Abstract
U ovom diplomskom radu izrađena je web aplikacija/poslužitelj za strujanje videosignala korištenjem HLS protokola. Aplikacija je izrađena korištenjem Django web radnog okvira u Python programskom jeziku. U aplikaciji je omogućena prijava registriranih korisnika i registracija novih korisnika prije nego li se pristupi stranici za gledanje videozapisa. Segmenti videa i manifest datoteka HLS strujanja generirani su iz videa dohvaćenog s web kamere korištenjem ffmpeg alata te ih HLS reproduktoru Nginx web poslužitelj poslužuje kao statičke datoteke. Većina aplikacije se poslužuje putem Gunicorn WSGI poslužitelja koji prima korisničke zahtjeve od Nginx poslužitelja i prosljeđuje ih Django aplikaciji. Prijava i registracija korisnika odrađena je korištenjem ugrađenog Django-ovog sustava autentikacije s izmijenjenim modelom korisnika. Za osvježivanje liste aktivnih korisnika na stranici za strujanje uvedena je asinkrona komunikacija pomoću Django kanala i WebSocket protokola. Nakon toga aplikacija je implementirana na računalo Raspberry Pi 3 s izmijenjenim kodom za generiranje strujanja zbog lošijih performansi Raspberry-ja. Također je implementirano MPEG-DASH strujanje kako bi se napravila usporedba dvaju protokola. Izmjereno je kašnjenje i varijacija kašnjenja te rezultati pokazuju da HLS strujanje ima otprilike duplo manje kašnjenje nego MPEG-DASH strujanje dok varijacije kašnjenja imaju slične vrijednosti.
Abstract (english)
In this master's thesis, a web application/server for streaming video signals using the HLS protocol was developed. The application was built using the Django web framework in the Python programming language. The application allows registered users to log in and new users to register before accesing the video streaming page. Video segments and HLS streaming manifest files were generated from video captured from a webcam using the ffmpeg tool, and the Nginx web server serves them as static files to the HLS player. Most of the application is served through the Gunicorn WSGI server, which receives user requests from the Nginx server and forwards them to the Django application. User login and registration were implemented using the built-in Django authentication system with a modified user model. Asynchronous communication using Django Channels and the WebSocket protocol was introduced to refresh the list of active users on the streaming page. Afterward, the application was implemented on a Raspberry Pi 3 computer with modified streaming code due to the Raspberry Pi's lower performance. MPEG-DASH streaming was also implemented to compare the two protocols. Delay and jitter were measured, and the results show that HLS streaming has approximately half the delay compared to MPEG-DASH streaming, while jitter has similar values.
