rPi 3, LE 7.0.1. When 59.94fps video is playing with 8-channel software decoding (DTS, DTS 24/96, DTS-HD:MA, Dolby TrueHD) I experience heavy frameskipping. No frameskipping when audio passthru. No frameskipping in 50 or 24 fps videos. A bug, or I'm doing something wrong?
59.94fps and 8ch decoding = Missing frames
