* High output quality; Lanczos3 scaling, subpixel precision everywhere,
white balance adjustment, mix of 16- and 32-bit floating point
- for intermediate calculations, dithered output.
+ for intermediate calculations, dithered output, optional 10-bit input
+ and output support.
* 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.
+
- libmicrohttpd for the embedded web server.
- x264 for encoding high-quality video suitable for streaming to end users.
- 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.
+ 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.
- libpci, for printing friendly PCI device names in an error message.
+ - 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
+
+ Simply download the right build for your platform (the “minimal” build
+ is fine) and add CEF_DIR=<path>/cef_binary_X.XXXX.XXXX.XXXXXXXX_linux64
+ on the make command line (substituting X with the real version as required).

If on Debian stretch 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
+ apt install qtbase5-dev libqt5opengl5-dev qt5-default libqcustomplot-dev \
+ pkg-config libmicrohttpd-dev libusb-1.0-0-dev libluajit-5.1-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 February 2018:
+
+ - You will need Movit from unstable; stretch only has 1.4.0.
+
+ - You will need bmusb from unstable; stretch only has 0.5.4.
-Exceptions as of November 2016:
+ - Debian does not carry CEF (but it is optional).
- - 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.
