      Yes Curaga you should be right. I think I read this too quick and my 1st focus was that I spent so much time to try to make the interlace mode working that I decided to buy a graphical card.

      If some people are interested here is the info about intel drivers and interlace mode:
      https://bugs.launchpad.net/ubuntu/+s...el/+bug/568533

      As I never add 1080i with the intel I can't really compare the video decoding as now I am in 1080p vs 1280x720 before.

      If I understand there is nothing special to be done today to get a better experience with the evergreen cards than waiting that the drivers provide some GPU capabilities?

      Thanks

        Just make sure you try the various options for GL output (rather than Xv) provided by your player.

          I will give them a try. Should I try also gl2?

          I don't know if opengl can impact vnc sessions are not but I know that if I select gl within mythtv for example I can't see through vnc the screens.

          I ll report what I found for anyone benefit.

          Cheers and thanks Bridgman (is your nickname bc you are doing somehow the bridge between ATI dev and linux users?)

            Yes, IIRC the gl2 options often work better.

            Bridgman is my real name. Not sure of the history, presumably an ancestor either designed bridges, worked on a bridge, or lived under a bridge

              lol I like the last one option, Bridgman.

              My last name means the big table so it s worth

              At least we have a roof and a table ;-)

                I looked at the settings and it shows still stereo under lucid sound settings. I had the same with the Intel HD graphics and now I have still stereo shown with the ATI card.

                I did re install in between.

                Is this normal? I will have to look and test if this is just a display issue.

                Code:
                **** Liste des PLAYBACK périphériques ****
                Home directory /home/xabix not ours.
                carte  0: Intel [HDA Intel], périphérique 0 : ALC889 Analog [ALC889 Analog]

                  So with mplayer here are the results for a H264 file:
                  gl is the best but takes around 85% of one cpu
                  gl((yuv) comes after with 75%
                  gl(quick for ATI) around 75%
                  xv(avivo) is good too.

                  with a DVD CPU is very low 16%

                  I will keep gl for now even if it s not perfect with DVD.

                  Thanks

                    You might want to play with gl sub-options as well. Maybe try something like mplayer -vo gl:yuv=2:rectangle=1..

                    The first option should reduce CPU load by doing YUV-RGB conversion on the GPU rather than the CPU, second option should reduce memory usage by using non-power-of-two textures. Default for both of the sub-options is 0.

                      Thanks Bridman for the info.

                      For everyone info, SMplayer provides a good abstraction layer on top on Mplayer and also provides direct configuration of gl(yuv).

                      FYI here is my SMplayer video config:
                      • Enable post-processing by default (quality set to 6 by default) (not set)
                      • Deinterlace by default to what? (set to none)
                      • Use sw video equalizer (not set)
                      • direct rendering? (not set)
                      • Double buffering? (set)
                      • Draw video using slices? (set)

                      If you think that I should change it plz let me know.

                      Merci

                        Does SMplayer give you control over the sub options I mentioned ? If not you may need to play with an mplayer config file to get them...

                          What would happen when the xvba sdk would be leaked and amdpcom.h/amdxvba.h would be public? Would amd shares lose value? When pcom works why don't allow the use of it? One command can be guessed by the hwdecode demos configure script btw. - the rest was removed.

                            I believe the revised XvBA "lite" SDK (using OpenGL rather than PCOM) should be safe for public release, and it's primarily a matter of getting all the heads nodding in the same direction at the same time. PCOM, not so much, and for obvious reasons I can't go into details about why that is.

                              As pcom seems to be the only working way this would be certainly much more interesting...

                                That's one of the reasons why we haven't released an XvBA version for client PC yet.
