Question: what is the state of hardware video decoding on the Raspberry Pi 3 B+ platform ?
I'd like to know if hardware video decoding is available on the RPI3B+ ? Our target usage is low-latency video but we're not sure about compatibility, and would like a formal answer to help us choosing the right platform.
Thank you for your answer
As a start, you might want to check out the posts from smiesche in "Video playback on RPI 4 not working" back in July 2021.
Also emteria had a blog post back on Jan 31, 2022 :

I haven't seen anything about RPi4B HW video acceleration from emteria since then.
The Raspberry Pi 3 B+ does support hardware video decoding. It has a VideoCore IV GPU that can decode H.264 video up to 1080p resolution and 60 frames per second. This means that it can play back high-definition video without putting a strain on the CPU.
Hardware video decoding is important for low-latency video applications. This is because it frees up the CPU to do other tasks, such as processing user input or streaming video to a network. Without hardware decoding, the CPU would have to decode the video itself, which would introduce latency.
The Raspberry Pi 3 B+ is a good choice for low-latency video applications. It has a powerful GPU that can decode H.264 video quickly and efficiently. This makes it ideal for applications such as live streaming, video conferencing, and gaming.
Here are some additional details about hardware video decoding on the Raspberry Pi 3 B+:
I hope this information is helpful. Please let me know if you have any other questions.
Did the above step work?
In case it didn't, the the additional details about hardware part that I mentioned along the solution.
