This is a test release of the new unstable series 2.17.x of DCP-o-matic, which includes everything in 2.16.80 and adds some new features and fixes.
You are advised to use this version only for testing, not in production systems.
- DCP-o-matic now takes video frame timing information from sources in a (hopefully) more reliable way, which should fix video/audio sync errors in a number of cases.
- Support has been added for a commercial (paid-for) GPU-based JPEG2000 encoder (‘Grok’) that provides dramatic encoding speed-ups with Nvidia graphics cards on Ubuntu 22.04.
- There is now experimental support for playback and creation of MPEG2 DCPs.
- The user interface for making VFs has changed. You can now set them up using a separate dialogue box, which can be opened with the ‘Version File (VF)...’ option in the ‘Tools’ menu.
- A new user interface for setting up reels has been added, which allows setup of custom reel breaks.
- UTC offset for KDMs is specified when KDMs are created, not when setting up the ‘Cinema’. This is to avoid difficulties when cinemas are in places where timezones change through the year (e.g. where there is daylight saving time).
- A separate DCP verification tool is included.
- DCP-o-matic can make text or HTML reports during verification runs.
- DCP-o-matic is now linked against openjpeg 2.5.2. This provides some worthwhile speed-ups compared to the previous version.
- DCP-o-matic is now linked against FFmpeg 6.1.
- The audio language settings has been moved to the DCP audio tab.
- On loading a project DCP-o-matic will show the DCP panel if that was what was open when the project was last edited.
- Some XML attribute names were reformatted to ‘camel-case’.
