HLS audio gets shortly muted on discontinuity
Hello,I'm using HLS to create "unique" videos:- I have a stock of video sequences (segments)- I build a playlist dynamically (based on user's inputs)My segments are video-only 4 seconds ffmpeg-encoded .mp4 files, mp4box-prepared.I declare #EXT-X-DISCONTINUITY between each segmentThe audio is "separated" (#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio"...)I chunked the audio to make its playlist "discontinued" as well, so that the video discontinuity matches the audio discontinuity.My problem is:(EDIT:) in HTML environment on Safari, on both MacOS and iOS.I get a short audio mute (about 0.2 seconds) on each discontinuity.(I also tried 3.84 seconds of 25fps video + 48kHz audio, but maybe I didn't do it properly ?)My question is:is it possible to have NO audio mute (at all) on discontinuity, or is it "decided" (that a gap will be inserted) to prevent audio glinchs ?If not, how can I get a seamless output stream ?
