Video Decoding Issue

[Shahid-Fahad]

I’m trying to decode a video encoded with the HEVC (H.265) codec using WebCodecs (via MediaBunny), but decoding fails.

reason: "undecodable_source_codec"

However, the same video can be decoded successfully in the browser on https://vidmix.app/, which also uses WebCodecs under the hood (see related Reddit post: https://www.reddit.com/r/webdev/comments/ua47e1/i_made_a_browserbased_free_video_editor/

This suggests that browser-level HEVC decoding via WebCodecs is possible, but I’m not sure what I’m missing in my implementation.

Are you on Firefox perchance?

Looks like you're on Linux. Could just be that decoding HEVC is not supported on Chrome on Linux. I doubt Vidmix has a way around that, maybe it falls back to a <video> element?
