Thanks to the sponsorship of BCE (Broadcast Centre Europe), the git version of the cbrts consumer now includes SMPTE 2022-2 RTP/UDP output. It has been successfully tested for 36 hours of continuous playback with an ateme DR8400 IRD and the DecTek StreamXpert performing PCR analysis and TR 101 290 monitoring.
In addition to the exciting new audio/visualization filters mentioned in the previous blog post, this version features some exciting API improvements for manipulating multitracks and property animations. There are still many services, however, that need updating to support animated properties. Also, since SourceForge is still recovering from a storage problem preventing the upload of new files, you can download the release source archive from GitHub.

MLT developer, Brian, developed 4 new filters, available now in git master. The fft filter uses the fast Fourier transform to produce data for other filters. The dance filter moves, scales, and rotates an image or video in reaction to the audio characteristics. The lightshow filter alters the color of the image based on the audio. Lastly, the audiowaveform filter draws a waveform over the image.
These were all sponsored by the "Learn Your Lyrics" YouTube channel. They generate the videos using MLT through shell scripts that generate long melt command lines. You can see the fft, dance, and audiowaveform filters in action in this video:
A major regression slipped into the 0.9.4 release plus some other good fixes rolled in just afer that release prompting this new release. Please discontinue using version 0.9.4 and upgrade.
