Comment (by malakudi):

 Then hwaccel nvdec cannot be used for workloads that run multiple realtime
 transcodes. Having the gpu power to do more realtime transcodes but
 spending vram on buffers that are not really needed in specific workloads
 (since cuvid works fine without them) is not a good deal.
