newsLatest libcamera and pipewire compiled
I posted about a problem with meson version, and had to compile an older version of 'libcamera' in OpenEmbedded:
https://bkhome.org/news/202110/libcamera-compiled-in-openembedded.html
I had previously compiled meson 0.59.2 in OE, then rolled back to
0.53.0, however, I did keep the 0.59.2 binary package, and have made it
into a PET. That PET will be in the 'devx' SFS in the next release of
EasyOS.
With meson 0.59.2 in a running EasyOS, I was then able to compile the
latest 'libcamera' and 'pipewire'. I have done that, and made them into
PETs. They also will be in the next release of EasyOS.
Well probably, it depends how successful setting up pipewire is. I
have got it basically working, that will have to be the subject of a
later blog post.
For this post, documenting how I compiled libcamera and pipewire. Here are my notes, firstly, preliminary notes:
easyos 3.1.3
------------
20211031 after complete recompile in oe, with pulseaudio and pavucontrol.
easy 3.1.3:
apulse and bluez-alsa not in build-list.
pulseaudio and pavucontrol are in build-list.
downloaded tag 0.3.39 from here:
https://github.com/PipeWire/pipewire
requires meson >= 0.54.0
I had previously compiled meson 0.59.2, but in last recompile
rolled back to 0.53.2
install meson 0.59.2 binary tarball.
Now the notes on compiling libcamera:
libcamera 20211028
------------------
libcamera is optional dep
# git clone https://git.libcamera.org/libcamera/libcamera.git --depth 1
# mv libcamera libcamera-20211028
# dir2tgz libcamera-20211028
# cd libcamera-20211028
# meson build -Dprefix=/usr
# ninja -C build
# new2dir ninja -C build install
...hmmm, copy headers from /usr/include/libcamera/libcamera up-one
(otherwise breaks compile of pipewire).
This is the configuration of libcamera:
libcamera 0.0.0

Here are the notes on compiling pipewire:
pipewire 0.3.39
---------------
# meson setup builddir
internet connection required, as downloads 'media-session' package
# meson configure builddir -Dprefix=/usr -Dlibpulse=enabled -Dpipewire-jack=enabled -Dpipewire-v4l2=enabled -Dpipewire-alsa=enabled -Djack-devel=true
# ninja -C builddir
# cd builddir
# new2dir meson install
in target pet:
copy /usr/share/pipewire to /etc/
created /root/Startup/pipewire

Eventually, want to compile pipewire in OE. For future reference, a note on the likely dependencies:
dbus, sdl2, sndfile, libusb, libcap, webrtc, libnotify, alsa-lib, alsa-plugins,
bluez5, libv4l, libva, libx11, libasound, udev, ncurses, gstreamer
Notice further above, libcamera and pipewire are compiled without
'gstreamer', as don't currently have it in the running EasyOS. The focus
for now is on audio, but pipewire is also planned to be a management
daemon for video -- so sometime in the future might have to include
gstreamer as a dependency. Don't know about webrtc, just saw it
mentioned somewhere as a possible dependency.
