V4L & VLC 1.0.6 and standard selection

I am trying to catch my tuner card signal by using vlc and v4l

Under Fedora 12:
vlc-1.0.6-1.fc12.i686
vlc-core-1.0.6-1.fc12.i686

libv4l-0.6.4-1.fc12.i686
xorg-x11-drv-v4l-0.2.0-3.fc12.1.i686
v4l2-tool-1.0.3-5.fc12.i686

By using the cvlc command to catch the tuner card signal and setting standard in the command line I did not see the SECAM K1, so I wonder if the fix has been committed or not in this release or if I have to patch the sources:

http://git.videolan.org/?p=vlc.git;a=commitdiff;h=beb5d0fdc3c4b8b12ec385f96ab8a27c342b7236

I used:

$ cvlc -vv v4l2:// :v4l2-dev=/dev/video0 :v4l2-adev=hw.1,0
:v4l2-tuner-frequency=207250 :v4l2-standard=13 ....

I dont see SECAM K1

A developper from videolan told me this:
That list comes from the V4L2 driver for your analog TV capture card. It does not come from VLC. So we cannot "fix" it.
In any case, SECAM-K1 is probably one of the choice, but with a different name.

Does anyone know if some of the options can be applied to decode SECAM K1? ou K'

Thanks by advance for you replies

Use SECAM-DK. It is not significantly different from SECAM-K1:

http://www.pembers.freeserve.co.uk/World-TV-Standards/Transmission-Systems.html#CCIR

$ v4l2-ctl -d /dev/video0 --help
$ v4l2-ctl -d /dev/video0 --list-standards
$ v4l2-ctl -d /dev/video0 --list-inputs

$ v4l2-ctl -d /dev/video0 --set-standard=secam

or

$ v4l2-ctl -d /dev/video0 --set-standard=0x00320000
(SECAM-DK is defined as
 V4L2_STD_SECAM_D|V4L2_STD_SECAM_K|V4L2_STD_SECAM_K1 => 0x00320000 in
 include/linux/videodev2.h)

or

$ v4l2-ctl -d /dev/video0 --set-standard=0x00200000
(SECAM-K1 defined as 0x00200000 in include/linux/videodev2.h)

The setting should persist until you switch to another input (Tuner, SVideo, Composite). The Tuner input will limit what standard can actually be set for the tuner.

Andy
