Intel or AMD for ffmpeg? (discuss.tchncs.de)
submitted 9 months ago by cmgvd3lw@discuss.tchncs.de to c/linux@lemmy.ml

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.

  • Hardware (GPU) encoders are worst than software encoders.
  • GPU Acceleration is good for faster encoding and free CPU to do other things. But you get bigger files at similar quality.
  • Maybe is useful for live streaming or if you really really need CPU do other things.

Yes this is indeed what I said. but well calling gpu encoders "worse" isnt really fair, it's all trade offs, they for sure have worse efficiency as we both said, but their speed is significantly faster usually. I would say that doesn't make the encoder "worse" just different.

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.
