Finally there is the shiny new version of the mjpegtools, called 2.0.0 release.

There are updates and patches for a lot of programs so they work with newer libs and programs.
mpeg2enc, y4mdenoise and yuvdenoise did get some bigger updates, along with a lot of smaller updates for the other programs.

MJPEGTools 2.0.0rc1 released

2010-12-31T11:26:43Z

Here is our shiny new version of the mjpegtools. About 2 years have passed since the last release. This is the first Release Candidate of the mjpegtools. Depending on the number of changes there might be another ReleaseCandidates.
The next release will be the 2.0.0 because the mjpegtools are already 10 year on Sourceforge, and we start into our 2nd decade, and so the Major release number was chosen.

So download and test the mjpegtools 2.0.0.rc1

MJPEGTools 1.9.0 released

We have just released the 1.9.0 rc4 which will become the 1.9.0, if we don't find any bugs. If you find an bug/problem please report it to the mjpeg-users mailinglist.
The major improvment compared with the RC3 is that a rate control bug in mpeg2enc is fixed.
Beside the Linux packages we also have a precompiled windows package.

MJPEGTools 1.9.0rc3 released

MJPEGTools 1.8 released !

2005-09-26T04:26:12Z

Dear all,

after almost one-and-a-half-year, the drums thrill again, and as the
music plays, we hear the orcs coming in at the horizon. Oh, wait, eh,
that's another game.

!!! mjpegtools-1.8.0 is released !!!

Mjpegtools 1.8.0 brings you your favourite video/DVD processing tools,
which can be used for tons of purposes, such as digitizing your VHS
collection, creating and transcoding DVDs, doing advanced video
filtering on already-digitized videos (think denoising, unsharping,
deinterlacing, telekine, scaling, etc.), and many, many more things.
Mjpegtools is a complete suite of tools for you to capture, edit,
process, filter and play your media as you wish.

To download mjpegtools, you can go to our SourceForge project page
(http://www.sourceforge.net/projects/mjpeg/), where you'll find
tarballs, source/binary RPMs (for Fedora Core 4) and all our online
documentation, discussion fora and so on.

Here's a random list of changes that you'll find compared to the
previous release (1.6.2):

- changes in YUV4MPEG2 API to offer support for multiple colorspaces
(particularly useful for DV video), so that multiple planar YUV formats
(also monochrome or alpha) are supported.
- most filtering tools have been adapted to support multiple YUV formats,
so that you will not lose quality/precision in conversion steps.
- Many new or dramatically improved filters including (but not limited to):
*) yuvdenoise (denoising filter)
*) yuvdeinterlace (intelligent deinterlacing program)
*) y4munsharp (unsharp mask image sharpening program)
- Improvements in the IDCT/DCT routines in the MPEG-1/-2 encoder
(much more exact now and not subject to overflow/truncation on the
IA32 arch).
- MANY new utilties for importing/exporting data:
*) New and improved PGM/PNM conversion programs for dealing
with PPM data.
*) Utilities to convert raw (headerless) YUV data to and from
YUV4MPEG2 format. Useful when interfacing with other program
suites.
*) Program (yuyvtoy4m) to convert 4:2:2 data from digital cameras
into YUV4MPEG2 format for use with mjpegtools.
*) y4mstabilizer for stabilizing images with unsteady camera work
- Improvements and fixes in 'mplex' for handling PCM audio (LPCM
audio actually works now ;))
- DPME (Dual Prime Motion Estimation) in the encoder (mpeg2enc)
is fully functional (it was present but buggy/artifacted in the earlier
releases)
- Rate control in the encoder improved considerably.
- Much better Quicktime file handling (via libquicktime) especially
the audio tracks.
- Besides the always-excellent x86 support, we now have full support for
AMD64 (including MMX/SSE/etc. optimizations) and for PPC (e.g. Linux or
OS/X), and win32 support is also available (via Cygwin/Mingw).

Currently, there's one known bug: the MPEG encoder will not always work
correctly when used in multi-threading mode, and therefore the use of
the -M option with a number different than zero is not recommended. This
is not a large problem, since nowadays, filters take far more CPU than
the actual MPEG encoding, and the kernel will take care of separating
the different filtering processes over your multiple CPUs (if you have
any).
There may be more bugs, even after this long time of testing. Therefore,
if you see any, please report it to the mailinglist / developers so we
can fix them (mjpeg-users@lists.sf.net).

As a final note, I'd like to drop a small personal message. I've lead
the release management of mjpegtools for several years, and because of
changes in personal life (start of a PhD program in Manhattan, limited
time, new social life, etc.), I've decided to step down as release
manager. Steven, who has been very active in pretty much all areas of
mjpegtools, has accepted the honour of being our new release manager.
Steven, thanks and good luck! Also a big thanks to all contributors to
this release, mjpegtools would not exist without you!

Enjoy!

Ronald

mjpegtools 1.6.2 released

The development team is proud to announce version 1.6.2 of your favourite video and DVD capture, filtering and encoding toolset. Mjpeg tools is a suite of programs which support video capture, editting, playback, and compression to MPEG of MJPEG video. Edit, play and compression software is hardware independent. Capture supports MJPEG hardware (Buz, Miro DC10+ etc).

1.6.0 released!

2002-05-06T10:58:34Z

After a year of hard work, the mjpeg project group is proud to announce the availability of mjpegtools-1.6.0! This release contains a huge list of updates over 1.4.1, including video4linux-recording support for generic (non-mjpeg) video4linux devices, the availability of libraries for several functions (opening files, encoding/decoding JPEG frames, etc.), a fully rewritten DVD/(S)VCD-capable MPEG multiplexer and the best MPEG-encoder available for free. We also include several completely new tools, such as a video-scaler, a video-denoiser, a video-3:2 pulldown convertor and many more filters. Also included are a divx-encoder and -decoder. A mpeg-decoder is available separately to make full use of our filters when transcoding your movies.
