I'm getting this as well. Release 20210210 works and 20220728 always segfaults.

This seems to happen independent of the command line parameters, so long as any kind of frame interpolation is attempted it fails before the first frame.

I've run dain-ncnn-vulkan in my debugger, it segfaults after this call into NCNN:

It looks like ncnn::create_layer() returns nullptr because it has no layer_creator for layer no. 27 (Reshape). Both layer_registry and layer_registry_avx have other layer_creators, but are empty on index 27.

(Tested on Gentoo Linux AMD64, Intel Xeon v1 w/AVX and NVidia RTX 3090 w/Vulkan Compute and CUDA 11 working)

I looked a bit further and was able to make it work.

Looks like dain-ncnn-vulkan explicitly sets NCNN's WITH_LAYER-reshape to OFF. Turned it ON gets rid of the nullptr and dain-ncnn-vulkan works again!

I also encountered the same problem. Can anyone tell me how to solve it?

Thank you very much! That solved the problem for me, too! (Ubuntu 22.04)

thanks very much for your solution, but i'm like a coding noob and don't know exactly how to turn that WITH_LAYER-reshape on, if you or anyone could help me out i would be eternally grateful.

Modify the src/CMakeList.txt file before compiling. It's already in there, just change the OFF to ON. But you must compile it from source. At least for Linux, this bug also crashes the prebuilt version.
