Replace string with another in m3u

[ovalseven]

The ability to replace stings in channels that are added daily would allow for custom tags, logo additions and other benefits.

Could something like this be implemented?

for sure! This is definitely possible, but I'm not sure I'm totally following.

I see in the Channels forum they are mentioning using it to set a logo IF channel title contains X. And in the Git link, they are talking about URL substitution.

If you could give me a couple scenarios I'll do some digging and see what I can come up with...

I'm looking for something similar.
My specific use case would be a "pre-processor" executed when the upstream feed is refreshed.
I'd like to be able to apply regex find/replace to any field.

The main thing would be to replace logo urls with a local volume using regex.

Example:
Original Logo: http://sketchyserver.example.org/images/logo-filename.png
RegEx Match: (?:https?:\/\/)?[^\/\s]+(?:\/[^\/\s]+)*\/([^\/\s]+)

RegEx Substitution: http://m3u-editor:36400/logos/$1
New Logo: http://m3u-editor:36400/logos/logo-filename.png

Obviously the above example could be a feature in itself, where it would download the source logo to a directory and update the URL to itself. But with a regex pre-processor, I could just grab the images myself and upload the directory.

In my case, my channels have no logos in my provider's m3u or epg. And since new channels are added/removed each day by my provider, there's no way to add them. "Set a logo IF channel title contains X" would work great for that.

Maybe it could work for adding custom Channels DVR tags to like, IF group-title="NBA" then add text tvc-guide-placeholders-grouping="Sports"?

I updated m3u-editor and see that it now uses placeholder.png for channels that have no logos. The ability to pick my own image for the placeholder would solve my problem without the need for any string matching.

You can already do this by clicking the Edit icon on a channel from the Channels section.
There is an Icon field where you can put in the URL for your own image.

That doesn't work well when your provider adds new channels every day and they don't have logos. You'd have to open the app and edit them every day.

This was my reason for requesting the "replace string" feature.

I'll look into adding a custom logo options. As to the logo being updated, it's only set on initial sync (to the provider URL or empty), on subsequent syncs the logo is not updated so your changes won't be overwritten
