So my friend decided to watch a movie tonight from my server. He’s watched several before and they’ve all worked fine. The movie is an x.264 1080p mkv being streamed to a PS4 with a transcode quality of 720p 4mbps.
My internet speed is 80/20 and his is 24/4 so connection speed is more than enough and we’ve both done speed tests which came back fine.
The movie starts off playing fine and the transcoder begins its work and is normally working about 4x then gets throttled.
How ever after a certain while the transcoder just seems to sit at throttled and doesn’t transcode the rest of the movie so eventually the stream catches up to the transcode and results in playback stopping.
It has me totally clueless as to why it’s started doing this. I’m running the PMS on my QNAP x53B and using the hardware transcode version. I have extracted the logs but unsure which ones to upload. If someone can suggest I’ll upload them to provide more info.
It could be a corrupt file.
Try the same settings on your side and see if you can get past the spot he was at.
Have the client try other files to see if they hit the same issue.

Thanks for the tips.
I tested the same movie on my device using the quality setting 4mbps but instead of remote it was over local LAN. I was able to get past where he was but I only started it a few minutes before where he was (45 mins).
However after 10 mins on my device via local LAN I got exactly the same issue. The stream catches up to the transcode buffer and doesn’t seem to transcode the rest saying buffering and the transcode is throttled. Normally the transcode buffer is a good 3-4% ahead of the stream. It starts off that way on here but then the stream catches up and transcoder doesn’t kick back in.
Other files seem to work absolutely fine and he’s watched 4 or 5 other films without issue this week.
I’ve been reading your logs. I think this is a bug.
Your running the hardware beta and this movie is using vaaip
“DEBUG - TPU: hardware transcoding: using hardware decode accelerator vaapi”
Try turning off hardware support and see if you have the sloth mode problem on this build. If so please try upgrading to 1.5.2 (without hardware) and see if it now works.
You might have found a bug using hardware transcoding of mpegts files.
I’ve tried several other versions of this film 1080p, 720p and they all do exact same so don’t know if they’ve all been encoded with from the same original source.
I’ll give your suggestion a try and see if it still does it without hardware transcoding enabled.

Was this a movie you recorded with Plex DVR?
Ok disabled hardware transcoding on the beta and the file played fine so looks like a bug in the hardware transcoding as you mentioned.
Is there anyway to get this flagged by plex and onto a tracker?
