The incredible part is the RPi sucks less than all the other commercial embedded SBCs such that it's had huge industry uptake purely by being the least worst. The state of the embedded industry continues to amaze me.

Do you actually implement all permutations of vpternlogd? The lightweight macro layer in ffmpeg takes care of v prefixes. In FFmpeg, x264 and dav1d there are many different examples of code that couldn't be written in intrinsics or oth

The paper suggests FFmpeg uses intrinsics which is not correct. There have been many SIMD abstraction layers created in the past but none of them will beat the raw speed of handwritten assembly. Try and implement something like vpternlogd i

The AMD Alveo ASIC isn't actually available to buy yet. Their older Alveo FPGA (formerly NGCodec) is available but is not competitive by any metric apart from marketing noise.

Sure, when there's a consistent experience between browsers with decent echo-cancellation amongst other audio processing I'll be happy to move. I don't want to get stuck on lowest common denominator WebRTC, that pales in comp

This isn't the fault of RPi as such. It's the fault of the whole embedded industrial SBC industry whose boards are expensive, long lead time, have awful software and are poorly documented.

It's easier to do an update with a single security fix rather than an update that rolls in a ton of new functionality that ends up breaking your device. Seen this time and time again with OS/dependency update.

Yes, there's substantial value in being able to have a specific bugfix and not have to upgrade an application and a ton of dependencies.

Absolutely spot on here, there's no reason for the obsession HN (and the wider internet) has with upgrades in these kinds of environments. These are not environments where you can tolerate unplanned downtime, this isn't a silly we

The RFC does not mandate that the RTCP timestamp (which you need to handle wraparound if you join a stream halfway through) needs to be the same as the video/audio clock. In practice this clock is generated via the PC clock so it isn&#

Just to be clear this is is a patch and is not necessarily going to be accepted into FFmpeg.

Unfortunately the industry I am in (multimedia) is slowly getting invaded by all the awful embedded development practices, binary blobs, custom forks, hacks galore. It's ruining an area where there was clean code, no blobs. Also Linus&

Embedded development is substantially worse when it comes to out of tree unmaintainable kernel patches, compiler forks, binary blobs around terrible hardware etc etc. Completely incomparable to web, enterprise and mobile (android and co is

Seems to miss the part where it's ok to create terrible software in embedded, with custom forks of everything, binary blobs galore. But it's all fine as it shaves a few cents from the BOM.

I do wonder if anyone actually read the Amazon post before creating their hot takes. The crux of the post is simple and obvious to anyone who's ever actually developed "low-level" (used loosely) video libraries. Microservices
