will (or does) the pi 4 have hardware accelerated h265 encoding ? I know it has h264 options like MMAL or OpenMAX (for ffmpeg), just wondering if anything is in the works, or if its possible(or useful in theory).

Not encoding, just decoding (which is all they mention decoding on the specs)

As one of the RPi engineers / moderators mentioned in a post on the official RPi forums here when asked the same question:

Not on the Pi4, it would require changing the SOC (or the SoC being

redesigned to have an encoder).

He then clarifies:

In fact H265 encode in HW is VERY difficult.

So seems safe to say that it won't be something they can retrospectively add through firmware updates.

  • He also says 'It can do it, just not in real time as that needs HW support.'. Does this mean that it can do HEVC encoding but will just take a long time? Commented Mar 4, 2022 at 11:10
  • This question is about HW support - the part "as that needs HW support" strongly implies that it doesn't have HW support :-) If you're purely interested in whether it's possible at all then presumably yes it is possible extremely slowly in software but that's outside the focus of this question
