Include ccextractor in Docker images

[Ranbato]

May be i niche request, but I transcode the .ts files in my Postprocessing.sh and before I do that i extract the subtitles/closed captions with ccextractor so they aren't lost.

I currently add it myself to the docker image with the following Dockerfile:

Code:

FROM nextpvr/nextpvr_amd64:stable AS updated_base

I'd rather not have lots of extra stuff added to the Docker image, and this coming from the person who also does a custom Docker image with Python3 in it. I think if sub starts including all these requests in the Docker image it will end up being a huge, bloated beast. And he'd have to test and support everything included. Best to have those of us that need more add it ourselves. If you're so inclined, you could publish your image to Docker Hub so others could use it if they wanted to (I did that with mine).

[Ranbato]

That's not a bad idea. Maybe I'll do that and that will also provide a way to gauge interest.

docker pull marklambert/nextpvr-ccextractor:latest

I wouldn't use docker anymore it was nice at the beginning, but if you include ccextractor you should include comskip and consider other post processing tools

I used to use comskip years ago but I could never get it reliable enough. I have got pretty good at Kodi's skip functionality now and just do it manually while watching the shows.
It wouldn't be hard to add.

What other tools were you thinking?

(I've decommissioned my Windows server so I'm running everything on my Synology NAS so it has to be Docker for most things)

[mvallevand]

If you are putting an image out for public distribution you might want to ask others I see handbrake, comskip, comcut, and ccextractor often mentioned.

For me, ccextractor and sqlite3. I use both, along with mediainfo for post processing. Your custom container(s) are much appreciated!

[Ranbato]

The latest version has ccextractor, sqlite3, and comskip added.
I'll take a look at comcut and handbrakeCli too.

[Ranbato]

I have comcut and HandBrakeCLI done too, but now I have gone down the rabbit hole of building ffmpeg to add a few things in and that is sending me down a rabbit hole. Hopefully I'll have it working in a few days.

[Ranbato]

ffmpeg is now building with custom, up-to-date libraries including Netflix's VMAF quality library and I'm going to adjust handbrake to use the latest as well.

As a side effect, I'm installing python3 for the builds so I may look at keeping that in if anyone is interested (pkscout).

I should have a new image up in a few days.
