The VideoLAN Forums

I would like to ask you about one fix developped regarding the standard selection (PAL, SECAM, ...).
I live in a country where the standard is SECAM_K1 and I use vlc 1.0.6 under linux:

Under Fedora 12:
vlc-1.0.6-1.fc12.i686
vlc-core-1.0.6-1.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=co ... 7c342b7236

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

Thanks by advance for you replies

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.

Thanks Remi for this answer, I try to contact V4L2 mailling list but I have a question:

On some others posts I have found several peoples with previous version of vlc and they do have the SECAM-K1 selection when using VLC:
So why do they have this choice and not me? Is it my V4L2 version that may not have this any more?

For instance this post: http://88.191.250.119/viewtopic.php?f=13&t=63302

Then maybe your video adapter does not support SECAM-K1.

Hello Rémi, I have found this document:

http://v4l.videotechnology.com/dwg/v4l2.pdf

Page 88 it is said:

#define V4L2_STD_SECAM_DK (V4L2_STD_SECAM_D |\
V4L2_STD_SECAM_K |\
V4L2_STD_SECAM_K1)

So maybe you were right when saying that in any case one of the standart should be ok.

What do you think?
