|
Please contact me if you experienced any of the above problems. We need
|
|
|
|
|
people to test fixes and send us as many system details information as
|
|
|
|
|
possible (kernel+libc+gcc+binutils version, test results, /proc/cpuinfo etc)
|
2001-04-30 22:58:22 +00:00
|
|
|
because these are system-dependent problems and aren't reproducable here.
|
|
|
|
|
Please tell me if you can fix them or you are only a user.
|
2001-04-30 02:16:07 +00:00
|
|
|
Unfortunately we can't reproduce these here, so it's very hard to fix.

Various A-V sync and other audio problems:
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
General audio delay or jerky sound (exists with all or many files):
|
|
|
|
|
- bad select() in audio driver (including ALSA's OSS emulation)
|
|
|
|
|
Workaround: ./configure --disable-select
|
|
|
|
|
- audio buffer problems
|
|
|
|
|
Workaround: mplayer -abs option
|
|
|
|
|
- slow machine (cpu or vga)
|
2001-04-30 22:58:22 +00:00
|
|
|
try with -vo null, if it plays well, then you have slow VGA card/driver:
|
2001-04-30 02:16:07 +00:00
|
|
|
Workaround: buy a faster card or read DOCS/VIDEOCARDS about how to speed up
|
|
|
|
|
|
|
|
|
|
Audio delay specific to one or a few files:
|
|
|
|
|
- bad file (pleae upload the file, so we can check & fix)
|
|
|
|
|
Workaround: -ni and/or -bps options
|
|
|
|
|
-delay option or +/- keys at runtime to adjuts delay
|
2001-04-30 22:58:22 +00:00
|
|
|
- your soundcard doesn't support 48Khz playback
|
2001-04-30 02:16:07 +00:00
|
|
|
Workaround: buy a better soundcard...
|
|
|
|
|
- file has VBR mp3 audio
|
|
|
|
|
Workaround: mplayer -mc 0
|
|
|
|
|
|
|
|
|
|
After many > or ^ (fast forward) audio vs. video is going out of sync (ASF/AVI)
|
|
|
|
|
- bug in mplayer code (a-v sync probs after seek... not really bug but
|
|
|
|
|
my avi/asf seeking code is not perfect yet)
|
|
|
|
|
|
|
|
|
|
Signal 11 in decode_audio:
|
|
|
|
|
- mp3lib doesn't handle (yet) well bad/broken audio streams
|
|
|
|
|
Workaround: -afm 4
|
|
|
|
|
- if it's still bad, try with -nosound [and report the bug, see BUGREPORTS]
|
|
|
|
|
|
|
|
|
|
No sound at all:
|
2001-04-30 22:58:22 +00:00
|
|
|
- your file uses an unsupported codec
|
2001-04-30 02:16:07 +00:00
|
|
|
Workaround: read DOCS/CODECS, and help us adding support for it
|
|
|
|
|
|
|
|
|
|
Video-out problems:
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
First note: options -fs -vm and -zoom are just recommendations, not (yet)
|
|
|
|
|
supported by all drivers. So it isn't a bug if it doesn't work.
|
|
|
|
|
Only a few driver supports scaling/zooming, don't except this from x11 or dga.
