I've just tried the ivtv driver from subversion (today, 2637) with
version 0.10.6 of the X driver, and they provide by far the best yuv
playback that I've experienced. The jitter that I saw with 0.3.6x and
earlier (which looked like the scanlines were reversed) is now gone,
and scaling is working well.
I'm curious about the following lines in my log:
ivtv-osd warning: Need to adjust to width 720 src_w 720 dst_w 640 src_x 0
dst_x 40
ivtv-osd warning: Need to adjust to height 480 src_h 480 dst_h 480 src_y 0
dst_y 0
ivtv-osd warning: Using progressive mode
I want to make sure I'm capturing in a way that requires no subsequent
scaling, to optimize quality. The second line looks fine since it
seems to say that no scaling is taking place. (I'm curious why this
line is printed; the word "warning" suggests that maybe this isn't good
news.) For the first line, does it mean that there is scaling taking
place (because 640 != 720) or that there isn't (because 640+40*2 =
720)?
And about the third line, I'm capturing interlaced material and
displaying it on an (NTSC) interlaced TV, so I wonder why it says it
is using progressive mode. I did read a message from Ian on this
topic a few weeks ago, but must admit I didn't understand it...
Final question: I had one video in .mov format that I've tried with
mplayer (myth 0.18.1 seems to choke on it), and it has strange
diagonal color effects. Any ideas about that?
Thanks so much for this great software!
Dan
