The MP4drop tool outputs an ISO base media file format file (such as MP4 and MPEG-DASH files) to human-readable XML format.

In particular, it is capable of parsing boxes specific to Dolby AC-4 (ac-4, dac4) contained in the container file and outputting readable information in XML format. By examining the output XML file manually, you can verify that a content creation product can properly multiplex Dolby AC-4 bitstreams into MP4 files or ISO base media file format based online delivery formats.

This tool is supplied in Microsoft Windows 64-bit binary form, Linux 64-bit binary form, CentOS 64-bit binary form, and macOS binary form.
