MP4 file Video Rendering Issues - Chrome Browser

edited April 23 in Plex Web App

I have an mp4 file that does not play properly using Plex Web Player 3.41.2 on Chrome Version 66.0.3359.117 (Official Build) (64-bit)/ Windows 10.
The first few seconds play OK, then the video becomes torn / blocky for the remainder of the file. The audio Is OK.

The same problem also occurs using app.plex.tv version 3.47.1. I have disabled all Chrome Extensions and tried using Incognito mode with the same problem.

It does play fine on Roku , Windows media Player and Plex via MS Edge on the same Windows 10 PC. So, it is somewhat similar to this other thread < https://forums.plex.tv/discussion/314041/>, but is specific to one particular file.

However, I can get the file to play properly on Chrome if I disable Direct Stream. I also noted that this file has mov.text streams. If enabled, the subtitles continue rendering properly even though the primary video is stuck in the torn/blocky display.

If needed, I can provide a 5 second version of the problematic file. It ends just as the rendering stalls and doesn't get to the torn / blocky stage.

The File Info and Debug log are for the full version of the file.

Debug Log - this seems to be the interesting part where things fall apart….
