    Phoronix: The Video Acceleration State On Linux GPU Drivers

    For those of you curious about the state of hardware-assisted video playback acceleration on the Linux graphics drivers, here's a brief overview...

    Missing from the article is the "small detail" that VA-API is, of now, the only library to implement an API for video encoding too. So all the big lists in the article are all about video decoding only.

      and VAAPI in G45 hardware is pretty dead and incomplete...

        Why recommend an NVidia GPU for htpc? It's overkill when Intel's on die GPUs have more than enough power to decode any 1080p you're likely to throw at it. I'm using a Clarksdale Core i3 and it works great with xbmc.

          Too much of my collection is blu ray to go Linux. I tried to have a Windows-based HTPC a couple of years ago, but blu ray was even fairly bad on that as it struggled with even simple tasks like fast-forward, rewind and pause -> resume. In the end I gave in and got a dedicated player. I love blu ray, but it's a godawful format for portability and open standards and keeps me from using PCs for HTPC use.

            For my HTPC I am not going to bother with video acceleration and I am just going to use a fairly low-power and cool running Sempron CPU for handling everything. It plays 1080p just fine and it cuts down on most of the hassle of getting the thing setup.

            I also know the feeling kaprikawn, but we just went the opposite - no good open standards, no bluray.

              Agree completely. I've got shelves filled with DVDs, but I am steering clear of Bluray... The format is just way too anti-consumer.

                What other choice is there? BD is the only HD format being sold nowadays.

                I don't think ignoring it is the right way to go. Instead if we all did our part to negate DRM as much as possible we would be better off.. Whether it be coding up solutions or bug testing someone elses solutions. I mean I personally would love to have my entire collection in HD.

                    You should get royalties.

                      Do you mean finding ways to crack the protection?

                      Oh no, I would never do that if it were an option. Never.

                        It is how dvd support on linux came about and it will be how bd support on linux will come about... Except this time it is not going to be a simple 8 line patch that does it. It is going to take talent and those that have the talent need to do it.

                          I think you will find that I was being facetious. On the whole I agree with you, but until I can actually use a Bluray disc in a manner I deem appropriate I am not going to be using them. And it is hardly a necessity for me at the moment.

                            Same boat here, really annoying.

                            As far as bluray movies go, installing libaacs and downloading a KEYDB (put into ~/.config/aacs ) file is all needed to have pretty good playback. mplayer and xbmc play blurays just fine, and as a bonus, the annoying menus don't work! Pop in and play. (oh, and the bluray has to be mounted). It's basic, a bit hands on, but possible.

                              I was under the impression that the new encoding scheme had not even been cracked yet for basic playback. Can you provide us with anymore information with how this was done?
