This article guides developers on implementing end-to-end direct uploads using Mux Video API, focusing on verifying the direct upload with webhooks in a local development environment. The process involves setting up an endpoint for webhooks and testing it locally by creating a tunnel with Cloudflare Tunnels. It also explains the differences between webhooks and polling and how to set up Mux webhooks. Finally, it demonstrates how to verify video uploads via webhooks by observing browser console logs or terminal window where the server is running.

The text discusses various options available for building a real-time video application, highlighting the complexity involved in developing such an infrastructure from scratch. It mentions the possibility of using open-source projects like Livekit, Jitsi, or Mediasoup to reduce development time but emphasizes that deploying and scaling these solutions can still be challenging. The text then introduces real-time video APIs provided by companies like Twilio and Daily.co as a quicker and more cost-effective way to build such applications without having to worry about the underlying infrastructure. It concludes with an example of how using an API helped in building a successful prototype that secured significant funding for the project.

Using the Mux Video API, the process of implementing an end-to-end direct video upload via an upload button involves setting up both a client and a server, where the server manages confidential environment variables and the client provides a file picker interface. Familiarity with Express API setup, Node, and React event handlers is beneficial. The procedure includes setting up a starter project, creating REST API endpoints, and writing logic for a React upload button to handle video uploads. Upon selecting a video file, a POST request is made to the server endpoint, generating an authenticated URL via Mux. The process uses Upchunk to manage uploading in chunks and handle interruptions. Verification of successful uploads can be done through polling API requests or checking the Mux Dashboard. This approach emphasizes securing Mux API keys and avoiding their exposure in source control, while efficiently managing uploads using the Mux Dashboard and Upchunk.

Mux has introduced a changelog to document changes made to its products from December 1, 2021 onwards. The changelog aims to make product changes transparent and easily accessible for users. Key features of the changelog include discoverability through search and filter options, easy readability with minimal jargon, a streamlined internal process for submitting items, availability as an RSS feed, and trackable analytics. Mux's changelog is hosted in its Docs site to improve accessibility and discoverability. The company encourages feedback on the changelog at [email protected] to continually improve the developer experience.

Mux is offering startups at least $500 in Video credits to access its platform for free. The initiative includes specific credit packages through leading incubators and venture firms such as Y Combinator, Andreessen Horowitz, Pioneer Square Labs, Sweat Equity Ventures, Techstars, and AWS Activate. Mux aims to help startups build video into their products by handling encoding, storage, delivery, and scaling while they focus on other aspects of their business. The $500 in credits can cover significant usage for a startup, depending on the application. Startups can apply at mux.com/startups or find Mux through various platforms such as AWS Activate Console, Andreessen Horowitz Marketplace, and Retool for Startups page.
