I have my media library stored on another computer, and access it in Kodi via sftp. It contains standard media files, Blu-ray folders (BDMV), and DVD folders (VIDEO_TS). The former two work properly, but the latter does not. Attempting to play VIDEO_TS.IFO results in nothing appear to happen, while the following lines are recorded in the log (slightly redacted): 00:10:16.664 T:140637897098624 NOTICE: VideoPlayer: Opening: sftp://USERNAME@file-host.local:22//path/to/VIDEO_TS/VIDEO_TS.IFO 00:10:16.664 T:140637897098624 WARNING: CDVDMessageQueue(player)::Put MSGQ_NOT_INITIALIZED 00:10:16.664 T:140635281553152 NOTICE: Creating InputStream 00:10:16.711 T:140635281553152 ERROR: Error on dvdnav_open 00:10:16.711 T:140635281553152 ERROR: CVideoPlayer::OpenInputStream - error opening [sftp://USERNAME@file-host.local:22//path/to/VIDEO_TS/VIDEO_TS.IFO] 00:10:16.711 T:140635281553152 NOTICE: CVideoPlayer::OnExit() 00:10:16.712 T:140637897098624 ERROR: Playlist Player: skipping unplayable item: 0, path [sftp://USERNAME@file-host.local:22//path/to/VIDEO_TS/VIDEO_TS.IFO] I tried manually building Kodi from the source tarball, and it worked properly, so it would appear that the problem is in the ebuild. (Perhaps in the way the libdvd* libraries are set up for the build?) Note that ebuild-installed version will play DVDs from the local DVD drive (as long as I mount the disc, first), just not from the network location.

Can you please try again with the latest Kodi version (currently media-tv/kodi-18.0_beta5)? Kodi 17 is no longer supported upstream, but 18 is - so if this issue persists, we can try to work with upstream to fix it.
Kodi 17 is no longer in Gentoo; if this issue is reproducible using a version currently in Gentoo, please reopen. Thanks!
