Release v2.0 · voc/voctomix

We are very pleased to announce the release of voctomix 2.0, the first release of a completely rewritten voctomix!

This version of voctomix requires atleast python 3.9!

Notable changes:

Source handling was reworked, so the past issues with sources slowly drifting over time should no longer appear.
Voctomix has switched away from the "preset" style mixer to a freely configurable video mixer. You can now freely choose sources for each mix.
- The missing presets feature has been noted in past events where we have run a prerelease version. Pull request #320 will re-add a tab to add presets to voctogui. It is expected to see this feature in voctomix 2.1
- The lecture mode has been configured to automatically crop the "A" source to the middle third to allow for a bigger image without compromising on the size of the "B" source.
Voctomix can now output the mixed video onto a gstreamer sink of your choice. See the documentation for details
Voctomix now supports a lot more input sources, including support for generic video4linux2 sources and the raspberry pi camera.
Voctomix can now utilize VAAPI to reduce the amount of CPU load by offloading graphics processing to a connected GPU.
- Please note that some consumer GPUs have limits on how many VAAPI encodings you can actually run on them. Voctomix runs a bunch of encodings in parallel, so you might run into issues there.
Voctomix can now display overlays onto a running mix. See the documentation for details

Audio issues when inputs have different frame (or sampling?) rates:
Users are advised to run all inputs that use audio on the same frame and sampling rate. This also includes the blinder source.
get_composite_modes control command does not work:
There is no workaround available.
voctomix assumes client is vaapi capable if vaapi is used on the server side:
There is no workaround available.
ControlServer does not broadcast preview changes:
There is no workaround available. Program changes get broadcasted correctly.
DPI scaling does not work:
If you need scaling, you can use the GDK_SCALE environment variable to scale the GUI. GDK_SCALE only supports integers though, so specifying 2 means the GUI elements are double the size.
