Fix HLS writing an incomplete init segment for sparse segments, improve decoder config validation, fix getFirstTimestamp() for Inputs with zero-packet tracks, allow zero-track muxing for some formats that allow it, add new track metadata that allows you to specify the decoder config early (enables zero-packet tracks), fix trafIndices in sparse fragmented MP4s, fix assertion errors in MPEG-TS demuxer
