MPEG-DASH Media Presentation Description

An MPD file is a text file that describes how an MPEG-DASH video is streamed. It contains XML-formatted text that a web client uses to deliver .M4S (or other) streamed videos to Internet users. MPD files define streamed videos' segment duration, codec, MIME type, maximum dimensions, and other settings.

MPEG-DASH is an adaptive bitrate streaming technique that allows users to stream high-quality video over the Internet using HTTP. Videos streamed using MPEG-DASH are divided into segments, which allows web clients to stream long videos without stalling or re-buffering.

MPD files define how a video streamed using MPEG-DASH is divided into segments and shown to users. While different MPD files contain different formatting and settings, all MPD files are XML files. They all also include the <MPD>, <Period>, <AdaptationSet>, <Representation>, and <SegmentTemplate> elements, which are used as follows:

  • <MPD>: Defines the streamed video's profile, minimum buffer time, total duration (if known), and segment duration
  • <Period>: Defines the streamed video's chapters and chapter duration
  • <AdaptationSet>: Defines the streamed video's alignment, maximum dimensions, maximum frame rate, language, and content type
  • <Representation>: Defines the resolutions and bitrates at which the streamed video is available
  • <SegmentTemplate>: Defines the time offset and duration of the streamed video's segments

Come aprire un file MPD

You can use VideoLAN VLC media player to open an MPD file and play the video to which it points. If your MPD file is available at a URL, use the following instructions. Otherwise, open the file as you would normally.

  1. In VLC, select either Media → Open Network Stream (Windows, Linux) or File → Open Network... (Mac).
  2. Paste your MPD file's URL into the URL field.
  3. Select Play or Open.

Note that if the MPD file you are attempting to open is formatted incorrectly, or the video to which it points is no longer available, VLC will not play any video after you open your file.

You can also use yt-dlp, a command-line program, to download the video to which an MPD file points. To do so, use the following command (after installing yt-dlp):

yt-dlp -f https://URL/for/YourFile.mpd

Additionally, because MPD files are XML files, you can open them in any text or source code editor, including:

Doing so allows you to view and/or edit the file's text contents. Opening an MPD file in a source code editor will highlight the file's XML syntax, making its text easier to understand and edit.

Melodyne Project

An MPD file is a project file created by Melodyne, an audio pitch correction tool. It contains a record of the edits a user has made to an accompanying audio file. It also contains a reference to the audio file's location, which Melodyne uses to load the file before applying edits to it.

Maggiori informazioni

Audio producers use Melodyne to correct or otherwise modify an audio track's pitch and timing. Most commonly, producers use Melodyne to edit vocal tracks imported from a DAW. They then export the tracks back to their DAW for further editing, as part of a complete song.

When editing a track in Melodyne, producers can save their project as an MPD file. Doing so preserves the original audio file they are editing. This allows producers to easily revert changes they've made to the original file. In contrast, if a producer chooses to export their edited audio file as a .WAV or .AIF file, they cannot revert the edited file to its original state. They also must reimport the file into Melodyne and create a new project if they want to make further edits.

Come aprire un file MPD

You can open an MPD file in Celemony Melodyne (Windows, Mac). To do so, select File → Open from the program's menu bar. If the audio file your MPD file references is missing, Melodyne will prompt you to update the path to the audio file.

Come convertire un file MPD

You can use Melodyne to export the audio project an MPD file contains as a .WAV or .AIF file. To do so, open your MPD file, and then select File → Export... from the program's menu bar.
