 |
|
Hi all,
I am experience problem with picture (video) quality on my PVR-250 card.
I am having lines on the picture when moving (motion). I switch the tuner and the composite and the S-video -= all have the same issue, before it was only Composite I believe.
It used to be fine, but I believe I change some setting and now it is not working.
Any ideas how can I reset the card (I reload the firmware and etc but did not help)
here is the full info:
ivtvctl -a

| By lines, might you mean interlacing? If so, enable deinterlacing in whatever you're watching it in. |

How to do it?
I will check man page but if you have a short answer ... |

Well, which app are you using to view? It's in different places in different apps.
For example (in MPlayer):
mplayer -vf pp=lb /dev/video0 |

It is working as a champ,
but can you tell me can I do it on the driver or kernel level,
so I do not need to pass that parameters on the specific program?
Thank you |

Closest you'll get in the driver level is:
ivtvctl -c pulldown=1
But that won't get it all. You need some sort of deinterlacing, which isn't possible currently in the drivers, so you have to set it at the application level. |

I have a similar problem: with my PVR-250, ivtv 0.4.2 and kernel-2.15-r1 (AMD 3800+), it seems that i can no longer tune my card reliably. The picture is wavy and distorted (i don't believe it's interlaced vs non-interlaced), but there is sound. It wasn't until I went back to kernel 2.14-r5 that I can use my PVR-250. The PVR-150 in the box seems to tune just fine with both kernels.
I'm using mplayer-bin to read /dev/video0 (PVR-250) and /dev/video1 (PVR-150).
I'm sorry, I don't intend to hijack, but I'm curious if something changed between the two kernel versions. |
