[MPlayer-users] Smooth DVD Playback And OpenGL

[Jason Van Cleve]

To play a DVD.  This is all I really want from Linux--my one desire.
I've looked high and low for a suitable player, and Mplayer certainly
looks the most appealing to me (I like that it's GUI-independent and can
run in text mode).  But DVD playback (only DVDs, not AVIs) is a little
jerky with Mplayer (0.90pre4, built from source), just enough to be
irritating.  Audio output is fine (oss), but there is a very slight
pause in the video about every 1/3 second.  This seems to be an Mplayer
flaw, because I have a fast, up-to-date system, and other DVD players
work better.  Xine performs best for DVDs--nice and smooth using
dvd-nav; but Xine is not what it's cracked up to be (it can't even play
an MP3 on my system without hiccuping every so often), so I would much
rather use Mplayer.  DVD playback is also better in Ogle, though it's
not as good as Xine, and let's face it, Ogle's interface is a shoddy
piece of crud.  (All right, just an opinion. . . .)

So I'm really hoping someone will help me get Mplayer working well,
because on the whole, I think it really kicks ass.  Or at least, let me
know whether I should report a bug or post to the advanced user list.
I've read all the doc's thoroughly, google'd 'till my brain hurt, tried
all the options I could find in the man page (-framedrop, -cache,
-double, -nosound, etc.), I have DMA enabled on my drive, and I've tried
all the latest dvdread (0.9.1, 0.9.2 and 0.9.3) and dvdcss (1.2.0 and
0.0.3ogle3) packages as well as uninstalling those and using
libmpdvdkit:  the result is always the same, slightly jerky video for
DVDs.  AVIs play fine--a little out of sync, but I can adjust that.

Which brings me to my other problem.  All of the above pertains to the
xv driver.  I thought maybe I could get better results with one of the
gl options (which were compiled), but Mplayer crashes when I use those.
I've included some output below along with my system spec's.  With gl I
get a half second of sound, then it hangs for several seconds and
finally crashes.  With gl2 I get a little piece of sound and then it
crashes immediately.  You'll note from my spec's that I have a GeForce2
(GTS) card.  I know the doc's say Mplayer is "known not to work" with
it, and I know how you feel in general about Nvidia and their drivers. I
tend to agree, but this is my card, it's a popular card, and it does
well most of the time, so my wish is for someone to actually try and
resolve this here.  It ALMOST works, and I have a good system for
testing this, fast hardware, and a newly installed LFS OS with the
latest software (or the sanest:  gcc 2.95.3 and automake 1.5).  I have
the latest Nvidia drivers installed, 1.0.2960, with Nvidia's headers
linked in /usr/X11R6/include/GL/, but I've also tried using the utah-glx
driver with MesaLib 3.2, and that didn't help.  Neither did SDL.  The GL
modules just won't go.  Perhaps Mplayer is using some advanced GL
feature that my card is choking on, or perhaps this is a bug in Mplayer.

I've spent much time on this and tried many things, for it is my one
desire.  If I could get smooth DVD video with Xv, I won't cry about the
gl bug; but maybe GL is my key, and I just need a workaround or a
patch.  Maybe Xine is using GLX successfully, and that's why it plays
smoothly.  I dunno.  Here are my hardware spec's:

        MSI K7T Turbo2 mainboard
	AMD Thunderbird 1.4GHz
	half-gig' of PC133 cas2 SDRAM
	ASUS v7700 GTS 32-meg GeForce2
        3 Western Digital HDs
        1 DVD-ROM, "OEM316B" (secondary slave)
	SoundBlaster Live! Platinum (with LiveDrive)

Software:

        LFS 3.3
        kernel 2.4.18
        libc 2.2.5
        XFree86 4.2.0
        gcc 2.95.3
        ld 2.12
        as 2.12
        Nvidia drivers 1.0.2960
        ALSA 0.9.0rc1

Here's some verbose output from when I use -vo gl:

MPlayer interrupted by signal 11 in module: uninit_vo 
- MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. For details, see DOCS/bugreports.html section 5.b.
- MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/bugreports.html and follow instructions there. We can't and won't help unless you provide these informations when reporting a possible bug.

. . . Sorry if this is the wrong place to be posting all this info'.  If
so, just let me know if I should report this as a bug, or what?

Thanx very much,
