2.2.1.A.1. Matrox cards

-

What I'd love to see in mplayer is the the same feature that I see in my -windows box. When I start a movie in windows (in a window or in full screen) -the movie is also redirected to the tv-out and I can also see it full screen -on my tv. I love this feature and was wondering how hard it would be to add -such a feature to mplayer.

It's a driver limitation. BES (Back-End Scaler, it's the overlay generator -and YUV scaling engine of G200/G400/G450/G550 cards) works only with CRTC1. -Normally, CRTC1 (textmode, every bpp gfx and BES) is routed to HEAD1, -and CRTC2 (only 16/32bpp gfx) is routed to HEAD2 (TV-out).

- -

Under linux, you have two choices to get TV-out working:

- -

- -

Follow these instructions:

- -

- -You should edit your config file, to contain the screenw and -screenh options (the first should be set to the horizontal -resolution of the framebuffer, and the latter to the vertical. See -example.conf). This is required for fullscreen playing, and for -the aspect code to work.

- -

Yes, it is a bit 'hack' now. But I'm waiting for the marvel -project to be finished, it will provide real TV-out drivers, I hope.

- -

My current problem is that BES is working only with CRTC1. So picture -will always shown up on head routed to CRTC1 (normaly the monitor), -so i have to swap CRTC's, but this way your console will framebuffer -(CRTC2 can't do text-mode) and a bit slow (no acceleration). :(

- -

Anyway i also just get monochrome output on the tv ...
-Maybe you have NTSC TV? Or just didn't run one of TV-* scripts.

2.2.1.A.1a. Matrox cards (method 2 - the XFree approach)

- -

The previous method doesn't work very good for X users, since either they -have to shutdown it, or it becomes uselessly messy. This section is for them.

+

Under Linux you have 2 methods to get TV out working :

-

  • compile the matroxfb stuff to modules
    • -
  • load modules with the ./modules script
    • -
  • turn on display cloning with ./cloning . This way CRTC2 -won't be used, CRTC1 will display on both heads. -
  • execute ./TV-640x512 or whichever resolution you -wish to use
    • +

    -

    Now you should have a clean picture on the TV, and maybe a somewhat strange -picture on the monitor. But monitor doesn't matter, start X. Your TV -goes black or have strange stripes, but monitor/X is fine !
    - -

    -So, anytime you want to start watching something on TV, just start -MPlayer in X with the -vo mga -screenw XXX -screenh XXX -(write the horizontal and vertical resolution of your framebuffer to the XXX's, -respectively) options, change to tty1 (with ctrl-alt-f1), and turn off the -monitor. -
