NvBufSurfTransform interface error：“Failed to configure VIC Target Surface”

[DaneLLL]

Hi,

Hi,when I run gst-dsexample code, it can convert NV12 format to RGBA format successfully, but when I convert NV12 format to BGR format ,the same error printing will still appear.I want to know if this is a hardware or software limitation.Are there
any good ways to convert NV12 format to BGR format by using hardware?

It is limitation in hardware engine. Please refer to a similar topic:
[Gstreamer] nvvidconv, BGR as INPUT - #2 by DaneLLL

The solution is demonstrated in dsexample sample. Need to convert to RGBA through NvBufSurfTransform() and to BGR through cv::cvtColor().
