This site has all the info you'll need: http://klk64.com/wintv-hvr-1950/ Note that this outputs an mpeg stream, so you'll need to mplayer /dev/video0 (composite input) or mplayer /dev/dvb/adapter0/dvr0 (antenna/cable ATSC input) to see images; xawtv and others won't work with it. Also note that it does not have a vertical blanking information (?) VBI (/dev/vbi) interface - so scan needs to be redirected to /dev/NULL, as mentioned on the page above. To switch to composite input, use: v4lctl setinput composite. To switch to full resolution, v4lctl snap jpeg 640x480 ~/test.jpg seems to do the trick (also can switch to QVGA this way, if you like) To read from the device programmatically, the code available here worked out of the box: http://web.me.com/dhoerl/Home/Tech_Blog/Entries/2009/1/22_Revised_avcodec_sample.c.html (well, it didn't terminate -- there is no end to that file :-) -- but it wrote the images fine!) |
