It's better described in https://github.com/google/shaka-player/issues/1572#issuecomment-420356595 as I originally thought it was a shaka player issue. When watching this channel in mcast, there seem to be no issues, also nor ffmpeg nor packager reports any errors. \r\n\r\nNot really sure how to reproduce this on your side, please let me know if you need anything from us. Do you think this could be caused by shaka packager or an issue in the content?\r\n\r\nThank you\r\n\r\n"}}
