In my i want encode yuv data into h264 using mediacodec software codec.
I use Google software encoder OMX.google.h264.encoder
when i use hardware encoder[OMX.qcom.video.encoder.avc] that time it work but when i use software encoder[OMX.google.h264.encoder] it not encode file.it will give error [see in log].
what is problem i couldn’t identify.
Source :
mediaCodec = MediaCodec.createByCodecName("OMX.google.h264.encoder");
//mediaCodec = MediaCodec.createByCodecName(codecInfo.getName());
Log.i(TAG,"codec name : "+ mediaCodec.getName());
int mBitrate = (int) ((MainActivity.mHeight * MainActivity.mWidth * MainActivity.frameRate)*2*0.07);
MediaFormat mediaFormat = MediaFormat.createVideoFormat("video/avc",MainActivity.mWidth,MainActivity.mHeight);
mediaFormat.setInteger(MediaFormat.KEY_BIT_RATE,mBitrate);
mediaFormat.setInteger(MediaFormat.KEY_FRAME_RATE, MainActivity.frameRate);
// mediaFormat.setInteger(MediaFormat.KEY_MAX_INPUT_SIZE, 320*240);
mediaFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT,colorFormat);
//mediaFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT,MediaCodecInfo.CodecProfileLevel.AVCLevel12);
mediaFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL,1);
try{
mediaCodec.configure(mediaFormat, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);
mediaCodec.start();
Log.i(TAG,"H264 Encoder init success");
}catch(IllegalArgumentException e)
{
e.printStackTrace();
}catch (IllegalStateException e) {
e.printStackTrace();
}catch (Exception e) {
e.printStackTrace();// TODO: handle exception
}
But i getting this error.

The SW encoder OMX.google.h264.encoder is very limited at the moment (edit: On Android 5.0), close to being unusable.
This encoder doesn't allow using resolutions that aren't a multiple of 16. In your case, 1920x1080, the height 1080 isn't evenly dividable by 16, and thus isn't acceptable for this encoder. (See https://android-review.googlesource.com/38904 for an attempt at fixing this.)
If you'd change it into 1088, the multiple-of-16 wouldn't be an issue, but the encoder also won't allow you to use it with any resolution above 352x288 (see e.g. https://android-review.googlesource.com/82133).
Finally, on older Android versions (prior to 5.0), it also did output in a slightly different format (missing startcodes, see https://android-review.googlesource.com/42321), which meant that you would have to manually add startcodes at the start of each output packet to be able to use them in certain places (the MediaMuxer might have handled it as it was, though, mostly by chance).
In the current AOSP master (that is, maybe in the next major release, unless that already is being finalized and this change hasn't been included there), the encoder has been replaced with a more capable one, but for existing releases, there's not much you can do other than bundling a better SW encoder within your app.
Edit: The Android M preview that was released today does include the new SW encoder, which should work fine for this usecase.
Edit2: The new encoder was included in the Android 6.0 release (M), so since then, it should be usable.
