      2.3.1.17 DXR3/Hollywood+

      MPlayer supports hardware accelerated playback with the Creative DXR3 - and Sigma Designs Hollywood Plus cards.

      + and Sigma Designs Hollywood Plus cards. These cards both use the em8300 MPEG + decoder chip from Sigma Designs.

      First of all you will need properly installed DXR3/H+ drivers, version 0.12.0 or later. You can find the drivers and installation instructions at the DXR3 & Hollywood Plus for Linux site. Configure should detect your card automatically, compilation - should go without any problems.

      + should go without problems.

      Usage:

      -
      -vo dxr3:<noprebuf>:<codec>:<device>
      -
      Where <noprebuf> specifies turning off prebuffering. - This is done automatically on Athlons. If playback is out of sync try - disabling prebuffering. If noprebuf is left out prebuffering is enabled - (except on Athlons). -
      - <codec> = fame/avcodec, avcodec produces better quality - output, but fame is faster for those of you with slow machines. The default is - to use libavcodec. Note that you need libavcodec properly installed (read - DOCS/codecs.html). -
      +
      -vo dxr3:noprebuf:<device>
      +
      noprebuf turns off prebuffering. Prebuffering is a feature + of the em8300 chip that enables it to hold more than one frame of video at + a time. This means that when you are running with prebuffering (default) + MPlayer will try to keep the video buffer filled with data at all + times. If you are on a slow machine MPlayer will probably use close + to, or precisely 100% of CPU. This is especially common if you play pure MPEG + streams (like DVDs, SVCDs a.s.o.) since MPlayer will not have to + reencode it to MPEG it will fill the buffer very fast.
      + With prebuffering video playback is much less sensitive to other + programs hogging the CPU, it will not drop frames unless applications hog + the CPU for a long time.
      + Prebuffering does not work on all machines (especially Athlons where it is + turned off automatically). If you experience problems with video/audio sync + use noprebuf. When running without prebuffering the em8300 is + much more sensitive to CPU load, so it is highly suggested that you turn on + MPlayer's -framedrop option to avoid further loss of + sync.
      <device> = device number to use if you have more than one em8300 card.
      Any of these options may be left out, but they must be specified in this - order, i.e. dxr3:fame works, dxr3:1 works, but - dxr3:1:avcodec will not.

      If sample rate is below 44100Hz, select either 44100Hz or 48000Hz - depending on which one matches closest. I.e. if the movie uses 22050Hz use - 44100Hz as 44100 / 2 = 22050, if it is 24000Hz use 48000Hz as 48000 / 2 = 24000 - and so on. This does not work with digital audio output - (-ac hwac3).

      The em8300 cannot play back samplerates lower than 44100Hz. If the sample + rate is below 44100Hz select either 44100Hz or 48000Hz depending on which + one matches closest.

      -vop lavc/fame
      +
      To watch non-MPEG content on the em8300 (i.e. DivX or RealVideo) you have + to specify an MPEG1 video filter such as libavcodec (lavc) or libfame + (fame). At the moment lavc is both faster and gives better image quality, it + is suggested that you use that unless you have problems with it. See the man + page for further info about -vop lavc/fame.
