I made a Webassembly Videoplayer with Pure Data / Ofelia / Emscripten. It is possible to drag and drop a video file or to load it with a file browser.

@Jona Well done! Very cool... I had to try it and why not sharing a demo!

@EEight Mmmmm....!.... palms outside.....

@Jona Cool!

@EEight thanks for posting the video. It seems I have to use a larger audio buffer size, because your sound is crackling(?) sometimes...

My only issue is (so far), that it would be really great to keep the last frame until seeking the frame of a new position is finished (instead of having a black frame for that time). I already tried to solve that, but without success... My guess is, that I need to read the video.onseeking event or video network status from Pure Data / Ofelia for that (so that I can update the video only if the information is already there...). For that I need to change some of the ofxEmscripten source code:
https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/seeking_event
https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/networkState
https://github.com/openframeworks/openFrameworks/blob/master/addons/ofxEmscripten/src/ofxEmscriptenVideoPlayer.cpp
https://github.com/openframeworks/openFrameworks/blob/master/addons/ofxEmscripten/libs/html5video/lib/emscripten/library_html5video.js
I actually already changed the code for drag and drop and the file browser (and some other issues): https://github.com/Jonathhhan/Pure-Data-Ofelia-Emscripten/blob/main/videoPlayer/library_html5video.js

I solved the issue with not showing the last frame while searching a new frame.
