Windows Update

• Fix a few minor bugs preventing Video from running on Windows and Linux. We have now tested it on all three platforms.
• Initial work on live preview. The player has now been updated to show the video in the player window. Additionally Video can now seek video outputs (as well as inputs).

FFmpeg Alpha Update

This is an alpha version of Video v0.2. The main update here is dropping MLT as a dependency, and bundling FFmpeg for Windows and Mac builds. As such, Video can be used out of the box on now, without the need to hunt down the more obscure MLT library separately. Linux machines must still download the correct version of FFmpeg themselves. However, this is much easier to do.

Specifically, FFmpeg 3.2 is recommended, but the following specific library versions are also usable:

• libavcodec v57
• libavformat v57
• libavutil v55
• libswscale v4
• libswresample v2
• libavfilter v6

Again, these are included for the mac/windows builds, and are all part of an FFmpeg 3.x installation.

Some notes about why this is still alpha:

• The video preview currently does not work. People needing access to this feature need to use v0.1.1.
• Video has not been thoroughly tested

Once the first one has been addressed we can move to beta, and once both have been addressed we can move to rc.

MLT Compatibility Update

• Compatibility release for MLT. Development has shifted to the v0.2 line.
• Initial support for FFMPEG.

Paper Update

• Actually adds #lang and syntax for video.
• Adds minimal documentation, needs improvement.
• Add video-editor% widget for DrRacket.
• Build a proper rendering interface.
  • (No longer need to explicitly call out to MLT)
• Videos are converted to MLT object automatically.
• Added testing framework.
• Added language forms for writing documentation for Video.
• This was the release associated with the ICFP 2017 Paper: Super 8 Languages for Making Movies (DRAFT)

Initial Release

• First release of Video
• Depends on MLT (not included)
• API still very unstable
• No language yet, just video library.
• Must manually convert video object to MLT ones with convert-to-mlt!
• Preview player added.
