ffmpeg-quality-metrics VS Tautulli

Have you seen ffmpeg-quality-metrics? I went with the docker option. I figured that would keep it simple with ffmpeg versions/whatever.

I'm not good at computers, so I love ffmpeg-quality-metrics. I use the docker version because I didn't want to fight with dependencies.

There are even tools that can compare the quality for us, like ffmpeg-quality-metrics can give a VMAF score as used by Netflix for the visual quality difference.

You can at least test the quality difference between two encodes with something like ffmpeg-quality-metrics. If it has a high VMAF score and saved a bunch of space for something that doesn't need to be perfect, then I consider it fine.

ffmpeg-quality-metrics is nice for comparing quality between copies. Better than squinting at pixels IMO.

If you're re-encoding video then ffmpeg-quality-metrics is a great tool IMO. Can give you a scale from 0-100 of how similar it appears based on SSIM or VMAF. If I get a VMAF in the high 90's, like 95+, then I know the encode is decent and if it saved significant space (if that's the goal?) then it's a keeper.

It's working. I found this [model](https://github.com/slhck/ffmpeg-quality-metrics/blob/master/ffmpeg_quality_metrics/vmaf_models/vmaf_v0.6.1neg.json) with the help of u/Felixkruemel and I specified the vmaf path in av1an using `--vmaf-path=path to the/vmaf/model.json"`

Then, after the encode, if you want to compare original vs encoded quality there's ffmpeg-quality-metrics which makes it easy to get VMAF & SSIM scores between the two.

ffmpeg-quality-metrics is a good tool to compare before & after encodes. It can easily calculate VMAF & SSIM scores. If I understand it correctly (I might not), then anything in the high 90s for VMAF is considered hard-pressed to be able to tell. Sometimes it hits 100, which makes me fairly confident about those encodes.

idk. When I did a re-encode with CRF 23 and preset 'veryslow' it went down to 2,236 kb/s. When I do a VMAF and SSIM test with ffmpeg-quality-metrics I was getting decent scores. It takes the file size down to 2.1GB. So my guess is they either set a significantly lower CRF or set a manual bitrate and aimed for the moon.

With Tautulli you have a better monitoring system than what Plex offers. Streaming history split by user, you can add notifications to a lot of services like Slack, email and so on. You can even create newsletters being sent out to users based on what was added to your server.

> How hard is this to configure?

Not at all. Just ensure that you have WoL enabled on the host machine and than proceed to send a magic packet. You could even do this with Home Assistant [1] if you are into that. I did this with a script that used tcpdump to monitor for incoming traffic [2] for Plex with an additional (dummy) Plex server on the Pi. I also remember faintly that I had to add 1 library and 1 video file to make this work though.

Powering down - or sleep - is a bit harder. I built a 'Sleep on LAN' app [3] for myself years ago that could power down (or sleep) a system on demand using a REST API. I used this and Tautulli [3] with Home Assistant that would check if there were any active streams and if there wasn't any activity for a specified amount of time I would send a SoL request to my service.

As you can see it isn't super hard or complicated, but a bit cumbersome to find all the moving bits and make it work. But when it does, it's IMHO fantastic.

In that case then I don't think there will be an easy way to transfer the metadata unfortunately (outside of some user-created script). One option that would at least help with the manual re-entry would be to use Tautulli's export feature or WebTools-NG's ExportTools to create a spreadsheet that has all the information in one place, and should be easier to copy/paste.

Also, take a look at Tautulli, tautulli.com. Its dashboard has more info than Plex. It shows transcode speed (1.0 = real time) and if subtitles are burning/transcoding/etc.

Tautulli for monitoring and notifications, plus some scripts for "maintenance," such as killing 4K transcodes and stopping remote streams after they've been paused for X minutes. These are from the JBOPS repository.

Tautulli. There's a feature where you can trigger notifications from events on your server, not just when it's down. I'm not sure there's a function to get your server to auto restart though.

Looks like Tautulli's mobile companion app.

The data Tautulli exports is great if you want to throw it in Excel to analyze your library, or as a backup of all the content you have on your server, but isn't really meant to be imported at a later date (the exporter guide. You should instead follow the Move an Install to Another System guide to move your server data to a new machine.

I enjoy https://tautulli.com/ for looking at my server's stats
