Fix incomplete transcode target codec implementation

- Add transcode target codec logic to get_play_url function
- Add debug logging to track codec selection
- Remove redundant enable="true" attributes in settings.xml

The get_play_url function was still using hardcoded h264, which caused
the transcode target codec setting to not take effect for direct
transcode URLs.
