I get several emails everyday to my Gmail account, from my security camera system. Such mail contains links to video clips (aprox 20 sec each) from cameras in MP4 format.
Strange is that on Mageia based PC after clicking on such link the clip is open and playback in new separate browser card. And it is correct situation for me. But on Ubuntu based PC, Chrome always download video clip to HDD instead playback one.
I dont know is it Linux distribution related problem but both installations use Chrome ver 38.
How can I change/setup to have MP4 files always be playback instead downloaded ?
Are you using Google Chrome or Chromium on Ubuntu, as a matter of interest? Either way the issue may be that MP4 support has not been enabled.
To enable it you need to install the support for mp4 codec:
sudo apt-get install chromium-codecs-ffmpeg
The reason for this is that some codecs are not fully open source, because they may be subject to patents for example, and hence they can't be included in a fully open source release.
See some discussion and references:
https://github.com/videojs/video.js/issues/675
https://launchpad.net/ubuntu/precise/+package/chromium-codecs-ffmpeg-extra
I resolved the problem by emailing not direct link to particular video clip but by email link to WEB page containing HTMLv5 code with "video" statement. It is more flexible because it works in any environment and in any browser compatible with HTMLv5.

I'm developing a Video on Demand feature for a Django project of mine. It's going to be powered by Azure Media Services.
Currently, I'm trying to run an uploaded video via the following code:
<video id="azuremediaplayer" class="azuremediaplayer amp-default-skin amp-big-play-centered" controls autoplay width="640" height="400" poster="" data-setup='{"techOrder": ["azureHtml5JS", "flashSS", "silverlightSS", "html5"], "nativeControlsForTouch": false}'>
<source src="{{ video.streaming_url }}" type="video/mp4" />
<p class="amp-no-js">
To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video
</p>
</video>
where {{ video.streaming_url }} contains a streaming url of the sort http://example.streaming.mediaservices.windows.net/66193aae-b739-4cb5-b4b9-f4a4a151c791/myproject.ism/manifest.
My problem is that I get the error no compatible source found for the current browser environment (0x10600003). In fact, I get that error when I go to http://ampdemo.azureedge.net/azuremediaplayer.html as well (i.e. an official azure media player demo).
It seems the 0x10600003 error code implies Autoselect failed to find a player. Note that Youtube videos work perfectly in my environment. My OS is Ubuntu 14.04, and the browser is Mozilla Firefoz 41.0.1. A previous unaccepted answer guided the op to install and enable Silverlight. I can't expect all my users to do that. How do I get playback to work?
Azure Media Player is built on 4 different players, a DASH player, a Flash player, the Silverlight player, and the native implemented player for the browser you're watching the video on. These different "Player Techs" playback different protocols supported my Azure Media Services- DASH, Smooth, and HLS.
AMP intelligently decides which player/playback protocol to use for a specific/device or browser by looking at what technologies/features the browser supports. First, it'll check if the browser supports Media Source Extensions. MSE allows the browser to playback adaptive bitrate streams without the use of plugins like Flash and Silverlight, it's supported in most modern browsers, but not always in older versions of those browsers. If MSE is supported,AMP will playback your content using the MPEG-Dash protocol and you're good to go. If MSE isn't supported, AMP will check and see if Flash is installed and then if Silverlight is installed. If either of these are true it will play back using the installed plugin and the Smooth Streaming protocol. If neither of them are installed, it will try to play back via the native html5 video tag implementation of the browser. This is completely dependent on the browser, and most do not support ABR streams natively (except, for example, Safari via HLS)
Your short answer, given this background information, is that because you are using an older version of FF that does NOT support MSE, you need to install either Flash or Silverlight to play back your adaptive bitrate streams.
a few mitigations for you/customers:
1) install Flash/Silverlight
2) download an up-to-date version of FF, we recommend this for sure because MSE is supported in v42 but in v47+ Google Widevine protected content is supported, which means you can playback DRM encrypted content without Silverlight
see Azure Media Player's Compatibility Matrix for more info on what's supported on which browsers.
If you have any more questions, you can email me at ampinfo#microsoft.com, hope this helps!
I just knocked off the content policy and created a new one and it started working again.
In short, I have to play RTSP on a Google TV device (Sony nsz-gs7). How can I do it?
Things I tried:
Use NDK to compile ffmpeg, then ffmpeg converts rtsp to udp etc. - Fails because NDK is not supported in Google TV (see: https://developers.google.com/tv/faq#ndk). This method uses ffmpeg as library.
Put ffmpeg executable (compiled with NDK) in an application, then call the app from command line. (see: http://gimite.net/en/index.php?Run%20native%20executable%20in%20Android%20App - first method). I can deploy executable and set its permissions, but cannot execute it; i get "not found" error (its path is correct). If only I could run an executable file in Google TV, the problem would be solved, I think.
Tried to display in VideoView, like Google TV VideoView playing YouTube rtsp videos, it didn't work either.
These approaches all work on Android phones, but I couldn't make them work on Google TV.
Any tips for displaying RTSP or running executable files? Or do I have to wait for NDK support?
Update: If there is an application which can play RTSP streams, we can also use it as a temporary fix.
The current version of Google TV is based on FFMpeg internally and is supposed to play RTSP content of course, if you try that example, you'll want to refresh the url for the RTSP content as YouTube doesn't keep them live long. Since RTSP is a transport format, not a codec, you might want to say what your encoding is.
That said, I've never made RTSP work myself - so I'm not speaking from experience, but I do trust my colleague Shawn who wrote the answer to the link above.
One of the features we announced at Google I/O 2012 was the ability to write your own transport stream and codec's in Java. That software is currently on the LG and will be on most of the others in the next few months.
If your need is urgent write me at Google or on Google+.
I have searched for various articles about playing mp3 files in firefox but no luck.
I want something similar to this website for playing my audio files:
http://www.waatea603am.co.nz/podcasts
Can anyone tell me how is the audio files being played in the website. I want to do something similar. I cant figure out how it is being done.
Thanks
Here's the JavaScript that makes the links play sound:
http://www.waatea603am.co.nz/Resources/JavaScript/podcast-audio.js
It's basically using the HTML5 Audio element:
<script type="text/javascript">
var snd = new Audio("file.mp3"); // buffers automatically when created
snd.play();
</script>
http://www.w3.org/wiki/HTML/Elements/audio
This isn't really a "programming" question, as much as a "Firefox configuration" question.
Personally:
I don't really have any preferences of "media player" for Linux
I simply use Windows media player for Windows
Windows Media player comes built in with all recent versions of Windows
Windows media is the default file association for .mp3 on all recent versions of Windows
Consequently, Firefox automatically uses Windows Media player to play .mp3's

Unfortunately, most commercial Internet radio stations seem to use Flash to broadcast audio streams. Sigh...
Play Apple's .caf audio file on a webserver? I have .caf audio files (Apple's open audio format) stored on my webserver and want to play them from a web browser on any O/S.
I understand, this doesn't seem like the solution you're looking for, but...
Several weeks ago we faced the same problem. We have several clients which are posting audio files to the web site from theirs iPhones, and we need to play audios on the web site.
But we didn't find any suitable flash player with .caf format support.
So we decided to convert .caf to .mp3 on the server through the ffmpeg.exe utility.
Happily, there a lot of flash players with .mp3 support.
Now I have not tried this... but...
This website:
http://modmyi.com/forums/skinning-themes-discussion/1769-how-do-i-create-caf-file.html
Seems to suggest that .CAF and .AIF may work interchangeably (It suggests that to convert to .CAF you convert to .AIF` and then rename the file).
Have you tried renaming it to .AIF and trying to play in a flash/java browser player? Alternatively just send it as a stream to the web-browser and let the client OS work out what to do with it (Like quicktime running inside the browser).
Let me know how it goes.
What is the recommended (cross-browser) video format to use on websites so that users' browsers (or most of them) wouldn't require to download a plugin to view it?
There is no single video that will play in every browser. If you want it to work across the most browsers, you're going to have to encode your video more than once. Dive into HTML5 video has the gory details.
You nest your video references so that browsers try these in order, falling back if it's not supported:
Ogg Theora
MP4 H.264
A Flash container displaying #2
Number 1 gets you Firefox 3.5 and Chrome. Number 2 gets you Safari and the mobile phone WebKit browsers. Number 3 gets you IE, Firefox ≤3, and Opera.
There is no such format available yet. The best way to go is:
Flash (most of the users have flash plugin installed already, 99% according to http://www.adobe.com/products/player_census/flashplayer/)
OGG (This will be available in HTML5 as standard)
Yes HTML5 will solve some of the problems of not needing a plugin, but different browser vendors have chosen different codecs and file formats. It's complicated, but Dive Into HTML 5 has a great article.
None! but you can do it with HTML 5 which is not implimented by all browsers ...
if you really need a video on your page i would recommend flash or silverlight
In a couple of months HTML 5 will be supported by almost all browsers on this planet. If you are planning to run your services in 2010 just use OGG open standard container format. It is unrestricted by software patents and is designed to provide for efficient streaming and manipulation of high quality digital multimedia. It is already supported by Firefox 3.5 and soon all browsers will support it.
Please look at documentation and wiki on http://www.xiph.org/ogg/
