From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Intel or AMD for ffmpeg? (discuss.tchncs.de)

With no graphics card specific compilation to the ffmpeg, which among intel or AMD is better for executing

ffmpeg -i input -c:v libx265 -crf 26 -preset fast -c:a aac -b:a 128k output.mp4

Would tight integration between amd cpu + gpu help in this case?

Fyi. Currently i am using intel with cpu only mode for this and its pretty slow.

AMD APUs have Video Coding Engine / Unified Video Decoder, while Intel CPUs have QuickSync. FFMPEG's hardware page says that AMD support is incomplete.

You may want to ask over in [email protected] . This topic often came up back on Reddit, and the general vibe I got was that most people prefer QuickSync. Intel may not be great in a lot of areas, but they are a beast in video encoding/decoding. That being said, I use a Ryzen APU and it's perfectly fine. There are way more important things to look at when choosing a CPU.

If your performance is slow, I would check your CPU is listed on the chart I linked above. Not all CPUs support all codecs.

Edit: If your CPU doesn't support the codec, it will still work, it just won't be accelerated.

quicksync really doesn't have good quality:compression buying a used nvidia gpu and using that would be far better. but really, any moderatly up to date cpu should get good x265 or svtav1 perf
