Hardware transcoding 101

(this topic is intended to be related to hardware transcoding - not software transcoding, thanks)

Ok, we know the RPi 4 can only transcode one stream at a time, but if you have a different platform is there any way to figure out how many simultaneous hardware transcodes may be possible at one time?

  • Is it based on cores the CPU has or is it related to the GPU somehow or both?
  • Are there any rules of thumb?
  • If using an Intel processor is there a link to a reference chart anywhere?
  • Does it vary by OS? Win10? MacOS? Linux?

Actually, just found this which is helpful info.
