I have a small problem with PVR. I’m really not sure is it OSMC related or tvheadend or KODI related, but a few symptoms tell me that is system issue.
While watching PVR (sattelite) every few seconds there are some short (1 second max) artifacts - something like errors in video stream, corrupted data etc. When error appears there is info in tvheadend logs, something like this:
2016-05-08 22:50:43.162 TS: Hot Bird 13E/11508V/CHANNELNAME: H264 @ #532 Continuity counter error (total 9)
I’ve google it and other users problems shows that it`s related with signal quality. I have something like this:
- SNR ~80%
- Strength ~70%
It’s not very high, so i thought signal is the issue, but when I connect to tvheadend and stream from other device (laptop, android phone) via LAN there is no problem. I made a few test:
- Watching TV via LAN and watching TV on OSMC simultaneously (same channel) - Problem occurs
- Watching TV via LAN and watching high bitrate video content from disk on OSMC simultaneously - Problem does not occur
- Watching TV via LAN and watching low bitrate video content from disk on OSMC simultaneously - Problem does not occur
- Watching TV via LAN while stress test in osmc ( sysbench --test=cpu --num-threads=4 --cpu-max-prime=20000 run ) - Problem does not occur
Does not occur means that does not occure or it`s very rare so its acceptable.
Other thing is that problem occurs only on HD high bitrate channels, on SD works without any issue.
I’m using:
- Latest OSMC
- Raspberry PI2
- Tvheadend GIT version compiled 2 months ago, but with repo version was the same.
- My tuner is Technisat SkyStar USB HD (DVB-S/S2)
Is anything I can do? Thank you in advance for your advice, and for readeng this quite long post !
