FFmpeg Issues

Ffmpeg is a powerful tool for video editing. Revideo uses FFmpeg for multiple tasks, such as concatenating frames into a video, and audio manipulation among other things.

Revideo uses FFmpeg v6. To make installation easier, we ship a small version of FFmpeg with Revideo. It is automatically downloaded into the node_modules folder. This means that you do not need to install FFmpeg globally on your machine.

Below, we list some common issues with ffmpeg and how to fix them.

SIGSEGV (Segmentation Fault) when running Ffmpeg.​

If you're on Linux, the ffmpeg version used in Revideo might cause a segmentation fault if you use remote urls for media files instead of local files.

You can normally fix this issue by installing nscd:

sudo apt-get install nscd

Using a custom ffmpeg path​

If you want to use a custom version of FFmpeg, you can either set the environment variable FFMPEG_PATH to the path of your FFmpeg binary, or you can set the path to ffmpeg in the render function. Here is an example:

import {renderVideo} from '@revideo/renderer';

// ...

await renderVideo('./src/project.ts', undefined, undefined, {
  ffmpeg: {
    // Points to the global ffmpeg installation,
    ffmpegPath: 'ffmpeg',
  },
});

See the renderVideo API documentation for more information.
