I have just started using MPEG-DASH (from the client side), following the c057623_ISO_IEC_23009-1_2012 spec.

Does anyone know if there is a public lib or open source to validate MPD file I receive?

I have no problem in processing the xml.

Any help will be appreciated.

You may want to check this MPEG-DASH MPD Validator The DASH Industry Forum provides great software resources for all things MPEG DASH.

    Thanks, this was helpful! I was looking for an open source code that will help me process the code. I have found it in this site - the libdash project. – inbaly Apr 02 '14 at 10:52
  • It's quite interesting for the MPEG-DASH MPD Validator. I tried one .mpd file from dashif (http://www-itec.uni-klu.ac.at/ftp/datasets/mmsys12/BigBuckBunny/MPDs/) but it failed!? – Drake Guan Apr 21 '14 at 09:11
  • @Drake - You are right, I have tried myself few validated mpd files, and they failed, it keeps telling me 'Cannot find the declaration of element ‘MPD'. I think it fails due to the at the start of the file – inbaly Apr 23 '14 at 07:24
  • @Darke - do you have more links to mpd files? I have fond the following examples but could use more: http://dashif.org/reference/players/javascript/1.0.0/index.html http://digitalprimates.net/dash/DashTest.html https://dash-mse-test.appspot.com/dash-player.html – inbaly Apr 23 '14 at 07:59
  • @inbaly You can get a lot .mpd files on Internet. I just noticed if you make all letters non-capital in *xmlns* and *profiles*, some .mpd files can pass this validator ;) – Drake Guan May 02 '14 at 02:45

Here another MPD Validator from dashif: DASHIF Validator.


In respect to the error "Cannot find the declaration of element ‘MPD'" provided by the mentioned MPEG-DASH MPD Validator, I observed it may happen even when the MPD tag is present, but it encounters some differences to the expected text, such as:

<MPD xmlns="urn:mpeg:DASH:schema:MPD:2011" ...>

instead of

<MPD xmlns="urn:mpeg:dash:schema:mpd:2011" ...>
