For me OpenELEC-RPi.arm-Rbej-Version-Gotham-Branch-c01c97d9d1 only has a 25% success rate with TVHeadend. Most of the time I get a black screen (quick flash of the picture if I stop the stream) and when it works the aspect ratio is wrong.

For Gotham users: do you have time shift option enabled in the Tvheadend server settings?

I don't need time shifting so I had not touched Tvheadend time shift settings.
It has default temp file path left empty.

As I strugled with the same black screen problem as the others here, I decided to try time shifting.

I set default time shift temp file path to my external usb hd and clicked time shifting on.

Live Tv started working better. All the sd channels were showing. Aspectratio was still wrong but overal usability is now allmost perfect.

I've been following this thread for some time now, waiting for a fix. But Kives gave me the clue that resulted in both SD and HDTV live from TVHeadend in OpenElec 2.99.5. Only problem now is audio sync.

The only thing I did was upgrade to TVHeadend beta from the beta repo. http://apt.tvheadend.org/beta Now running build 3.3.517~ga69f4e6~precise.

After that I enabled timeshifting.

Still not perfect but this thing is great. I love XBMC on the Pi! Big Grin

Hi Rbej - thank you very much for all your development efforts within the RPi\XBMC community, unfortunately your recent Gotham build still does not resolve the Live TV black screen issue for me, there is a slight improvement when I upgrade to a TVHeadend beta build and enable the timeshift feature but sadly Live TV on the RPi is still not stable enough for daily family use ...

Configuration >> Recording >> Timeshift

If it's not there, you might have to update to more recent version. Current beta version has the timeshift tab.

No need to change anything in XBMC.

Darn, with timeshift enabled (and latest rbej build) I'm getting 100% success rate with sd h264 & aac latm dvb-t. (edit: with no timeshift I'm getting misc results, I would say 25-40% success rate).

Aspect ratio is wrong, I haven't looked in the ts file, maybe it is correct and the pixel ratio is wrong anyway an option in tvheadend to manually force an aspect ratio would be great.
I'll have to get another look at this but I think only one audio channel is recognize (mono instead of stereo).

Great work, tvheadend is the easiest pvr backend to set and update (and manually compile) and now very useable with the Raspberry Pi.
Kudos to all the developers.

Morning,
Last night i tried latest Rbej build (Gotham) on a 256 MB raspberry connecting to tvheadend beta (latest build) installed on a linux server and with timeshift enabled.
SD channels (Mpeg2) works great, HD channels (H.264) are a little slow, audio out of sync and it seems like video can't follow audio streams, slowing down and then accelerating...
Default settings, no overclock, only codec license keys added on config.txt .
One crash occured when i was browsing the menu with a SD channel on background.
Unfortunatley i couldn't save log files.
I can retry tonight.
thank you to all developers trying to fix this issue.

The last issue I've got with tvheadend is wrong aspect ratio recognition on the Raspberry Pi (on other platforms it's fine).

If anyone else suffers from this issue please post here to let the developers be aware (if they aren't already).
(already found one user confirming this here).
Consider posting relevent infomation about your issue.

My issue is with dvb-t service h264 codec, 720x576 resolution that should recognize as 5:4 but does recognize as 1:1.
Here a full 90MB ts dump (captured with mumudvb) https://dl.dropboxusercontent.com/u/6902...MC/test.ts

The following build seems to have resolved my Live TV black screen and stability issues, based on a TVHeadend\Ubuntu backend system streaming UK Freesat MPEG2 content to my 512Mb RPi over wifi. It is by far the most reliable build I have used for Live TV, kudos to you Rbej keep up the great work.

I have the latest stable tvheadend installation (3.4). Have timeshift enabled.

Installed the rbej Frodo 12.2 branch. This works great with the SD channels, but the HD channels the auto is out of sync.

No change with the aspect ratio issue.

Wow! - a lot has happened since I last checked in.

Tried the latest rbej build with timeshift enabled.

Black screens seems a thing of the past Smile

- although aspect ratio still seems wrong.

However, I can confirm that audio and video sync gradually is lost - there doesn't appear to be any definite circumstance.

I watched 1 hour with minimal sync loss one evening , then another program that lost sync within minutes?

Do other people experience this?

Thanks very much everybody for looking into these bugs - I am on the verge of dumping WMC.
