ivtv, kernel 2.6.27, secam TV, Hauppauge PVR-350 : no sound on non stereo channels
Hi,

I'm a very new member of this list, and I stat here to complains (how
bad !)

I use hauppauge cards since a few year, under linux and with ivtv. (a
PVR 350 and a PVR 150). each card is in a different system running freevo.

Yesterday, I updated one of the system to Mandriva 2009 (Thas is, a
kernel 2.6.27, and ivtv 1.3.0). Just before, my two systems were running
with a 2.6.24 kernel.

I live in France, and receive analog program trough a Cable Operator.
The 23 analog channel are in secam.

After the update, I noticed that most channel didn't have any sound.
Searching further, I discovered that channels I can hear are sendind the
audio signal in stereo (SECAM stereo is NICAM, a numeric soundtrack
encoded in some unseen video lines in the picture, because original
SECAM sound modulation was AM, and not updatable to stereo). Other
channel were muted.

I finaly found that this behavior can be changed :

By default, freevo set the tuner in 'generic secam' : v4l2-ctl -S tell me :

$ v4l2-ctl -S
Video Standard = 0x00ff0000
SECAM-B/D/G/H/K/K1/L/Lc

French flavour of SECAM is SECAM L. If I set the tuner for SECAM-L :

$ v4l2-ctl -s secam-L
Standard set to 00400000
$ v4l2-ctl -S
Video Standard = 0x00400000
SECAM-L

Then I have again sound.

Here the question : should I consider that new way like a bahaviour ? Or is that a 'bug' ?

In the later case, I should be able to do any needed tests, if useful.

Thanks,
Pascal

It would be interesting to not start freevo and do:
cat /dev/videX > test.mpg

And see if this does give you sound.

Probably not a bug. Before you run freevo run v4l2-ctl --log-status.
Could you post this? It is always good to include the complete ivtv
init start to end (don't grep for only ivtv) from the kernel log.

And now I complain as I already replied to your e-mail [1].

To begin, thanks for your answer !

Reading your mail, I just stopped (power off) and started again my test
server.
After that, to be able to test something, I did the following :
v4l2-ctl -s secam (default value to PAL)
v4l2-ctl -f 679.250 (One of the faulty channels)
cat /dev/video0 > a.mpeg (around 10 seconds)
mplayer a.mpeg --> no sound
v4l2-ctl -s secam-l
cat /dev/video0 > a.mpeg (around 10 seconds)
mplayer a.mpeg --> sound !
v4l2-ctl -s secam and again no sound

Hi Pascal,

It's not a bug, it's the right behavior. I'm even a bit surprised that
this has worked in the past. Setting generic secam is a bad thing to do
as there is really no such thing. In practice you have SECAM-BG,
SECAM-DK and SECAM-L. And it is basically undefined what will happen if
you just set SECAM.

Regards,

Hans

I'm not sure how freevo handles standards, but the right way is to use
VIDIOC_ENUMSTD to enumerate the standards that a driver supports. That
should give a valid list of formats.

Hans

Hi,

Just for the record : finaly, freevo is able to deal with SECAM sub norm
(PAL also, by the way).

So, and at least on my system ;-) since ivtv 1.4.0, I can no more use
the secam generic mode witch was working before. I have to set in the
freevo.conf file secam_l (with an underscore and not a minus sign).

Thanks again,
Pascal
