Linux VLC Without X-Windows

[sibloon]

I am just a newbie with VLC. I plan to use VLC for Linux without any X-Windows. I can use mplayer with svgalib, directfb, VESA, etc. When I try VLC, there are errors:

How to solve this problem?

Thank you.

You should give the command-line you used for this debug output.

Did you provide a -I parameter? You could call VLC like this to get rid of GUI:

Code: Select all

vlc -I dummy ..other params..

You can also set a http or telnet interface (-I http and -I telnet), try to unset $DISPLAY variable too.

Looks like a crash inside svgalib.

Thank's for the reply. I don't use $DISPLAY environment variable, but I use "SDL_VIDEODRIVER".
A. SDL_VIDEODRIVER=svgalib or SDL_VIDEODRIVER=fbcon:
Illegal instruction.
B. SDL_VIDEODRIVER=directfb: audio OK, but the display is only a blue screen with a black square in the centre.

The conmmand line is: "vlc -I dummy test.mp4"

> Breakdown in svgalib.
Is this a bug inside svgalib or VLC?
Is it possible to pass video driver type, video resolution, color depth to VLC using command line parameters?

[sibloon]

I try to re-compile and run vlc with "--vout svgalib". The audio OK.
The video is OK, except the color is incorrect. Black becoming blue etc. Here is the result:

vlc -I dummy --vout svgalib test.mp4

and other similar "subpicture error" messages.

How to solve the color problem?

Thank you.

[sibloon]

I have tested various version of vlc with parameter "--vout svgalib".

The result;
A. Version 0.8.2, 0.8.6 and 0.8.6.f: Video OK, The color is correct.

B. Version 0.9.0, 0.9.2, 0.9.4, 0.9.6 and 0.9.8a: Video OK, but the color is wrong: Black become blue, etc.

Perhaps there is a modification from version 0.8.6 to 0.9.0 that messed up the color on svgalib output.

Can someone debug and fix this problem?

Thank you.
