        Returns a list of MIME types that can be encoded.

      • clearCachedEncoders

        public static void clearCachedEncoders()
        Deprecated.
        Clears the cached list of encoders.

      • getSupportedEncodersForHdrEditing

        public static ImmutableList<MediaCodecInfo> getSupportedEncodersForHdrEditing​(String mimeType,
                                                                              @Nullable

        Deprecated.
        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.

      • getCodecProfilesForHdrFormat

        public static ImmutableList<Integer> getCodecProfilesForHdrFormat​(String mimeType,
                                                                  @com.google.android.exoplayer2.C.ColorTransfer int colorTransfer)
        Deprecated.
        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.

      • isSizeSupported

        public static boolean isSizeSupported​(MediaCodecInfo encoderInfo,
                                      String mimeType,
                                      int width,
                                      int height)
        Deprecated.
        Returns whether the encoder supports the given resolution.

      • getSupportedResolution

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

        Parameters:
        encoderInfo - The MediaCodecInfo of the encoder.
        mimeType - The output MIME type.
        width - The original width.
        height - The original height.
        Returns:
        A supported resolution, or null if unable to find a fallback.

      • findHighestSupportedEncodingLevel

        public static int findHighestSupportedEncodingLevel​(MediaCodecInfo encoderInfo,

                                                    int profile)
        Deprecated.
        Finds the highest supported encoding level given a profile.
        Parameters:
        encoderInfo - The encoderInfo.
        mimeType - The MIME type.
        profile - The encoding profile.
        Returns:
        The highest supported encoding level, as documented in MediaCodecInfo.CodecProfileLevel, or LEVEL_UNSET if the profile is not supported.

        public static boolean isHardwareAccelerated​(MediaCodecInfo encoderInfo,
                                            String mimeType)
