VMAF CUDA vmaf_cuda_picture_free() Assertion 0 failed

[ha7sh17]

hi. there

We have identified that when using the libvmaf_cuda(vmaf-3.0.0) filter with ffmpeg in a constrained virtual memory environment, an assertion failure occurs in vmaf_cuda_picture_free() when ffmpeg terminates.

You can easily reproduce the issue by running the ffmpeg command with the libvmaf_cuda filter along with ulimit -v 16777216. (16777216 represents 16GB, which is a sufficient size for virtual memory.)

ulimit -v 16777216;ffmpeg -i a.mp4 -i b.mp4 -filter_complex "[0:v]hwupload_cuda[main];[1:v]hwupload_cuda[ref];[main][ref]libvmaf_cuda=log_fmt=json:log_path=vmaf_log.json" -f null -
