The symptoms vary from an ok channel change, to video with no audio, vidio with wrong audio (subtitle fails) to ""cannot open decoder"". It seems that codec detection for LiveTV is having problems with certain channels, where mp3 codec is detected. It is particularly noticeable for Sky News channel. The issues are also present on mythtv 29, so the recent bump to ffmpeg 4 in master does not seem to be the cause. mythtv 0.28 works but also has the Ring Buffer detection issues, but channel change is ok. Note Channel switching times are also long due to Ring Buffer detection not failing, it falls back to in-file. Attached are a number of debug logs including ffmpeg, mythffmpeg and mediainfo data taken from a recording of Sky News channel.
