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.

Videocodec - Videosequence Compression
Bařina, David ; Motlíček, Petr (referee) ; Smrž, Pavel (advisor)
This thesis deals with modern methods of a lossy still image and video compression. Wavelet transformation and SPIHT algorithm also belong to these methods. In second half of this thesis, a videocodec is implemented based on acquired knowledge. This codec uses Daubechies wavelets to analyse an image. Afterwards there is a modified SPIHT algorithm applied on gained coefficients. A lot of effort was put in order to optimize this computation. It is possible to use the created codec in Video for Windows, DirectShow and FFmpeg multimedia frameworks. At the end of this thesis, commonly used codecs are compared with newly created one.

Lossless Video Compression
Němec, Jaroslav ; Polok, Lukáš (referee) ; Bařina, David (advisor)
This master's thesis deals with lossless video compression. This thesis includes basic concepts and techniques used in image representation. The reader can find an explanation of basic difference between lossless video compression and lossy video compression and lossless video compression limitations. There is also possible find a description of the basic blocks forming the video codec (every block is described in detail). In every block there are introduced its possible variants. Implemented lossless videocodec was compared with common lossless videocodecs.

Video Library for Android Platform
Slavotínek, Tomáš ; Polok, Lukáš (referee) ; Láník, Aleš (advisor)
This thesis deals with processing of video content on Android platform. Libraries for video encoding and decoding usable on this platform are described first. One of these libraries - FFmpeg - is used as core to design and implement middleware video-processing library. This library will provide simple but e fective API for multimedia Java applications.

3D Video Browser
Míchal, Vít ; Štancl, Vít (referee) ; Beran, Vítězslav (advisor)
The aim of this project is to design and create application for the visualization of interconnected video data. Visualization takes place in 3D space and seeks to exploit its advantages (such as depth perception). This document contains survey to different categories of spatial user interfaces. In addition, includes three possible designs of user interfaces and control. Implementation details and made usability tests are also described. Application is implemented in C++ using Open Inventor. The document includes evaluation of the results and made tests.

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.

Video Dubbing Tool
Koňárek, Petr ; Soukup, Ondřej (referee) ; Křivka, Zbyněk (advisor)
This thesis deals with draft and implementation of a multi - platform dubbing tool . It is about video and audio processing , recording voice of separate voice actors and its subsequent editing . You can find a set of technologies that are used to solve these tasks and to ensure compatibility with various operating systems . The design is made to include all the necessary audio operations while preserving its simplicity . Finally , you will learn about the testing process of this tool in a fast - dubbing competition and the result of it .

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.

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.

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.
