Create an AMF/ directory in the system include path.
To enable support you must obtain the AMF framework header files (version 1.4.9+) from. execute () if _name_ = "_main_" : asyncio. FFmpeg can use the AMD Advanced Media Framework library for accelerated H.264 and HEVC (only windows) encoding on hardware with Video Coding Engine (VCE).

You can see how MobileFFmpeg is used inside an application by running test applications provided. run ( main ()) Recording Synchronous API from ffmpeg import FFmpeg, Progress def main (): ffmpeg = ( FFmpeg (). ffmpeg -i video.mp4 -vf 'fadetin:st0:d3' -c:a copy out.mp4 This will start the video with a black screen and fade in to full view over 3 seconds. For audio, the afade filter can be used to achieve a similar effect. execute () if _name_ = "_main_" : asyncio. Using ffmpeg, you can apply basic fade in and fade out to video using the fade filter.
