you can try Vulkan encoding
new features are:

• Native decoders: APV, ProRes RAW, RealVideo 6.0, Sanyo LD-ADPCM, G.728
  
• VVC decoder improvements: IBC, ACT, Palette Mode
  
• Vulkan compute-based codecs: FFv1 (encode and decode), ProRes RAW (decode only)
  
• Hardware accelerated decoding: Vulkan VP9, VAAPI VVC, OpenHarmony H264/5
  
• Hardware accelerated encoding: Vulkan AV1, OpenHarmony H264/5
  
• Formats: MCC, G.728, Whip, APV
  
• Filters: colordetect, pad_cuda, scale_d3d11, Whisper, and others
  

Is there a problem or a question somewhere in your post I'm missing?
this should be in https://forum.selur.net/thread-3921.html.
Hybrid will use a fmpeg 8.x build when mediaInfo builds them.
Did you test the vulkan stuff?
Is there a decent and reliable documentation?

AMD GPU encoder using Vulkan is faster than other encoders.

How do you use that encoder? Don't see any info, or mention of an encoder, on the linked page,...

? that shows how to compile it,... if you figure out if this is really what you think and how to use it, let me know

It's faster to convert 4K AV1 video by AMD GPU accelerate, as for me, not every one has NVIDIA GPU

If you have an AMD card have you compared it to https://github.com/rigaya/VCEEnc?
