Title: Super-Resolution Online Video Transmission System using FFmpeg and RTSP Protocol

Abstract

This paper presents an online video transmission system for super-resolution using FFmpeg and RTSP protocol. The system involves transmitting low-resolution video streams from the server to edge nodes, where super-resolution processing is performed. The system is implemented using FFmpeg, a powerful multimedia framework that encodes, decodes, and transmits multimedia data. The RTSP protocol is used for video streaming, providing real-time capabilities for live video transmission.

Introduction

The proposed system is designed for online video transmission, involving real-time transmission of low-resolution video streams from the server to edge nodes. Super-resolution techniques are then applied to improve the video quality. The system utilizes FFmpeg, a multimedia framework offering tools for encoding, decoding, and transmitting multimedia data. The RTSP protocol, a real-time protocol, enables live video streaming.

FFmpeg as a Tool

FFmpeg is a powerful multimedia framework providing tools for encoding, decoding, and transmitting multimedia data. Its versatility and flexibility make it widely used in the multimedia industry. In our system, FFmpeg encodes and transmits low-resolution video streams from the server to edge nodes. FFmpeg's lightweight nature allows easy integration into any system, making it an ideal choice for our project.

RTSP Protocol

The RTSP protocol is used for video streaming, providing a real-time protocol for live video streaming. It offers a reliable and efficient method for transmitting video streams over the network. In our system, the RTSP protocol transmits low-resolution video streams from the server to edge nodes. The RTSP protocol ensures real-time video transmission without delay, crucial for our system.

Reducing Bandwidth Pressure

Two commands are used in our system to reduce bandwidth pressure. The first command on the server is '-vf scale=iw/2:ih/2', which scales down the video to half its original size, reducing the size of the video stream and bandwidth pressure. The second command on the edge device is '-c:v copy -c:a copy -flags +global_header -f segment -segment_time 10 -segment_format mp4 -reset_timestamps 1 -strftime 1', which segments the video into smaller segments. This reduces the size of each segment, further reducing bandwidth pressure.

Conclusion

The proposed online video transmission system for super-resolution using FFmpeg and RTSP protocol provides a reliable and efficient solution for transmitting low-resolution video streams from the server to edge nodes. The use of FFmpeg as a tool and the RTSP protocol for video streaming ensures real-time video transmission without delay. The system also includes commands to reduce bandwidth pressure, making it an ideal solution for real-time video transmission.
