Comment (by maxfs79):

 That's right, but when added two strings:
 +            p_nvenc->nvEncUnregisterResource(ctx->nvencoder,
 ctx->registered_frames[tmpoutsurf->reg_idx].regptr);
 +            ctx->registered_frames[tmpoutsurf->reg_idx].regptr = NULL;

 GPU adapter begin to work slowly when load encoder to 80-90% :(
