Bridgman doesn't care about video decoding, so it is at the very bottom of the ATI list. :-( Grarpamp mentioned OTA ATSC which is mpeg2, so XvMC is useful. (And also what I'm looking for.) Supposedly VIA extended XvMC so that it is useful for other codecs. But I haven't found info about which boards openchrome supports, and what features really work. > > Recent GPUs can offload most of the video decode duties, but this > > hasn't been documented and FLOSS code hasn't been implemented yet. > > (Unless you can find something in the Chrome family you like.) > > Not sure about that actually...

Sorry, the "hasn't been documented and FLOSS code hasn't been implemented yet." referred to ATI's UVD/UVD2.

Grarpamp might be talking about something like this: http://www.behardware.com/articles/580-1/the-spyder-2-an-affordable-colorimeter.html So far I haven't seen one of these articles explain what happens "under the hood".
