NvVideoConverter problem

I have problem with NvVideoConverter class (MM API). When he recieve decoded frame from NvVideoDecoder error occures

libv4l2_nvvidconv (0):(1688) (ERROR) : NvDdkVicConfigure Failed
libv4l2_nvvidconv (0):(1710) (ERROR) : NVVIDCONV ERROR 2
NvMapMemHandleCreate: error 9

and app is craching. It’s happening when decoder work with interlaced frames. I configure converter by MM API examples (video_decode).

SDK Ver. 32.1

Please try NvBufferTransform() defined in nvbuf_utils.h

Need to repalce NvVideoConverter to NvBuffer Transform API?

Yes. Suggest you use NvBuffer APIs in nvbuf_utils.h
