Method Detail

• getSupportedEncoders

  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.

• getSupportedVideoMimeTypes

  public static ImmutableSet<String> getSupportedVideoMimeTypes()

  Returns a list of video MIME types that can be encoded.

• isSizeSupported

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

  Returns whether the encoder supports the given resolution.

• getSupportedHeights

  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.

  Throws:

  IllegalArgumentException - When the width is not in the range of supported widths.

• getSupportedResolutionRanges

  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.

• getSupportedResolution

  @Nullable
  public static 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.

  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.

• findSupportedEncodingProfiles

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

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

• findHighestSupportedEncodingLevel

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

  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.

• findCodecForFormat

                                          boolean isDecoder)

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