ffmpeg command used for Optimize feature

General Discussions

Say I ran the following optimize settings : Custom -> Universal TV -> 4 Mbps, 720p

Does anyone know the full ffmpeg command this would invoke?

Nah but I believe if you run that and check your Plex Media Server.log file you can probably find it it looks something like this:

This is just a transcode job for remote playback but they probably all look the same…

If you are after a quality option for the transcoder:
Settings - Server - Transcoder - ‘Show Advanced’ - “Background transcoding x264 preset”
The “slower”, the better the quality.

Thanks, that should work for my purposes.

Useful info but I’m actually looking to automate transcoding beyond what PMS can do, so I don’t intend to ever use its transcoder.

Thanks but those instructions are for Windows and I’m running an Ubuntu server, plus his download link is broken. I already have a setup with sickbeard mp4 automator anyway—just trying to get my mp4 conversion just right which is why I’m interested in what Plex uses.

This is a Python script. It uses ffmpeg. These things are available on Linux and should even be installed by default.

I’m well aware of that, having sunk quite a bit of time tinkering with both ffmpeg and sickbeard mp4 automator in the past few weeks.
