Hi,
I use a4ksubtitles as my subtitle provider and have noticed that for certain movies it fails to search for subtitles, instead displaying “IMDB ID is not provided”. Initially I thought this was either due to the scraper not finding an IMDB ID for more obscure movies or a bug within a4ksubtitles itself – but after taking a look at the database myself, all affected movies do indeed have an IMDB ID associated with them. Looking into it further, I found that a call to xmbc.getInfoLabel("VideoPlayer.IMDBNumber") inside the addon will instead return the TMDB ID for the affected movies, even though the IMDB ID is available. Unfortunately despite following the build guide I couldn’t get a debug build to work to debug or fix the issue within xbmc myself, though admittedly I’m probably out of my depth a little there.
Regardless, I suspect “VideoPlayer.IMDBNumber” should not be returning a TMDB ID?
