you need to setup the StreamingDrmSessionManager object and pass it to the MediaCodecRenderer, inside StreamingDrmSessionManager you need to setup a HttpMediaDrmCallback which define your license url as well as other headers.

How to prepare/encrypt content (on the server-side) is out of scope of this issue tracker. ExoPlayer is only responsible for client side playback. The ExoPlayer demo app demonstrates playback of Widevine protected content, so that and @richardissuperman 's response above should serve as a good starting point.

We are using Test Exoplayer Github code. We edited in media.exolist.json file.
"name": "URL Test 3",
"uri": "https://s3.amazonaws.com/sprngpod/drm/513698_a1dbea8ad80f047a45a4b805d8b8cbb8/mpds/513698.mpd",

but
Video is not playing, it displaying video length only. Please help to find out the error.

that means you loaded the dash manifest(which is normal) , but cant decode or decrypt the data, if the content has been encrypted you have to check the StreamingDrmSessionManager.java, try debug the methods for requesting key and also the callback from MediaDrm.
Noted that you cant just post the drm license url , make sure you/exoplayer include the drmInit Data.

You should also test your content using Shaka Player. Select "custom asset" from the bottom of the asset drop down. If you content doesn't play there either, then something is wrong with your content or license server. This is beyond the scope of this issue tracker. If you have content that plays successfully in Shaka Player but not in ExoPlayer, please let us know.

Hi Richard,

We have downloaded Sample Exo-Player from git-hub
[https://github.com/google/ExoPlayer]

As mentioned in your previous mail we have checked StreamingDrmSessionManager.jav, MediaDrm, httpMediaDrmCallback. In all these methods the below URL, provider getting passed correctly. But video is not playing, only length is getting displayed.

media.exolist.json in the asset folder we have made the below changes. We have doubt whether we are passing the drm license URL is passed correctly. Please check and let us know is the this correct way to send drm license URL as clear stream is playing correctly.

Please don't file identical issues. As per my response above:

If you content doesn't play there either, then something is wrong with your content or license server. This is beyond the scope of this issue tracker.

can you debug the onKeyResponse() method , see if the key response is valid?
