mkvmerge(1) will automatically remove all elements not allowed by the specification.

The DocType header item is changed to 'webm'.įor chapters and tags only a subset of elements are allowed. The only allowed codecs are VP8, VP9 video and Opus, Vorbis audio tracks. This is also turned on if the output file name's extension is 'webm'. See the explanation for the -split option for details. If splitting is used then this parameter is treated a bit differently. Please read the section 'Option order' if you're new to the program. The order of command line options is important. This program takes the input from several media files and joins their streams (all of them or just a selection) into a Matroska(TM) file see the Matroska(TM) website.
