I’ve been using the latest ng build on my X96 Mini for a couple months now.
All was well until earlier this week when I encountered 2 separate media files that would not play smoothly, in differing ways.
One of the media files was a 1080i film, it was unwatchable, 80% of the frames were getting dropped. I tried another 1080i film and the problem was the same… so there appears to be an issue with 1080i media for some reason.
The other problematic file was not as severe. stuttering audio and occasionally dropping a bunch of frames every 10 seconds.
The codecs were nothing unusual though, blu-ray quality 1080p avc and stereo pcm s16le audio, the same format as 90% of my media files but for some reason this particular file had issues.
I’ll try the latest non-ng build to see if these issues present themselves.
Edit:
1080p VC1 content does not play correctly either. Loads of skipped frames, but they’re not counted by Kodi’s debug overlay.
