Hello - I’m having a recent problem with my OSMC media centre on a RPI3 over a wired ethernet connection. Some of my movies would play well from the start (if at the beginning of the movie) but when I tried to skip forward by 30 seconds or so, or move to a bookmark, the movie would basically freeze up and maybe move forward one frame every couple of seconds. It was severly stuttering with no audio. Also, the time on the bottom would show up as starting back at 0, even though the video frame was frozen at a later time. The same stuttering issue would happen if I started the movie where I left off last time - it would freeze right there with only minor movement forward.
This is a recent problem for these movies, which played well prior to approximately two weeks ago.
After some troubleshooting, I was able to determine the following:
3d movies with TrueHD seem to be the problem. This included Minions 3d, Secret Life of Pets 3d, and Enchanted Kingdom 3d. 3d Movies that used DTSHD were fine.
If I switched to the AC3 5.1 track on the above 3d movies, the movies would work correctly.
non-3d movies worked correctly, including movies using the TrueHD track. Example - Transformers Dark of the Moon.
The above 3d movie issue happened both with audio passthrough enabled and non-enabled.
When using the DTSHD and the TrueHD audio tracks, the on-screen information that provides the VQ and AQ showed the audio KB/s as between 4000 and 6000. When I selected the AC3 5.1 track, the KB/s would go down to approximately 600.
Since making this post on another forum with no help yet, I’ve tried additional troubleshooting. Here’s what I’ve found:
trying different cords doesn’t change anything. I’ve had issues before that were rectified by simply using a better cord. not this time.
i’ve noticed that when i advance by chapters, the video/audio works well. However, when i skip by 30 seconds, or to a bookmark, I am not so lucky.
When i advance by chapters, and view the information screen (with VQ and AQ), i notice that the VQ might go down to 0 for a split second but the movie keeps playing properly. The Video MB/s stays at around 35-50 MB/s. The VQ then slowly increases. If it apparently doesn’t increase fast enough, then “buffering” shows up and the picture is frozen while the VQ goes up to about 90-99%. Then the movie resumes normally. The only time the MB/s goes low is right when the movie resumes, at which time it goes to about 7 MB/s for a second, and then back up to about 35-50 MB/s. Based on this, the VQ buffering seems to actually be working here.
In contrast, when I skip by 30 seconds, however, the VQ quickly will go from 0% to 90-99% (not gradually like above). The video MB/s will also go down and stay at about 5-7 MB/s even with the VQ at 90-99%. As stated earlier, the movie stutters or is frozen at this time. I can only stop it and restart, or advance by a chapter to get the movie going again.
I hope this can shed some light on this issue. As stated previously, this is a new issue (started about 1.5 to 2 weeks ago now) and I didn’t have this issue previously with these movies.
Any Ideas? I’ve posted a log here for playing Secret Life of Pets 3d in TrueHD, which includes me skipping forward a number of times by 30 seconds to recreate the problem.
