Hello, I'm not very familiar with transcoding. I want to use hardware acceleration for my new emby server. My old emby server was installed on a single board computer. With 2 simultaneous streams the Cpu was throttling and at 100%. Because the Cpu on the new server should mostly be used for other tasks, I decided to use a dedicated gpu for media transcoding. My understanding was that emby almost exclusively uses decoding and only need encoding for tasks like converting files. But this seems to be wrong. I read in some threads (e.g. https://emby.media/community/index.php?/topic/62545-video-card-advice-for-hardware-transcoding/)that the consumer grade nvidia cards only support 2 simultaneous encoding streams/sessions (decoding is unrestricted). After this hint I also noticed this in the support matrix on nvidia website. Now is my question: Whenever transcoding is necessary does emby also need one encoding stream for one decoding stream? My new understanding is that emby uses decode to convert the current file codec to raw video/audio data and then uses encode in order to turn this raw video/audio data to a more compressed version supported by the streaming client, because the raw video/audio would use a way to much bandwidth for streaming. And if the two gpu encoding streams are exhausted, does emby then simply use the cpu for further encoding? Additional info/ off topic: There will be a maximum of 8-10 simultaneous streams on my new server. I plan to buy the new Gtx 1650 which was released 3 days ago. I will buy this card in around 1-2 months. I think the price of this card will drop much in the near future because it is a horrible value card for gamers (rx570 is ~30% much better at ~10% lower price, most reviews advise against this card for gaming and declare it 'dead on arrival'). But looking at the matrix for supported hardware codecs (https://developer.nvidia.com/video-encode-decode-gpu-support-matrix) this card fully supports every decoding codec (H.264/H.265/VP8/VP9/...) and almost every encoding (no hevc b frames). And whats quiet important for me, this card draws only around 75W and is really silent. Thank you English is not my native language
