the class MediaCodecAudioRenderer method getDecoderInfos.

/**
 * Returns a list of decoders that can decode media in the specified format, in the priority order
 * specified by the {@link MediaCodecSelector}. Note that since the {@link MediaCodecSelector}
 * only has access to {@link Format#sampleMimeType}, the list is not ordered to account for
 * whether each decoder supports the details of the format (e.g., taking into account the format's
 * profile, level, channel count and so on). {@link
 * MediaCodecUtil#getDecoderInfosSortedByFormatSupport} can be used to further sort the list into
 * an order where decoders that fully support the format come first.
 *
 * @param mediaCodecSelector The decoder selector.
 * @param format The {@link Format} for which a decoder is required.
 * @param requiresSecureDecoder Whether a secure decoder is required.
 * @param audioSink The {@link AudioSink} to which audio will be output.
 * @return A list of {@link MediaCodecInfo}s corresponding to decoders. May be empty.
 * @throws DecoderQueryException Thrown if there was an error querying decoders.
