raspberry pi 4 h.265 hardware accelerate encode

[jt1988]

I've seen that the raspberry pi 4 will come with hardware accelerated h.264 decode+encode, and h.265 decode.

I was wondering if there are any plans to support h.265 hardware accelerated encoding with the rpi 4 at some point in the future?

Thanks!

Not on the Pi4, it would require changing the SOC (or the SoC being redesigned to have an encoder).

In fact H265 encode in HW is VERY difficult.

Does it still require a license key? YouTube video encoding seems to be slow, and I'm wondering if it's because I'm not actually using the Hardware Decoder?

No licence key needed. We are currently tracking down a bug in Chromium which when fixed should speed things up.

Until the bug is fixed, disabling OpenGL video driver in config.txt makes YT video playing with Chromium much faster

First off, amazing work with the rpi4. I'm blown away by all the improvements from the 3B+. multiple USB3, internal PCIe, True Gigabit Ethernet, the list goes on..

Thank you for the response! Bummer, understood. Even though there's a much better CPU + much more RAM, it seems like doing SW H265 encoding on the 4B is a non-starter.

My use case was to enable H265 storage of video on the pi itself [so my 4b + arducam + SD card could store ~50% more video than with H264].

It can do it, just not in real time as that needs HW support.

I've seen you or one of your fellow colleagues mentioning this bug in another thread. Could you mention the ticket no. so we can track it as well, please?

+1 on this. Please give us a bugtracker link to follow.

I believe it is fixed and can be tested using rpi-update. You will need to turn gpu acceleration on in Chromium.
