to use for a low cpu system? Do some work better with some graphics cards thatn others?

Thankful for any enlightenment...

Simply put, the less conversions from one color space to another to be done, the less CPU power is required. Hence, if your source is YV12, compress and play the video in YV12 color space. Converting to another color space brings no quality benefits and wastes CPU cycles.

does that mean ffdshow picks the same colorspacve as the movie has, or do i have to use a "tool" to get it for each movie?

Because when i have all spaces enabled in ffdshow, it often automaticly selects yuv2 even if it shows faster with the others.
