I won't try to justify me on this .... but the readme.txt says :
TVon=<0|1> - enable/disable TV output (default 0)
TVtype=<0|1|2> - set TV type to none/NTSC/PAL (default PAL)
TVoverscan=<0|1> - enable/disable overscan mode (default 0)
so i deduced 0=enable 1=disable ...
all this time lost for this stupid and so logic TVon=1 ;)
Fine, now i have a nice TVout.
2006/9/17, Public TESTASECCA <[EMAIL PROTECTED]>:
Hi all, i posted on users but there is not a lot of activity on it, so i
post here ... forgive me if it is not the good place.
I'm new to the list, and of course with a problem ....
I'm a trying to install a TV Box running VDR on an EPIA M 10000 board,
under Ubuntu (server install), kernel version is 2.6.15-23-386.
I want VDR running onto the framebuffer throw softdevice plugin, and i
want hardware MPEG acceleration.
So, i found this nice tutorial :
http://www.mellander.org/per/projects/linux/?chapter=epia-hw-cle266 ...
Everything works perfectly on my PC monitor, i got : the famebuffer
console, i can see VDR interface, decode an MPEG stream with
acceleration ...
BUT my TV screen goes crazy ! It is activated but completly scrambled,
there is some lines ( looks like interlacing problems ??, the image is
shifted, duplicated .... ).
This problems comes just after viafb/fbcon module inserting, so
there'is no problem with DiretFB, or DF++ or VDR, the problems comes
from viafb module.
I have configured into the BIOS (TV+CRT, 800x600, PAL (i'm in france),
direct access to framebuffer .... ).
Then i load the module :
sudo insmod viafb.ko TVon=0 # (0 is for enable, i tried without
options, same results ...)
When i insert the viafb module, dmesg gives :
[4296000.354000] viafb: VIA UNICHROME framebuffer 1.0 initializing

and fbset -i :

then the set gives :

endmode
That's weird, everything is working on PC screen, and not on TV !
I tried a patch to the kernel from VDR Eclipse site, with the same bad
results.
( http://vdr.bluox.org/download/epia/viafb_03-720x576noscale-2.6.14.patch.bz2)
I've also tried via driver and TV out works (with the same fb.modes)
but is really slow ! I can't decode an MPEG stream with this !
I'm a little bit disapointed ! Please Help ! :)
Some not directly related questions :
Do you know how to prevent fbcon module insertion at boot time ? ( I
tried to remove it from /lib/modules/ ... and it was stille loaded after
reboot !!! Magik ? Initrd ?
Do you know how to force a power off on an USB device? i want to stop
USB power supply to my DVB-T USB device to make a hard reset to it, it
seems to very stable ....
Thanks in advance for your help ...
Cheers
