There seems to be some things that are misunderstood here.
also frigate itself does not do encoding. For go2rtc encoding you would just provide a secondary stream ffmpeg directive that transcodes to h264 and adds The logs show something is not implemented |

Regarding the deckcam, I only get that when I set the global ffmpeg hwaccel_args, if I don't have that on, that camera works like a charm, which with it being MJPEG I wouldn't think it would break with the hardware encoder, but I am far from an expert or power user in this realm. As for the others, if I set everything to use go2rtc, I'm having trouble figuring out how to do the hardware decoding and encoding in go2rtc. Granted that means I will then have to decode the stream again in the camera config section, but that's fine in my book as the GPU is a beefy little guy and in the end will have < 6 total cameras on the system. My ultimate goal is to have all the cameras decode in go2rtc then re-encode into a new stream that not only is consistent (h.264), but all my external devices can pull from these streams from go2rtc as the camera source instead of the cameras themselves, taking the load off the cameras. |

Describe the problem you are having
I am attempting to get hardware acceleration setup for both decoding and encoding. The first situation, the decoding, I have 3 different types of cameras, one is an MJPEG, one is a h.264, and one is a h.265 only. Obviously the MJPEG doesn't need decoding, but I would like to use the Quadro M2000 card I have installed to perform the decoding of the two h.264 and h.265 streams.
I have validated the card is working by adding "hwaccel_args: preset-nvidia-h265" to the global ffmpeg directive and I can see the decoder running on the card. What I also see is my MJPEG camera no longer has a stream that can be opened and my h.264 cameras suddenly become very unstable.
So first part of the question is, how do I set the configuration to perform ALL decoding using hwaccel? I tried using an array to the hwaccell_args and Frigate wouldn't start, so not sure what I'm missing. What I mean by an array is the following in the global FFMPEG directive
So not sure how to get that configured, but does also go with the second part of my issue. Obviously there's issues with displaying the h.265 stream in the Birdseye view or in reviewing the recordings, so I thought that setting up the go2rtc function would be perfect to transcode the stream into h.264 in order to view in the Birdseye and the Recordings screens, but I just can't get my head wrapped around it to get it to work. I've tried a whole bunch of iterations to get this to work.
So for a little more context, the h.265 camera is a Reolink Duo 3 PoE, with the combined stream of both cameras, resulting in a native resolution of 7680x2160 and not separation of the cameras into separate streams. I have tried to reduce the resolution down to 4096x1152 but the stream still comes in at h.265. The substream does come through as h.264 but is limited to 1536x432, which is fine for detection but not for recording and getting any meaningful details. So I fall back to needing to transcode the stream into h.264, even if that means that the resolution has to be 4096x1152.
Looking for guidance and advice here. Ultimately, I would like all the cameras to come into Frigate and then use go2rtc to rebroadcast/transcode to any other sources that need the camera feeds, such as Scrypted, so this is part of a larger goal.
