Hls and Dash packaging simultaneously with Ffmpeg and Shaka packager

Dash is the open-source equivalent of Apple's HLS technology, used for the same purpose: to deliver live videos or on-demand videos over the web, dynamically changing the quality based on the internet connection of the final user.

HlS it's a standard created by apple in order to deliver audio/video streaming using ordinary web servers.

Following formula will produce a multi-bit-rate version of our master with h264 constrained encoding

Explanation

in : in=your_input_video.mp4, input command
stream : stream=audio for extract only audio file from input file and stream=video for extract only video file from input file

Previously we got different chunk file for different resolution from FFmpeg previous command like 1080.mp4,720.mp4,480.mp4 etc.

For making playlist we have to put respected file one by one

  in=1080.mp4,stream=video,output=h264_1080.mp4,playlist_name=h264_1080p.m3u8,iframe_playlist_name=h264_1080p_iframe.m3u8 \
                                          in=480.mp4,stream=video,output=h264_480p.mp4,playlist_name=h264_480p.m3u8,iframe_playlist_name=h264_480p_iframe.m3u8 \
                                          in=360.mp4,stream=video,output=h264_360p.mp4,playlist_name=h264_360p.m3u8,iframe_playlist_name=h264_360p_iframe.m3u8 \
                                          in=240.mp4,stream=video,output=h264_240p.mp4,playlist_name=h264_240p.m3u8,iframe_playlist_name=h264_240p_iframe.m3u8 \
