I’ve found that there are delay issues when attempting to load an mp4 via an input tag, such as this:
After selecting an mp4 file, the ’loadeddata’ and ‘loadedmetadata’ events do not occur immediately (which they should). It takes up to 5-10 seconds to fire the events. Perhaps this may shed some light on what’s happening;
video.addEventListener('loadeddata', video_data);
video.addEventListener('loadedmetadata', video_meta);
