CDD: Recommend simultaneous decoding of secure streams on Android
Television devices.
Video content providers would like to have 2 secure videos decoded
to improve the transition between titles video playback.
This can't be done today because most Android devices can only
instantiate a single secure decoder at a time.
The industry is not yet ready to adopt this universally but the
requirement is added in Android 8.0 as a STRONGLY RECOMMENDED clause
to signal the intention to introduce a more strict requirement in the
future.

CDD: Latency req. added for Pro audio when 3.5mm audio jack is omitted
We see some device makers omitting the 3.5mm audio jack, the interface
we have previously used to define the audio latency requirement for the
Pro Audio feature.
Hence we're updating the requirement to clarify that the audio latency
in this case should be measured on the USB host port interface.

and H.265 requirements but missed the H.265.

CDD: Remove detail from Raw image decoder requirement
The AOSP provides an implementation of the Raw decoder in Skia
which will display the embedded JPEG (aka "preview") data --
if available in the image file -- or the DNG format data.
The change here removes this implementation detail from the
requirement, as the device implementations may have different
choices for how the Raw image file is decoded.

CDD: Recommend stream-specific adjustment of volume for automotive
Audio management including focus and volume attenuation for
stream ducking is often conducted by an off-board system in
automotive. Android should support individual stream volume
adjustment so that off board mixing and management is handled
correctly in these cases. For some car-specific cases the new
CAR_AUDIO_USAGE_* usages are provided in the android.car API
package.
