Nvll_osd_put_text only support MODE_CPU?

• Hardware Platform: Jetson
• DeepStream Version: 5.1
• JetPack Version: 4.5.1
• TensorRT Version: 8
• Issue Type: questions

Hi,
From the API document below:
https://docs.nvidia.com/metropolis/deepstream/sdk-api/group__ee__nvosd__api__group.html#ga82e2fd6f18cd628b2e53de8be4d39800

Currently only the NvOSD_Mode value MODE_CPU is supported. Specifying other modes has no effect.

it mentioned only MODE_CPU is supported.
In code of gst-nvdsosd plugin, I saw that it is still also supported GPU & HW modes.
Can anyone confirm in deepstream 5.1, Jetpack 4.5.1, the nvll_osd_put_text() function supported mode HW for Jetson or not?

PS: another question is does nvll_osd_put_text support other image formats than RGBA?

Thank you.

Specifying other modes has no effect in this API. You can set other mode, but it has no effect.

Thank you. But then it means that the OSD is done by CPU on Jetson? Or it is actually done by HW?

It just affect the text , not the whole OSD picture.
