Emby server seek-speed

[bLight 2]

Hi Emby team,

I'm the developer of Zoom Player and I'm writing client code for both Emby and Plex.

One thing I noted is that performing any operation (seeking, switching embedded subtitle track) on the stream (no transcoding) using LAV Source Filter (A DirectShow wrapper for ffmpeg and other open-source media projects) is very very slow on even a local server, taking between 3-15 seconds for each action. It's better if I use libVLC as the media engine, but then I lose a lot of the functionality available only through DirectShow.

Surprisingly, these operations are much faster when using a Plex server (again, on the same PC as the Emby server, streaming the exact same media file with no transcoding).

I verified this issue is not specific to my PC, I've had several people test it against several servers.

Is there anything that can be done to improve the performance?

P.S.
It's less noticeable if you're on a high-end machine.

Unfortunately, I can't quite quantify what's going on because the issue isn't as bad on a local server. I'll try to create a video showcasing the issue when/if I get a better handle on it.

OK that would be great. Thanks.
