[FFmpeg-user] Unknown standard 'NTSC' in v4l2

Hi all,

I'm having some trouble with video4linux2

The error I'm getting is :

[video4linux2 @ 0x97f2540] Unknown standard 'NTSC'
[video4linux2 @ 0x97f2540] Could not find codec parameters (Invalid Codec type -1)

This is happening on the git version 263f57c6d76b27e1895c4001f815824a463b1592 (which is of 6-6-2011)
This doesn't happen on git version d84f191d37b8123203dff250531a4b4c0d5f587a (which is of 26-4-2011)

I did find a commit which I think must be related (b3da2692115ea17190544883d15efa36219da99e) ... something about a video standard option, but my C knowledge is non existent.

I'm aiming to keep up with the latest ffmpeg, so I'd rather not revert back to before that commit.
My system is running on openwrt, kernel 2.6.32.27, which might be the problem.

Am I missing something in the v4l2 driver maybe ?

--->update seems there was already a fix in git (af344a69f3a8240b508183586617fba6af698bb2) but it isn't in the definitive v4l2.c ...... strange, maybe a later commit changes it back ?? will investigate and report here...
