Does Verdin support HD VPU H265 encode operation?

[rifo]

Hello,

Does Verdin imx8m plus quad 2GB WB IT support HD VPU H265 encode operation?

If I understood correctly, Alvero.tx has stated that VPU support is added in below thread

Can the iMX8plus support a 4k15p dual camera?

Hi @p-uchi , you should also consider the VPU encoding capabilities, which seems to ve be limited to 1080p60 in the i.MX8MP. Otherwise you will have to use SW accelaration which could be very very slow / 100% CPU usage. [image] I see some users commenting in NXP forum about encoding 4K with i.MX8MP and NXP discouraging this because of limitations of the SW control: We recently added VPU support in Torizon, so let us know if you need more help on this. A single 4k camera seems to be too …

Does the latest BSP support HD VPU H265 encode operation out of the box?

Side note

I got the Gstremaer pipeline from the WIP that R&D is currently doing for Torizon on this topic: torizon-samples/vpu/generic/vpuGeneric/vputests.sh at bf2534dc3826d53d3b38f56afc223beb4f475d82 · embdur/torizon-samples · GitHub. Thanks @leon.tx for the tip
