Found a problem with PVR? Report it on Trac, under "PVR - core components". Please attach the full debug log.

This is almost certainly NOT a bug in the firmware though broadcom have been involved. It looks more like a simple state machine/AV controller bug in OMXplayer. I'm currently doing a bit of digging myself.

I talked to gimli, he said that he didn't found a solution for this problem, maybe you too together could figure it out?

adamsutton: doesn't sound good! is it something we should push with the XBMC team working on the RPi port instead or is there a workaround you can put in TVH?

@spylex gimli is the xbmc team working on rpi. He's thus far been unable to find a complete solution, though we may have some minor progress. But nothing concrete yet.

Just got my RPi, running TVH 3.2.18 on my unRAID server, i assume even the latest Raspmc won't show me TV unless i use the workarounds mentioned in the previous pages. Thanks for the prompt response adamsutton Smile

I have my Pi streaming using Tvheadend on Mpeg2 streams (SD not HD). With the option choices described below it works first time. By that I mean I can enter live TV and select a channel, if I try to change the channel I see only a black screen and I need to reboot. I'm not sure which option or combination of options is responsible. When I have time I'll iterate through and find out. The aspect ratio problem remains.

I know people already have this working first time. But until I made these changes I was unable to stream any TV. Ie I saw a black screen on the first channel selection. Some might find this post helpful if they're in the same position. Entering the HTSP stream as a source workaround didn't work for me either.

System: Openelec 2.99.1 on 256MB Pi Model B streaming from Tvheadend 3.2.18~g40a8920~precise.

Menu options (import all data and set up what should be correctly then go and change the options after):

Synchronize channel groups with backends OFF
Imports channel groups from the backend OFF
Always use the channel order from the backend(s) OFF
Use backend channels numbers (only works with 1 enabled PVR add-on) OFF

Do not store the EPG in the database ON

I tried using the htsp:// method in sources.xml and I still get channels displaying in 4:3. However if I set up a http:// link directly to a channel as a strm file there is no problem. This leads me to think that it's not necessarily a problem with the TVHeadend addon but with the XBMC implementation of HTSP in the way it calls OMXPlayer.
It seems a lot of people are having the same issue - these forum threads are getting a lot of views. I've added my logs to the ticket on trac:
trac.xbmc.org/ticket/13783#comment:7
I hope the devs show this bug some love soon.

With the newest build from this site:
http://openelec.thestateofme.com/r13143.img.zip

Live-TV is working for me (ok the channel switching takes more time then on the atv2, but it is ok).

Even HD-Channels are working.

The only thing which is not working is the aspect ratio issue.

Could it be possible that the width and height is mixed up? On 16:9 HD channels i get a width of 720 pixel and on 4:3 channels the picture has the aspect ratio 3:3. Maybe i'm wrong but this is what i see.

[EDIT]
OK the private german hd channels aren't working for, everything else looks good.

@gimli did you have any luck with this since 12.0 final came out? Smile

Using raspbmc installation, streaming from tvheadend 3.2.18 (running on a separate i5 debian box on my LAN) has not worked since I upgraded from RC2 to RC3. Using 12.0 it still doesn't work.

More specifically, I'm streaming DVB-S2 (FreeSat, plus some other stuff, ahem) from tvheadend to my 2 pi units (1x512MB, 1x256MB, both with MPEG-2 and VC-1 licenses installed correctly). Under RC2, I had problems with some SD channels on the pi, but all HD channels worked flawlessly. Since upgrading, I cannot watch -any- channels.

The same channels (both SD and HD) work perfectly on a number of other XBMC systems (Android phone/tablet, laptop, etc), which are running a mix of RC2, RC3 and 12.0 final, so I -think- we can rule out an XBMC-wide problem. Moreover, recordings from any channel work perfectly on the pi, so it isn't power-related or performance-related or memory-related (playing an HD recording from tvheadend uses about 30MB of memory according to the screen output when logging is enabled).

What I see happening with live TV on the pi, however, is the available memory (shown when logging is enabled) dropping continually until it reaches about 17MB (starting from 400MB, dropping 5-10MB every 2 seconds) and then XBMC restarts (presumably because it fails to allocate additional memory and crashes / exits).

There is nothing in "xbmc.log" to indicate that XBMC failed to allocate memory, however. In fact, there is nothing -at-all- in the log from 30s after starting the stream until it crashes / exits - here's the last few entries from the log:

and it crashed / exited (due to lack of memory) some 3 minutes after this last entry.

It would appear that omxplayer isn't being initialised / told to start playing the stream properly. What I'm not clear on is why there is a difference between live TV and recorded TV. (I record in TS format, so in theory the recording and the live stream should be identical to XBMC, shouldn't they?)

[EDIT]
I've now tried OpenElec (r13238 and a custom build by rbej) - I've got SD channels -almost- working (oddly only some of the channels can be used to start playback, but once it works, all SD channels can be switched to), but no HD channels will play.

@Neil i have also tested openELEC now with similar results as yourself.

I have also observed something unexpected (and that I haven't seen reported previously)... When attempting to play a live HD channel, I get black screen as expected. Pressing enter brings up the playback / audio / video controls (again, as expected). However, the audio stream type is blank (i.e. no indication of MPEG-2 audio or similar), and audio streams is listed as "0.0" (instead of 2.0 or 5.1 as I would expect).

Does anyone else see this? I have been looking into whether the problem was a regression in the tvheadend plugin (see #166 here), but @opdenkamp believes the problem lies in omxplayer, and so that is where I intend to focus my efforts (for whatever they are worth).

Does anyone else experience the audio streams for live HD channels being misreported in this manner?
