Rolling through on triage. Not clear that we have an actionable issue here yet, so leaving as is and answering questions that I can. > is this the reason why chrome works due to legal stuff? I had same problem on chrome until i turn off hardware acceleration then it start working which is kind of weird, my GPU is working fine so using GPU (assuming thats hw accel) should work. I large part, yes. Chrome ships 3rd party software that allows for decoding of certain codec profiles that platforms such as Windows do not support. Firefox does not use the same software due to licensing limitations, rather than technical ones, given my understanding. This is why certain hardware supported decoding pipelines may not work on Windows under chrome, but falling back to software does. --- It sounds to me like there are multiple problems here: - Some video does not play: because of the limitations discussed above, we will be unable to play these. We would like to, but it is in the hands of the platforms we run on. - Videos play, but with poor performance: my understanding is that this is what we're still trying to track down. Hardware acceleration may indeed help with performance in these cases. Based on comment 7 it appears you have hardware acceleration turned off for some features: `layers.acceleration.disabled` is set to false in your preferences. Could you navigate to Options -> General Tab -> Scroll to near the bottom and check if "Use recommended performance settings" is checked? --- As above, NSFW warning for the following links > https://chan.sankakucomplex.com/post/show/13923641 https://chan.sankakucomplex.com/post/show/16790609 The first of these is buggy for me on Windows. Playback stalls, or if I open the video directly it just skips to the end of the file. That page in general appears buggy under private browsing in the the page throws up "no video with supported format and mimetype found" -- but that's an issue for another bug.
