This document describes a MATLAB simulation of Matroska video streaming. It encodes two CIF videos in H.264/AVC format wrapped in MKV containers, extracts metadata from the encoded files, runs a simulation by introducing packet losses, decodes the received files to RAW video, and compares the original and received videos using PSNR measurements. Key steps include encoding the videos with x264, extracting metadata with mkvinfo, running the simulation with mkv_sim_demo.m and various support files, decoding with ffmpeg, and measuring PSNR with yuv_psrn.m. Plots of PSNR vs loss percentage for I, P, and B frames show PSNR decreasing with higher losses, and stefvideo tools
