dropped frames

[salingthehighseas]

Hello fellow Jellyfin users I am having some trouble with dropped frames and stuttering. This problem only happens when I am playing a movie through firefox web-browser on Desktop computer (Dell i7-4790, 16GB RAM, RX6600 Graphics Card) . Surprisingly when streaming on my Iphone 13 using the firefox mobile app I don't have any issues very smooth stream no strange dead or blocky pixels.   I do have hardware trans coding enabled as I have an HP-EliteDesk 800 G4 with an Intel i5-8500 (iGPU specs: Intel CoffeeLake-S GT2 [UHD Graphics 630] w/ 8GB of RAM.

I also have a secondary question. I have some media that that is video encoded as 4K HEVC SDR and audio is, AAC - 5.1 Default. All of my client side devices are unable to stream this codec. Is it possible to do a permanent re-encoding of this media?  

Thank you for any advice or guidance.

for permanent re-encoding see 6) here https://forum.jellyfin.org/t-from-disc-t...r-jellyfin

This is likely a client side issue. Nothing unusual about the codecs for the video. How is this PC connected to your network?

I suspected that your issue came from the H264 High, but coffee lake still has support for that codec. What OS is the client you're having issues with? I have a similar machine as my desktop and it's pretty poor at video playback in general, particularly through the browser. I haven't measured dropped frames but I avoid it at all costs if possible. If you're running Windows, you might try a better client like JMP and see how that performs.

In addition to the link already provided, we have an off-topic discussion around using ffmpeg CLI for re-encoding videos that has put out done good content. I need to get back to my development on a script I want to share for adaptive encoding, but there's a lot there already and you can ask any questions you have and I'll try (or somebody else will) to provide a good basic start where you can ask any follow-up questions you have.
