 '''Description:''' FFmpeg has good support for offloading decoding and encoding from the CPU, but not such good support for doing anything else with video without using the CPU. Therefore it would be beneficial to increase libavfilter's support for OpenCL filters, which would allow to offload more operations to the GPU, making the CPU less busy. The project aimed to add more OpenCL filters to libavfilter.

 '''Results:''' During the GSoC period, the following contributions to the project have been submitted:
 * boxblur_opencl filter. Status: [[http://git.videolan.org/?p=ffmpeg.git;a=commit;h=714da1fd898f83c7bef38fe427af3692917cbcb2|commit]]. This filter applies [[https://en.wikipedia.org/wiki/Box_blur| BoxBlur algorithm]] to the input video.

 '''Future work:''' Seeing the patches that are still in review to the end, implementing additional OpenCL support and optimizing the already existing OpenCL filters.
