• Fixed HLS writing an incorrect init segment if segments are sparse (not all tracks occur in every segment)
• Fixed encodability checks throwing on Safari in some cases (#456)
• UrlSource now honors maxCacheSize even if the server responds with 200; plus it slows down response consumption in this case (#457)
• Improved VideoSample mipmapping for resizing
• Improved video/audio decoder config validation
• Fixed Input.getFirstTimestamp() for files with zero-packet tracks
• Fixed incorrect traf indices being written in fMP4 files with sparse fragments (not all tracks occur in every fragment)
