Only update ulMaxNumDecodeSurfaces if necessary. As for the stutter , I can't tell for sure , maybe it's a race condition somewhere in the driver. 402d98c decoupled cuvid parser and decoder number of decode buffers , with parser buffers set to be always CUVID_DEFAULT_NUM_SURFACES (5). In NVDEC Programming Guide they recommend setting an equal number of buffers for parser and decoder. Here are my test outputs and logs , edited memory pointers for better files comparison : https://drive.google.com/drive/folders/1f0ehcNxQV-0sMvm2g66J97kHxAGeRKUT
