The open source software 'Opencast' offers a complete video processing system that includes all necessary components for recording, processing and distribution of video files like lecture recordings. In the course of a workflow, the files are encoded according to the requirements using a modern video compression standard. Typically, the algorithms for this are run on the processor of a machine, but various hardware accelerators exist that promise more efficient processing. This work deals with the integration of an acceleration card based on FPGA technology into an Opencast workflow. For this purpose, appropriate adaptations to an existing workflow as well as suitable encoding profiles are designed and implemented. An evaluation is then carried out that compares the FPGA acceleration card with a software-only implementation. Meaningful criteria and metrics are considered, presented and then applied to test files.
