Slide video sometimes restarts the video
I have several slides with slide video blocks, each of which displays a different MP4 video file. The project is hosted on a web server, not an LMS. I noticed that when I updated the videos, and re-uploaded the project to the web server, the videos would often spontaneously restart anywhere from 3 to 10 seconds into the video. The problem was more pronounced after I cleared my browser (Edge) cache, and the restart problem seemed to go away after I ran the project a few times. This led me to believe it was related to how the slide video block cached or retrieved the video.
My hosting service provides a Content Delivery System (CDN) service, which I enabled to see if it would help the problem. The problem went away completely. While the CDN solved the problem, this issue has not surfaced before. Something has changed in the way that slide video requests byte ranges for video, or something related to caching or video retrieval. Developers should not require access to a CDN service to get their project videos to play without spontaneously restarting.
My request is that the code for slide video playback be improved such that restarts do not happen, and a CDN is not required to avoid video restarts.
Also please reference Adobe Case ADB-45552178-C2J3, which is where I reported this issue. Since the CDN solved the current issue, the case was closed.
