I know C++1z, C++14, C++11, etc., as well as C11., have very good knowledge of various Linux APIs for image and video transformation, such as ImageMagick, FreeImage, ffmpeg, etc., and have also worked with DirectX on Windows. I have experience with converting a Windows-specific app to work on Linux, as well as with multithreading on both high-level and low level (atomics, memory ordering, etc.), so I know how to manage the async task of video conversion.
The project is rather straightforward, as is translating applications from DirectX and Windows to Linux-specific APIs, so I should be able to complete it in around 4-5 days.
