Broadcasting 24/7

For setting up a 24/7 livestream you may want to change some default publishing parameters. Use the mp4split to create the server manifest file before the encoding is started.

You can also interact with a publishing point using our Publishing Point API.

Create the publishing point

You can use the following command to create the server manifest:

#!/bin/bash

mp4split -o /var/www/live/channel1/channel1.isml \
  --archive_segment_length=60 \
  --dvr_window_length=30 \
  --archiving=0 \
  --restart_on_encoder_reconnect

This wil create a directory ‘channel1’ in the /var/www directory, which is Apache’s DocumentRoot in a standard configuration. Within the directory, a server manifest (channel1.isml) is created, configured according to the options listed in the command.

With the archiving option set to 0, the publishing point only stores the last archive_segment_length of seconds to disk. In the example above, this is 60 seconds, which ensures that the storage requirements for running a 24/7 stream are minimal.

After you have created the publishing point, you can start the encoder, with the URL of the publishing point as the address to which it will its output. For example:

http://live.example.com/live/channel1/channel1.isml

Please note that you should change ‘live.example.com’ to your own URL.
