If you need lower load on 4K cameras see: viewtopic.php?f=9&t=27537

Wait what does the hardware acceleration option do then?

I thought that was for GPUs to offset some of the workload

From the reports on the forum, performance of graphics cards is mixed atm. It's new & WIP. Advanced users only.

First upgrade the CPU / motherboard.

So the performance gains from using the hardware acceleration option are not significant, but there are performance gains from using that option right?
I currently have a GPU in that pc and it seems like a waste to have it doing nothing at all. Even if the gains aren't great I'd still like to do it. I just have this problem whenever I try. The logs will say something along the lines of hardware acceleration device not found...

Adding to the end of the source url ":1" fixed audio for me with Tapo (TP-Link) cameras (C120 model) on a Raspberry Pi 5.
User, Pedulla, suggested running this command "ffmpeg -i rtsp://user:password@camIP:554/Streaming/Channels/101 -c:v copy -c:a aac foo.mp4" in terminal to get more details on the url. Mine had suggested 0:0, 0:1
The default stream for my cam ends with "stream1" I just added ":1" to the end. You will need to run the command to get the details for your cameras.
