[Feature] Call external program after download

[NoDowt]

Current Situation

Currently there is no option to configure any post-processing of files automatically.

Suggestion / Feature Request

Some people may find benefit to having the ability to post-process files via an external program.
An example could be to call something (e.g. musicbrainz Picard) which could update metadata with additional info not available from Tidal (e.g. genre); or transcoding the files to another format.

This is probably beyond the scope of this app. The idea of this is app so far is to have a simple downloader. But feel free to submit pull requests.

@NoDowt : Actually I would (and do) it the other way round, embed the calls of tidal-dl-ng into another script because there I can do whatever I want with it. As exislow mentioned there might be countless cases of what people would want to call afterwards. You might be way better off this way.

[NoDowt]

@crankedguy Currently I just use the Exe/gui version, and have used other GUI front ends for different tools (not related at all to Tidal) that include a generic post-processing option that can be set to run any command line program.

Figured it might not be too hard to include here; but then I’m not familiar with Python & how easy/hard it would be to run external programs afterwards (and account for the different OS’s).

Not something that’s critical of course, and wrapping the cli version of this in a script could be the better option. If I ever find the time I might use this as a learning opportunity to figure out Python and see if I can add this in though 🤷🏼‍♂️

@NoDowt : Dude I believe in you! If you can call a python script, and can use Google, it might take you half an hour to figure that out, just google for subprocess.run, calling another program from Python is a oneliner...
without any checks on what the prog returns etc. but just the basic call that is
Python is beautiful, I grew up with Assembler and C, and I use Python almost exclusively for everything nowadays except where I cannot (because there is no environment, API for it etc) or where performance is absolute crucial/hardware access, then C it is...

The problem is that those downloaded m4a files are not usable with DLNA to WIIM streamer, if I use FooBar it works and with their downloadable encoders I use flac.exe to convert m4a to flac without loss. So yes , a extra commandline would be appreciated where you can run your own command with parameters, thanks in advance.

[crankedguy]

You do net need to convert anything, as the full working flac is already inside the m4a container. And as far as I saw @exislow already created the correct way to get this flac out now as an extension with a parameter setting, which is to use ffmpeg with -acodec copy

I've the windows downloader, so how do I use it? Tried about everything and none of the downloaded files are working. I see only option to extract from MP4
