native code encoder

[manoj soni]

Hi,

I am trying to use media codec in ndk for hardware encoding. I am referring to the sample native-codec in the new android ndk release. I get failure while I try to configure the encoder. Below are my configuration parameter. I would really appreciate if I can get any help to figure out what could be the problem. 

              

        encoder = AMediaCodec_createEncoderByType("video/avc");

        AMediaFormat *encformat = AMediaFormat_new();

AMediaFormat_setInt64(encformat,AMEDIAFORMAT_KEY_BIT_RATE,125000);

AMediaFormat_setFloat(encformat,AMEDIAFORMAT_KEY_FRAME_RATE,15.0);

AMediaFormat_setInt64(encformat,AMEDIAFORMAT_KEY_COLOR_FORMAT,0x00000013);

AMediaFormat_setInt32(encformat,AMEDIAFORMAT_KEY_WIDTH,352);

AMediaFormat_setInt32(encformat,AMEDIAFORMAT_KEY_HEIGHT,288);

AMediaFormat_setInt32(encformat,AMEDIAFORMAT_KEY_MAX_WIDTH,352);

AMediaFormat_setInt32(encformat,AMEDIAFORMAT_KEY_MAX_HEIGHT,288);

AMediaFormat_setInt32(encformat,AMEDIAFORMAT_KEY_I_FRAME_INTERVAL,5);

AMediaFormat_setInt32(encformat,AMEDIAFORMAT_KEY_STRIDE,352);

AMediaFormat_setString(encformat,AMEDIAFORMAT_KEY_MIME,"video/avc");

      AMediaCodec_configure(encoder,encformat,NULL,NULL,AMEDIACODEC_CONFIGURE_FLAG_ENCODE);

following is the error that I get [OMX.qcom.video.encoder.avc] configureCodec returning error -38.  I am not sure what error -38 means. Also I would like to know if there is any way we can get verbose log from ACodec.Cpp file (any file inside stage fright code). 

Thanks,

Hi, sorry for late response, but in case if it's still important for someone the answer is: you should use AMediaFormat_setInt32 instead of AMediaFormat_setInt64 in all this methods.
