thanks a lot for the marked improvements !

for dynamic resolution, maybe add a check ?

ctx->support_dyn_res = nvenc_check_cap(avctx, 
NV_ENC_CAPS_SUPPORT_DYN_RES_CHANGE);

and:
if (dw != ctx->init_encode_params.darWidth || dh != 
ctx->init_encode_params.darHeight)

==>
if ( (dw != ctx->init_encode_params.darWidth || dh != 
ctx->init_encode_params.darHeight) && ctx->support_dyn_res)
