hevc compression matlab implementation

hi;
can anyone please help me with the reading of the binary stream generated by the HEVC encoder into matlab ??

The HEVC standard (H.265) is the most advanced enhanced video encoding standard, which was planned to improve the rendered specifications of its earlier MPEG-4 (H.264) standard. According to H.265 "The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards - in the 50% reduction of bit rate range for equal perceptual video quality" . Intra-image prediction is a tool in HEVC that "uses some prediction of data spatially from region to region within a specific image, but has no dependence on other images in video frames" . Intra-image prediction of HEVC is the legacy of the intra-frame prediction tool in H.264. Although both have the same focus on spatial prediction of images based on prediction of spatial sample followed by coding transformation, H.265 intra-frame prediction uses much more developed features compared to H.264. An overview of the main features of the intra-frame prediction of H.265 could be written as follows:  A block-division structure of blocks with respect to the amount of detail in an image  33 Angular modes in prediction Angular (only 8 different modes in H.264)  Planar prediction to smooth sample surfaces  It is worth mentioning that the intra-H.265 quad-tree structure normally uses square block with sizes in the range 4, 8, 16, 32 and 64 sizes based on the level of granularity in the image), while in H.264 the processing units are up to macro-blocks of 16x16 samples. On the other hand, while this standard video encoding splits the images of a luma and two parts of chrominance, the thesis focuses only on the application of the intra-prediction in a part of an image. This thesis aims to implement the intra-frame prediction of HEVC using MATLAB. All steps of the implementation process are as follows: 
 Convert RGB images to YUV color space and work in the luma (or Y) part 
 Split images to square blocks of 4 to 64 pixels 
 Implement a prediction algorithm Intra-frame 
 Comparison of intra-prediction production of H.264 and H.265 in square blocks with size 4 and 16 pixels This thesis is organized in 3 main sections. 
The first and second sections revolve around the literature review and the definition of the concept of standard HEVC and intra-prediction, respectively. The third section focuses on the implementation process and the evaluation of the prediction algorithm. Finally, in the evaluation part, based on statistical graphs derived from the comparison of H.264 output and H.265 intra-prediction for different images, it has been shown that H.265 has, by far, a better quality of Image than the H.264.
