Remarks
ApplicationMediaCapabilities is an immutable class that encapsulates an application's capabilities for handling newer video codec format and media features.
Android 12 introduces Compatible media transcoding feature. See Compatible media transcoding. By default, Android assumes apps can support playback of all media formats. Apps that would like to request that media be transcoded into a more compatible format should declare their media capabilities in a media_capabilities.xml resource file and add it as a property tag in the AndroidManifest.xml file. Here is a example:
{@code
<media-capabilities xmlns:android="http://schemas.android.com/apk/res/android">
<format android:name="HEVC" supported="true"/>
<format android:name="HDR10" supported="false"/>
<format android:name="HDR10Plus" supported="false"/>
</media-capabilities>
}
The ApplicationMediaCapabilities class is generated from this xml and used by the platform to represent an application's media capabilities in order to determine whether modern media files need to be transcoded for that application. </p>
ApplicationMediaCapabilities objects can also be built by applications at runtime for use with ContentResolver#openTypedAssetFileDescriptor(Uri, String, Bundle) to provide more control over the transcoding that is built into the platform. ApplicationMediaCapabilities provided by applications at runtime like this override the default manifest capabilities for that media access.The object could be build either through #createFromXml(XmlPullParser) or through the builder class ApplicationMediaCapabilities.Builder<h3> Video Codec Support</h3>
Newer video codes include HEVC, VP9 and AV1. Application only needs to indicate their support for newer format with this class as they are assumed to support older format like h.264.
<h3>Capability of handling HDR(high dynamic range) video</h3>
There are four types of HDR video(Dolby-Vision, HDR10, HDR10+, HLG) supported by the platform, application will only need to specify individual types they supported.
