Adds support for hardware-accelerated video encoding
To enable hardware-accelerated video encoding add a new config option:
"vaapiDevice": "/dev/dri/renderD128" (Intel CPU example).
This would pass a new set of options to ffmpeg:
-hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128
and it would replace
-c:v libx264 -vf scale=1280:720 -threads 0 -tune zerolatency
with
-c:v h264_vaapi -vf format=nv12|vaapi,hwupload,scale_vaapi=w=720:h=480 -threads 1
Verified to work on Synology NAS DS718+ within Docker environment. More details https://timothybasanov.com/2018/12/08/hardware-accelerated-h264-encoding-synology-nas.html Gotchas: One needs to correctly pass devs into docker and give access to a Homebridge's user.
Additional changes:
- Support for audio encoding
- Better logging integration with Homebridge
- Logs from ffmpeg in Homebridge's logs
I intentionally did not update README, this is a beta feature and I want advanced users to try it first. Not sure how testing is done for this GitHub repo. Hope you can guide me.
I’m interested in this. I wish we didn’t have to know in advance what device provides DRM for vaapi. I don’t know much about probing for hardware acceleration capabilities. Is there a way to have ffmpeg do the right thing on any system, or are we going to be dependent on configuration, or what?
Nice! I just about to buy a DS718+. A factor for that model was the possiblity of using hardware acceleration for homebridge-camera-ffmpeg feeds (something that more expensive Atom models lack). So I wondering if a simular change in that project should be made too. I might take a look once I have my device.
Would be nice to see this merged. I'd also suggest being able to define scale_vaapi.
How about committing to the original repo instead of this forked one? So hardware encoding can be used on a Synology for any camera.
Hi everybody, any updates about this useful functionality? Any idea when Homebridge will support the hardware encoding for the cameras? Thank you!
Hey, I've originally created this PR. I would not be able to update this PR anymore. It would be really nice if somebody would take initiative and merge it either here or upstream. I'm grateful in advance.
