[MPlayer-users] mplayer + dxr3 stuckup

[Timo J Rinne]

Hi

I've tried out mplayer (cvs 20020410 and 20020408) with Hollywood Plus
MPEG card (0.12 drivers, the newest).  Whenever the stream is
re-encoded by mplayer, everything seems to work OK (e.g. playing
avi-file or forcing -vc mpeg12 on vcd mpeg1 or svcd mpeg2 stream).
With mpeg stream this of course causes significant quality loss.

But when I play a mpeg file using hardware decoding (command:
mplayer -vo dxr3:avcodec -ao oss:/dev/em8300_ma movie.mpg), decoding
starts ok, video and audio both appears on the screen, but witihn 1-3
seconds program gets stuck, video and audio freezes and program
becomes inresponsive.

After pressing control-c, program tells me:

  MPlayer interrupted by signal 2 in module: draw_osd 
  *** free_stream() called ***
  VO: [dxr3] Uninitializing

Sometimes after this, card is so messed up, that it has to be reset by
reloading the microcode.  And as I said earlier, with re-encoding
(command: mplayer -vc mpeg12 -vo dxr3:avcodec -ao oss:/dev/em8300_ma movie.mpg)
stream plays properly.

My current processor setup is as follows:

  processor       : 0
  vendor_id       : GenuineIntel
  cpu family      : 6
  model           : 8

  coma_bug        : no
  fpu             : yes

  bogomips        : 1599.07

Kernel version is 2.4.18 and mplayer is compiled with gcc3.
Distribution is RedHat 7.2.

However, I've tried this also with some other motherboards with same
result.  I've also tested two different revisions of the card (Sigma
Designs and some OEM dvd8300 card).  From the microcode side, I've
tested the one in 0.12 Linux driver package, three different ones in
Sigma's 2.3 driver (the newest) release, three different ones in
Sigma's 1.8 driver release (last in version 1 series) and two that are
in Creative Labs' driver set.  But no dice, always the same
endresult.

I would very much appreciate, if someone could help me out.
