There is anyway I can convert a MP4 file to WebM at the runtime?
I want to pick a file (FileChooser) and if it's MP4 I want to convert to WebM.
Is that even possible? Or using JavaScript somehow?
Develop games in your browser. Powerful, performant & highly capable.
Transcoding media files is a specialist task that isn't really something a game engine would normally do. There are free web services out there that can already transcode media files for you.
Oh ok, thank you <3
