ORTS is a StreamControl ripoff with an opinionated set of quality-of-life features:
Visible diff & easy undo: Changes not yet applied to stream are highlighted and can be discarded with the Discard button (duh).
Player name + country import: Currently supports smash.gg. data is saved as a csv file which can then be updated manually using any (decent) spreadsheet editor.
Better player name lookup: Matches names containing your query rather than starting with (one of my pet peeves about StreamControl).
Cross-platform: Tested on Windows & Linux. Should work on OS X too but I don't use it so you're on your own.
Stable builds for 64-bit Windows can be found in Releases.
I used to provide Linux builds but glibc/fontconfig versioning shenanigans put me off.
Also I only run streams on Windows so it's just not worth the effort anymore.
It definitely runs on Linux though, since that's where I primarily develop ORTS on.
Simply pull the code & run
poetry install --no-dev, then
Requires python >= 3.7 because we need the added-in-3.7
I also use poetry, so instead of pip, just run
poetry install to install dependencies.
