Plex web interface has ongoing stutter/jitter (not buffering) issues with HEVC/x265 content that is encoded at 23.976216 FPS.
Other files encoded at 23.976024 FPS do not have these issues. H264 files at either FPS do not suffer the same problem.
The stutter/jitter happens to the Web player and the PS4 app. The Android TV app does not have a problem. These are direct playing on all devices, not transcoding at all.
Any assistance would be greatly appreciated. Thank you.
And can you describe the stutter in more detail? (Consistent “low” framerate? Good playback but with a periodic skip?)
I’m assuming that these files were encoded using different workflows?
My guess is that the exact framerate is a mild red herring, and that some other difference is responsible. Perhaps fixed vs. variable framerates, audio track differences, muxing differences, etc.
Here is a short video showing the issue I am reporting. Audio plays fine, it’s only video related.
The only thing I could narrow down what differentiates the problematic files is the FPS differences:
23.976216 FPS - Has the problem
23.976024 FPS - Plays perfect
I am most of my testing on the local machine so I don’t think it’s network related. I have tried different browsers and other PCs with the same result.
I did not encode the files, but as I have mentioned. The only difference I can tell is the FPS. The same encoder and audio formats are used.
Hmmm… I heard no break in the audio. Are you just experiencing choppiness in the video drawing? I guess it may be FPS.
I’m not sure how you do testing on a local machine streaming through Plex. As I understand it, Plex and streaming, in general, is a network protocol, ergo it’s using a network. Now one might assume it should be a local, not network connection because the server and client are on the same machine but that’s assuming the OS is smart enough to realize it doesn’t need to use network reads. I’ve been tricked by this before under Windows.
share a sample of the file you just showed. just 30 seconds or 1 minute. obviously make sure you see the issue on your end in the sample file you create before sharing.
