Rgd retrieving the DRM specific information from Dash MPD

[Sanjay Gupta]

Hi,
I have a Dash content with DRM specific information present in dash mpd file e.g.
            <ContentProtection schemeIdUri="urn:mpeg:dash:mp4protection:2011" value="cenc" cenc:default_KID="10000000-1000-1000-1000-100000000001"/>
            <ContentProtection schemeIdUri="urn:uuid:9a04f079-9840-4286-ab92-e65be0885f95" value="2.0" cenc:default_KID="10000000-1000-1000-1000-100000000001">
                     <mspr:pro>ngMAAAEAAQCUAzwAVwBSAE0ASABFAEEARABFAFIAIAB4AG0AbABuAHMAPQAiAGgAdAB0AHAAOgAvAC8AcwBjAGgAZQBtAGEAcwAuAG0Aa ....</mspr:pro>
            </ContentProtection>

Dashdemux is parsing the ContentProtection element and sending GST_EVENT_PROTECTION event down stream with GstBuffer holding the information mentioned  in 'value' attribute of contentprotection element e.g. '2.0' in this case, with origin as "dash/mpd".
does dashdemux parse the information present inside "mspr:pro" element in ContentProtection element also in this case? I don't see it sending the event with this base64 encoded DRM specific information?

How to retrieve this DRM specific information present in MPD? Thanks for your input/suggestion.

Thanks & Regards,
Sanjay

You'll have to add support for exposing the PlayReady relevant
information to dashdemux. It should probably be provided with the
content protection event too.

If you add support for that, please provide your patch in Bugzilla. We
can merge it then and you'll have it available in all future GStreamer
releases.
