@burnout426 I can load with Vivaldi

I see. I tried with the 32-bit stable version of Vivaldi and I was indeed able to play the video after a second reload of the page. Still can't play with the latest snapshot. Wonder if it's a difference in Chromium versioned used. And, maybe this is a recent regression in Chromium. Thanks for checking.


@nneo16 said in Videos in website kinhdoanh.vpnexpress.net won't play:

With http://m1.chiasenhac.vn/hd/video/o-video/romance~nacho-justin-quiles~tsvdzwwtqm199f.html, after the ad when the site tries to load the video, there's a MediaError that shows up in the console for the video with code 4, which says the source isn't supported (demuxing failed).

However, if I download the mp4 file and play it locally in Opera, it works just fine.

Masking as another browser doesn't fix the issue and I'm not sure if it's an error in the javascript code or not. However, since the server sends the mp4 with a mime-type of application/octet-stream (instead of video/mp4 for example), I'm *guessing* Opera doesn't like that for some reason, while Chrome is fine with it.

Testing with Vivaldi and Chromium, the video doesn't load either. I guess Chrome (and Firefox) have extra code to sniff the actual contents of the mp4 file to find out if the file can be played and play it, while basic Chromium, and others based on it, don't and just look at the mime type and say, "This isn't a video".

If anyone can find a contact for the site, that'd help. Maybe they can fix the type.

The last one allows you to set an user agent for a specific site.

For that one at least, Opera has no problem playing the video directly. What seems to be happening is that after the intro on the page loads and it tries to switch to that video, nothing happens. If you right-click on the video area and inspect, you'll see that the video container doesn't have a link to the mp4 like it does in Chrome.

So, for that page, to work around it, install the User Agent Switcher extension and set the user agent to Chrome for Windows for example and the video will load in Opera.

Many websites have problem playing media in Opera, while other browsers like Chrome, Firefox open flawlessly.

I tested on many computers with different OS and lastest stable build.

Most normal users don't want to report bugs, they just pick the one that open their day to day websites without problem, now you got our report and just say "normal here" ?

What happens when you try to play the videos? Try checking opera://media-internals/ while trying to play the videos to see if it gives you a hint of what may be happening.
