- - QCustomPlot for the histogram display in the frame analyzer.

- libmicrohttpd for the embedded web server.

- libjpeg, for encoding MJPEG streams when VA-API JPEG support is not
available.

+Exceptions as of July 2022:
- Debian does not carry CEF (but it is optional). You can get experimental
(and not security-supported) CEF Debian packages built for unstable at
meson obj -Dcef_dir=/usr/lib/x86_64-linux-gnu/cef -Dcef_build_type=system -Dcef_no_icudtl=true
- - You will need bmusb from testing or unstable; buster only has 0.7.3.
- Or, if you're using a git checkout, you can use a submodule:
-
- git submodule init
- git submodule update
- meson obj -Dembedded_bmusb=true
+ - Debian's SVT-AV1 is too old, so you will need to compile it yourself
+ if you wish to use it for streaming.
