Angular Notes

I have been doing angular for around six months by now. It's pretty cool that I don't feel bored to write javascript and htmls anymore. I guess you can take a look at it too.

Where to go first ?

1. Their website
• https://angularjs.org/
2. I guess you can start with this video first. It's just a twenty minutes amazing youtube video on angularJS for beginners
• https://www.youtube.com/watch?v=tnXO-i7944M
3. Their official phone cat app. I didn't liked it that first. But I heard they updated it. I am going to read it right after finishing my notes
• https://docs.angularjs.org/tutorial
4. You can also subscribe to their youtube channel.
• https://www.youtube.com/user/angularjs
5. Google is your friend. There are so many useful and interesting blogs,books and tutorials on angularJS. Please explore yourself
• www.google.com

In this github repo. I wrote a few commits to introduce myself with angularJS. I will be describe them from commit to commit tomorrow.

How to publish a live stream (MPEG-TS based encoder)

The procedure I followed is mentioned in details here
http://www.wowza.com/forums/content.php?37
I am using , Linux Mint-13 and wowza media server-3.


The basic steps for setting up an application for live streaming and configuring Application.xml :

     1. Create application folder [install-dir]/applications/live. [ I have this application already available ]  
     2. Create configuration folder [install-dir]/conf/live [ I have this application already available ]  
     3. Copy/Overwrite Pre-configured version of Application.xml to [install-dir]/conf/live  
     4. From Application.xml, changes the followings if they are not already configured  
         1. Set the Streams/StreamType property to:  
                <StreamType>live</StreamType>  
         2. Set the HTTPStreamers property to:  
 <HTTPStreamers>cupertinostreaming,smoothstreaming,sanjosestreaming</HTTPStreamers>  
         3. Set the Streams/LiveStreamPacketizers property to:  
 <LiveStreamPacketizers>cupertinostreamingpacketizer,smoothstreamingpacketizer,sanjosestreamingpacketizer</LiveStreamPacketizers>  
         4. Set the RTP/Authentication/PlayMethod property to:  
 <PlayMethod>none</PlayMethod>  

Publishing the stream :

    1. Create .stream file:  
        a. Use a text editor to create the file [install-dir]/content/mpegts.stream and set the contents of this file to udp://[myip]:10000. If you're receiving a multicast stream, change [myip] part of the URL to the multicast address of the stream.  

             

 b. Using a text editor, edit the [install-dir]/conf/admin.password file and add a username and password that will be used to start and stop the publishing of the MPEG-TS stream (below is an example of the file with the username myuser and password mypassword):   

     

   3. Start/Restart Wowza Media Server.     
    4. Use Stream Manager to start the MPEG-TS stream:          
             a. Enter the following URL in a web browser:   
                    URL: http://[wowza-ip-address]:8086/streammanager    
             b. In the Security dialog box, enter your admin username and password from above.     

           

        c. In the Stream Manager webpage, click the [start-receiving-stream] link just below the live application folder.         
        d. In the Start Receiving Stream dialog box, select the following MediaCaster Type option: rtp  
        e.In the Stream Name field, enter mpegts.stream and press ok.   

Publish stream using ffmpeg : 

 

  $ ffmpeg -re -i file.ts -acodec copy -vcodec copy -f mpegts udp://192.168.43.129:10000?pkt_size=1316 I played the stream using mplayer  

I played the stream using mplayer

 $ mplayer -msglevel all=6 rtmp://192.168.43.129:1935/live/mpegts.stream
