Steps to reproduce

In Chrome/Firefox/Safari when playing an video or audio file using the HTML5 elements, if the source file’s metadata is not found at the beginning of the file, and the server’s response headers advertise support for byte range requests, Chrome/Firefox/Safari request the end of the file and look for the metadata there. If found at the end of the file, they can start playback without downloading the entire file first.

In IE/Edge, if the metadata is not found at the beginning of the file, the browser just keeps downloading the entire file until it reaches the end, and then it starts playing. If the file is 500 MBs in size, the entire file needs be downloaded before playback can begin in IE/Edge.

This results in a weaker user experince in IE/Edge. The MS Edge team talks about interoperability a lot lately (Awesome!) this is one area where users would see a big benefit from better interoperability.

Thanks

    • Hi, thanks for your response. Is there a web based version of Windows Feedback? (I Googled for it, but just got articles with the same steps you have provided.)

      I’m a web developer, and don’t personally have a copy of Windows I can access. We’ve noticed (and received customer feedback) that videos can take a lot longer to play in Internet Explorer and MS Edge than other browsers. We did some testing, and found this was the cause, which is why I submitted it as an issue here.

      I’d love to submit it through the proper channel, is that possible without having a Windows OS available?
