Dreambox dm7020hd: Streaming from OpenPli 4 (to XBMC or PC using VLC)

31 July 2014 - 07:49

See also post : http://openpli.org/f...nigmavu-client/

 

Currently the streaming just stops after a undefined period of time, when the stream is stopped in VLC and (re-)opened agian, the busy animation becomes active on the TV. This takes about 15 mins. Then it recovers and the TV zaps (when running from 2 tuners) to the channel that was streaming and the streaming on the PC resumes as well. The following messages are taken from "/var/log/messages" and this seems to be why the stream stops.

The time on the Dreambox LCD is 09:37, the Dreambox is always the same 15mins = 900secs busy. I didn't found any triggers for this. When it recovers at 09:51 no messages appear in the "/var/log/messages" log. After 2 mins the following appears in the log so thats just some normal messages.
 
  Jul 27 09:53:54 dm7020hd user.info kernel: [ 5039.699000] bcm4506: signal_strength -196.68dbm

During the busy period of the Dreambox, the OpenWebif, remote control nor buttons are not responding. You can still login to the Dreambox using SSH. I did some tracing of the engina2 application, but the only messages comming out are;
 
  [eFilePushThreadRecorder] Warning: All write buffers busy
  [eDVBRecordFileThread] cancelling
  [eDVBRecordStreamThread] failed to cancel, killing all waiting IO
  [eDVBRecordFileThread] poll: aio_return returned failure: Value too large for defined data type
  [eDVBRecordFileThread] poll: aio_return returned failure: Value too large for defined data type
  [eDVBRecordFileThread] poll: aio_return returned failure: Value too large for defined data type
  [eDVBRecordFileThread] Waiting for I/O to complete
 
These messages repeat themselfs, but when the enigma2 application is BUSY no messages are being outputed. But i think this is releated to the CCcam share slowly or not responding sometimes.  
 
My Dreambox has two S2 tuners, and there is no difference in behaviour between running the stream from the same tuner (one tunner active (ZAP)), or running from active 2 tuners with different channels.
 
I think that XBMC vuplus add-on has a more aggresive connection strategy to which results in sometimes hanging up the Dreambox completly. 
 
 
 
Any ideas how to find and/or solve the problem ?

How to build OpenPli 3.0

14 July 2014 - 19:08

Hi all, 

 

i want to try to build OpenPli 3.0 for my dm7020hd, this is due current problems with streaming channels to XBMC engina client. Under OpenPli 3.0 it worked perfectly.

 

I tried first to build the OpenPli 4.0 on Ubuntu 14.04 i386 (used this link http://users.telenet...npliubuntu.html), this failed miserably. due to problems with invalid checksums, so therefore I don't want to invest in this route any more. 

 

So my question is can anyone help me setup my build environment and preferably for OpenPli 3.0

 

Any help would be appreciated,

problem OpenPLI 4.0 Streaming to XBMC enigma/vu+ client

5 July 2014 - 15:54

Hi all,

 

I've installed the openpli 4.0 on my dm7020hd but now a i've problems with my XBMC enigma/vu+ client. It starts out just fine after some time (+/- 30 mins.) it just stops streaming, on the dm7020hd the animation is turning on the screen, there still the channel that was selected is still playing, but it doesn't give any reaction on the keys or remote. i logged in via ssh and killed the engina2 application, which restarted directly. Then every thing comes back normal including the streaming to the XBMC client. 

 

This behaviour is introduced by the openpli 4.0, i just want to go back to 3.0 but that files for this release have been removed. I read that no stable releases are released, i my opinion this is a mistake, even so that when flashed a image you can't select an release to upgrade too. 

 

This is a really annoying problem the XBMC is in the bedroom, and we cannot see any TV channels with out this disruption. 

 

Can help me with this.... 

 

Regard,

 

Marc
