bttv and ffmpeg

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi,

Does onyone have any experience with changing the norm (PAL, NTSC, SECAM)
with the bttv driver?

I have the bttv driver (v.0.7.73) on a 2.4.2 kernel running quite
successfully. xawtv works great but defaults to PAL. Creating a ~/.xawtv
file with 'norm=ntsc' does the trick and it works with ntsc.

However, I would like to use ffmpeg, except there are no commandline
switches to change the format. Is there a way to change the bttv driver to
NTSC? I am game for anything, commandline tool, or source changes to make
NTSC the default.

I tried the v4lctl ('v4lctl -v 1 -c /dev/video0 setnorm NTSC') tool but it
doesn't seem to make any permanent changes. I edited 'bttv-driver.c' about
line 2500 where it talks about default and it didn't make a difference
either.

I am really lost here!

Regards,
Adi Linden
