MediaPipe (old) News

MediaPipe 0.8.7 has been released! We haven't played much with the core, this update mainly fixes and adds a few pipes to our collection. Things of interest:

• The MPEGEncoder pipe, based on the mjpeg mpeg2enc has been optimized for G4 (thanks to James Klicman who did an incredible job) and the pipe is now at least 3 times faster for those with an AltiVec unit!
• New MPipes have appeared, based on ffmpeg:
  • MSMPEG4Encoder - v1, v2 and v3 (DivX)
  • OpenDivXEncoder
  • AviMuxer
  • AsfMuxer
• Other neat MPipes were written:
  • AAC Encoder, based on faac
  • QTAudioDecoder which decodes anything that QuickTime supports
  • AudioResampler to change the sample rate of audio
  • ColorLut uses a look-up table to change the video gamma/gain, and white and black points
• Some utilities are now bundled with MediaPipe:
  • AAC to MP4, since QuickTime doesn't read raw aac files
  • MpegMoreInfo X, to know more about your input/output mpeg

MediaPipe 0.8.5 has been released! Here is a list of some improvements:

• Pipeline can be saved and loaded. The files format is the same for both the CLI and the GUI front end - so you can edit a pipeline graphically, save it, and load it from the command-line tool for example. The file format is in XML using Daniel Veillard's libxml.
• Pipes remember their last settings (does not apply to the CLI)
• Some sort of "inspector" has been implemented. It is not complete, but it gives you an idea of things to come. The inspector allows you to view the output of the selected pipe in a pipeline, giving you a quick way to see what's going on.
• The MPEG demuxer can now output AC3, which means you can now go directly from a vob to AIFF, MP3, MP2 or Ogg Vorbis. I rewrote the demuxer myself from scratch, so the code has not been heavily tested and I took no shortcut... It will get faster in the next release when I'm sure it actually works!
• The UI has been improved, mainly you can view and edit the settings of the pipes directly on the pipeline.
• The application will now check automatically for newer versions (this option can be disabled from the preferences)

It's been a while, I know... Here is MediaPipe 0.8 though. For some of you, 0.8 will not look as good as 0.7.6 (and you might want to stick with 0.7.6 in some cases) - the pipes do no remember their last settings and some other features were temporarily dropped. However, the core has been fully rearchitectured, the SDK uses opaque structures and the API is much more mature. MediaPipe 0.8 is a new generation of MediaPipe and all the work I've been doing on MediaPipe for the last two months will show better in future releases.

The SDK for MediaPipe 0.8 is also online and can be downloaded. Note that the documentation has mysteriously disappeared so until I rewrite it, your best guide is the online code and the developer mailing list.

I will try to spend some time in the following days to update the web site with tutorials and more info on MediaPipe 0.8 (and how cool it is ;-) )

MediaPipe 0.7.6 was released. Features improved support for MPEG encoding, a (slow) deinterlacer and some minor bug fixes

MediaPipe 0.7.5 was released. The MPPipes now remember their settings, and you can save and open pipelines.

Some of the MPPipes released in today's package are broken (I did not compile/test them properly, sorry about that). I released MediaPipe0.7r2, which includes the fixed MPPipes.

• MediaPipe 0.7 was released
• The MediaPipe SDK 0.7 was released
• The MediaPipe Library 0.7 was released
• The MediaPipe Library API 0.7 was released

• I am about to release MediaPipe 0.7 and I am currently reorganizing the web site... meanwhile it will probably be going up and down =)

• Release of MediaPipe 0.6. Fixes and some minor conceptual changes. Comes with TCP Pipes (thanks to Benad) enabling distributed computing over LANs and opening possibilities for streaming solutions.
• Posted the MediaPipe 0.6 SDK.
• The open source part of the project is now on SourceForge. You can thus get the latest pipes and SDK from there.

• Release of MediaPipe 0.5.5. Mainly bug fixes and minor clean up in the SDK. I also added an OggVorbis audio encoder. For the Ogg Vorbis Encoder pipe to load, make sure you move the proper frameworks in your Library/Frameworks folder. QuickTime support for Ogg Vorbis is also available here.
• Posted the MediaPipe 0.5.5 SDK.

• Release of MediaPipe 0.5.0. Changes include better error messages (for developers), detection of valid pipe for pipeline construction (invalid pipes cannot be added to the pipeline) and ability to save settings of pipes (though not supported by any pipe yet) and pipelines.

  This version is probably easier to use since it will not let you build invalid pipelines, but it does not react very well when you cancel the configuration of a pipe when adding to a pipeline...

• Posted the MediaPipe 0.5.0 SDK .

• I released the source code for the MPEG2Decoder and the VOBDemuxer. Both are released under GPL. I will post the source code of more pipes soon.

• Added a tutorial to write MPPipes with Project Builder. Alternatively, you can still read the tutorial to write MPPipes with CodeWarrior.

• Some pipes, like the MPEG2 Decoder, the VOB Demuxer and the AC-3 Decoder are GPLed because they use FFmpeg. I will release the source code for those within a week (send me an email if you need it right away).
• The MP3 Encoder has been removed from MediaPipe because it was violating patents for MP3 encoding. I am trying to see if I could at least release the source code for it. Until then, no MP3 encoding with MediaPipe.

• Released MediaPipe 0.3.5
  • Added support for Bundle MPPipes (thus making it possible to write MPPipes with Project Builder
  • Added error messages and fixes some bugs
  • Updated the SDK to compile with Project Builder
  • Updated the SISO pipe tutorial to work with 0.3.5

• First public release
