VDR - VNSI5 - VAAPI Timeshift Artefacts - -DDD- - 2014-01-13
I have sometimes Artefacts when viewing LiveTV with Timeshift enabled in RAM.
It looks like http://abload.de/img/screenshot002q5sku.png
My Logs - http://xbmclogs.com/show.php?id=110187
i think that could be the problem:
PHP Code:

I have OpenElec version r16713 running on Intel HD4000 Ivy Bridge.
The Issue exists on 576i and 720p Channels also. Sometimes i can play the recorded Video for an hour before the
Failure happen, sometimes it takes some minutes.

vaapi even shows artifacts for mpeg2 without timeshift. I opened a bug on freedesktop:
https://bugs.freedesktop.org/show_bug.cgi?id=73424
unfortunately vaapi has a couple of issues.
RE: VDR - VNSI5 - VAAPI Timeshift Artefacts - -DDD- - 2014-01-13
I think that should be h264
PHP Code:

I don't have this Issue when watching LiveTV without Timeshift
RE: VDR - VNSI5 - VAAPI Timeshift Artefacts - FernetMenta - 2014-01-14
The screenshot is 576i (SD), this is mpeg2.
I don't see this issue on my testsystems which are either vdpau (Nvidia + AMD), sw decoder, dxva, , RPi, or vaapi (haswell, i3/i5).
So the most likely reason for this is an issue in vaapi + ivy bridge driver. I will ping fritsch, maybe he can run some tests on his system.
RE: VDR - VNSI5 - VAAPI Timeshift Artefacts - -DDD- - 2014-01-14
Yes, the Screenshot is not this Bug here, this was another Bug, but it looks similar to this.
I can try to screenshot this Issue if it would be helpful.
RE: VDR - VNSI5 - VAAPI Timeshift Artefacts - fritsch - 2014-01-14
I tried to reproduce this, by setting Timeshift to RAM, 5 x 100 MB which is my default settings. Then my gf watched "In aller Freundschaft" on ARD for more than one hour - without a single issue, here is the logfile: http://paste.ubuntu.com/6752435/ (see 20:11 until 21:30) nothing in the logs.
Hardware: Celeron 1007, Lanczos 3 Optimized for this 720p.

Today i also can't reproduce this on KiKa HD.
I will reply here when it happen again, with new Logs and Screenshots.
