Audio/video streaming
Čeněk, Radek ; Jeřábek, Jan (referee) ; Číka, Petr (advisor)
This thesis introduces the reader in detail with the problem of audio / video streaming overtheInternet.IntroducestechnologiesMySQL,PHP,JavaScriptandffmpegfurthermore. There is little research which examines presented similar solutions. Creating video library program shows the complexity of the problem and its possible solution. The work also finding how is compression difficult for the server.

Video Editor For Android Platform
Vyoral, Marek ; Zuzaňák, Jiří (referee) ; Láník, Aleš (advisor)
Main goal of this thesis is implementation of a simple video editing application for Android platform. In the theoretical part are described present-day possibilities of video editing on computers and mentioned also existing applications for Android. Then the platform itself and its features are described with focus to development of applications, especially native ones. The FFmpeg library for multimedia processing is described next. It was used in implementation of application. The next part of thesis considers with implemented application and describes its design, structure, user interface and process of implementation. Then the results of video processing performance tests and their evaluation are presented. In the end is the application compared with similar existing applications.

Vehicle Speed Estimation from Video
Hájek, Pavel ; Herout, Adam (referee) ; Juránek, Roman (advisor)
This master's thesis describes design and development of an application for estimation of vehicle speed from both recorded video file and from camera stream. It explains the procecess of a camera calibration, vehicle detection and tracking and describes the robot operating system as a target platform. The application uses library OpenCV for most of tasks, to access video application uses a FFmpeg library. Results can be printed to the terminal window, they can also be logged to a file or published in ROS. Application is written in C++ language, some parts in Python.

Compression, decompression and streaming of video data
Šilhavý, Miroslav ; Číka, Petr (referee) ; Burget, Radim (advisor)
The Bachelor thesis is focused on description of FFmpeg tool and theora codec abilities. Comparison of capabilities and technologies within MPEG-4 (MPEG4- ASP, H.264), Theora and MPEG-2 codec. Testing the compression efficiency and output image quality of codecs x264 and Theora. Further I mentioned samples of using Theora and FFmpeg programming interface for video handling. Part of the thesis is also analysis and implementation of the player based on FFmpeg libraries and application for streaming Theora encoded video packets by RTP protocol.

IP Cameras Control Library
Schmied, Jan ; Rozman, Jaroslav (referee) ; Luža, Radim (advisor)
This thesis describes the design and implementation of a library that allows control of IP cameras and receives multimedia streams. The thesis briefly introduces standard interfaces of IP cameras and describes in detail VAPIX interface. This interface is also demonstrated by examples. The practical part deals with the design and implementation of the library using the FFmpeg and cURL libraries. Library is subject of a measurement that shows its performance.

Audio and video streaming using real-time protocol
Křenek, Tomáš ; Schimmel, Jiří (referee) ; Burget, Radim (advisor)
This diploma thesis focus on transmiting multimedia over computer network. There are detailed informations about protocols RTP and RTPC in a first part because a transmition over a network is realized by using these protocols. Some basic multimedia terms, FFmpeg codecs and SDL library are described in next chapters. A multimedia player using FFmpeg and SDL is implemented in a second part of thesis. The player is console application and it has basic user interface. The player reproduces video and audio from a given file. RTP communication is described in next chapters of the second part. RTP server and client are implemented there too. They are console aplications and they use data coded by Theora or Vorbis. There are summarized results in a conclusion.

Smart Video Doorbell Based on Raspberry Pi
Ondrejka, Adam ; Zemčík, Pavel (referee) ; Materna, Zdeněk (advisor)
This thesis is focused on the design and implementation of a smart doorbell based on Raspberry Pi. Unlike commercially available smart doorbells, the solution described in this thesis offers full functionality (motion detection, audiovisual streaming, and notifications) even without internet access. The doorbell operates fully locally and enables the user to use more doorbells at the same time. A web page and desktop app for displaying notifications was also implemented for the doorbell. After connecting to the android app Gotify, notifications can also be delivered to a device with the Android operational system.

Application for Video Tracking
Borek, Martin ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
Předložená bakalářská práce pojednává o implementaci aplikace Video Anonymizer. Tato aplikace sleduje objekty ve videu a upravuje jejich vzhled. Práce se zabývá zpracováním videa s použitím knihovny FFmpeg, kde se zaměřuje především na vyhledávání snímků. Soustřeďuje se také na sledování více objektů, úpravu jejich trajektorií a na jejich anonymizaci; upřednostňovaný způsob anonymizace je rozmazání objektu. Dále je zde rozebráno vytváření vícejazyčného uživatelsky přívětivého grafického uživatelského rozhraní s pomocí knihovny QT. Při testování uživatelské přívětivosti tohoto grafického uživatelského rozhraní bylo zjištěno, že aplikace je snadno ovladatelná již při jejím prvním použití. Také bylo ověřeno, že uživatelská nápověda obsahuje všechny potřebné informace a je snadno dostupná přímo z aplikace.

Rotational 3D scanner
Švehla, Ľubomír ; Polák, Ladislav (referee) ; Kaller, Ondřej (advisor)
The point of this project is to design and construct a rotational 3D scanner. It is both about the hardware and software part. Low construction price is important factor in the hardware part and therefore the hardware part is really simple. Software part is solved by the FFmpeg tool and programming environment MATLAB. From the selected number of frames from the synchronized video the irradiated part is segmented. Consequently by compositing these traces a 3D model is gained. To gain a better result, the program uses two cameras. Program can be fully controlled from GUI.
