audio enhancements
May 16, 2011
Since the last release there have been four big enhancements in the area of audio:
- Reading files with more than 2 channels of greater than 16-bit audio - including floating point.
- Exposing each SoX effect as a separate audio filter making it possible to enumerate them and get metadata for them.
- Exposing each LADSPA plugin as a separate audio filter with metadata so you no longer need to use JACK Rack XML.
- Supporting JACK transport synchronization (melt -jack).
v0.7.2 released
May 2, 2011
This is a minor release to fix a few things between the 0.7.0 release and the release of Kdenlive 0.8. I recommend Kdenlive v0.8 users to upgrade to this version of Mlt. Beyond that there are some exciting additions to the Blackmagic Design DeckLink plugin!
Framework
- Added mlt_profile_list().
Modules
- Added decklink producer (i.e. capture, live encoding).
- Added keyer output for decklink consumer.
- Added AVOptions to the avformat service metadata.
- Added support for new major API versions (53) of FFmpeg.
Melt
- Added '-query profile' option.
- Added '-query formats', '-query audio_codecs' and '-query video_codecs'.
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.
