I’ve been investigating this issue for 2 days now. I discovered it by accident yesterday while testing the latest server version on my QA server through a web browser. Here’s what i’ve found so far… Playback goes into a spinning state in the browser and shows “Buffering” on the server dashboard a…

Is this one of the failing file sessions?

No. Not sure why that would be showing up as I haven’t tried to play that media today

@Jacob_Allen Somebody did :slight_smile: Can you check that video please and see what you get ?

Just played that particular media. No issues at all

Ok… so that one was apparently they started playback then changed their mind. Oh well Regarding PMS versions - 1.24.5.5173 is PRE transcoder update 1.24.5.5286 is POST transcoder update. 1.24.5.5319 is contains FIXES for the transcoder update Point 5 - not possible for MKV to be direct playe…

With my direct play question for mkv i was specifically referencing playback via browser For me, my Transcoder default throttle buffer is the default (60s). if i change it to 30s/120s/150s, it buffers at the same timestamp. This is with direct stream on both video and audio (AAC). If i change to a …

I don’t know of any browsers which accept MKV files. They were all designed around MP4 (before MKV was a thing). MP4 files permit being “optimized for streaming” (geometry information relocated to the front of the file) which is why they’re so popular for embedded videos in web pages. This is co…

I didn’t particularly care about the mkv direct playing thing, was just a curiousity :slight_smile: Is it the same amount across all test cases using different conditions (audio or video) ? hmm, for the issue, only thing i can say for sure right now as i said previously, was that in Edge it was …

That does stink of a missing Key frame. There’s space to be saved by trimming key frames but there is also a healthy cost when streaming and that key frame gets damaged or droped. You’re stuck until the next one – which is a long time. I have a few fires to put out here today but will see what I…
