 |
|
Hi,
I have this problem with the xv driver for mplayer:
when I put movies on the tv, it gives a strange line in the middle (its not really a line, but more like the screen wants to split in half). It is only visible when there is some cameramovement, and the more movement there is, the better it is visible.
Now I searched the forums for this but couldn't find anything (can't really come up with some good keywords I guess). I *think* it has something to do with interleaving, and the way a tv displays frames.
The thing is, this behaviour does not occur when using other drivers (X11, gl2 etc). I will use X11 for now but I rather use xv (because it is much faster).
Anyone with similar problems (or a solution  )? |

Hi. When I use the tvout I have this problem too with x11 or gl2 driver.
When I use the xv driver instead I cannot get a uniform play of the video frames.
I have a geforce fx5200 and emerged nvidia-kernel-1.0.6629-r1 but the problem isn't solved... |

Ah so you even experience it with other drivers. Hm. I have a Geforce 5600, I had 5200 with TVout and I am almost certain it had the same problem.
I think it might be something to do with deinterlacing or similar magic. I read a bit about it and a TV alternates odd and even lines every 1/60 second (It has a refresh rate of 60hz). So *maybe* if the signal is giving it too many frames to display, it forms this weird split in the middle...
I have tried some deinterlacing with mplayer, but without success. I don't actually know what settings to use (there are just too many). This is what I tried:
| Code: | | mplayer -vo xv -vf pp=hb/vb/dr/al/lb/halfpack -fs -vsync |
bubbles, this is getting nowhere... |

I've tried the videolan VLC player. It's not affected by the problem. There isn't screen splti using xv and x11 and the playback appears faster than mplayer.
Try it using the X server only on the tv.
Here my xorg.conf
| Code: | Section "Module"
# This loads the DBE extension module.
Load "dbe" # Double buffer extension
# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
SubSection "extmod"
Option "omit xfree86-dga" # don't initialise the DGA extension
EndSubSection
# This loads the font modules
