Can you play this MP4 ?

There is yet another debate shaping about MP4 in another thread. It just seems to keep coming back. 

I boldly suggest that a properly formatted MP4 displayed on a page in HTML5 video tags is enough.

I tried putting one directly in this post but Moodle was not having it. So please try and view it here:

Does it work? If not, post back here what your browser and device are.

Viwed it and is works fine on Firefox 37.0.2.

But it looks like the frame rate is low...

Thanks for checking. . The video quality is just because of my cheap camera and low quality settings.

All browsers are running on Windows 7.0 (32-bit), and here's the outcome

FireFox 37.0.2 - OK

Google Chrome 42.0.2311.135 - OK

Opera 20.0.1387.91 - OK

Safari 5.1.7 - OK

Maxthon Cloud Browser 4.4.5.1000 - OK

Internet Explorer 9 - Didn't played, so assuming its HTML5 player and IE doesn't natively supports HTML5, only Flash.

Video play remained consistent across all, the lag I believe is due to the camera capture else voice is synched properly meaning no issues with the video itself.

Thanks for testing everyone. It seems so far only IE is giving issues. 

My own IE 11 on Windows 8 plays it back fine. It looked to be a player loading problem rather than a format problem on Dereks screenshot. In hindsight I should have just embedded it with HTML5 video tags and no fancy player. So I changed it now to that. And I remade the video, because everyone complained about my shoes and chair in the last video.

The video codec that FFMPEG produced for that video was: AVC (H.264) profile baseline 3.1

http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

The audio was: AAC

I also tested it with: 

iOS 8 : Mobile Safari (Version 8) : OK

Windows 8: Chrome (Version 42): OK

Mac Maverick (OSX 10.2.2): Chrome (version 42): OK

( I use http://www.whatsmybrowser.org/ to get all the versions)

We really need some people on windows phones and android devices to see if they can break it.

Second round. The video quality is much better. Still not like YouTube, but that is the recording, I believe.

- Chromium 37.0, Debian GNU/Linux 7.8
No problem at all.

- FireFox (Iceweasel) 31.6, Debian GNU/Linux 7.8
Video plays well, quality similar to Chromium. But the picture lags the audio.

- Android 4.1.2, built-in browser and Chromium
Plays well, still there is a noticeable lag between audio and the picture.

Hi Justin

Thanks, as always, for your efforts in the video world of Moodle.

I tested the link on some Android devices:

A Nexus 6, a OnePlus One, a Nexus 7 and a Nexus 4

All worked fine with the standard browser, Opera, and Boat (a great browser for solving compatibility issues!)

The Nexus 6 and the Nexus 4 were running 5.1, the Nexus 7 - 5.1.1, and the OnePlus One Cyanogen Mod (5.0.2)

Just for fun I tried it on a Series 1 Galaxy Tab running Androis Froyo - the stock browser didn't work, but the video played fine on Opera!

It seems like you've got Android pretty well covered!

All the best


Andy

On my Windows 7 Dell laptop it plays in Google Chrome 42.0.2311.135.

No problem in Firefox 35.0.1 either.

But Internet Explorer 9.0.8112.16421 shows just a "black box" with a little red "X" in it. No video...
