To make myself clean How can I transform ffmpeg parameters, in ffmpeg format, to libavformat required by Kdenlive? Can I transform any ffmpeg parameter to libavcodec parameter, like flags?
ffmpeg format: -format dvd -vcodec mpeg2video example: libavcodec (Kdenlive export) format example: format=dvd vcodec=mpeg2video But how to set flags?
