I build cuda samples install by cuda installer,then I build nvJPEG_encode success on my platform:
Driver 440.82 CUDA Version:10.2,I run success by call:
./nvJPEG_encoder -i src/ -o out/ -q 100 -s 420 -fmt rgbi
I had test several image success,then I test a image with size[8500*5667],call:
./nvJPEG_encoder -i src/ -o out/ -q 100 -s 420 -fmt rgbi
then abort, then I modify code print mem alloc/free msg:
`int dev_malloc(void **p, size_t s) {
int ret = (int)cudaMalloc(p, s);
printf("cudaMalloc %d ret=%d\n",s,ret);
return ret;
}
int dev_free(void *p) {
int ret = (int)cudaFree(p);
printf("cudaFree %p ret=%d\n",p,ret);
return ret;
}`
I can see that when encode yuv cudaFree return 716 which means cudaErrorMisalignedAddress,but when encode rgbi it abort at nvjpegEncodeRetrieveBitstream.
how can I resolve this probrem? please help me

then I build program then run with this message:
