【摘要】：隨著科技社會的發(fā)展,安防監(jiān)控領(lǐng)域視頻設(shè)備的高清化已成為新的發(fā)展趨勢。采用TI最新推出的達(dá)芬奇單片系統(tǒng)TMS320DM8168,設(shè)計了一套高清視頻監(jiān)控系統(tǒng)。主要介紹了V4L2在該系統(tǒng)中的實現(xiàn),主要包括視頻接口設(shè)計、V4L2采集設(shè)備驅(qū)動開發(fā)和V4L2采集應(yīng)用程序設(shè)計等內(nèi)容。測試結(jié)果表明該系統(tǒng)中實現(xiàn)的V4L2驅(qū)動和應(yīng)用程序能夠為DM8168高清視頻監(jiān)控系統(tǒng)提供高清視頻數(shù)據(jù),具有良好的可靠性和穩(wěn)定性。
[Abstract]:With the development of science and technology, the high-definition video equipment in the field of security surveillance has become a new development trend. A high-definition video surveillance system is designed by using TI's latest da Vinci monolithic system TMS320DM8168. This paper mainly introduces the implementation of V4L2 in this system, including the design of video interface and the development of V4L2 acquisition device driver and the design of V4L2 acquisition application program. The test results show that the V4L2 driver and application program in this system can provide high-definition video data for DM8168 high-definition video surveillance system, and it has good reliability and stability.
