如何设置 Android MediaCodec 配置文件？

Question

我正在尝试设置配置文件，例如：

MediaCodecInfo.CodecProfileLevel.AVCProfileBaseline

这样的代码片段：

MediaFormat format = MediaFormat.createVideoFormat(MIME_TYPE, config.getWidth(), config.getHeight());
format.setInteger(MediaFormat.KEY_COLOR_FORMAT,
        MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface);
format.setInteger(MediaFormat.KEY_BIT_RATE, config.getBitrate());
format.setInteger(MediaFormat.KEY_FRAME_RATE, config.getHumanFPS());
format.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, config.getIFrameInterval());
format.setInteger(MediaFormat.KEY_PROFILE, MediaCodecInfo.CodecProfileLevel.AVCProfileBaseline);

mEncoder = MediaCodec.createEncoderByType(MIME_TYPE);
mEncoder.configure(format, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);

但是我得到了以下错误：

我哪里漏了？

如果您设置配置文件，您可能还需要设置级别 - 查看 https://android.googlesource.com/platform/frameworks/av/+/6ade04174/media/libstagefright/ACodec.cpp. See 中的 setupAVCEncoderParameters 以获得类似的答案以及如何选择一个值的解释设置为级别。
