[Objective] The paper aims to expand the supporting ability of the CSpace Institutional Repository for audios and videos. [Context] The ever-growing audios and videos resources, require us to expand the Institutional Repository’s supporting ability, which help us retrieve knowledge and increase their academic values more effectively. [Methods] First, we analyzed the needs of users and the developments of Institutional Repository’s audios and videos supporting services at home and abroad. Then, we constructed an extension framework for the supporting functions. Finally, we chose the key technologies and methods to build the experimental platform, and explored its feasibility in CSpace. [Results] The proposed method helped us change audios and videos clips’ formats, analyze video scenes and develop a video player with scene navigation functions. [Conclusions] The transcoding technology for audios and videos works effectively. However, other supporting functions could be further improved. The format conversion technology for audios and videos in CSpace could expand its supporting services.
