Notes:
- The demo app shows up in the launcher as "ExoPlayer"
- The demo app contains a crude adaptive algorithm. It starts at 480p 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 or later, 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.
- The player will attempt to hook into the
AudioTrack.getTimestamp API to do A/V sync. It will fall back to a legacy approach if
the API isn't available.
