tsMuxer

Vision

This project is for tsMuxer - a transport stream muxer for remuxing/muxing elementary streams. This is very useful for transcoding and this project is used in other products such as Universal Media Server.

EVO/VOB/MPG, MKV/MKA, MP4/MOV, TS, M2TS to TS to M2TS.

Supported video codecs H.264/AVC, H.265/HEVC, VC-1, MPEG2. Supported audio codecs AAC, AC3 / E-AC3(DD+), DTS/ DTS-HD - please note TrueHD must have the AC3 core intact.

Some of the major features include:

  • Ability to set muxing fps manually and automatically
  • Ability to change level for H.264 streams
  • Ability to shift a sound tracks
  • Ability to extract DTS core from DTS-HD
  • Ability to join files
  • Output/Author to compliant Blu-ray Disc or AVCHD
  • Blu-ray 3D support

Ethics

This project operates under the W3C's Code of Ethics and Professional Conduct:

W3C is a growing and global community where participants choose to work together, and in that process experience differences in language, location, nationality, and experience. In such a diverse environment, misunderstandings and disagreements happen, which in most cases can be resolved informally. In rare cases, however, behavior can intimidate, harass, or otherwise disrupt one or more people in the community, which W3C will not tolerate.

A Code of Ethics and Professional Conduct is useful to define accepted and acceptable behaviors and to promote high standards of professional practice. It also provides a benchmark for self evaluation and acts as a vehicle for better identity of the organization.

We hope that our community group act according to these guidelines, and that participants hold each other to these high standards. If you have any questions or are worried that the code isn't being followed, please contact the owner of the repository.

Language

tsMuxer is written in C++. It can be compiled for Windows, Linux and Mac.

brew install freetype
brew install zlib

Usage

GUI

The simplest thing to do is to use the tsMuxerGUI. A screenshot of that can be seen below:

tsMuxerGUI_Screenshot

Command Line

Alternatively you can use tsMuxer via the command-line.

Examples:

    tsMuxeR 
    tsMuxeR  

tsMuxeR can be run in track detection mode or muxing mode. If tsMuxeR is run with only one argument, then the program displays track information required to construct a meta file. When running with two arguments, tsMuxeR starts the muxing or demuxing process.

The output of the program is encoded in UTF-8, which means that non-ASCII characters will not show up properly in the Windows console by default. If you want to see the output properly, run

chcp 65001
before running tsMuxeR.

Meta file format

File MUST have the .meta extension. This file defines files you want to multiplex. The first line of a meta file contains additional parameters that apply to all tracks. In this case the first line should begin with the word MUXOPT.

Encoding

The file should be encoded with UTF-8. However, since older versions of the GUI saved the file in the "active code page" encoding on Windows, it is used as a fallback on this platform. In the very rare event of the program not being able to open some files referenced by a meta file saved with an older GUI version, please convert it to UTF-8 manually by opening it in Notepad and selecting

ANSI
as the encoding, and then saving it via "Save As", but this time selecting
UTF-8
as the encoding.

Syntax

The following lines form a list of tracks and their parameters. The format is as follows:

,   ,   
. Parameters are separated with commas, with each parameter consisting of a name and a value, separated with an equals sign. Example of META file:
MUXOPT --blu-ray
V_MPEG4/ISO/AVC, D:/media/test/stream.h264, fps=25
A_AC3, D:/media/test/stream.ac3, timeshift=-10000ms
In this example one AC3 audio stream and one H264 video stream are multiplexed into BD disc. The input file name can reference an elementary stream or a track located inside a container.

Supported input containers: * TS/M2TS/MTS * EVO/VOB/MPG/MPEG * MKV * MOV/MP4 * MPLS (Blu-ray media play list file)

Names of codecs in the meta file:

Meta File Code

Description
VMPEGH/ISO/HEVC H.265/HEVC
VMPEG4/ISO/AVC H.264/AVC
VMPEG4/ISO/MVC H.264/MVC
VMS/VFW/WVC1 VC1
VMPEG-2 MPEG2
AAC3 AC3/AC3+/TRUE-HD
AAAC AAC
ADTS DTS/DTS-Express/DTS-HD
AMP3 MPEG audio layer 1/2/3
ALPCM raw pcm data or PCM WAV file
SHDMV/PGS Presentation graphic stream (BD subtitle format)
STEXT/UTF8 SRT subtitle format. Encoding MUST be UTF-8/UTF-16/UTF-32

Each track may have additional parameters. Track parameters do not have dashes. If a parameter's value consists of several words, it must be enclosed in quotes.

Common additional parameters for any type of track:

Parameter

Description
track track number if input file is a container.
lang track language. MUST contain exactly 3 letters.

Additional parameters for audio tracks:

Parameter

Description
timeshift Shift audio track by the given number of milliseconds. Can be negative.
down-to-dts Available only for DTS-HD tracks. Filter out HD part.
down-to-ac3 Available only for TRUE-HD tracks. Filter out HD part.
secondary Mux as secondary audio. Available for DD+ and DTS-Express.
default Mark this track as the default when muxing to Blu-ray.

Additional parameters for video tracks:

Parameter

Description
fps The number of frames per second. If not defined, the value is auto detected if available in the source stream. If not, it defaults to 23.976.
delPulldown Remove pulldown from the track, if it exists. If the pulldown is present, the FPS value is changed from 30 to 24.
ar Override video aspect ratio. 16:9, 4:3 e.t.c.

Additional parameters for H.264 video tracks:

Parameter

Description
level Overwrite the level in the H264 stream. Do note that this option only updates the headers and does not reencode the stream, which may not meet the requirements for a lower level.
insertSEI If the original stream does not contain SEI picture timing, SEI buffering period or VUI parameters, add this data to the stream. This option is recommended for BD muxing.
forceSEI Add SEI picture timing, buffering period and VUI parameters to the stream and rebuild this data if it already exists.
contSPS If the original video doesn't contain repetitive SPS/PPS, then SPS/PPS will be added to the stream before each key frame. This option is recommended for BD muxing.
subTrack Used for combined AVC/MVC tracks only. TsMuxeR always demultiplexes such tracks to separate AVC and MVC streams. Setting this to 1 sets the reference to the AVC part, while 2 sets it to the MVC part.
secondary Mux as secondary video (PIP).
pipCorner Corner for PIP video. Allowed values: "TopLeft","TopRight", "BottomRight", "BottomLeft".
pipHOffset PIP window horizontal offset from the corner in pixels.
pipVOffset PIP window vertical offset from the corner in pixels.
pipScale PIP window scale factor. Allowed values: "1", "1/2", "1/4", "1.5", "fullScreen".
pipLumma Allow the PIP window to be transparent. Transparent colors are lumma colors in range [0..pipLumma].

Additional parameters for PG and SRT tracks:

Parameter

Description
video-width The width of the video in pixels.
video-height The height of the video in pixels.
default Mark this track as the default when muxing to Blu-ray. Allowed values are

all
which causes all subtitles to be shown, and
forced
which shows only elements marked as "forced" in the subtitle stream.
fps Video fps. It is recommended to define this parameter in order to enable more careful timing processing.
3d-plane Defines the number of the '3D offset track' which is placed inside the MVC track. Each message has an individual 3D offset. This information is stored inside 3D offset track.

Additional parameters for SRT tracks:

Parameter

Description
font-name Font name to render.
font-color Font color, defined as a hexadecimal or decimal number. 24-bit long numbers (for instance 0xFF00FF) define RGB components, while 32-bit long ones (for instance 0x80FF00FF) define ARGB components.
font-size Font size in pixels.
font-italic Italic display text.
font-bold Bold display text.
font-underline Underlined text.
font-strikeout Strikethrough text.
bottom-offset Distance from the lower edge while displaying text.
font-border Outline width.
fadein-time Time in ms for smooth subtitle appearance.
fadeout-time Time in ms for smooth subtitle disappearance.
line-spacing Interval between subtitle lines. Default value is 1.0.

Currently tsMuxer only supports fonts in TTF format. It also will only load fonts from

/usr/share/fonts/
on Linux and
/Library/Fonts/
on Mac. As such our recommendation is to use font "FreeSans" on Linux and "OpenSans" on Mac.

tsMuxeR supports additional tags inside SRT tracks. The syntax and parameters coincide with HTML:

, , , , 
. Default relative font size (used in these tags) is 3. For example:
Test
coloredtext

Global additional parameters are placed in the first line of the META file, which must begin with the MUXOPT token. All parameters in this group start with two dashes:

Parameter

Description
--pcr-on-video-pid Do not allocate a separate PID for PCR and use the existing video PID.
--new-audio-pes Use bytes 0xfd instead of 0xbd for AC3, True-HD, DTS and DTS-HD. Activated automatically for BD muxing.
--vbr Use variable bitrate.
--minbitrate Sets the lower limit of the VBR bitrate. If the stream has a smaller bitrate, NULL packets will be inserted to compensate.
--maxbitrate The upper limit of the vbr bitrate.
--cbr Muxing mode with a fixed bitrate. --vbr and --cbr must not be used together.
--vbv-len The length of the virtual buffer in milliseconds. The default value is 500. Typically, this option is used together with --cbr. The parameter is similar to the value of vbv-buffer-size in the x264 codec, but defined in milliseconds instead of kbit.
--no-asyncio Do not create a separate thread for writing. This option also disables the FILEFLAGNO_BUFFERING flag on Windows when writing. This option is deprecated.
--auto-chapters Insert a chapter every minutes. Used only in BD/AVCHD mode.
--custom-chapters A semicolon delimited list of hh:mm:ss.zzz strings, representing the chapters' start times.
--demux Run in demux mode : the selected audio and video tracks are stored as separate files. The output name must be a folder name. All selected effects (such as changing the level of a H264 stream) are processed. When demuxing, certain types of tracks are always changed : - Subtitles in a Presentation Graphic Stream are converted into sup format. - PCM audio is saved as WAV files.
--blu-ray Mux as a BD disc. If the output file name is a folder, a Blu-Ray folder structure is created inside that folder. SSIF files for BD3D discs are not created in this case. If the output name has an .iso extension, then the disc is created directly as an image file.
--blu-ray-v3 As above - except mux to UHD BD discs.
--avchd Mux to AVCHD disc.
--cut-start Trim the beginning of the file. The value should be followed by the time unit : "ms" (milliseconds), "s" (seconds) or "min" (minutes).
--cut-end Trim the end of the file. Same rules as --cut-start apply.
--split-duration Split the output into several files, with each of them being seconds long.
--split-size Split the output into several files, with each of them having a given maximum size. KB, KiB, MB, MiB, GB and GiB are accepted as size units.
--right-eye Use base video stream for right eye. Used for 3DBD only.
--start-time Timestamp of the first video frame. May be defined as 45Khz clock (just a number) or as time in hh:mm:ss.zzz format
--mplsOffset The number of the first MPLS file. Used for BD disc mode.
--m2tsOffset The number of the first M2TS file. Used for BD disc mode.
--insertBlankPL Add an additional short playlist. Used for cropped video muxed to BD disc.
--blankOffset Blank playlist number.
--label Disk label when muxing to ISO.
--extra-iso-space Allocate extra space in 64K units for ISO metadata (file and directory names). Normally, tsMuxeR allocates this space automatically, but if split condition generates a lot of small files, it may be required to define extra space.
--constant-iso-hdr Generates an ISO header that does not depend on the program version or the current time. Normally, the ISO header's "application ID", "implementation ID", and "volume ID" fields are set to strings containing the program version and/or a random number, while the access/modification/creation times of the files in the image are set to the current time. This option disables this behaviour by filling these fields with hardcoded values and setting the file times to the equivalent of
Wed 1 Jul 20:00:00 UTC 2020
in the local timezone. Using this option is not recommended for normal usage, as it is meant only for testing ISO output validity.

Todo

The following is a list of changes that will need to be made to the original source code and project in general:

  • the program doesn't support MPEG-4 ASP, even though MPEG-4 ASP is defined in the TS specification
  • no Opus audio support
  • several muxing bugs when muxing a HEVC/UHD stream - results in an out-of-sync stream
  • has issues with 24-bit DTS Express
  • issues with the 3D plane lists when there are mismatches between the MPLS and M2TS

Contributing

We’re really happy to accept contributions from the community, that’s the main reason why we open-sourced it! There are many ways to contribute, even if you’re not a technical person.

We’re using the infamous simplified Github workflow to accept modifications (even internally), basically you’ll have to:

  • create an issue related to the problem you want to fix (good for traceability and cross-reference)
  • fork the repository
  • create a branch (optionally with the reference to the issue in the name)
  • hack hack hack
  • commit incrementally with readable and detailed commit messages
  • submit a pull-request against the master branch of this repository

We’ll take care of tagging your issue with the appropriated labels and answer within a week (hopefully less!) to the problem you encounter.

If you’re not familiar with open-source workflows or our set of technologies, do not hesitate to ask for help! We can mentor you or propose good first bugs (as labeled in our issues). Also welcome to add your name to Credits section of this document.

All pull requests must pass code style checks which are executed with

clang-format
version 9. Therefore, it is advised to install an appropriate commit hook (for example this one) to your local repository in order to commit properly formatted code right away.

Submitting Bugs

You can report issues directly on Github, that would be a really useful contribution given that we lack some user testing on the project. Please document as much as possible the steps to reproduce your problem (even better with screenshots).

Building

For full details on building tsMuxer for your platform please see the document on COMPILING.

Testing

In absence of a full test suite currently we are creating some basic tests that can be performed.

The first test is a simple MKV to M2TS test with the first 2 minutes of Big Buck Bunny.

You need the file bbb-2mins.mkv and to either use the M2TS option in tsMuxerGUI or use the following meta file:

MUXOPT --no-pcr-on-video-pid --new-audio-pes --vbr  --vbv-len=500
V_MPEG-2, "bbb-2mins.mkv", track=1, lang=und
A_AC3, "bbb-2mins.mkv", track=2, lang=und

The MD5 sums of the original file and the output file should be:

a239a724cba1381a5956b50cb8b46754  bbb-2mins.mkv
62342b056d37e44fae4e48161d6208bf  bbb-2mins-from-linux-meta.m2ts

We will have also done the same with the test file Life Untouched. Results of the MD5 sums for the original and output file are below:

f2db8f6647f4f2a0b2417aed296fee73  Life Untouched 4K Demo.mp4
aba9ee3a3211cd09ba4833a610faff22  Life Untouched 4K Demo.m2ts

We need more sample files with 3D and multiple subtitle tracks if possible so if you have any ways of testing these files (particularly in relation to the bugs in the TODO section) please let us know?

Financing

We are not currently accepting any kind of donations and we do not have a bounty program.

Versioning

Version numbering follows the Semantic versioning approach.

License

We’re using the Apache 2.0 license for simplicity and flexibility. You are free to use it in your own project.
