The study of video acquisition and compression codec system based on DaVinci
Yakun Liu, Xiaodong Cheng · 2010
This paper achieves the design of a video acquisition and compression codec system, which takes dual-core chips TMS320DM6446 as its core and Linux as its operating system. This is because Linux can be reduced and transplanted. The video capture device driver V4L2 and Codec Engine are introduced in detail, and through H.264 algorithm functions of video compression codec are successfully realized. Relevant experiments show that the codec algorithm has strong performance of anti-errors and the videos are clear and reliable after compression codec. Moreover the mount of the video data is largely reduced.
