Error: Input format lavfi is not available #1282
Description
Version information
- fluent-ffmpeg version: 2.1.3
- ffmpeg version: 7.0.1
- OS: Windows
Code to reproduce
import { default as ffmpeg, default as ffprobe } from "fluent-ffmpeg";
const command = ffmpeg();
command.input("anullsrc=channel_layout=mono:sample_rate=44100");
command.inputFormat("lavfi");
command.addOption("-t", "20");
command.output("test.mp4")
command.run();(note: if the problem only happens with some inputs, include a link to such an input file)
Expected results
Observed results
Error: Input format lavfi is not available
Temporary workaround
// TypeScript
const bypass = (command: ffmpeg.FfmpegCommand) => {
const bk = command.availableFormats;
command.availableFormats = (cb: (err: any, data: any) => void) => {
bk.bind(command)((err, data) => {
const lavfi = {
canDemux: true,
canMux: true,
description: "Lavfi",
};
cb(err, { ...data, lavfi });
});
};
}Checklist
- I have read the FAQ
- I tried the same with command line ffmpeg and it works correctly (hint: if the problem also happens this way, this is an ffmpeg problem and you're not reporting it to the right place)
- I have included full stderr/stdout output from ffmpeg
