How Can I Using Privatecodecdata With H264 File In Mediastreamsource

When i use the MediaStreamSource to playback a h264 file, is required that the MediaStreamSource reports to MediaElement that my stream it is ready to start to be send. So, to make it, i need to pass the information about SPS and PPS units of h264 file to CodecPrivateData atribute. However, how can i use it the correct form? How can i convert my decimal data to hex data, with filling this field of correct way?

Microsoft describes that:

CodecPrivateData Example: 0x00000001 SequenceParameterSet 0x00000001 PictureParameterSet
for example: "00000001674D401E965201405FF2E020100000000168EF3880"

And below have the SPS and PPS infos:

How can i pass this data to the form that microsoft describes?
