Show HN: I made a Bluesky video downloader • Hacker News Board

Am I missing something, or are you just concatenating the MPEG-TS segments and slapping an .mp4 file extension on the end? This is not an MP4 file, and won't play in anything that expects .mp4 files to be MP4 files. (It'll still work in a surprising number of places because most players ignore the file extension and sniff the content anyway)

To make this work properly, you need to mux it into an mp4 container. e.g.

    ffmpeg -i video.ts -c copy video.mp4

(there are, hopefully, libraries for doing this that don't involve bundling the whole of ffmpeg)

What is bluesky?

appears to be a twitter clone. On the front page most posts I see are either pictures of manga art or cats.

On firefox you can click the lock icon in the address bar -> connection secure -> more information -> media tab -> sort by 'Type' to find 'Video' -> rightclick that entry and click 'Copy' -> paste in address bar of new tab -> rightclick video -> 'Save video As' This works on most websites that serve you videos.

This does not work for sites that serve videos in a segmented format, such as bluesky

I strongly dislike this new trend of "SEO" spam titles for show HN posts. Show some respect to the community and quit using us as a link-building platform!

What's with the title? Doesn't "Show HN: I made a Bluesky video downloader" provide just as much context as the current version in half the words?

That aside congrats on releasing and thanks for making it a free tool, also impressive turnaround time.

What is bluesky?

I had to ask ChatGPT the same thing.

"Bluesky is a decentralized social network platform that was originally incubated by Twitter and later spun out as an independent company. Its main goal is to create a more open and flexible social media ecosystem by using a decentralized protocol, called the Authenticated Transfer Protocol (AT Protocol). This protocol is designed to allow users more control over their data and enable interoperability across different social media apps that implement the protocol."

I'm sure this is a feature of the browser... Just right click the video and "save as" and it'll give you a .mp4 file right? Or just Ctrl+C to copy the video onto the clipboard. Oh wait, we let commercial interests take that functionality from us...

I don't think you ever could "copy the video onto the clipboard" in anything.

That said, I do wonder why you aren't able to just save as. Is it a "commercial interest" or is there an optimization going on?
