1 Nageru 1.4.0, October 26th, 2016
3 - Support for multichannel (or more accurately, multi-bus) audio,
4 choosable from the UI or using the --multichannel command-line
5 flag. In multichannel mode, you can take in inputs from multiple
6 different sources (or different channels on the same source, for
7 multichannel sound cards), apply effects to them separately and then
8 mix them together. This includes both audio from the video cards
9 as well as ALSA inputs, including hotplug. Ola Gundelsby contributed
10 invaluable feedback on this feature throughout the entire
13 - Support for having MIDI controllers control various aspects of the
14 audio UI, with relatively flexible mapping. Note that different
15 MIDI controllers can vary significantly in what protocol they speak,
16 so Nageru will not necessarily work with all. (The primary testing
17 controller has been the Akai MIDImix, and a pre-made mapping for
18 that is included. The Korg nanoKONTROL2 has also been tested and
19 works, but it requires some Korg-specific SysEx commands to make
20 the buttons and lights work.)
22 - Add a disk space indicator to the main window.
24 - Various bugfixes. In particular, an issue where the audio would pitch
25 up sharply after a series of many dropped frames has been fixed.
28 Nageru 1.3.4, August 2nd, 2016
33 Nageru 1.3.3, July 27th, 2016
35 - Various changes to make distribution packaging easier; in particular,
36 theme data can be picked up from /usr/local/share/nageru.
38 - Fix various FFmpeg deprecation warnings, now that we need FFmpeg
39 3.1 for other reasons anyway.
42 Nageru 1.3.2, July 23rd, 2016
44 - Allow limited hotplugging (unplugging and replugging) of USB cards.
45 You can use the new command-line option --num-fake-cards (-C) to add
46 fake cards that show only a single color and that will be replaced
47 by real cards as you plug them in; you can also unplug cards and have
48 them be replaced by fake cards. Fake cards can also be used for testing
49 Nageru without actually having any video cards available.
51 - Add Metacube timestamping of every keyframe, for easier detection of
52 streams not keeping up. Works with the new timestamp feature of
53 Cubemap 1.3.1. Will be ignored (save for some logging) in older
56 - The included default theme has been reworked and cleaned up to be
57 more understandable and extensible.
59 - Add more command-line options for initial audio setup.
62 Nageru 1.3.1, July 1st, 2016
64 - Various display bugfixes.
67 Nageru 1.3.0, June 26th, 2016
69 - It is now possible, given enough CPU power (e.g., a quad-core Haswell or
70 faster desktop CPU), to output a stream that is suitable for streaming
71 directly to end users without further transcoding. In particular, this
72 includes support for encoding the network stream with x264 (the stream
73 saved to disk is still done using Quick Sync), for Metacube framing (for
74 streaming to the Cubemap reflector), and for choosing the network stream
75 mux. For more information, see the README.
77 - Add a flag (--disable-alsa-output) to disable ALSA monitoring output.
79 - Do texture uploads from the main thread instead of from separate threads;
80 may or may not improve stability with NVIDIA's proprietary drivers.
82 - When beginning a new video segment, the shutdown of the old encoder
83 is now done in a background thread, in order to not disturb the external
84 stream. The audio still goes into a somewhat random stream, though.
86 - You can now override the default stream-to-card mapping with --map-signal=
89 - Nageru now tries to lock itself into RAM if it has the permissions to do
90 so, for better realtime behavior. (Writing the stream to disk tends to
91 fill the buffer cache, eventually paging less-used parts of Nageru out.)
93 - Various fixes for deadlocks, memory leaks, and many other errors.
96 Nageru 1.2.1, April 15th, 2016
98 - Images are now updated from disk about every second, so that it is possible
99 to update e.g. overlays during streaming, although somewhat slowly.
101 - Fix support for PNG images.
103 - You can now send SIGHUP to start a new cut instead of using the menu.
105 - Added a --help option.
107 - Various tweaks to OpenGL fence handling.
110 Nageru 1.2.0, April 6th, 2016
112 - Support for Blackmagic's PCI and Thunderbolt cards, using the official
113 (closed-source) Blackmagic drivers. (You do not need the SDK installed, though.)
114 You can use PCI and USB cards pretty much interchangeably.
116 - Much more stable handling of frame queues on non-master cards. In particular,
117 you can have a master card on 50 Hz and another card on 60 Hz without getting
118 lots of warning messages and a 10+ frame latency on the second card.
120 - Many new options in the right click menu on cards: Adjustable video inputs,
121 adjustable audio inputs, adjustable resolutions, ability to select card for
124 - Add support for starting with almost all audio processing turned off
127 - The UI now marks inputs with red or green to mark them as participating in
128 the live or preview signal, respectively. Red takes priority. (Actually,
129 it merely asks the theme for a color for each input; the theme contains
132 - Add support for uncompressed video instead of H.264 on the HTTP server,
133 while still storing H.264 to files (--http-uncompressed-video). Note that
134 depending on your client, this might not actually be more CPU efficient
135 even on localhost, so be sure to check.
137 - Add a simpler, less featureful theme (simple.lua) that should be easier to
138 understand for beginners. Themes are now also choosable with -t on the command
141 - Too many bugfixes and small tweaks to list. In particular, many memory leaks
142 in the streaming part have been identified and fixed.
145 Nageru 1.1.0, February 24th, 2016
147 - Support doing the H.264 encoding on a different graphics device from the one
148 doing the mixing. In particular, this makes it possible to use Nageru on an
149 NVIDIA GPU while still encoding H.264 video using Intel Quick Sync (NVENC
150 is not supported yet) -- it is less efficient since the data needs to be read
151 back via the CPU, but the NVIDIA cards and drivers are so much faster that it
152 doesn't really matter. Tested on a GTX 950 with the proprietary drivers.
154 - In the included example theme, fix fading to/from deinterlaced sources.
156 - Various smaller compilation, distribution and documentation fixes.
