[Config Support]: Enable HEVC/H.265 on Friagte

[bracan12]

Describe the problem you are having

I am using frigate in Home Assistant installed on a Raspberry PI4B and try to configure a Reolink RLC810A for detecting in 4K(Main Stream). I noticed H.265 works without Hardware Acceleration but with very high CPU usage and very laggy. I added the following flags to hwaccel_args and I get a green screen.

Is there a way to encode H265 with hwaccel_args on PI4?

0.10.1-83481AF

The hardware acceleration flags work with H264 substream but I need to work it with H265 Main Stream

[NickM-27]

The hardware acceleration flag is h264_v4l2m2m so naturally it will only work with h264. Did you try hevc_v4l2m2m ?

[ghost]

Thank you. I tried it with hevc_v4l2m2m but unfortunately it had no effect, still showing a green screen. Debug Camera FPS is also at 0.

[NickM-27]

You can run ffmpeg -decoders inside the frigate container to see what decoders are supported

[ghost]

Yes the command gave me a bunch of codecs but from my research the only suitable codec for my PI4 is actually hevc_v4l2m2m. But I can't explain why it is not working.

[NickM-27]

Maybe try frigate 0.11 RC it has a new ffmpeg build that could work better

I don't believe the Pi has hwaccel for h265

Oh yeah, looks like it is an open issue in the jellyfin repo https://github.com/jellyfin/jellyfin-ffmpeg/issues/129

workaround to use h264-streams from RLC810A:

1. upgrade Fw to last from here
2. change encode resolution for "clear"-stream to 2560*1440
3. enable RMTP under Network-Settings/Port-Settings
4. you can use following h264 RMTP-streams now: clean (2560x1440): rtmp://{IP}/bcs/channel0_main.bcs?channel=0&stream=0&user=admin&password={password} balanced (896x512): rtmp://{IP}/bcs/channel0_ext.bcs?channel=0&stream=2&user=admin&password={password} fluent (640x360): rtmp://{IP}/bcs/channel0_sub.bcs?channel=0&stream=1&user=admin&password={password}

It does... https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-datasheet.pdf

H.265 (HEVC) hardware decode (up to 4Kp60)
H.264 hardware decode (up to 1080p60)

It supports h265 but ffmpeg does not currently support it
