`js
const extractFrames = require('ffmpeg-extract-frames')
// extract 3 frames at 1s, 2s, and 3.5s respectively
await extractFrames({
input: 'media/1.mp4',
output: './screenshot-%i.jpg',
offsets: [
1000,
2000,
3500
]

Extracts one or more frames from a video file. Returns a Promise for when all frames have been written.
There are several options for specifying which frames to extract, namely timestamps, offsets, fps, and numFrames. The default behavior if you don't specify any of these options is to extract all frames from the input.
#### options
##### input
Type: String
Required
Path or URL to a video file.
##### output
Type: String
Required
Output file pattern.
Note that for timestamps or offsets, the pattern should include a %i or %s (details).
For any other call, you should use the %d format specifier. I know this is confusing, but it's how fluent-ffmpeg works under the hood.
##### offsets
Type: Array
Array of seek offsets to take the screenshot from in milliseconds.
##### timestamps
Type: Array
Same as fluent-ffmpeg's screenshots.timestamps.
##### fps
Type: Number
Frames per second to output.
##### numFrames
Type: Number
Output a specific number of frames. The input video's frames will be skipped such that only this number of frames are output.
##### log
Type: Function
Default:
Optional function to log the underlying ffmpeg command (like console.log).
##### ffmpegPath
Type: String`
Specify a path for the ffmpeg binary.
