[linux-dvb] apps/test/video.c not working with new driver?

[Benjamin Reichardt <reichard@math.uni-goettingen.de>]

Hallo,

now that a new driver-release is approaching, I wanted to test the new 
features. Before that I have been using the driver from 20/05/2002 
for almost one year (controlled by vdr 1.0.4). Because I do not have 
a TV set in my room and no X on my DVB-computer (a computer with one 
full featured DVB-s board in it), I used the apps/test/video.c 
program which is provided with the driver to watch TV via the Linux 
frambuffer infrastructure (3Dfx Banshee framebuffer). With the old 
driver this was working fine.

So yesterday I tested the linuxtv-dvb-1.0.0-pre2 driver. It is working 
fine with vdr 1.1.26 (I really like the possibility to do 
time-shifting with only one DVB-s :-). But only if I watch via 
video-out of the DVB-s. My computer monitor stays blank when I start 
apps/test/video. But there is no error message (and no syslog entry) 
from apps/test/video. The new standby functionality should not be the 
reason, since there is a picture on the video-out of the DVB-s 
(obviously the frontend is still opened by vdr). And the changes in 
apps/test/video.c cannot be the reason either, since the new version 
(from linuxtv-dvb-1.0.0-pre2) works when I unload the new driver and 
use the old driver instead. This should also eliminate the 
possibility that the framebuffer configuration is the reason.

What else could be the reason? Hav the semantics of /dev/video0 
changed and apps/test/video still uses the old way of accessing it? 
What am I missing?

I tried "fbtv -q" from the xawtv package, it did not work either. 
Except once last night. But I could not reproduce that after I 
restarted the computer. Perhaps one of the modules of the old driver 
was not unloaded.

Thanks for your help (and, of course, for providing this great 
software! ),

Benjamin
