Video Quality/VDPau - akr884 - 2010-11-04
I read on another thread that VDPau is activated with tvheadend, but I wondered if someone could clarify because:
I've played around with VDR VNI server and it seems like the video quality is subjectively better. I don't get motion streaking that I get with tvheadend on SD and HD channels and the picture quality just generally looks better.
Also with tvheadend, if I have automatic selection under the video mode dialog (while watching a video) then I get stuttering on HD channels until I turn it to 'none', but then I have bad motion streaking (really noticeable with white scrolling text).
I have an AverTV Volar Black HD tuner and a Zotac MAG nvidia ion box under Ubuntu 10.4.1 Lucid with Dushmaniac's svn for XBMC and tvheadend up-to-date.

disable deinterlacing on channels that are not interlaced
It seems like that was the default for all channels to deinterlace - I get dvb-t signal here in Spain, and I just read that deinterlacing is for analog and 1080i signals which makes me think I shouldn't need it activated.
Generally though, there's a motion blur with tvheadend + XBMC that deinterlacing helps with at the cost at producing blurrier still images (tv station logos are blurrier and sometimes 'jump' around a little bit with deinterlacing enabled).
EDIT: So I did a test with VDR + XBMC vs tvheadend + XBMC and they both have the motion blur, probably my crappy tv tuner card.

Quote:EDIT: So I did a test with VDR + XBMC vs tvheadend + XBMC and they both have the motion blur, probably my crappy tv tuner card.mine is set to "(VDPAU) Temporal" and the image is fine here. If I don't enable deinterlacing I get distorted images when there is a lot of movement on the screen.
- akr884 - 2010-11-05
Thanks a lot for the response dushmaniac. That helps a lot to smooth out the motion blug and it doesn't cause any stuttering on the HD channels.
I makes me wonder why 'Automatic Selection' wouldn't chose VDPAU (temporal) by default though for deinterlacing.
- opdenkamp - 2010-11-05
I don't think the autodetect thing is working (properly) at the moment.
I just put a new build of xbmc on my ppa which will be published within 30 minutes with a new setting: "EPG offset correction".
If your EPG times are off, go to the tvheadend addon options and change the "EPG offset correction" (which is in hours). After changing that setting, clear your EPG database or it won't work.
edit:
I also added builds for Karmic. Same warning as for Maverick: these builds have not been tested. The only check I did on those are installation checks. If it doesn't work for you, report it here or use the Lucid builds.
If you're not running Ubuntu, grab the updated sources from github: git://github.com/opdenkamp/xbmc.git

Hi,
just upgrade to your new version: tested it and can confirm that it works but I am not sure if it works as expected.... when I set an offset of -1 it adds 1 hour to the start time: I would expect that it would deduct 1 hour?
Also it would 'feel' more natural if the offset variable could be set in the epg part of the tv config instead of in the pvr addon... not sure if this is possible tho
regards,
Ruud.

Ruud Wrote:when I set an offset of -1 it adds 1 hour to the start time: I would expect that it would deduct 1 hour?This is the way I expected it to work, because adding to the offset is compensated. I'l do it the otherway around in the next version so it'll "feel more natural"
Quote:Also it would 'feel' more natural if the offset variable could be set in the epg part of the tv config instead of in the pvr addon... not sure if this is possible thoeverything is possible, but I put it away in the tvheadend addon because I didn't want to change anything in the other pvr sources until they are merged with trunk.
edit:
the offset correction is inverted now on git. it'll be included in the next build.

you're right when looking from that perspective
but -1 for deducting and +1 for adding is more intuitive 
Keep up the good work!
highly appreciated

Ruud.

When i try to watch a live TV channel i get "no input detected" This is from a machine running xbmc beta 4 remotely against the TVheadend server...
Any ideas?

That error is reported by tvheadend and means that channel can't be received (bad signal?) or is not transmitting anything.
Check your tvheadend logs and check your signal (or record a couple of minutes via the webui and try to play that). Also, you might want to try upgrading your tvheadend. You're running svn rev. 4965 and tvheadend's currently at rev 5558. This problem could have been fixed already.

I tried to apply your patch to tvheadend trunk and got the following error:
Code:
git apply --check 0002-add-signal-status-in-HTSP.patch
error: patch failed: src/transports.c:1050
error: src/transports.c: patch does not apply
error: patch failed: src/transports.h:100
error: src/transports.h: patch does not apply- opdenkamp - 2010-11-06
probably some change in tvheadend that prevents it from applying cleanly. I'll update them later today.
the problem with choppy sound on radio channels is fixed on git. it'll be included in the next ppa build.
