【摘要】：隨著智能手機在人們生活中的廣泛應(yīng)用,一些過去人們不敢想的夢想變成現(xiàn)實�？萍嫉陌l(fā)展無疑是“中國夢”的重要動力,而智能手機在科技發(fā)展中無疑也扮演著重要的角色。在過去短短的幾年里,智能手機的信息處理能力以及移動網(wǎng)絡(luò)傳輸速率的都大幅提升。智能手機終端利用移動網(wǎng)絡(luò)進行視頻傳輸成為倍受人們青睞的研究對象。本文設(shè)計并實現(xiàn)了一種實用性較高的無線視頻傳輸系統(tǒng)。 本文首先介紹了這一課題的相關(guān)背景以及研究現(xiàn)狀,介于智能手機市場的主流,采用Android智能手機作為視頻數(shù)據(jù)的采集端,并闡述了最新版本的Android系統(tǒng)框架以及功能特點。此外,本文還對當(dāng)前視頻的編解碼技術(shù)進行了研究,選擇了H.264視頻壓縮編碼方式,同時深入剖析了H.264技術(shù)細(xì)節(jié)。本文用C#語言編寫的一個簡單平臺程序作為播放端,因此也對C#語言和. NET Framework平臺進行了介紹。 本文在具體的設(shè)計實現(xiàn)過程中,采用Android系統(tǒng)的MediaRecorder類實現(xiàn)實時視頻的采集,并利用LocalSocket實現(xiàn)數(shù)據(jù)流的獲取；直接在Android采集端通過分析提取SPS和PPS的信息,獲得原始的H.264實時視頻流；按照RTP/UDP協(xié)議對視頻流進行打包發(fā)送；在上位機終端平臺上,通過移植VLC播放器,并進行SDP會話的方式實現(xiàn)對視頻的實時播放,完成一套基于android的H.264視頻無線傳輸系統(tǒng)的實現(xiàn)。 最后經(jīng)過實際的測試,該系統(tǒng)比較穩(wěn)定,方便使用。同時,由于成本低廉,該系統(tǒng)可以廣泛應(yīng)用,能滿足多種不同的需求。
[Abstract]:With the widespread use of smartphones in people's lives, some dreams that people didn't think of in the past came true. The development of science and technology is undoubtedly an important driving force for Chinese Dream, and the smartphone undoubtedly plays an important role in the development of science and technology. In the past few short years, the information processing ability of the smartphone and the speed of the mobile network have been greatly improved. Smart phone terminal using mobile network for video transmission has become a popular research object. A practical wireless video transmission system is designed and implemented in this paper. Firstly, this paper introduces the background and research status of this topic. In the mainstream of the smartphone market, Android smart phone is used as the video data acquisition terminal, and the latest version of the Android system framework and function characteristics are described. In addition, this paper also studies the current video coding and decoding technology, chooses the H.264 video compression coding method, and deeply analyzes the H.264 technology details. This paper uses C # language to write a simple platform program as the playback end, so also on the C # language and. The NET Framework platform is introduced. In the process of design and implementation, the MediaRecorder class of Android system is used to realize the real-time video capture, and the data stream is acquired by using LocalSocket, and the original H. 264 real-time video stream is obtained by analyzing and extracting the information of SPS and PPS at the Android collecting end. The video stream is packaged and sent according to RTP/UDP protocol, and the real-time video playback is realized by transplanting VLC player and SDP session on the host computer terminal platform, and a wireless transmission system of H.264 video based on android is completed. Finally, after the actual test, the system is stable and easy to use. At the same time, because of the low cost, the system can be widely used to meet a variety of needs.
