Most projects work fine in emscripten but no way to get the video player to work, I try a lot of things but nothing works. I changed the SDK version, I used nightly compilation. The videoGrabberExample works, the sounds too, strangely there is only the video function which does not work. I would like to make interactive video tutorials as part of the courses I give…
Does someone have an idea?
beautiful day!

I don’t know javascript, but I know how to read the video player on Arturo’s site
https://arturocastro.net/files/of-emscripten/videoPlayerExample/
Other examples work fine…
I probably should have specified that the compilation is carried out without problem, but it is the opening which does not work!
yé!

Hmm - pinging @Jona for this one!
Will see if I can recreate here. Have you tried running it in different browsers?
@theo @bernard_Del its a known issue, that appeared with a pr like a month ago (just no idea how to solve it): ofVideoPlayer and Emscripten · Issue #7377 · openframeworks/openFrameworks · GitHub
thank @Jona you but when you say
“I use ofSoundStream (before loading video player) in ofSetup” do you do this or is it another way?
//--------------------------------------------------------------
void ofApp::setup(){
ofSoundStream();
ofBackground(60,60,60);
fingerMovie.load("movies/fingers.mp4");
fingerMovie.setLoopState(OF_LOOP_NORMAL);
fingerMovie.play();
}
because it doesn’t work for me
Not really sure, but I think I also had to include ofSoundStream.h in ofApp.h.
ok i have to give up for today…
I added
#include "ofSoundStream.h" in ofApp.h.`
and in ofApp.cpp
void ofApp::setup(){
ofSoundStream();
but no video.
always the same message in the firefox console:
Uncaught ReferenceError: allocate is not defined

thank you @Jona , we will have tried!
the rest in the next episode
here’s a kind of tacky solution - just replace this file in libs/openFrameworks/sound/
I’ll check that tomorrow morning, great. i will tell you what happens
Merci pour le suivi !
Hello,
Great @theo, it works by changing the file ofSoundStream.cpp
Have a nice day and thank you for your help @dimitre , @Jona !
Bernard
Great! Going to merge this hack fix for now and we can getter a better solution going.
