fun getSupportedDynamicRanges(): (Mutable)Set<DynamicRange!>

Gets all dynamic ranges supported by both the camera and video output.

Only DynamicRanges with specified values both in DynamicRange.BitDepth and DynamicRange.DynamicRangeEncoding will be present in the returned set. DynamicRanges such as HDR_UNSPECIFIED_10_BIT will not be included, but they can be used in other methods, such as checking for quality support with isQualitySupported.

fun getSupportedQualities(dynamicRange: DynamicRange): (Mutable)List<Quality!>

Gets all supported qualities for the input dynamic range.

The returned list is sorted by quality size from largest to smallest. For the qualities in the returned list, with the same input dynamicRange, isQualitySupported will return true.

When the dynamicRange is not fully specified, e.g. HDR_UNSPECIFIED_10_BIT, the returned list is the union of the qualities supported by the matching fully specified dynamic ranges. This does not mean that all returned qualities are available for every matching dynamic range. Therefore, it is not recommended to rely on any one particular quality to work if mixing use cases with other dynamic ranges.

Note: Constants HIGHEST and LOWEST are not included in the returned list, but their corresponding qualities are included. For example: when the returned list consists of UHD, FHD and HD, HIGHEST corresponds to UHD, which is the highest quality, and LOWEST corresponds to HD.

fun isQualitySupported(quality: Quality, dynamicRange: DynamicRange): Boolean

Checks if the quality is supported for the input dynamic range.

Calling this method with one of the qualities contained in the returned list of getSupportedQualities will return true.

Possible values for quality include LOWEST, HIGHEST, SD, HD, FHD and UHD.

If this method is called with LOWEST or HIGHEST, it will return true except the case that none of the qualities can be supported.

When the dynamicRange is not fully specified, e.g. HDR_UNSPECIFIED_10_BIT, true will be returned if there is any matching fully specified dynamic range supporting the quality, otherwise false will be returned.

fun isStabilizationSupported(): Boolean

Returns if video stabilization is supported on the device. Video stabilization can be turned on via setVideoStabilizationEnabled.

Not all recording sizes or frame rates may be supported for stabilization by a device that reports stabilization support. It is guaranteed that an output targeting a MediaRecorder or MediaCodec will be stabilized if the recording resolution is less than or equal to 1920 x 1080 (width less than or equal to 1920, height less than or equal to 1080), and the recording frame rate is less than or equal to 30fps. At other sizes, the video stabilization will not take effect.
