A colleague raised a question — how does the Pi 4 actually encode? A question asked — an answer must be given. 🙂 I borrowed one from him for analysis for a while . Frankly speaking, the processor is quite slow. But that’s not surprise, since enthusiasts don’t require much computing power for their projects […]

In case of libaom-av1 it’s “-cpu-used” parameter value stated. Hardware codecs Hardware H.264 HEVC AV1 NVIDIA RTX A4000 Low Latency p1 Low Latency p1 […]
Read MoreSo, I finally get to a Rockchip. I must say this hardware is highly ambiguous, with plenty of issues but no fewer merits. I bought it for video encoding, surely. Unexpectedly, it has turned into a permanent member of my home lab. If you compare the overall CPU performance, for example, with the BCM2712 (Raspberry […]
Read MoreLet’s examine how Intel encodes on modern graphics cards. My previous experience was entirely unimpressive, starting from building the source code and preparing for encoding in general. An embarrassingly large amount of time was spent on what seemed like a simple task. We even had to involve system programmers just to even get MFX working. […]
