Detailsįfmpeg is a wrapper function around the popular FFmpeg command line multimedia framework. Returns the system call to FFmpeg as a character string. Logical, whether to show FFmpeg output on the R console. Linux users, see details on how glob affects pattern. Only applicable when pattern is vectorized, referring to layering of multiple image sequences.ĭefaults to 1.0 (non-transparent) since mapmate produces transparent-background png sequences by default with subsequent layering in mind. This can be given in the same ways as rate. Integer or character, framerate of output video. Integer, the minimum frame rate for non- gif video output ( mp4, mov, mkv, webm). Set to zero if your image sequence has file names beginning from zero or a higher number if you want to skip frames. Logical, use lossless H.264 encoding if applicable. See details.Ĭharacter, the video codec used. See details.Ĭharacter, encoding presets available in FFmpeg. Otherwise scaling is performed on the output. Defaults to 'source', which is equal to the dimensions of the input files. Defaults to start=1.Ĭharacter, the dimensions of the video output. Integer, frame to start from in input image sequence. Numeric, time delay between frames in output video. Integer or character, intended framerate of input image sequence in Hertz (Hz) or frames per second (fps). See details for acceptable and possible alternative patterns.Ĭharacter, output directory.
