[directfb-users] Re: [MPlayer-dev-eng] matrox 550 tv out andmplayer problem



I removed aspect=1.5 from the command line. Chunky artifacts go away, but
I now get jerky motion similar to the -vop pp=0x20000 option. fieldparity
settings
don't seem to have any effect.

Even more info:

the -vop pp=0x20000 options gets rid of the "chunky" interlacing artifacts,
but replaces
it with jerky motion.

More information.

After a careful viewing on my COMPUTER monitor, I noticed that the initial
sequence (which
plays fine on the TV) also looks fine on the computer monitor. The sequence
that is screwed up on
the TV is loaded with interlace artifacts on the computer monitor.

No unexpected artifacts on the computer monitor.

I can't completely confirm this yet, but it seems to be related to
framerate. All
the disks that show the problem eventually say something like

------
A:   0.8 V:   0.7 A-V:  0.110 ct:  0.037   15/ 12   0%  0%  0.0% 0 0 0%
demux_mpg: 3:2 TELECINE detected, enabling inverse telecine fx. FPS changed
to 23.976!
A:   2.7 V:   2.7 A-V:  0.015 ct:  0.083   63/ 60  33% 33%  3.3% 0 0 0%
demux_mpg: Progressive seq detected, leaving 3:2 TELECINE mode
Warning! FPS changed 23.976 -> 29.970  (-5.994000) [4]  3%  3.3% 0 0 0%
A:   6.8 V:   6.3 A-V:  0.499 ct:  0.441  172/169  56% 31%  3.6% 79 0 0%

---------------

or something like that.

Could there be some issue with disks that are actually encoded at 29.97?

And can you see any artifacts when you watch it on a monitor?

If the problem is indeed interlacing you can try to use the fieldparity
option to get rid of it. But that works only if the field parity stays
constant.
