ExoPlayerDemo.apk can be used to do end-to-end verification of Modular DRM.
To install, side load ExoPlayerDemo.apk app to your device:
adb install ExoPlayerDemo.apk
To run, launch ExoPlayer, then choose the clip to play. The
Widevine-encrypted DASH CENC assets are in the "WIDEVINE DASH GTS"
section.
These assets test various configurations of the Key Control Block (KCB)
with various protections and expirations:
WV: HDCP not specified (KCB: Observe_HDCP=false)
WV: HDCP not required (KCB: Observe_HDCP=true && HDCP=not required && DataPath=normal)
WV: HDCP required (KCB: Observe_HDCP=true && HDCP=required && DataPath=normal)
WV: Secure video path required (KCB: Observe_HDCP=true && HDCP=not required && DataPath=secure)
WV: HDCP + secure video path required (KCB: Observe_HDCP=true && HDCP=required && DataPath=secure)
WV: 30s license duration (KCB: test timer expiration)
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.
- Exoplayer will retrieve a new license when playing "WV: 30s license duration",
after the license duration has expired. Integrators should verify by means
other than visual inspection that license duration is being enforced.
