ExoPlayerDemo.apk can be used to do end-to-end verification of your Modular DRM.
To install, side load ExoPlayerDemo.apk app to your device:
adb install ExoPlayerDemo.apk
To run, launch ExoPlayer, then choose the Revenge (DASH CENC) clip, which is encrypted
using DASH Common Encryption. Then press "Play" to start playback. The other clips
in the list are clear (i.e. not encrypted).
Notes:
- The demo app shows up in the launcher as "ExoPlayer"
- The demo app contains a crude adaptive algorithm. It starts at 144p and will not switch up for 15
seconds. This is expected (and has the benefit of more or less guaranteeing there's at least one
switch during any playback beyond this length).
- If your device is running KLP, and the decoder claims to support adaptive, then ExoPlayer will
do seamless resolution switching. If the decoder doesn't claim this then you'll still get the
old nearly-seamless-switch (codec release/re-acquire) behavior.
- If your device is running KLP, the player will attempt to hook into the new
AudioTrack.getTimestamp API to do A/V sync. It will fall back to how it used to do things if
the API isn't available.
- The apk is still built against API level 18. The features above are accessed via reflection.
