💎 FLV to MP4 with Ruby

Convert FLV videos to MP4 format online for compatibility, delivery, and playback across devices and platforms.

RubyREST APIFLV → MP4

Use this guide to convert FLV to MP4 with Ruby, then adapt the example to your own app, backend, or processing flow.

Overview

What this guide covers

Conversion path

Use Converterer to accept or prepare a FLV file, trigger a FLV to MP4 job, and return the output to your app or workflow.

Ruby example

Start with the example on this page, then adapt auth, file handling, polling, and result delivery to your environment.

Production usage

This is best suited to backend jobs, async processing, content pipelines, and repeatable conversion flows rather than one-off browser scripting.

req.set_form(
  [
    ['input', File.open('input.flv')],
    ['output_format', 'mp4']
  ],
  'multipart/form-data'
)

res = Net::HTTP.start(uri.host, uri.port, use_ssl: true) do |http|
  http.request(req)
