Probably since version 5.5.3 or 5.5.2 (maybe sooner, but this is the first time i noticed it) some files are not playing anymore. They are videos in MKV container, encoded in h264, however 1080i, created as native capture of DVB-T broadcast. These files were working for a long time before you probably made changes because of h265 support or tvOS 11 support. Is this a known bug or a bug you could fix? I could provide you some sample file if you need it.
These problems occur on both Apple TV 2015 and Apple TV 4K .
To specify : not playing, in this case, means that there is no error shown, only a black screen with all controls, length of the video is correctly loaded and position on the time axis is jumping 10s per second.
MKV on Synology NAS → AppleTV 4K → Infuse = not working? ?
MKV on Synology NAS → iPad > Infuse = working
MKV on Synology NAS → iMac 4K > Infuse = working
