Ffmpeg-loop

Instantiate ffmpeg in looping mode.

Purpose

Uses fluent-ffmpeg to instantiate an ffmpeg proc in looping mode

Usage

const expect = require('expect.js');
const opts = { height: 100, width: 100, fps: 30 };
const command = ffmpegLoop('path/to/file', opts);
expect(command).to.be.ok();
expect(command.pipe).to.be.ok();
command.pipe(fs.createReadableStream(/*..*/));
/*..*/
command.kill();

API

module.exports(filename) ⇒ ⏏

Creates an ffmpeg command to loop a video. Note: All crop dimensions are for the original video size (not the output size).

Kind: Exported function Returns: A fluent ffmpeg process - has pipe() method.

| Param | Type | Description | | --- | --- | --- | | filename | string | path to video | | opts.cropHeight | integer | crop height | | opts.cropWidth | integer | crop width (width and height are required). | | opts.cropX | integer | crop x (x and y are optional. If not set, the default is the center position of the video). | | opts.cropY | integer | crop y | | opts.fps | integer | | | opts.height | integer | output height | | opts.loop | boolean | whether to loop the source clip (defaults to true) | | opts.start | float | seek to this time before starting. Must be less | | opts.inputDuration | float | if set we can use this to make sure we don't attempt to start after the end of the input file (ie. we can loop or repeat the last frame correctly rather than seg faulting). | | opts.width | integer | output width than video length. |

Note: To regenerate this section from the jsdoc run npm run docs and paste the output above.
