Hi All,

I've been running TVHeadEnd as a VDR backend for my ION-XBMC for the last couple of months with no major issues.

The DVB-T streams i'm getting through TVHeadEnd are h264/AAC with a resolution of 720x576 about 2Mb/sec Video and 50Kb/sec Audio.

When watching TVHeadEnd through my appletv2 (via HTSP) the stream constantly skips, and feels as though the appletv2 struggles due to not enabling any kind of GPU offloading (running top on the appletv2 shows the appletv process peaking at 110%).

my existing ION-XBMC does use VDPAU for those streams and I can watch them stutter free, even with de-interlacing enabled.

Any ideas? is this a known issue?

BTW, in both systems (appletv2, ION) I can see continuity errors in the logs.

Hi there!
I have been using tvheadend and atv2's for a à long time without any problems.
I am running the nightlies of tvheadend( updated à week ago ).
I am allso running xbmc nightlies version fr.o.m. 22/7.
The only quirks i have encountered is that you must disable de-interlacing.

De-interlacing is disabled (I can see the interlaced lines ), and i'm also an avid fan of XBMC nighties for a long time...
Again, the video is h264 which should be hardware accelerated, which seems like it is not.

Any ideas?

[JeroenM]

Hmm. Not really.
I´ve been using tvheadend, DVB-T and xbmc for at least two years now without any problems.
You said you have alot of errors in your log.
Can you provide them please?

This is what i'm seeing in the log file when watching a recording or livetv:

Code:

[email protected], maybe [email protected] and zero ref frames. Someone needs to learn about encoding H264.

Is it fixable (mkvmerge and the likes)?
Will Andreas(Tvheadend) be able to know it hasnt got the correct flags?

Any reason why XBMC+VDPAU does work on this stream/recording?
