What is DumpTS?

DumpTS is a simple utility tool to process the multimedia files packed into main-stream multimedia container formats, which provides these kinds of features:

Extract and repack the elementary stream data or PSI sections data from TS, ISOBMFF, Matroska and MMT/TLV file
List the primitives hierarchical elements or meta w or w/o filter, and show the syntax, semantic, payload hex-view, bit offset and count, and so on, then assist to look inside the media essential of any given media file
Show media information of elementary streams(AC3/DD+/MLP/DTS/DTS-HD/MPEG2-AAC/MPEG-4 AAC/MPEG2 Video/H.264/H.265/AV1…), ISOBMFF box, Matroska EBML element and MMT/TLV and TS packet/message/table/descriptors, container layout, …
Re-factor a TS stream file in place
Extract some elementary streams, and reconstruct a partial TS file
Show decoder HRD model information for any codec stream, ATC/PCR/pts/dts and so on, and do the related verification
Provide some utility features for ISOBMFF file reconstruction
Provide some utility functions for codec and container technology, for example, Huffman Codebook, CRC, container layout…

How to run it?

Usage: DumpTS.exe [MediaFileName] [OPTION]…

The option parameter pattern is like as

--option_name=option_values

In the option, if one parameter value has multiple parts, each part can be delimited with the characters of .;,:. As for the detailed option syntax, please see Option Syntax.

Here are some examples of command lines:
