Experimental Analysis for the Best Selection of Video Containers and Codecs.

As the technology is achieving a non-feasible zenith of complexity and quality in video, it is important to maintain the related size of each file at a low level to be able to run the video on devices with limited space like phones. In this regard, different video codecs and containers have been brought forward so that a lower level of information redundancy and processing delay would be sustained. Currently, five codecs namely VP8, VP9, AVC (advanced video compression), and HEVC (High-Efficiency Video Coding) along with three video containers including MP4, MKV (Matroska Multimedia Container), and AVI (Audio-Video Interleaved) are the most considered video compression standards and containers, respectively. Thus, this work aims at the evaluation of these codecs and also their combination with the containers. Moreover, distinct quality metrics that can show the variation lying in between are studied using different metrics. The performance is obtained in terms of PSNR (Peak Signal-To-Noise Ratio), MSE (Mean Squared Error), SSIM (Structural Similarity Index), and VMAF (Video Multi-Method Assessment Fusion) using FFmpeg in Linux distribution to determine the best selection of the codecs and containers.
