Hi NVIDIA, I’ve been trying to use NvBuffers directly with VPI 1.2, but I can only upload NV12 and ABGR32. If I try to use any other format vpiImageCreateNvBufferWrapper will fail. When using GRAY8 specifically I get the following log: NVMEDIA_ARRAY: 53, Version 2.1 NVMEDIA_VPI : 172, Versio…

Hi, Did you have any dependency on JetPack 4.5.1? If not, it’s recommended to use the latest JetPack 4. Thanks.

Hi, Would you mind sharing a simple source to reproduce this on VPI 1.2? Since NvBuffer is deprecated in rel-35, we need to check the wrapper in detail with our internal team first. Thanks.

Hi @AastaLLL , Thanks for your response. Here is a simple code that reproduces the issue. example.c (1.2 KB)

Hi, We test your source on JetPack 4.6.2 with VPI 1.2.3. The test can work without issue: $ g++ example.c -o out -I/usr/src/jetson_multimedia_api/include -L/usr/lib/aarch64-linux-gnu/tegra -lnvvpi -lnvbuf_utils $ ./out NVMEDIA_ARRAY: 53, Version 2.1 NVMEDIA_VPI : 172, Version 2.4 Returned w…

Thank you very much. However, I think I mixed up the VPI version since I was reading the documentation for VPI 1.2. Could you also test this source with JetPack 4.5.1, please? I’ll also be testing with 4.6.2 to see if it suits our needs
