Explicitly require features that are already present in the builds
(tenative, some may be removed, but just to ensure that features that
should be present get not removed by accident).
see failed run https://github.com/CESNET/UltraGrid/actions/runs/3657908562
See also 438dbfa4 - `aptitude build-dep` for whatever reason fails on GH
CI ON installation of debhelper-compat(=12), which is a virtual package
provided by debhelper, apt doesn't.
log:
+ sudo aptitude -y build-dep libsdl2-mixer libsdl2-ttf libsdl2-dev:
[...]
Building tag database...
Unable to apply some actions, aborting
Unable to satisfy the build-depends: Build-Depends: debhelper-compat (= 12)
So use it (the `cmake --install` is perhaps better than make install
since it doesn't trigger rebuilds so often). Also to be consistent with
the other SVT compressions.
It should not be necessary. The distro is quite bulky and it would
update things like PHP etc. and wastes relatively significant time
(approx. 15 minutes - bootstrap time was reduced from 20 to 5 mins).
Fixed a fail in U20.04 (currently GH's ubuntu-latest) affecting
coverity-scan (continuous still using 18.04):

A dependency of libsdl2 debhelper-compat=12 is not available. apt
frontend can handle that somehow, but aptitude doesn't, so use apt to
install SDL2 dependencies (aptitude still used for mixer and ttf to
avoid installation of libsdl2 library itself).
It seems like that changing arbitrary packages installed (dependencies
for SDL) cause some FFmpeg dependencies to be rebuild (libvpx, SVT-*).
So revert back to depending on whole .github/scripts/Linux/prepare.sh
but move building/installation of AJA, live555 etc. to separate file
to reduce cached FFmpeg rebuilds at least a bit.
+ removed chmod 777 /usr/local
The file with dependencies installation is a prerequisity for FFmpeg
rebuild so move it to a smaller file to reduce number of required FFmpeg
rebuilds if that file changes.
Install libopencv-core-dev instead of libopencv-dev because it
transitively (libopencv-highgui-dev) depend on libswscale-dev that is
going to be removed.
Patch is from https://github.com/RPi-Distro/ffmpeg
The newest patch for 4.3.4 doesn't compile on buster because of
undefined V4L2_CID_CODEC_STATELESS_BASE
- check appimage with Arch and --capabilities - this catches segfault
with incompatible jack implementation in bundle and system
(pipewire-jack package needed)
- use empty directory for container build (instead of ".") also for
Ubuntu (would not needlessly copy contents of current directory to
Docker daemon)
