需要怎么设置MediaCodec的编码参数，比如码流帧率
MediaFormat mediaFormat = MediaFormat.createVideoFormat(MIME_TYPE, 1280, 720);
mediaFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT, mColorFormat);
mediaFormat.setInteger(MediaFormat.KEY_BIT_RATE, BIT_RATE);
mediaFormat.setInteger(MediaFormat.KEY_FRAME_RATE, FRAME_RATE);
mediaFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL,IFRAME_INTERVAL);
mMediaCodec = MediaCodec.createByCodecName(codecInfo.getName());
mMediaCodec.configure(mediaFormat, null, null,MediaCodec.CONFIGURE_FLAG_ENCODE);
在这里设置的format 参数为什么无效， 经过编码后输出的新格式不是Format参数
if (outputBufferIndex == MediaCodec.INFO_TRY_AGAIN_LATER) {
// no output available yet
Log.d(TAG, "no output from encoder available");
} else if (outputBufferIndex == MediaCodec.INFO_OUTPUT_BUFFERS_CHANGED) {
// not expected for an encoder
outputBuffers = mMediaCodec.getOutputBuffers();
Log.d(TAG, "encoder output buffers changed");
} else if (outputBufferIndex == MediaCodec.INFO_OUTPUT_FORMAT_CHANGED) {
// not expected for an encoder
// should happen before receiving buffers, and should only happen once
if (mMuxerStarted) {
throw new RuntimeException("format changed twice");
}
MediaFormat newFormat = mMediaCodec.getOutputFormat();//这一行得到的新的Format不是前面自己设置的参数
Log.d(TAG, "encoder output format changed: " + newFormat);
各位大神， 请指教啊 ！！！！！
