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.
