配置 MediaCodec 时出错 "Failed to set standard component role 'audio_encoder.aac'"

Question

以下代码用于配置 AAC 编码器：

mfAACEncoder = new MediaFormat();
mfAACEncoder.setString(MediaFormat.KEY_MIME, "audio/mp4a-latm");
mfAACEncoder.setInteger(MediaFormat.KEY_CHANNEL_COUNT, 1);
mfAACEncoder.setInteger(MediaFormat.KEY_SAMPLE_RATE, iClockRateAudio);
mfAACEncoder.setInteger(MediaFormat.KEY_BIT_RATE, 64 * 1024);//AAC-HE 64kbps
mfAACEncoder.setInteger(MediaFormat.KEY_AAC_PROFILE, MediaCodecInfo.CodecProfileLevel.AACObjectLC);

//
mfAACEncoder.setInteger(MediaFormat.KEY_MAX_INPUT_SIZE, 0);

mcAACEncoder = MediaCodec.createDecoderByType("audio/mp4a-latm");
mcAACEncoder.configure(mfAACEncoder, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);

mcAACEncoder.configure() 在 logcat 中生成以下内容：

有人可以提供有关如何解决此问题的提示吗？

如代码所示，the solution of this thread已经实现。

Answer 1

您的问题出在这里：

mcAACEncoder = MediaCodec.createDecoderByType("audio/mp4a-latm");
mcAACEncoder.configure(mfAACEncoder, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);

您想将其用作编码器，但您实际上创建了解码器组件，而是尝试将其用作编码器角色。要修复它，请将第一行改为：

mcAACEncoder = MediaCodec.createEncoderByType("audio/mp4a-latm");

配置 MediaCodec 时出错 "Failed to set standard component role 'audio_encoder.aac'"
