Steps to follow before running the app (the below steps are done on a Windows machine using WAMP):

1. Download ffmpeg, extract it and add it to PATH
2. Install WAMP Server, create a folder called 'live' in the 'www' directory
3. To prevent CORS issue with WAMP you must add the line - Header set Access-Control-Allow-Origin "*" in the httpd -vhosts.conf file and make sure the headers-module is installed.
4. Now create a batch file with the following lines and save it

   cd c:\wamp64\www\live
   set VIDSOURCE="rtsp://url" &:: put your url here  
   set AUDIO_OPTS=-c:a aac -b:a 160000 -ac 2  
   set VIDEO_OPTS=-s 854x480 -c:v libx264 -b:v 800000  
   set OUTPUT_HLS=-hls_time 10 -hls_list_size 10 -start_number 1  
   ffmpeg -i %VIDSOURCE% -y %AUDIO_OPTS% %VIDEO_OPTS% %OUTPUT_HLS% mystream.m3u8  
   PAUSE```

5. Run the batch file. If successfully done you should see some output in the command prompt and streaming files will begin getting created in the C:\wamp64\www\live directory.
6. Make sure WAMP is running along with all its services.
7. Now you can run the app.
