[MPlayer-users] bug report on the fbdev/multiple files crash problem

[Roberto De Leo]

Hi,
I have the very same problem that Siim is talking about, and I 
experienced it with two
very different settings:
1. mplayer 0.90rc2, AMD 1GHz w/ Ati Radeon VE, kernel 2.4.20 w/ vesa FB, 
gcc 3.2
2. mplayer 0.90rc1, AMD XP 1.7GHz w/ G400, kernel 2.4.18 w/ matroxfb, 
gcc 2.95.3.
The error is always the same. To use the very same Siim words:

 >Whenever I use "mplayer -vo fbdev <file1> <file2>" (or -playlist) it does
 >play <file1> but then with <file2> it crashes with following output:
 >fbdev: Can't put VSCREENINFO: Invalid argument
 >FATAL: Cannot initialize video driver!
 >init_vo failed

Here is my bug report for one of the two systems:

System data:

Distribution Slackware 8.1 heavily patched

CPU: AMD Athlon(TM) XP 1700+

Kernel:
Linux nehwon 2.4.18 #12 Tue Aug 6 12:19:25 UTC 2002 i686 unknown

When I try to play

mplayer -vo fbdev a2.avi a1.avi I get the following log:

MPlayer interrupted by signal 11 in module: uninit_vo
- MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with 
--enable-debug and make a 'gdb' back
trace and disassembly. For details, see DOCS/bugreports.html section 5.b.
- MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer 
code _or_ in your drivers _or_ in
your gcc version. If you think it's MPlayer's fault, please read 
DOCS/bugreports.html and follow instruct
ions there. We can't and won't help unless you provide these 
informations when reporting a possible bug.

If I use fbdev:vidix instead of the simple fbdev I get a slightly 
different error:
