v17 pixelation and audio loss
#1
Hi,

I have a HD Homerun and an Intel NUC i7-5557U running Ubuntu 16.04.2 with Kodi 2:17.1~git20170320.2031-final-0xenial.

When watching live or playback recordings I get random pixelation of the image and audio corruption. I've tried a few tweaks but nothing helps.

The HDHomeRun Add-On will play without these issues. It will occasionally pause but video and audio resume without any loss of content.

Where can I start to help debug this issue? Is my hardware not up to spec? What logs can I provide?

Kind regards,
Tom

No Debug Log no issue!

Can you reproduce with a recording?

The file seems broken :-(

Hmmm... I'll do another recording and repeat the procedure (send the logs from the file play with mythtv-backend disabled)...stay tuned!

I've recorded some live TV this evening but it looks like this file is also broken. What keeps breaking my recording files?

Can you try vdr instead of mythv?

Does vdr work with HD Homerun?

apt-get installed vdr 2.2.0-5build1 but I have no idea about this program. It may take some time to get it working. The service failed to start after install.

Am I to understand that MythTV may be the cause of the corruption?

That's what we are going to find out.

Also pixelation here: http://solidrun.maltegrosse.de/~fritsch/..._h264-2.ts ?

Hi Fritsch,

I downloaded and played the file 1080i50_h264-2.ts. Absolutely no problems with pixelation or audio. Did you want me to capture a log of that?

Looks like the MythTV backend is the issue. Correct?

Hi Fritsch,

I've been trying with tvheadend - recording is better but I'm still getting some pixelation. Audio seems to stay reasonably clear. Still not 100% clear for either thing.
