  I think it also adds AVIF support?
  - banana_giraffe 4y ago
    Yes, it does: https://github.com/FFmpeg/FFmpeg/commit/84241e63cf2f3cc8f7d8a19e86b99f5af95d2a64 https://github.com/FFmpeg/FFmpeg/commit/84241e63cf2f3cc8f7d8...

  Audio channel layout API finally got a long needed rework https://github.com/FFmpeg/FFmpeg/commit/086a8048061bf9fb4c63943f6962db48175f655c https://github.com/FFmpeg/FFmpeg/commit/086a8048061bf9fb4c63...

  Could someone explain what ipfs protocol support means? What can ffmpeg do with ipfs?
  - hackernudes 4y ago
    Looks like it supports getting data from ipfs:// and ipns:// URIs by using an ipfs gateway, which is basically an http-to-ipfs server. - https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/ipfsgateway.c https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/ipf... - https://github.com/FFmpeg/FFmpeg/commit/f889837e00d3b2388a24c0a9d075ad62f47da825 https://github.com/FFmpeg/FFmpeg/commit/f889837e00d3b2388a24...

    > InterPlanetary File System (IPFS) protocol support. One can access files stored on the IPFS network through so-called gateways. These are http(s) endpoints. This protocol wraps the IPFS native protocols (ipfs:// and ipns://) to be sent to such a gateway. Users can (and should) host their own node which means this protocol will use one’s local gateway to access files on the IPFS network. If a user doesn’t have a node of their own then the public gateway https://dweb.link https://dweb.link is used by default. https://ffmpeg.org/ffmpeg-protocols.html#ipfs https://ffmpeg.org/ffmpeg-protocols.html#ipfs

      And for the avoidance of doubt, yes, ffmpeg is used on multiple planets, not many things are, and many frameworks-du-jour at launch are obsolete by the time the probe actually lands on Mars, let alone end of mission.

FFmpeg is one of those tools that we desperately need a new alternative to. After almost 20 years of Linux I couldn't type a correct FFmpeg command with a gun to my head.

  Gstreamer. It has a learning curve but the documentation is excellent.

  I wrote a simple-sounding script to record pulseaudio null sink on one device and send it to another. Tried a bunch of different ways: parec | opusenc | nc parec | ffmpeg | nc Then discovered that ffmpeg can record directly from pulseaudio and serve it over rtsp. But after a few days of experimenting I realised I could still fuck up the command and be left scratching my head not understanding why it didn't work. Positional arguments in multiple places that affect different things depending on what precedes them. Trying to figure out which part of the command line affects input, cloned streams, output(s) etc. Ffmpeg is a great tool, but seriously hard to use. I ended up not only dropping it for recording and sending over the network, I threw it out completely and ended up with: parec | flac | mbuffer ... Which provides the best quality, consistency and latency. But the best part is that the actual command line isn't much more complex than the pseudo code above.

  ffmpeg is one of those tools which is great and just works, time and time again. You don't know how to use a massively flexible tool that's fine, use something that wraps it, or employ someone who does know how to use it.

  Use handbrake: https://handbrake.fr/ https://handbrake.fr/ It uses ffmpeg under the hood.
- m-p-3 4y ago
  It's an extremely complex mash of codecs, and I'm not sure you could make it simpler while keeping all its capabilities. I personally just make scripts with the required transcoding parameters, and I just look at the documentation again when I need to create a new one.
