I want to develop an application to play live stream on Windows mobile devices. Please give me an example of this.
That is a fairly broad question. There is a MediaElement control you can use to play video. Maybe the open source PlayerFramework is more helpful. It provides a way to play lots of content, including progressive downloads, streaming, live streaming, protected content, advertisements, etceteras. And you can style the player as you see fit.
Have a look at http://playerframework.codeplex.com for the downloads, sources and documentation.
An easy start can be found here: Getting Started Guide.

How to do:
Pre loading video on play
Change resolution
Change language
In multiple platforms I see these techniques used but I can't understand which api they use to do these things does anyone have an idea?
(Sorry for the ignorance I'm Junior developer)
If you are using HTML5 on a browser then there are a set of events which the HTML5 video playback generates at different stages and which you can register to monitor and then take whatever action you want - for example change language etc.
There is a really nice illustration of the various events and their values when a vide plays (at the time of writing) here:
https://www.w3.org/2010/05/video/mediaevents.html
It's worth noting that the type of features you are describing are usually built into a HTMl5 video player if it is on a website or a native player if it is on Mobile.
For example on a browser the open source DASH if player, https://reference.dashif.org/dash.js/latest/samples/dash-if-reference-player/index.html, will change resolutions for ABR streams and provide the user controls to change it manually and to set the langage.
On Android the open source ExoPlayer, https://github.com/google/ExoPlayer, provides similar functionality, and on iOS the built in media library https://developer.apple.com/documentation/avfoundation?language=objc, provides similar functionality.
To understand ABR streams and how and why they change resolutions this answer may help: (https://stackoverflow.com/a/42365034/334402)
After several years working with commercial and custom Flash video players, such as Flowplayer and jwplayer, I decided to open my work to html5. I like the idea of having a Flash impersonation of html5, so I tried medialements.js, video.js and jplayer. None of them are production ready and they all fail to meet my goal, which is playing a video on a webpage, desktop and mobile, live and vod.
Does anyone has a suggestion for a working web video player, apart from the commercial ones?
TIA

I can get to what you are saying. Videojs is a leader in HTML5 video and considered state of the art by many though I think it falls short on some aspects especially for iOS/Android and Live streaming. Here is a list that compares some common actors of the market.
After much time playing with the different players available I decided to build my own HTML5 video jQuery based player. I learned so much while doing so and if you are planning on re-using it for your projects it will be much faster to tweak your own player rather than trying to build something up on a player someone else built. Now doing so requires you like JavaScript and are happy to deal with the cross browser testing. This article can give you a place to start. Digging in further would require you take on board the W3C spec.
Live streaming in HTML5 video is limited today: HLS for iOS and Android > 4.1 and coming in fast MPEG DASH (it has a JS lib for live and on demand here). If you want to cover a large audience for live video streaming you still need to consider flash.
I would like to clarify certain things with what I found and raise certain questions with things that I dont know,
Capturing cam/mic through browser could be done through getusermedia();
Is there anything for i devices? because getusermedia() doesn't seem to work in i devices
How could I trap actual audio from web browser application (eg. if I play an audio file and forward it 2mins, I would like to capture the actual audio stream from the html5 player so that I hold the actual audio data)
You need to use Flash, if you are not going to support mobile devices. One best solution is to use wami-recorder.
From their website:
The Problem
As of this writing, most browsers still do not support WebRTC's getUserMedia(), which promises to give web developers microphone access via Javascript. This project achieves the next best thing for browsers that support Flash. Using the WAMI recorder, you can collect audio on your server without installing any proprietary media server software.
The Solution
The WAMI recorder uses a light-weight Flash app to ship audio from client to server via a standard HTTP POST. Apart from the security settings to allow microphone access, the entire interface can be constructed in HTML and Javascript.
Hope this helps.
I have a jQuery Mobile website I created for a friend/client of mine. It only has 6 pages or so (2 of them are dialog windows). The site has HTML5 video with fallback for flash support via the videojs library. All videos are encoded properly in mp4, ogv (theora), and webm and so far play on every device I have used.
My problem lies bandwidth, the purpose of the program really needs to be an application because these are informational videos that may need to be viewed at any time, even with no web access (web access is required for first login to verify credentials).
I was left with 3 solutions, try writing native apps for all the platforms myself in their native languages, use Sencha Touch (which I am comfortable enough with extJS to do), or taking my existing jquery mobile app that is 100% functional including log-in and some backend package management to assign users a package of videos (there are multiple packages each with between 8-20 videos), and follow the jQuery Mobile tutorial for getting your app ready for PhoneGap, I believe its only enabling two settings, and both are to enable "cross-domain" requests, since my current web app would be running as localhost, it would see the scripts as external pages.
My main question/problem is for one, I have never used PhoneGap; aside from their Hello World android tutorial, and I know there are other all-in-one frameworks out there now: PhoneGap, Titanium, Corona, Adobe Flex (which I am installing while writing this tutorial, to see what it has to offer. If it has features like encoding videos automatically for the target device (video resolution changing), or even has local video playback features at all that may work.
Does anyone know which of the current frameworks have the ability to install a set of videos to the sdcard, (totaling around 6mb per install), and play them natively (by that i mean, in the devices native player, not inline inside of a webview). Which on android phones anyways, my current videojs based player plays the files natively in everything I have tried it on.
I just need a push in the right direction, if there is a PhoneGap plugin that I don't know about that allows videos to be played from the sd card, that would be terrific. Although I am not very happy with the speed of the android and blackberry webview controls. So something that uses 100% native controls would be great. I hope you guys can come up with some ideas, you can see the current app in action at m.yourvideobenefits.com email:abc#tool.com password: demo
You should view it from your phone if you want to see it properly, but if you do not have a smart phone; keep in mind that when viewing this page certain desktop browsers, the videos become their actual size after they are through loading. This is because i have autoload="true" in the video tag (which is ignored on most phones, but believe it or not, setting autoload="true" is what actually allowed the videos to not play inline on certain devices. A bug on the device, I am sure...but without this tag the videos played inline on iPhone 4 with the latest iOS version.
You could do it very easily with phonegap; you already have your web page, so it would be much less work, probably.
You could get the videos from inside your apps bundle in ios, and then it wouldn't be hard to select the one with the best resolution for the device being used. You could also download the videos at the perfect format and resolution the first time your app plays from your server using the file api. That convined with the storage api is nice for actualizations.
There's a plugin I use for android, because video tag is sometimes bugged or doesn't work at all in older versions, https://github.com/phonegap/phonegap-plugins/tree/master/Android/VideoPlayer.
It only plays from web or sdcard, but that's rarely too bad.
I can't help you with black berry, but I'm pretty sure there must be a way of doing it. And, anyway, appcelerator doesn't support it yet, so you would probably had to do it natively. Even if there isn't a plugin for black berry, you'd probably have to chose between native developement and html5 player inside phonegap. I won't give you my opinion about it here, for I'm not the one to give it and Stack Overflow says I shouln'd give it anyway.
I was wondering how to embed a video on a webpage to have it compatible with mobile devices. I am kinda new to the whole mobileweb. So I set up some testing pages and tried them out with some devices of my friends. Flash is obviously not the way to go. Embed tag neither. html5 video tag neither. I also tried to nest them for fallback compatibility but just didn't get it right.
So I had a look at youtube. They are using rtsp streams and they just let the device handle the rtsp:// links. This seemed to be working everywhere, and I think they do it for a reason. So I had a look at rtsp protocol the possibilities to serve such a stream.
Turned out its really simple and doesn't really differ much from the http protocol. There is e.g. ffserver out there for that.
But every free/os implementation seems to be testing/buggy ...
So I ask you guys. I cant be the first stumbling across this problem.
Isn't there a nice tested way to embed videos with nice compatibility for mobile devices? preferably served from a http source!
looks like html5 is the way to go but important are the correct encoding settings.
h264, baseline 1.3 seems to work fine with iphone4 and android 2.1 ... rest untested.
I've been collection information about mobile compatible video players, you can find it here: http://blog.jsethi.com/media/html5-video-players/
The solution would be to use Kaltura open source platform. If you have have the knowledge to set it up it's the winning solution.
Here is my kaltura running HTML5 with flash fallback. http://cdpn.io/DeKuo
