EncoderUtil

public static final int LEVEL_UNSET = -1

A value to indicate the encoding level is not set.

@VisibleForTesting
synchronized public static void clearCachedEncoders()

Clears the cached list of encoders.

public static @Nullable String findCodecForFormat(MediaFormat format, boolean isDecoder)

Finds a MediaCodec that supports the MediaFormat, or null if none is found.

public static int findHighestSupportedEncodingLevel(
    MediaCodecInfo encoderInfo,
    String mimeType,
    int profile
)

Finds the highest supported encoding level given a profile.

public static ImmutableSet<Integer> findSupportedEncodingProfiles(
    MediaCodecInfo encoderInfo,
    String mimeType
)

Returns a set of supported encoding profiles for the given encoder and MIME type.

public static ImmutableList<Integer> getCodecProfilesForHdrFormat(
    String mimeType,
    @C.ColorTransfer int colorTransfer
)

Returns the profile constants that can be used to encode the given HDR format, if supported by the device (this method does not check device capabilities). If multiple profiles are returned, they are ordered by expected level of compatibility, with the most widely compatible profile first.

@RequiresApi(value = 23)
public static int getMaxSupportedInstances(MediaCodecInfo encoderInfo, String mimeType)

Returns the number of max number of the supported concurrent codec instances.

public static Range<Integer> getSupportedBitrateRange(MediaCodecInfo encoderInfo, String mimeType)

Returns the range of supported bitrates for the given MIME type.

public static ImmutableList<Integer> getSupportedColorFormats(MediaCodecInfo encoderInfo, String mimeType)

Returns a list of supported color formats for the given encoder and MIME type.

synchronized public static ImmutableList<MediaCodecInfo> getSupportedEncoders(String mimeType)

Returns a list of encoders that support the given mimeType, or an empty list if there is none.

public static ImmutableList<MediaCodecInfo> getSupportedEncodersForHdrEditing(
    String mimeType,
    @Nullable ColorInfo colorInfo
)

Returns a list of encoders that support HDR editing for the given mimeType and ColorInfo, or an empty list if the format is unknown or not supported for HDR encoding.

public static Range<Integer> getSupportedHeights(
    MediaCodecInfo encoderInfo,
    String mimeType,
    int width
)

Returns a Range of supported heights for the given encoder, MIME type and width.

synchronized public static ImmutableSet<String> getSupportedMimeTypes()

Returns a list of MIME types that can be encoded.

public static @Nullable Size getSupportedResolution(
    MediaCodecInfo encoderInfo,
    String mimeType,
    int width,
    int height
)

Finds an encoder's supported resolution from a given resolution.

The input resolution is returned, if it (after aligning to the encoder's requirement) is supported by the encoder.

The resolution will be adjusted to be within the encoder's range of supported resolutions, and will be aligned to the encoder's alignment requirement. The adjustment process takes into account the original aspect ratio. But the fixed resolution may not preserve the original aspect ratio, depending on the encoder's required size alignment.

public static Pair<Range<Integer>, Range<Integer>> getSupportedResolutionRanges(
    MediaCodecInfo encoderInfo,
    String mimeType
)

Returns a Pair of supported width and height ranges for the given encoder and MIME type.

public static boolean isBitrateModeSupported(
    MediaCodecInfo encoderInfo,
    String mimeType,
    int bitrateMode
)

Returns whether the bitrate mode is supported by the encoder.

public static boolean isFeatureSupported(
    MediaCodecInfo encoderInfo,
    String mimeType,
    String featureName
)

Returns whether a given feature is supported.

public static boolean isHardwareAccelerated(MediaCodecInfo encoderInfo, String mimeType)

Checks if a codec is hardware-accelerated.

public static boolean isSizeSupported(
    MediaCodecInfo encoderInfo,
    String mimeType,
    int width,
    int height
)

Returns whether the encoder supports the given resolution.
