Hauppauge WinTV PVR-350 Composite-Out gives distorted image under Linux.
Posted on 2004-04-01
After checking that everything of the PVR-350 worked under Wind-nose I set out to install mythtv on my linux partion. And after a hard struggle I triomphed! (And went a bit wauuuga! over it, man wat a good programe and it's still a beta version) But I still have a problem. I set up the TV-out port by activating the ivtv-fb.o module. After starting:
insmod saa7127 enable_output=1 output_select=0 test_image=1
Which should select composite out and show an image with coloured stripes on the tv. But in my case it showed only a gray-scale image. On switching myth to livetv it showed the feed in back-and white and it was stretched twisted to the lower right corner. Just like it couldn't find the vertical hold. Sound was ok.
/usr/local/bin/test_ioctl -d /dev/video16 -u 0xff
to select PAL did not help (/dev/video16 is the correct tvout device).
selecting output_select=1 did not help either.
Is this perhaps a NTSC vs. PAL problem? I have a PAL-B tv.
Or is the an 'undocumented feature'?
Has anyone some handy pointers?
