I have not been able to test the v4lctl method since I do not have X on the machine. Does v4lctl require xawtv? I suppose I could try and install X but I would rather not if possible. Also, I'm not sure about Astra or Eutelsat since my dish is in America. I just went ahead and installed X and xawtv. It appears the v4lctl method does work and the kernel option does not. I wonder what the difference is between the two. Best Regards. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

I wonder what the difference is between the two. AFAIK: The TV-out connectors in the dvb-ttpci board output automatically NTSC if the stream is NTSC. They output automatically PAL when the stream is PAL. When there is no stream (channel switch or the like), they output PAL by default, or NTSC if the tv_standard kernel option is used to select that. The output from /dev/video0 file is PAL all the time, unless it is changed by the proper V4L ioctl, which is done by VLC and v4lctl. -- Anssi Hannula ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

I hope so because installing x to do this seems pretty unreasonable. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
[vdr] setting tv standard in /dev/video0
Hi,
I am currently using VDR with a Nexus-S FF card in an NTSC environment. For
a long time, I could never get the correct tv standard (NTSC) while trying
to watch television via VDRAdmin. I recently noticed that once I stream VDR
using VLC and its v4l interface, something in /dev/video0 gets set to NTSC,
because from then on, the video is correctly set to NTSC mode and I can
watch television via the VDRAdmin television interface. Here is the VLC
command I'm using:
vlc -vvv v4l:/dev/video0:adev=/dev/dsp:audio=1:norm=ntsc:size=352x240 --sout
'#transcode{vcodec=DIV3,vb=64,acodec=mp3,ab=48,deinterlace}:std{access=http,mux=asf,dst=:6789}'
Notice how VLC is directly interacting with the video from /dev/video0 (this
method only works with FF cards). Somehow, the v4l interface from VLC is
setting the tv standard properly for /dev/video0 and fixing VDRAdmin for
NTSC. Anyone have an idea whats going on? The firmware is set to NTSC as
soon as the card tunes to a NTSC channel. Why would /dev/video0 not be set
to NTSC until I stream it with VLC?
Best Regards.
