Znane problemy:
~~~~~~~~~~~
Szczególne, zale¿ne od systemu/CPU :
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. SIGILL (signal 4) in draw_frame, on P3 (mostly with 2.2.x kernels):
Problem: movups is crashing in libvo/fastmemcpy.h
Workaround: ./configure --disable-fastmemcpy
SOLVED: disabled SSE code in fastmemcpy.h ;(
2. No image (black image) in RGB 15/16bpp (x11,dga,fbdev,svga) playing
MPEG or OpenDivX files:
Problem: gcc 2.96 bug
Workaround: ./configure --disable-mmx, or use gcc 2.95.x
SOLVED: code fixed
3. SIGILL (signal 4) or other fault at loading l3codeca.acm:
Problem: shared libs are loaded to 0x00xxxxxx instead of 0x40xxxxxx
Workaround: mplayer -afm 1 ...
SOLVED: you are using some security kernel patch, like OpenWall etc.
4. SIGILL (signal 4) on P3 using 2.2.x kernels:
Problem: kernel 2.2.x doesn't have proper (working) SSE support
Solution: upgrade kernel to 2.4.x
Workaround: ./configure --disable-sse
5. General SIGILL (signal 4):
Problem: you compiled and run mplayer in different machines
(for example compiled on P3 and running on celeron)
Solution: compile MPlayer on the same machine where you will use it!
Workaround: ./configure --disable-sse etc. options
Various A-V sync and other audio problems:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
General audio delay or jerky sound (exists with all or many files):
- audio buffer problems (buffer size badly detected)
Workaround: mplayer -abs option
- slow machine (cpu or vga)
try with -vo null, if it plays well, then you have slow VGA card/driver:
Workaround: buy a faster card or read DOCS/VIDEOCARDS about how to speed up
SOLVED: try -framedrop
Audio delay/de-sync specific to one or a few files:
- bad file (please upload the file, so we can check & fix)
Workaround: -ni or -bps option (for non-interlaved or bad files)
-mc 0 (required for files with VBR audio)
-delay option or +/- keys at runtime to adjust delay
- your soundcard doesn't support 48Khz playback
Workaround: buy a better soundcard...
or try to decrease fps by 10% (use -fps 27 for a 30fps movie)
- slow machine
(if A-V is not around 0, and teh last number in the status line increasing)
Workaround: -framedrop
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)
Workaround: -bps
SOLVED: code fixed (but -bps still can help)
Signal 11 in decode_audio:
- mp3lib doesn't handle (yet) well bad/broken audio streams
Workaround: -afm 4
SOLVED: fixed mp3lib, it must be rock solid now!
- if it's still bad, try with -nosound [and report the bug, see BUGREPORTS]
No sound at all:
- your file uses an unsupported codec
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 expect this from x11 or dga.
OSD/sub flickering:
- x11 driver: sorry, it can't be fixed now
- xv driver: increase number of buffers in libvo/vo_xv.c, and recompile all
