Video Playback Pauses

[Nisten 15]

When it pauses, it just stops playback (pressing play has no effect) but doesn't exit out of the video and doesn't show any errors or loading wheels but I still see the playback timer counting up when I check streaming progress in the server dashboard. It doesn't appear to be any rhyme or reason why this happens. I usually have to resort to playing the file outside of Emby via an external player in order to finish playback or move to a part in the video that plays fine via the Web app (if it pauses early on). Since i'm able to play the same file through an external player on the same OS without the pausing, it doesn't seem to be an issue with the video file(s) itself

What Roku model is this?  Wondering why hevc is not supported.

&VideoCodec=h264,mpeg2video&AudioCodec=ac3,aac,mp2,mp3,flac,vorbis,lpcm

&TranscodeReasons=VideoCodecNotSupported

Do you get the same result with Throttling disabled? 

With Hardware Acceleration disabled?

@Nisten What do "stats for nerds" show on the Roku when playing that file? That will give us the exact model number.

The pauses might be due to signal strength. The Roku when playing directly cannot work through some decoding errors. If the signal is corrupt coming through the antenna it might cause the Roku to drop the ball. If this is transcoding through ffmpeg like you are doing this should work. But it might be hardware acceleration is causing the hang. The Roku may not like what is happening even though other plays may. The Roku when it encounters frame drop will not recover it just hangs. The Roku turns everything into 60 frames per second progressive video. This is why you sometimes see weird judder as the screen pans left and right during movement. You can have the Roku auto adjust framerate to the video but that will cause black screens while the sync adjusts for a second or two. It is what it is in that regard.

But the signal strength issue might be all this is if you are playing off aerial.

4210X but this is happening through Windows Web Playback via MS Edge but I did try disabling throttling & HW acceleration with no effect (attached a new server log though)

Haven't tried playing this on Roku, issue is happening through Windows Web Playback via MS Edge (attached a new server log though)

Did it direct play in Edge? Microsoft has an open defect related to hevc stuttering in Edge.

It sort of doesn't. Like it won't stutter, but playback will just abruptly stop. For the 1st video/episode I encountered this on, I had to skip ahead a couple of minutes then it played fine for about 30 minutes before it abruptly stops; However the stopping points always seem to be same timestamps, forcing it to transcode has no effect

What do you mean by "it sort of doesn't" ?

I mean it doesn't stutter but parts of the video halts playback, like I know a specific episode that stops playback after only a couple of seconds of pressing play but if I drag the playback slider a few minutes ahead then it'll play just fine until it reaches another video segment it doesn't like but I can play the same episode(s) direct (internally though the OS like via Windows "Movies & TV" app) with no playback issues

Looks like there's two flags they referenced disabling/enabling but no such luck. Thanks for the community/forum info though. I'll just use another web browser or play direct internally for the time being

edge://flags/#d3d11-video-decoder [No longer available]

edge://flags/#disable-accelerated-video-decode
