Description Joerg Schaible 2005-07-13 16:53:51 UTC

kdetv-0.8.7 does not find any channels and is not able to display any channel 
from an imported list that works with kdetv-0.8.4. I have masked this version 
on my box, since 0.8.4 (the last tsable) works without any problems. 

Reproducible: Always
Steps to Reproduce:
1. start kdetv 
2. 
3. 
 
Actual Results:  
No channel is found, sound is muted. 

Expected Results:  
A TV channel. 

I am not sure, what is the useful info to provide in this case. My video 
driver saa7134-empress works, if I load it as module automatically at startup.

Joerg: No one else seems to have the problem and I couldn't find anything in
bugs.kde.org either. Since I'm just caring if kdetv compiles (I don't even have
a tv card.), I can't definitely say if this is a bug or a local problem, even
though I guess the latter is more likely.

Do you have the problem with 0.8.8?

Comment 2 Joerg Schaible 2005-10-07 13:56:50 UTC

Hello Carsten, 
 
unfortunately still the same. I'll try now on the mailing list of kdetv ... 
I'll update here if I get any new info. Please keep 0.8.4 in the tree unless 
this is solved. 
 
Thanks, 
J

What means "might"!? Apply the patch and you know it. :)

Comment 6 Joerg Schaible 2005-11-14 11:18:24 UTC

Hi Carsten, 
 
meanwhile I found time to upgrade my kernel (now already to latest stable 
2.6.14-r2), but the saa7134.c driver still misses the initialization of the 
type member in the structure. After applying the patch published in the kwintv 
(and video4linux) list, latest kdetv works like charm. 
 
How to proceed? IMHO this bug must be reassigned to the kernel devs, they will 
report upstream. 
 
Regards, 
J

Comment 8 Joerg Schaible 2005-11-14 11:27:05 UTC

Gosh, unfortunately I have to revoke my last report. kdetv-0.8.8 can initialize 
the driver only sometimes. Most of the time I still have the an error if I 
start the app ... will investigate further.

Comment 9 Joerg Schaible 2005-11-14 12:14:44 UTC

kdetv seems now only working the first time it is invoked (or the first time 
the driver is initialized). Funny thing is, that the reported errors on the 
console during startup seem quite equal, but closing kdetv seems to trigger an 
unrecoverable error in th v4l2 driver (without the kernel patch, the tuner 
cannot even be found):

Also kdetv works with the older v4l driver, it is just the v4l2 driver that 
fails.

Was this ever resolved?  If so, the bug can be closed.

Comment 11 Jorge Manuel B. S. Vicetto (RETIRED) Gentoo Infrastructure

As this appears to be a kernel driver / v4l2 issue and there has been no related activity for almost 18 months, I'm closing the bug.

Joerg,

if you still haven't solve your issue, take a look at the following links:

Comment 12 Joerg Schaible 2007-04-02 18:58:55 UTC

I still use V4L1 drivers ... but I have not checked V4L2 drivers for quite some time.
