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?

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

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