Aerial Video Encoding Optimization Based On x264 ()
ABSTRACT
x264 video codec uses lots of new video encoding technology based on H.264/AVC video encoding standard which enhances compression efficiency. However this results in so heavy computation that the x264 codec is not fit for real-time encoding application of high resolution video. This paper analyses the character of aerial video and then opti-mizes the inter-frame mode decision and motion estimation in x264 codec according to its character by reducing a lot of unnecessary computation. In the result, about 19% computation and encoding time is reduced with total bits and PSNR decreasing lightly.
