Extract one or more specific frames from a video file

Usage

ov_video_frame(
  video_file,
  t,
  n,
  format = "jpg",
  debug = FALSE,
  framerate,
  method = "auto"
)

video_file: string: path to the video file
t: numeric: the times of the frames to extract (in seconds)
n: integer: the frame numbers of the frames to extract. Ignored if t is provided. Frame numbering is 1-based (first frame at t = 0 is frame n = 1)
format: string: "jpg" or "png"
debug: logical: if TRUE, echo the ffmpeg output to the console
framerate: numeric: the framerate of the video. If not supplied, it will be found using [av::av_video_info]
method: string: the method to use, either "ffmpeg", "av", or "auto". "ffmpeg" is faster than "av" but requires that ffmpeg is available on your system path. If method is "auto", "ffmpeg" will be used if available and "av" if not

The paths to the frame image files

video_file <- ov_example_video(1)
img <- ov_video_frame(video_file, t = 5)
img <- ov_video_frame(video_file, n = 150)
