Question

我尝试设置个人资料，例如：

MediaCodecInfo.CodecProfileLevel.AVCProfileBaseline

这样的代码段：

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);

但是我收到了以下错误：

我在哪里错过了？

如果您设置了个人资料，则可能还需要设置级别 - 请查看https://android.googlesource.com/platform/frameworks/av/+/6ade04174/media/libstagefright/ACodec.cpp中的setupAVCEncoderParameters。请参阅https://stackoverflow.com/a/26293422/3115956以获取类似的答案以及如何选择要设置为级别的值的说明。
