Pyqt5 and MLT compiled in OE

January 05, 2022 — BarryK

I have been looking around at video editors, as having ongoing issues with LiVES. There are a couple that require 'pyqt5' and at least one that requires 'mlt'. This is what I have compiled in OpenEmbedded:

fdk-aac          2.0.1
mlt              7.4.0
python3-pyqt5    5.15.1
qtquickcontrols2 5.14.2+gitAUTOINC+bb2b1adffe
sip3             4.19.23

MLT home page:

https://mltframework.org/

Here is my recipe, meta-quirky/recipes-support/mlt/mlt_7.4.0.bb:

So, what video-editors to consider? Have got a short list, will check them out.
