Bug #3651
Dropped frames in Kodi
0%
Description
I'm getting a lot of dropped frames when playing Live TV in Kodi. The debug log in TVHeadend shows nothing special.
The other relevant logs can be seen in this post: http://forum.kodi.tv/showthread.php?tid=231955&pid=2288583#pid2288583 .
It happens both with hardware acceleration (VAAPI) enabled and disabled.
journalctl -u tvheadend -S "today" only shows entries like:

I also just upgraded to the latest git version.

No, all I see is:
2016-03-22 17:48:39.510 mpegts: 11739V in Astra 3 - tuning on TurboSight TBS 6981 DVBS/S2 frontend : DVB-S #0

And nothing else, even with debugging enabled.

Updated by Have you tried vlc with this URL: 'vlc http://TVH_IP:9981/playlist?profile=matroska' ? It uses almost same code as kodi plugin, so if it works, your kodi is somewhat broken.

I used the following link:
http://192.168.3.1:9981/play/stream/channel/1a6acb1de72a9b14f2a4593c718f8a74?title=1%20%3A%20NPO1%20HD
Seems to work fine in VLC. No dropped frames.
I thought it might have been an issue with Kodi after opening this issue. Previous versions of Kodi work fine.
I'll try to find the issue at Kodi. Thanks

The test should use matroska media container (?profile=matroska or add &profile=matroska to the end of your URL). If you use 'mpegts passthrough', it might not show some bugs.

Seems this was a bug with Kodi: https://github.com/kodi-pvr/pvr.hts/issues/209
I haven't tested it yet but it should be fixed now.
Thanks.
