The freeze is accompanied by 'Fragment sequence discontinuity' and 'needrestart' log messages, triggering a demuxer restart. The bug was confirmed across 20 test videos in both VLC 3.0.18 and 3.0.23, and reproduced outside the app by opening URLs directly in VLC — ruling out any KMP or vlcj integration issue. Progressive MP4 plays without issue. The workaround adopted was to default the Desktop app to progressive MP4 playback, keeping HLS/DASH available only in a diagnostic mode. ## Full article daily.dev links to this article rather than hosting it.
