[MPlayer-users] mplayer SVN plays video too fast on FreeBSD

[Tom Evans]

Hi all

Nvidia recently released a video driver for FreeBSD 8/amd64 (which was
previously unsupported by nvidia). With this, amd64 users finally got
access to libvdpau.

As such, I wanted to recompile mplayer with support for vdpau.
Unfortunately, the packaged version of mplayer in freebsd is
'mplayer-0.99.11_14' (which comes from MPlayer-1.0rc2.tar.bz2), which
doesn't know about vdpau, so I set about to compile from tip of svn.

So, I checked out mplayer trunk, r29977, and made a few changes to
support compilation on FreeBSD (see attached diff). The program built
and compiled successfully, but every file I play through it has the
video processed way too fast.

It almost looks as though it is trying to benchmark the video by
playing it as fast as possible. A 40 minute TV episode only takes
about 3 minutes to play through! The audio playback was correct, no
distortions.

My configure line for mplayer was:

--enable-png --enable-menu --disable-tv-v4l1 --disable-tv-v4l2 \
--disable-dvdnav --disable-ssse3 --disable-directfb --disable-faac \
--disable-twolame --disable-mencoder --disable-mad --disable-libdv \
--disable-theora --disable-musepack --enable-libdca --enable-speex \
--disable-xanim --disable-live --disable-xmms --disable-jack --disable-nas \
--disable-openal --disable-smb --disable-fribidi --disable-cdparanoia \
--disable-libcdio --disable-ladspa --disable-liblzo
--enable-runtime-cpudetection \
--disable-win32dll --disable-qtx --enable-real
--realcodecsdir=/usr/local/lib/win32 \
--enable-gui --extra-cflags="-I/usr/local/include/freetype2
-I/usr/local/include" \
--enable-freetype --disable-rtc --disable-arts --disable-caca --disable-lirc \
--disable-sdl --disable-svga --disable-aa --disable-esd \
--disable-joystick --extra-libs="-L/usr/local/lib -ldca" \
--prefix=/usr/local --mandir=/usr/local/man --target=amd64-srcbld-freebsd8.0 \
--enable-vdpau

My ~/.mplayer/config looks like:

vo=vdpau,xv
#vo=xv
vc=ffh264vdpau,ffvc1vdpau,ffmpeg12vdpau,ffwmv3vdpau,
cache=65536
fs=1
afm=hwac3

The effect is noticed with vo=vdpau,xv or with vo=xv and vc commented
out. It didn't appear to matter what video was being played, I tried
mkv/x264, avi/xvid and mpeg2/mpeg2ts.

Any ideas?

Cheers

Tom
