I want to start the Media Server Software on demand.
I thought that I had seen a setting, now I can’t find it.
My other question is that I loaded a Movie and now it’s Transcoding from AC3 to AAC.
Why is it doing that automatically and how do I stop that?
Need to disable auto-play globally.
what do you mean with “on demand”?
For Plex to work, you’ll need to run the Plex Media Server application. If there’s no clients connected, your OS will let the app sleep until there’s requests coming. For Plex to only start when you open a client, you’d need another application running in place of the PMS to monitor those requests and start the server (which is sort of redundant).
Transcoding depends on the capabilities of your client (or what the client OS tells the Plex Client it’s capable of). If your client e.g. supports AC3 but only for a certain amount of channels or max bitrate, Plex will transcode it to match that limit – if the client prefers AAC over transcoded AC3, the transcoding target will be AAC.
Sometimes transcoding is also triggered by how you’ve configured the client. You can e.g. check if you allow your client to direct play or direct stream – or if you have e.g. required it to go for a certain quality level when streaming in a certain environment (e.g. via mobile / the internet / your home network…
I only want PLEX Media Server to only start on my system when I click on it, hence, on-demand.
Right now, it is playing a movie and I didn’t request it, so I want to stop that as well.
This is strictly on-demand. Nothing is stored. The type of player and the selected audio track and the available network bandwidth are all considered before the decision is made to transcode or not.
That is how Plex is working. And it won’t ask. Don’t forget: Plex is a server. It can server remote clients. It can serve clients running on a set top box or a mobile phone. If it should ask before each of these tasks, then you might as well hand out the files to play manually.
So it would run only when you asked. I have been running Plex for many years now and there are no issues on a iMac i5 bogging down unless your trans coding more than 2 Titles. Check running your Plex server with a few common apps that you use with your task manager.
With Plex server also make sure you don’t have Video Preview Thumbnails enabled in Library settings and scheduled tasks are not at a time when you need you computer for other tasks.
