FFMpeg command line to create specific MPD Manifest
22 février 2024, par Seth HabermanI have tried to get an FFMpeg command to yield the below manifest. Right below is the FFmpeg command that I have tried to make but it has not created the same manifest file as what I am trying to replicate a stream from a third party system to add my own stream to their system so that it will actually play back.


"$ffmpeg_path" \
 -i "$input_file" \
 -r 30000/1001 \
 -vf "scale=3840:1080" \
 -c:v libx265 \
 -c:a aac -b:a 128k \
 -ar 48000 \
 -f dash \
 -use_timeline 1 \
 -use_template 1 \
 -init_seg_name "init-stream\$RepresentationID\$.m4s" \
 -media_seg_name "chunk-stream\$RepresentationID\$-\$Number%05d\$.m4s" \
 -seg_duration 3 \
 "$output_file"


The code above yields a manifest that is structured like below.


<?xml version="1.0" encoding="utf-8"?>
<mpd xmlns="urn:mpeg:dash:schema:mpd:2011" profiles="urn:mpeg:dash:profile:isoff-live:2011" type="static" mediapresentationduration="PT1M35.1S" maxsegmentduration="PT3.0S" minbuffertime="PT16.8S">

The problem is that I I need it to create a stream where the manifest looks like the manifest below. If it doesn't look or function as below, it will not playback correctly on this third parties system.
