Cannot play mediaconvert output mpd file

0

Hi, I am using MediaConvert to create output MPEG DASH Here are some jobs 1687829742331-zhrgy3 1687830968695-fvlxbd But the output file .mpd cannot be played by some players such as VLC.

Previously I create output file HLS (m3u8) by job 1687356758035-yeuoq2 and it is played normally without any problem

Could you help with my jobs ?

Hi,

Are you able to play the stream on any mpd players?

It could be an issue with the manifest, or links within the manifest.


Here are a couple of players to test (if you have not already)

https://players.akamai.com/players/dashjs

https://reference.dashif.org/dash.js/latest/samples/dash-if-reference-player/index.html


If you would like other working mpd manifests to compare yours with there are great examples here: https://ottverse.com/free-mpeg-dash-mpd-manifest-example-test-urls/

You can go to the manifest links directly, and not attempt to play them via a player. It will download the manifest and you can open it with notepad, or a similar text editing application.

This will allow you to compare elements of the manifest that may be missing from the output and help to narrow down the issue.


You may want to review your output groups as well, and other output settings to ensure they follow the DASH specific settings.

  • Hi, did you find any solution?

    I'm also facing similar issue. I've compared generated mpd file but in that file <Base URL> is not a url. I'm using s3 bucket for input and output.

    Output in mpd file: <BaseURL>Love Me Like You Do_output2-dash-poc.mp4</BaseURL>

    If you find anything please share some insights here. I'm guessing there is some permission issue

    Thanks

Hi, I am using this extension on chrome to play HLS and MPEG DASH: Native MPEG-Dash + HLS Playback

it plays file m3u8 ok without any problem so I think problem with the generated file mpd. Is there any C# or .NET example to generate the proper MPEG DASH ?

Is the issue input source based? if you use https://test-videos.co.uk/vids/bigbuckbunny/mp4/h264/360/Big_Buck_Bunny_360_10s_1MB.mp4, do you get the same problem? what is your job settings in DASH ISO, Frame rate, GOP and Codec? if you want AWS to look at it, you will need to provide account ID and region, in addition to job ID.
