Up until now ffmpeg seems to have built and nvenc has worked for me without the SDK being installed at compile time - since I and others cross-compile ffmpeg under Unubtu/mingw64 for target Windows 10 x64, installing the nvidia SDK in this scenario is not an option. Can you please clarify whether indeed the Nvidia SDK 11.1 or greater is now actually required to be installed in order to build ffmpeg with nvenc/nvdec enabled ? Thank you. If so, it's probably a deal breaker for cross-compiling ffmpeg ? Thank you. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9370> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
