Ad Insertion
============
Shaka Packager does not do Ad Insertion directly, but it can precondition
content for `Dynamic Ad Insertion <http://bit.ly/2KK10DD>`_ with Google Ad
Manager.
Both DASH and HLS are supported.
Synopsis
--------
::
$ packager <stream_descriptor> ... \
--ad_cues <start_time[;start_time]...> \
[Other options, e.g. DRM options, DASH options, HLS options]
Examples
--------
The examples below use the H264 streams created in :doc:`encoding`.
Three midroll cue markers are inserted at 10 minutes, 30 minutes and 50 minutes
respectively.
* DASH with live profile::
$ packager \
'in=h264_baseline_360p_600.mp4,stream=audio,init_segment=audio/init.mp4,segment_template=audio/$Number$.m4s' \
'in=input_text.vtt,stream=text,init_segment=text/init.mp4,segment_template=text/$Number$.m4s' \
'in=h264_baseline_360p_600.mp4,stream=video,init_segment=h264_360p/init.mp4,segment_template=h264_360p/$Number$.m4s' \
'in=h264_main_480p_1000.mp4,stream=video,init_segment=h264_480p/init.mp4,segment_template=h264_480p/$Number$.m4s' \
'in=h264_main_720p_3000.mp4,stream=video,init_segment=h264_720p/init.mp4,segment_template=h264_720p/$Number$.m4s' \
'in=h264_high_1080p_6000.mp4,stream=video,init_segment=h264_1080p/init.mp4,segment_template=h264_1080p/$Number$.m4s' \
--ad_cues 600;1800;3000 \
--generate_static_live_mpd --mpd_output h264.mpd
* DASH with on-demand profile::
$ packager \
in=h264_baseline_360p_600.mp4,stream=audio,output=audio.mp4 \
in=input_text.vtt,stream=text,output=output_text.mp4 \
in=h264_baseline_360p_600.mp4,stream=video,output=h264_360p.mp4 \
in=h264_main_480p_1000.mp4,stream=video,output=h264_480p.mp4 \
in=h264_main_720p_3000.mp4,stream=video,output=h264_720p.mp4 \
in=h264_high_1080p_6000.mp4,stream=video,output=h264_1080p.mp4 \
--ad_cues 600;1800;3000 \
--mpd_output h264.mpd
This generates six single-segment media files, one per stream, spanning multiple
periods. There may be problems handling this type of DASH contents in some
players, although it is recommended by `DASH IF IOP <http://bit.ly/2B0HL9q>`_.
Use the below option if your player does not like it.
* DASH with on-demand profile but one file per Period::
$ packager \
'in=h264_baseline_360p_600.mp4,stream=audio,output=audio_$Number$.mp4' \
'in=input_text.vtt,stream=text,output=output_text_$Number$.mp4' \
'in=h264_baseline_360p_600.mp4,stream=video,output=h264_360p_$Number$.mp4' \
'in=h264_main_480p_1000.mp4,stream=video,output=h264_480p_$Number$.mp4' \
'in=h264_main_720p_3000.mp4,stream=video,output=h264_720p_$Number$.mp4' \
'in=h264_high_1080p_6000.mp4,stream=video,output=h264_1080p_$Number$.mp4' \
--ad_cues 600;1800;3000 \
--mpd_output h264.mpd
* HLS using transport streams::
$ packager \
'in=h264_baseline_360p_600.mp4,stream=audio,segment_template=audio_$Number$.aac' \
'in=input_text.vtt,stream=text,segment_template=output_text_$Number$.vtt' \
'in=h264_baseline_360p_600.mp4,stream=video,segment_template=h264_360p_$Number$.ts' \
'in=h264_main_480p_1000.mp4,stream=video,segment_template=h264_480p_$Number$.ts' \
'in=h264_main_720p_3000.mp4,stream=video,segment_template=h264_720p_$Number$.ts' \
'in=h264_high_1080p_6000.mp4,stream=video,segment_template=h264_1080p_$Number$.ts' \
--ad_cues 600;1800;3000 \
--hls_master_playlist_output h264_master.m3u8
