Is it possible to live stream cable movies on my website with your plugin?

Live Streaming allows using an external encoder or screen sharing.

Screen sharing is possible with external tools as explained on:

Thanks for your reply. since I am new to this field, would you please let me know if I get the external encoder, do I still need a video streaming server? because I am not sure with Live Streaming Plugin how can I connect to the External Encoder.

Thanks again

Yes, a rtmp streaming server is always required to distribute the stream to the viewers.

This software has special requirements (for the video streaming and live interaction part, regular shared web hosting is not enough):

Options for the required rtmp hosting:
https://www.videowhisper.com/?p=RTMP+Hosting

You can use our rtmp hosting plans for everything (web+rtmp) or in combination with your other web hosting (install application on your site and configure it to use rtmp address from a plan you have with us).
All our plans are on special streaming servers with 1000Mbps connection (10x higher than regular) to handle such use.

On commercial production sites, achieve complex functionality and performance with Wowza hosting:

All Wowza plans come with features like optimised archiving, recording, transcoding for iOS support and rtmp stats.
If you plan to use video stream recordings or archives we recommend using same physical server both for web and rtmp so your web scripts can access the video files on rtmp server (for file management, ffmpeg conversion).
There is also a $50/month developer plan for testing and development phase.

You can also use hosting based on the open source Red5 server for high volume of bandwidth at lower rate:

Red5 plans are not recommended for archiving or recording.

If you want to host yourself you’ll need a VPS or Dedicated Server to install Red5. Our staff can provide Red5 installation:

If you have a big site or project, you’ll probably need a managed dedicated red5/wowza server focused on bandwidth and connectivity:

Thanks for your help, really appreciate it.
