Abstract

The objective of this work is to perform real-time full HD video encoding by using the x264 library. This library implements in software a high performance H.264/AVC encoder whose set of configuration parameters contains a large number of options. Thus, a methodology is proposed in order to select a relevant subset of parameters which allow real-time encoding and maximum video quality for a given computational complexity. Based on the results of this methodology, it was selected a set of settings that allow real-time encoding and maximum quality for a given complexity. The results show the optimized system has a significant performance improvement in relation to the predefined x264 profiles. In terms of PSNR, the improvement in performance is superior to 1 dB.
