white balance adjustment, mix of 16- and 32-bit floating point
- for intermediate calculations, dithered output.

* Proper sound support: Syncing of multiple unrelated sources through
high-quality resampling, multichannel mixing with separate effects
pipelines, running transitions etc., so that the visual look is
consistent between operators.
+ * Comprehensive monitoring through Prometheus metrics.

.. [1] For reference, that is: Core i7 4600U (dualcore 2.10GHz, clocks down
to 800 MHz after 30 seconds due to thermal constraints), Intel HD Graphics
4400 (ie., without the extra L4 cache from Iris Pro), single-channel DDR3 RAM
usually give you a newer version). It currently need:
- Movit, my GPU-based video filter library (https://movit.sesse.net).
- You will need at least version 1.3.1, but at least 1.4.0 is recommended.
+ You will need at least version 1.5.2.
- Qt 5.5 or newer for the GUI.
+ - QCustomPlot for the histogram display in the frame analyzer
+ (no longer needed from Nageru 2.2.0).
+
- libmicrohttpd for the embedded web server.
- x264 for encoding high-quality video suitable for streaming to end users.
- - ffmpeg for muxing, and for encoding audio. You will need at least
- version 3.1.

+ version 5.0.
- Working OpenGL; Movit works with almost any modern OpenGL implementation.
- Nageru has been tested with Intel on Mesa (you want 11.2 or newer, due
- to critical stability bugfixes), and with NVIDIA's proprietary drivers.
- AMD's proprietary drivers (fglrx) are known not to work due to driver bugs;
- I am in contact with AMD to try to get this resolved.
+ Nageru has been tested with Intel on Mesa), and with NVIDIA's proprietary drivers.
+ The status of AMD's proprietary drivers is currently unknown.
- libzita-resampler, for resampling sound sources so that they are in sync
between sources, and also for oversampling for the peak meter.
- - Lua, for driving the theme engine.
+ - LuaJIT, for driving the theme engine. You will need at least version 2.1.
+
+ - libjpeg, for encoding MJPEG streams when VA-API JPEG support is not
+ available.
+
+ - Protocol Buffers (protobuf), for storing various forms of settings and
+ state.
+
+ - Meson, for building.
+
+ - Optional: CEF (Chromium Embedded Framework), for :doc:`HTML graphics <html>`.
+ If you build without CEF, the HTMLInput class will not be available from
+ the theme. You can get binary downloads of CEF from
+
+ http://opensource.spotify.com/cefbuilds/index.html
+
+ Download the right build for your platform (the “minimal” build
+ is fine) and add -Dcef_dir=<path>/cef_binary_X.XXXX.XXXX.XXXXXXXX_linux64
+ on the meson command line (substituting X with the real version as required).
+
+ - Optional: libsrt, for SRT inputs (by default, Nageru will listen on
+ port 9710, although you can change this port on the command line,
+ turn it off with --srt-port -1, or turn it off live in the UI).
+ SRT can also be used for output in addition to listening for HTTP
+ (see --srt-destination). If you build with libsrt, make sure it is not
+ linked to OpenSSL, for license reasons.
+
+ - Optional: SVT-AV1, for encoding high-quality video suitable for streaming to
+ end users (higher quality than using x264, but not nearly as mature).
+ You will need at least version 1.5.0.
- - libpci, for printing friendly PCI device names in an error message.
+:doc:`Futatabi <futatabi>` also needs:
-If on Debian stretch or something similar, you can install everything you need
+ - A fast GPU with OpenGL 4.5 support (GTX 1080 or similar recommended for
+ best quality at HD resolutions, although 950 should work).
+
+ - SQLite, for storing state.
+
+If on Debian bullseye or something similar, you can install everything you need
with:
- apt install qtbase5-dev libqt5opengl5-dev qt5-default pkg-config libmicrohttpd-dev \
- libusb-1.0-0-dev liblua5.2-dev libzita-resampler-dev libva-dev \
- libavcodec-dev libavformat-dev libswscale-dev libavresample-dev \
- libmovit-dev libegl1-mesa-dev libasound2-dev libx264-dev libbmusb-dev \
- protobuf-compiler libprotobuf-dev libpci-dev
-Exceptions as of November 2016:
+ apt install qtbase5-dev libqt5opengl5-dev qt5-default \
+ pkg-config libmicrohttpd-dev libusb-1.0-0-dev libluajit-5.1-dev \

+
+
+Exceptions as of September 2023:
+
+ - Debian does not carry CEF (but it is optional). You can get experimental
+ (and not security-supported) CEF Debian packages built for unstable at
+ http://storage.sesse.net/cef/, and then configure Nageru with
+
+ meson obj -Dcef_dir=/usr/lib/x86_64-linux-gnu/cef -Dcef_build_type=system -Dcef_no_icudtl=true
- - libusb 1.0.21 is not yet in stretch; you need to fetch it from sid.
- Same with a bmusb version built against it.
The patches/ directory contains a patch that helps zita-resampler performance.
It is meant for upstream, but was not in at the time Nageru was released.
It is taken to be by Steinar H. Gunderson <sesse@google.com> (ie., my ex-work
email), and under the same license as zita-resampler itself.
-To start it, just hook up your equipment, type “make” and then “./nageru”.
+Nageru and Futatabi use Meson to build. For a default build, type
+
+ meson obj && cd obj && ninja
+
+To start it, hook up your equipment, and then type “./nageru”.
