mvcp-client improvements
Apr 18, 2011
If you are using Melted, then you will be interested in some improvements I made to mvcp-client that lets you run MVCP commands and exit immediately. This is very handy for use in shell scripts at/cron jobs. Also, you can use it to send XML to the server. After updating, run mvcp-client -h to get usage help.
encoding documentation
Apr 8, 2011
Often people want to know how to set encoding parameters for MLT. So, I improved the service metadata for the avformat producer and consumer by improving their existing metadata and extending them with AVOptions from the FFmpeg/libav libraries. The
result is on the MLT website.
This same information can be obtained from the command 'melt -query consumer=avformat'.
DeckLink enhancements
Apr 3, 2011
dorfTV, a community television station in Austria, has sponsored two enhancements to the decklink plugin. First is input support so you can capture and do live encoding. The second is support for keying, which makes the DeckLink hardware composite the MLT video output over live SDI video input with full alpha blending. You can get more information from the online help: melt -query producer=decklink or melt -query consumer=decklink.

build scripts
Mar 25, 2011
I have
published some scripts that can build and rebuild MLT, Melted, and Kdenlive and many of its multimedia dependencies (x264, libvpx, FFmpeg, frei0r). The script pulls the latest of each from their source code repositories on each build and rebuild. Each build is output to a dated folder without requiring any "system" installation, and the folder can be simply copied to other compatible machines and run again without any packaging or system installation.
