jolumatro 0 Posted February 25 Share Posted February 25 Hello. I have observed an issue in the Web player, both in Edge and Chrome, Server version 4.8.1.0 When switching subtitles on (SRT and MOV_TEXT) the movie plays with jittering in full screen mode. The jitter coincides with the appearance of a new subtitle, most times. If the video is 720p, it does jitter like changing aspect ratio (And actually switching Aspect Ratio from auto to any other option fixes it temporarily, until you stop the video. Next time you play it, the issue happens again) If the video is SD, it flashes a frame from earlier very quick (Like framebuffer remains) Could this be a bug?

Luke 37068 Posted February 25 Share Posted February 25 Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks! Link to comment Share on other sites More sharing options...
jolumatro 0 Posted February 25 Author Share Posted February 25 (edited) Thank you, I have recorded both scenarios from my phone. I have also attached the server log from right now, last actions are what we see in the clips (First 720p, then SD) In the 720p is less noticeable (12, 14, 20 seconds) how the borders jitter (like readjusting aspect ratio), but the SD case is more noticeable. 720p uses external SRT, SD uses embedded MOV_TEXT Appreciate it! 720p example.mp4 SD Example.mp4 embyserver.txt Edited February 25 by jolumatro Link to comment Share on other sites More sharing options...
Luke 37068 Posted February 25 Share Posted February 25 Interesting, never seen that before. Can you provide a sample video for testing? Link to comment Share on other sites More sharing options...
jolumatro 0 Posted February 25 Author Share Posted February 25 Just as a test I enabled remuxing for the user, issue still happens. Also, issue does not happen on Android app. Thank you Link to comment Share on other sites More sharing options...
jolumatro 0 Posted February 25 Author Share Posted February 25 (edited) Sure, I just cut one chapter from the SD file. It does keep the MOV_TEXT subtitles when downloaded.

Luke 37068 Posted February 25 Share Posted February 25 OK just to make sure, did you verify the issue occurs with the smaller sample? Link to comment Share on other sites More sharing options...
jolumatro 0 Posted February 25 Author Share Posted February 25 I just did, and it does not happen. Subtitles still work outside Emby, but inside emby they don't show, although they are detected as track. I can provide the whole episode untouched (227 MB)but its over the forum limit. Any alternative way I can provide it? Thank you Link to comment Share on other sites More sharing options...
jolumatro 0 Posted February 25 Author Share Posted February 25 Another interesting test that starts to point in another direction: Used Chrome on a separate laptop, simulated remote access via VPN, and played both media, issue does not happen. I am thinking this has something to do with the GPU or GPU driver in this case. They are both AMD but really distant generations (Affected one is Ryzen 7 3750H, laptop working fine is AMD A6) Truth is, the 3750H already did weird stuff every now and then when playing video on the browser, only it was never as annoying as this case was. I am going to start looking in that direction as well. Link to comment Share on other sites More sharing options...
jolumatro 0 Posted February 25 Author Share Posted February 25 (edited) After updating AMD drivers, the issue is still there, but even worse. In addition to frames flashing, I also get green borders that may stay or go away in seconds. Finally fixed both issues by using GitHub - RedDot-3ND7355/MPO-GPU-FIX: MPO Fix for 5000/6000/7000 AMD GPUs & RTX 3000/GTX 1600 Edited February 25 by jolumatro Link to comment Share on other sites More sharing options...

jolumatro 0 Posted February 26 Author Share Posted February 26 Hello Luke, Do you still want the upload? As I stated on my last reply, issue was on the Ryzen/GPU side of things, nothing wrong with Emby. Thank you! Link to comment Share on other sites More sharing options...
Luke 37068 Posted February 26 Share Posted February 26 If you've solved it then that's ok. Thanks for the update ! 1 Link to comment Share on other sites More sharing options...
