Feel free to comment any suggestions: Proposal Video filtering with OpenCL Currently, FFmpeg has good support for offloading decoding and encoding from the CPU, but not such good support for doing anything else with that video without using the CPU. There is interop support for mapping between APIs so that generic methods like OpenCL which can be run on any GPU can be used together with specific video APIs for decoding and encoding, but currently there are only a few operations which can actually use this so many use-cases require expensive additional steps to download frames from the GPU and then upload them again later after performing some processing on the CPU. Therefore, we would like to add more OpenCL filter support to libavfilter so that more operations can be offloaded. This includes implementing a scaler, supporting a choice of scaling algorithms, a deinterlacer and color conversion. Timeline I have a report due for uni in June. This should only take a day or two. Other than that, I have no commitments. All tasks below include writing documentation. Week 1-2: Implement OpenCL deinterlacer based on yadif Week 3-6: Implement OpenCL YUV-to-YUV color conversion based on vf_colorspace Week 7-9: Implement OpenCL rgb colorspace conversion Week 10-14: Implement scaling algorithms with OpenCL including bilinear, bicubic, and averaging area _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
