Add CLI option to save the final file as ts, which is output.ts, so no conversion to mp4 or mkv with ffmpeg or cat:

$ TwitchDownloaderCLI videodownload --oauth $OAUTH -u "https://www.twitch.tv/videos/694444624" -q best --temp-path ./TMP/ -o SURPRISE.ts

That would mean just copying output.ts to SURPRISE.ts in this case maybe detect file extension automatically to determine if use ffmpeg/cat or not?

Or just manually set it:

$ TwitchDownloaderCLI videodownload --format-ts --oauth $OAUTH -u "https://www.twitch.tv/videos/694444624" -q best --temp-path ./TMP/ -o SURPRISE.ts

The flag could be formatted as --format-ts, --format:ts or --format ts like other software does.

Also please add such information to documentation.

Once this feature is implemented, I can ask better ts support from handbrake and gpac.

The finalization pipeline has changed and output.ts is no longer created.
