I have a live presentation where the encoder was not sending data for different times for audio and video. For example: Audio: 1, 2, 3, -, -, 6, -, -, 9 Video: 1, 2, 3, -, -, -, -, -, 9 Should the packager emit 2 discontinuity tags for audio or just discard timestamp 6 and merge them into 1 discontinuity? Section 8.15 of the HLS authoring spec says: "All variants and renditions MUST have discontinuities at the same points in time." Does this mean that for audio/video and text variants all need to align? However the documentation for EXT-X-DISCONTINUITY-SEQUENCE seems to imply that a/v may not necessarily have the same count of discontinuities. Please clarify which is correct and how the packager should have emitted the discontinuity tags above. Thanks!
