Live

A typical live source is UDP multicast, which is the only live protocol packager supports directly right now.

UDP file options

UDP file is of the form udp://ip:port[?options]. Here is the list of supported options:

reuse=0|1:Allow or disallow reusing UDP sockets.
interface=<addr>, source=<addr>:
 Multicast group interface address. Only the packets sent to this address is received.
timeout=<microseconds>:
 UDP timeout in microseconds.

Pipe through FFmpeg

For other unsupported protocols, you can use FFmpeg to pipe the input. See ffmpeg piping for details.

Examples

The command is similar to the on-demand, see DASH and HLS.

Here are some examples.

  • DASH:

    $ packager \
  'in=udp://225.1.1.8:8001?interface=172.29.46.122,stream=audio,init_segment=audio_init.mp4,segment_template=audio_$Number$.m4s' \
  'in=udp://225.1.1.8:8001?interface=172.29.46.122,stream=video,init_segment=h264_360p_init.mp4,segment_template=h264_360p_$Number$.m4s' \
  'in=udp://225.1.1.8:8002?interface=172.29.46.122,stream=video,init_segment=h264_480p_init.mp4,segment_template=h264_480p_$Number$.m4s' \
  'in=udp://225.1.1.8:8003?interface=172.29.46.122,stream=video,init_segment=h264_720p_init.mp4,segment_template=h264_720p_$Number$.m4s' \
  'in=udp://225.1.1.8:8004?interface=172.29.46.122,stream=video,init_segment=h264_1080p_init.mp4,segment_template=h264_1080p_$Number$.m4s' \
  --mpd_output h264.mpd

  • HLS:

    $ packager \
  'in=udp://225.1.1.8:8001?interface=172.29.46.122,stream=audio,init_segment=audio_init.mp4,segment_template=audio_$Number$.m4s,playlist_name=audio.m3u8,hls_group_id=audio,hls_name=ENGLISH' \
  'in=udp://225.1.1.8:8001?interface=172.29.46.122,stream=video,init_segment=h264_360p_init.mp4,segment_template=h264_360p_$Number$.m4s,playlist_name=h264_360p.m3u8' \
  'in=udp://225.1.1.8:8002?interface=172.29.46.122,stream=video,init_segment=h264_480p_init.mp4,segment_template=h264_480p_$Number$.m4s,playlist_name=h264_480p.m3u8' \
  'in=udp://225.1.1.8:8003?interface=172.29.46.122,stream=video,init_segment=h264_720p_init.mp4,segment_template=h264_720p_$Number$.m4s,playlist_name=h264_720p.m3u8' \
  'in=udp://225.1.1.8:8004?interface=172.29.46.122,stream=video,init_segment=h264_1080p_init.mp4,segment_template=h264_1080p_$Number$.m4s,playlist_name=h264_1080p.m3u8' \
  --hls_master_playlist_output h264_master.m3u8

Note

Packager does not support removing old segments internally. The user is resposible for setting up a cron job to do so.
