    Ubuntu Video Tearing - STCK1A8LFC

    PatNarciso

      Using the OEM install of Ubuntu,

      there is visible 'tearing' when playing videos during high-action scenes

      If I had to put a value to amount of tearing, I would say ~2% of the video has visible tearing.

       

      example of commands performed:

      cd ~

      sudo apt-get install mplayer wget

       

       

      wget http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_h264.mov

      mplayer -fs big_buck_bunny_1080p_h264.mov

      rm big_buck_bunny_1080p_h264.mov

       

       

      wget http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_stereo.avi

      mplayer -fs big_buck_bunny_1080p_stereo.avi

      rm big_buck_bunny_1080p_stereo.avi

       

       

      wget http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_stereo.avi

      mplayer -fs big_buck_bunny_720p_stereo.avi

      rm big_buck_bunny_720p_stereo.avi

       

       

      wget http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_surround.avi

      mplayer -fs big_buck_bunny_720p_surround.avi

      rm big_buck_bunny_720p_surround.avi

       

       

      other troubleshooting attempted:

      - bios power settings set to 'performance'.

      - 'cpu_frequency_scaling' set to 'performance' for processors 0-3.

       

      other notes worth mentioning:

      out of the box: vdpau is the first output driver mplayer attempts.

      mplayer complains about libvdpau_i965.so not being found.

      > Failed to open VDPAU backend libvdpau_i965.so: cannot open shared object file: No such file or directory

      > [vdpau] Error when calling vdp_device_create_x11: 1

      mplayer will then default to xv (X11/Xv).

       

      My question to intel is: from an off-the-shelf setup, what must be done to achieve tear-free playback of a video?

       

      In advance, thanks Intel!

          Not sure if this will help in your case, but it did help for me... I noticed the graphics improved after I upgrade the BIOS. There is no more tearing when I watch the video from a browser.

          What version is your BIOS? I was using version 25 and it worked pretty well. Just saw that there is a newer version (27), not sure what are the changes as there is no change log. But you should give it a try.

            Hello PatNarciso,

             

            Even though I am not a Linux expert, I think you should try updating the video player. Another good step is to test another video player such as VLC or banshee for instance.

             

            My best recommendation is to post your question also in the Ubuntu Community for further information:
