Alternatively, Node.js streams may be given to pipe in/out from the stream. The url properties of inputs and outputs options are typically strings, which are then copied verbatimly as ffmpeg spawn arguments. run ( ) = > // internally calls spawnįnSync()= > // internaly calls spawnSync FFmpeg input & output urls Windows users: most probably ffmpeg and ffprobe will not be in your %PATH, so you must set %FFMPEG_PATH and %FFPROBE_PATH. Most features should work when using avconv and avprobe instead of ffmpeg and ffprobe, but they are not officially supported at the moment. If not found, it then will try FFMPEG_PATH then will attempt to call it in the PATH. Similarly, kiss-ffmpeg will use the FFPROBE_PATH environment variable if it is set. You must also have ffprobe installed (it comes with ffmpeg in most distributions). Otherwise, it will attempt to call ffmpeg directly (so it should be in your PATH). If the FFMPEG_PATH environment variable is set, kiss-ffmpeg will use it as the full path to the ffmpeg executable. Kiss-ffmpeg was developed and tested with the latest FFmpeg (v4.2.1) but should work with all recent releases.
