-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 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 the 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
