Demuxing an MPTS Stream

MPTS (Multi Program Transport Streams) streams can be demuxed into single SPTS (Single Program Transport Streams) streams. MPTS demuxing is available for Pull, Push, UDP, and File input streams. From the various programs in the MPTS stream, you can select specific programs, which will be turned into induvial SPTS input streams. 

To demux an MPTS stream:

1. Create a Pull/Push/UDP/File input stream using an MPTS stream.

2. In the Inputs page, click the newly created input stream that you want to demux.

3. Click the action

   Open

   

   button on the right end of the selected row and then Edit.

6. In the Max Bitrate field, specify the maximum bitrate of the stream. This is used for internal memory allocation and will not affect the transmitted bitrate. Recommended: double the bitrate of the highest bitrate stream.

7. Configure additional parameters as necessary.

8. Click OK.
   The channel is assigned an input:
