Decode H.264 stream and display in Unity

I'm trying to do raw decoding of H.264 stream, whose packages I'm getting from an active UDP connection those are groups of 4 packages which are making an buffer which is representing one video frame. I don't know much about H.264 decoding but I'm trying to have input which is accepting mentioned buffer from UDP connection, decoding it and applying it to the texture inside Unity.

I tried following things: - Vive Media Decoder asset (https://assetstore.unity.com/packages/tools/video/vive-media-decoder-63938), it's doing great job while working with protocols like rtmp, rtsp etc. but for raw decoding from incoming buffer can't do much as it's wrapped around ffmpeg and other decoding tools - C written H.264 decoder (https://github.com/shengbinmeng/ffmpeg-h264-dec), depends on many libav libraries which I'm unable to track and adjust and later than convert into .dll which will be accessible from C# inside Unity - C++ written H.264 decoder (https://www.roxlu.com/2014/039/decoding-h264-and-yuv420p-playback), similar as above I'm getting compile time errors for unkown functions which again depends on libav/ffmpeg libraries - C# written H.264 decoder (https://github.com/pansk/cscodec), seems to be working with url's but still not sure if I could send buffer direct to it and not sure how to include whole visual studio c# project into unity project and make it work - Also I have looked at https://github.com/Ruslan-B/FFmpeg.AutoGen but was unable to find a way to solve my problem

Basiclly, what I'm looking for is an written .dll (C/C++ program) file which is accepting H.264 encoded frames (buffers) and returning RGB array, which is used and called inside Unity project.
