  There are a number of ports powered by Emscripten (https://github.com/Kagami/ffmpeg.js https://github.com/Kagami/ffmpeg.js) I wrote about some stuff here https://paul.kinlan.me/ffmpeg-ideas/ https://paul.kinlan.me/ffmpeg-ideas/ when building https://paulkinlan.github.io/deviceframe.es/ https://paulkinlan.github.io/deviceframe.es/ (I do a lot of screencasts and need a simple way to scale this out to other people that doesn't involve installing ffmpeg and scripting) EDIT and Note: Also I just saw your comment about videoconvert.js

    Do I understand it correctly that you want the users to do javascript ffmpeg processing on their android devices? I admit I have no idea what deviceframe is, so I'd also like to read some explanation on that too. Have you compared the speed of Android javascript ffmpeg vs PC native? What happens with the battery?

      Javascript and as soon as possible WebAssembly, as I understand it. I think mobile is a secondary consideration in this at this point. Considering it is connected to the internet archival efforts and simply ensuring the survival of numerous video/audio formats I imagine they are fine if it isn't efficient but simply effective at this point. Edit: on second thought, you might not be commenting on the VLC.js thing, I haven't read about the ffmpeg js stuff ;)

        Sadly, that answer is a completely missed conversation topic. I've asked about https://paulkinlan.github.io/deviceframe.es/ https://paulkinlan.github.io/deviceframe.es/

    do any of these ports allow playback of a video "in the browser" by chance?
