VADecoder cannot preperly decode VAEncoder output

[danylosadivnychyi]

I'm playing around with D3D12HelloVAEncode/VADecode. Both seem to be working without crashes, but whenever I write the encoded bitstream to .h264 file, the VLC reader cannot seem to read it. Also if I read this bitstream in VAEncode and load the data to the VA_H264DEC_BUFFER_INDEX_COMPRESSED_BIT buffer in VADecode, it just shows me some gibberish on the screen (I changed the window resolution resolution in Main.cpp). @sivileri attached the image decoder produces on the screen for me.
