  • The FFmpeg Tutorial
    1 project | news.ycombinator.com | 30 Oct 2022
    The FFmpeg libraries are possibly the worst thing I have ever worked with in my life. I have never been more afraid to use a library than this one. This tutorial is very outdated, eg. `AVPicture`, which is used throughout, is completely deprecated and removed from the library, so you will simply encounter linker errors trying to follow this tutorial.

    FFmpeg libraries randomly break themselves, so if you find an answer from a few years ago, chances are it's useless. Want to free an AVPacket? `av_free_packet` is deprecated,. You can use `av_packet_unref` (but there's _also_ a function named `av_packet_free` that doesn't do quite the same thing).

    Most questions on Stack Overflow or related platforms have no replies, the library has literally zero documentation, it has very little error handling, which means if you're a bad C developer like me you are required to recompile FFmpeg with debugging information unstripped so you can trace segfaults in gdb.

    https://github.com/leandromoreira/ffmpeg-libav-tutorial/ is a better and more up-to-date tutorial than this one.

    I found this . I think you need an older version of ffmpeg to use the program, try to write it under the AUR to see if the mantainer is still active and knows the problem.

    Much of it I learned from An ffmpeg and SDL Tutorial (outdated, but the core idea persists), and from ffmpeg-libav-tutorial.

    Btw, if you want to encode anything higher than 1080p60 using the Videocore VI, you'll need to use an external library like ffmpeg. There is a good tutorial for ffmpeg too - https://github.com/leandromoreira/ffmpeg-libav-tutorial . This should teach you how to encode the raw video stream you get from the camera into a codec of your choice.

  • Show HN: I Added a Feature to WhatsApp-Web, Animated GIFs Uploads (Chrome Ext.)
    3 projects | news.ycombinator.com | 23 Aug 2024
    Hi HN! I'm Ivan, the creator of this extension and with it you can now right-click any gif on Google Chrome (desktop) to share it with any of your contacts on WhatsApp Web, you can also use it to upload animated GIFs from your computer, you can even drag-and-drop MP4 files to it and they will be treated as gifs (e.g. they will loop, muted of course). Another nice feature its that it lets you share non-gif images with the same context menu option (e.g. AKA right-click menu)

    To create it I had to do a bit of reverse-engineering of the existing JavaScript found at https://web.whatsapp.com/, which is actually a minified React app, I found out that it uses WebSockets to communicate with the backend but thankfully to create this extension I was able to avoid fiddling with those messages. Under the hood it uses the amazing library ffmpeg.wasm (the JS port of ffmpeg): https://github.com/ffmpegwasm/ffmpeg.wasm I also made use of TypeScript, React and Vite to create this extension, using this boilerplate as starting point: https://github.com/Jonghakseo/chrome-extension-boilerplate-r...

    Feel free to ask any questions or any feedback you may have about it.

  • FFmpeg 7.0 Released

    There's a low-hanging fruit that I think would make ffmpeg more helpful for regular people.

    There's a million terrible websites that offer file conversion services. They're ad-ridden, with god-knows-what privacy/security postures. There's little reason for users to need to upload their files to a third-party when they can do it locally. But getting them to download fiddly technical software is tough - and they're right to mistrust it.

    So, there's a WASM version of ffmpeg, already working and hosted at Netlify [1]. It downloads the WASM bundle to your browser and you can run conversions/transformations as you wish, in your browser. Sandboxed and pretty performant too!

    If this tool a) was updated regularly b) had a nicer, non-CLI UI for everyday users and c) was available at an easily-Googlable domain name - it would solve all the problems I mentioned above.

  • FFmpeg-online: ffpmeg running on the browser

    As their github page says, based on https://ffmpegwasm.netlify.app ...

    I'm guessing no one did GPU-optimizations? I saw a web app (not an ffmpeg transpilation) that went clever and used WebGL so it can access the GPU and use its parallel processing capabilities...

  • Locoly (locoly.app): an in-browser video editor running all computations locally

    ffmpeg.wasm: The engine making all these happen. However, I’m a bit concerned about its current situation. The repo has not been updated for more than six months now, and that’s not a healthy sign for an open-source project. Clearly I was reading the commits wrong. The author mentioned “speed up x264 with SIMD intrinsics” in their roadmap (https://github.com/ffmpegwasm/ffmpeg.wasm/discussions/415), which, if landed, could make such on-device video editors much more competitive.

    1 project | /r/webdev | 16 Jun 2023
    You could try using something like ffmpeg wasm which is a way of using ffmpeg client side in browser. Unfortunately WebAssembly only supports files less than 2 gigabytes, which is a problem for videos. And I don't know if ffmpeg wasm contains ffprobe, so you might have to find another project or try to compile ffprobe to wasm yourself. This stuff is out of my wheelhouse so I can't offer much help.
