Thanks everyone for taking time to respond my question.
Looks like Haiku developers are investing all resources in Vulkan:

Thanks steampunklolcat and cosmogatokat for those links, that info open my eyes.
I see VA-API and VDPAU are going to be obsolete in the near future.
Now Vulkan support DECODING videos, not just 3d, Khronos called Vulkan Video Api:
Also FFmpeg supports Vulkan video decoding:
At the beginning of this post, I was mentioning that I have 2 old video cards (no Vulkan support) also I have an old mac tower (this macpro was updated from 4.1 to 5.1)
From this link:
*This model has four full-length PCI Express (PCIe) 2.0 expansion slots, two x16 slots and two x4 slots. In the default configuration, one PCIe 2.0 x16 slot is occupied by the graphics card. Apple also reports that “all slots provide mechanical support for 16-lane cards” and there is a “300W combined maximum for all PCI Express slots.”
I was checking in newegg.com for Radeon RX 6400 (this is a PCI Express 4.0 Video Card), I’m not sure if this card is going to work in a PCI express port 2.0???

Radeon RX 6400 is cheap and support Vulkan 1.3:
If the card works with the old mac tower, I would like to buy one, and try to help Haiku.
What is your opinion about this video card?
I’m asking because Haiku community has more skills and experience than myself.
