This is unreproducible without different steps to reproduce. Is anyone else you know able to reproduce this just by playing a video? Can you figure out what you have in common? Is it the same for all types of videos? Could it be that the video in question is in a specific video codec that your Linux distribution doesn't ship by default, and you need to install extra non-free packages?

I'm facing this same issue. I was able to load and watch the videos by re-encoding them to the VP9 format. The original video format was WebM and encoded with HEVC (I'm not entirely sure if it was HEVC and WebM. I will check again when I turn on my laptop). Also my friends couldnt load and watch the video in their side as well.

This is good information, thanks! What's your build info? You can find it by opening User Settings > pressing on the build info at the bottom-left.

Binary: stable build 508 (3250c73), 2026-06-06 21:26:08 UTC, Electron 39.2.7, Linux 7.1.9-arch1-2 (x64), desktop stable 0.0.8 Web: stable build 508 (3250c73), 2026-06-06 21:26:08 UTC, Chrome 151.0.0.0, Linux (x86) I was wrong in my last comment. Looks like the problem is in the backend side. Because its sending only sound. Not the screen. I couldnt upload reproduce video to GitHub due to file size limit. So i uploaded it to Fluxer. But looks like theres something different. https://fluxerusercontent.com/attachments/1491534074373863039/1542589300439257088/2026-08-27_18-35-30.mp4

I recorded above video. then compressed it via online tools in the internet. then i uploaded it to fluxer, and it works! probably the compress site converted it to h264 (baseline version) and avc1, so it works now. the uncompressed original video ffprobe output:

Thanks for that. It does not appear to be a backend problem, from what I can tell. The CDN file is valid HEVC Main (hev1) video with Opus audio and FFmpeg successfully decoded its picture. The backend did not strip the video track. Electron 42 embeds Chromium 148. Your exact Radeon 610M is explicitly denied VA-API because Chromium found that initialisation reliably crashes despite vainfo advertising HEVC support. Forcing the GPU path would therefore be unsafe [1][2]. I can improve how the client presents this on canary, and provide a way to download it instead, since there is no way it can be played inside of Fluxer without transcoding it. Fluxer doesn't do any transcoding on the server, and doing it on the client would be costly. PS: You should be using the canary client for bug reporting (#736), but that wouldn't change anything in this case, but you would avoid many other bugs. If you are married to Flatpak, there's [3] until we create our own Flatpak remote for canary (soon).

hmm.. i see. i just checked to see if it works on my phone, and it does. sorry for my wrong guess. "Looks like the problem is in the backend side." I said, because my friends were having the same issue.

Sorry for that. I downloaded fluxer-canary-bin package from AUR. I'll do it next time when reporting bugs.
