Visit https://repositorio.ufsc.br/handle/123456789/134062 2. Play the 2 video's on that page (both using the video tag) 3. Bottom one plays, top one doesn't What is the expected behavior? Both are expected to play What went wrong? The video file of 170MB (https://repositorio.ufsc.br/bitstream/handle/123456789/134062/cap1.mp4?sequence=1&isAllowed=y) doesn't play, even though it has the exact same properties as the 10MB (https://repositorio.ufsc.br/bitstream/handle/123456789/134062/cap1_min.mp4?sequence=2&isAllowed=y) file. Did this work before? N/A Is it a problem with Flash or HTML5? HTML5 Does this work in other browsers? Yes Chrome version: 51.0.2704.7 Channel: dev OS Version: Ubuntu 14.04 Flash Version: Shockwave Flash 21.0 r0 Issue has been reported via the helpforum: https://productforums.google.com/forum/#!topic/chrome/MRfslGQJ7h8

1. The server doesn't seem to support range requests. 2. The video files seems to be muxed in a way that requires the browser to download the entire file before it can play it. I suspect chrome just times out before the entire file is downloaded. (The bottom video seems to also exhibit this problem if your connection is slow.)

Looking at the code, Chrome is trying to play a video enclosed in HTML5 <video> tag. I feel this is a feature parity issue between other browsers and Chrome. Compared to Chrome, Firefox and Edge 1. were able to load the video 2. Allowed user to randomly watch a video from any point 3. Kept video in cache (In case user reloads the page or Chrome discards a tab)

What if the video is 1Gb? 10Tb? How much should we download and keep in the cache? Video playback without support for range requests is just never going to be a great user experience, and it's hard to guarantee that it will even work. While we would of course prefer every video on the web to play in chrome, it's not clear to me that this is worth fixing, when fixing the web server leads to a much better experience for the user. (On all browsers.) Unless of course the cause of this problem is not what I think it is.

Hi hubbe, I totally agree with your comment and can live with chrome not being able yo play a 1TB file. However I logged this issue to get a solution to something that is unacceptable: having to go through the helpforum in order to get this information. Having a play video player which is not responding, not giving an error ... is very strange. User experience: 'chrome is broken', while you actually would expect 'something is wrong with the website'
