Expected Data Format for VpuBufferNode VPU Wrapper

I'm using an IMX.8MP trying to use the VPU Wrapper. I have a RTP stream of H.264 Encoded Video of Fragmented FU-A NALU's along with SPS and PPS NALUs. The stream is non-interleaved with the fragmented NALU's having a nal_unit type of 5 (coded slice of an IDR picture). How should I process the stream data into the VpuBufferNode to then decode. I've tried removing the first 12 bytes which represent the RTP header info and passing the rest into the decoder. Ive been reading RTP Payload Format for H.264 Video which says I should preform a de-packetization process in which I concatenate the fragmented FU payloads of a fragmented NALU together and then send that to the decoder. Is that what I should be assigning to the VpuBufferNode? Also how would I process SPS and PPS NALUs and to send to the decoder?

Hello,

Sorry no SPS and PPS form MX8 VPU, may be useful to look at updated for i.MX8
