Known bugs:
|
|
~~~~~~~~~~~
|
|
|
|
Special system/cpu-specific bugs/problems:
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
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 16bpp (x11,dga,fbdev,svga) playing
|
|
MPEG files on SMP machine:
|
|
Problem: bug(?) in MMX YV12->RGB16 converter code
|
|
Workaround: ./configure --disable-mmx
|
|
SOLVED: bug of gcc-2.96 - you should use 2.95.2 or 2.95.3
|
|
|
|
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. General SIGILL (signal 4):
|
|
Problem: you compiled and run mplayer in different machines
|
|
(for example compiled on P3 and runinng on celeron)
|
|
Solution: compile MPlayer on 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):
|
|
- bad select() in audio driver (including ALSA's OSS emulation)
|
|
Workaround: ./configure --disable-select
|
|
SOLVED: using ioctls instead of select in the new audio code
|
|
- audio buffer problems
|
|
Workaround: mplayer -abs option
|
|
SOLVED: using ioctls in the new audio code
|
|
- 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 (maybe -hardframedrop)
|
|
|
|
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)
|
|
|
|
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
|
|
|
|
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.
