1 Nageru 1.4.2, November 24th, 2016
3 - Fix a thread race that would sometimes cause x264 streaming to go awry.
6 Nageru 1.4.1, November 6th, 2016
11 Nageru 1.4.0, October 26th, 2016
13 - Support for multichannel (or more accurately, multi-bus) audio,
14 choosable from the UI or using the --multichannel command-line
15 flag. In multichannel mode, you can take in inputs from multiple
16 different sources (or different channels on the same source, for
17 multichannel sound cards), apply effects to them separately and then
18 mix them together. This includes both audio from the video cards
19 as well as ALSA inputs, including hotplug. Ola Gundelsby contributed
20 invaluable feedback on this feature throughout the entire
23 - Support for having MIDI controllers control various aspects of the
24 audio UI, with relatively flexible mapping. Note that different
25 MIDI controllers can vary significantly in what protocol they speak,
26 so Nageru will not necessarily work with all. (The primary testing
27 controller has been the Akai MIDImix, and a pre-made mapping for
28 that is included. The Korg nanoKONTROL2 has also been tested and
29 works, but it requires some Korg-specific SysEx commands to make
30 the buttons and lights work.)
32 - Add a disk space indicator to the main window.
34 - Various bugfixes. In particular, an issue where the audio would pitch
35 up sharply after a series of many dropped frames has been fixed.
38 Nageru 1.3.4, August 2nd, 2016
43 Nageru 1.3.3, July 27th, 2016
45 - Various changes to make distribution packaging easier; in particular,
46 theme data can be picked up from /usr/local/share/nageru.
48 - Fix various FFmpeg deprecation warnings, now that we need FFmpeg
49 3.1 for other reasons anyway.
52 Nageru 1.3.2, July 23rd, 2016
54 - Allow limited hotplugging (unplugging and replugging) of USB cards.
55 You can use the new command-line option --num-fake-cards (-C) to add
56 fake cards that show only a single color and that will be replaced
57 by real cards as you plug them in; you can also unplug cards and have
58 them be replaced by fake cards. Fake cards can also be used for testing
59 Nageru without actually having any video cards available.
61 - Add Metacube timestamping of every keyframe, for easier detection of
62 streams not keeping up. Works with the new timestamp feature of
63 Cubemap 1.3.1. Will be ignored (save for some logging) in older
66 - The included default theme has been reworked and cleaned up to be
67 more understandable and extensible.
69 - Add more command-line options for initial audio setup.
72 Nageru 1.3.1, July 1st, 2016
74 - Various display bugfixes.
77 Nageru 1.3.0, June 26th, 2016
79 - It is now possible, given enough CPU power (e.g., a quad-core Haswell or
80 faster desktop CPU), to output a stream that is suitable for streaming
81 directly to end users without further transcoding. In particular, this
82 includes support for encoding the network stream with x264 (the stream
83 saved to disk is still done using Quick Sync), for Metacube framing (for
84 streaming to the Cubemap reflector), and for choosing the network stream
85 mux. For more information, see the README.
87 - Add a flag (--disable-alsa-output) to disable ALSA monitoring output.
89 - Do texture uploads from the main thread instead of from separate threads;
90 may or may not improve stability with NVIDIA's proprietary drivers.
92 - When beginning a new video segment, the shutdown of the old encoder
93 is now done in a background thread, in order to not disturb the external
94 stream. The audio still goes into a somewhat random stream, though.
96 - You can now override the default stream-to-card mapping with --map-signal=
99 - Nageru now tries to lock itself into RAM if it has the permissions to do
100 so, for better realtime behavior. (Writing the stream to disk tends to
101 fill the buffer cache, eventually paging less-used parts of Nageru out.)
103 - Various fixes for deadlocks, memory leaks, and many other errors.
106 Nageru 1.2.1, April 15th, 2016
108 - Images are now updated from disk about every second, so that it is possible
109 to update e.g. overlays during streaming, although somewhat slowly.
111 - Fix support for PNG images.
113 - You can now send SIGHUP to start a new cut instead of using the menu.
115 - Added a --help option.
117 - Various tweaks to OpenGL fence handling.
120 Nageru 1.2.0, April 6th, 2016
122 - Support for Blackmagic's PCI and Thunderbolt cards, using the official
123 (closed-source) Blackmagic drivers. (You do not need the SDK installed, though.)
124 You can use PCI and USB cards pretty much interchangeably.
126 - Much more stable handling of frame queues on non-master cards. In particular,
127 you can have a master card on 50 Hz and another card on 60 Hz without getting
128 lots of warning messages and a 10+ frame latency on the second card.
130 - Many new options in the right click menu on cards: Adjustable video inputs,
131 adjustable audio inputs, adjustable resolutions, ability to select card for
134 - Add support for starting with almost all audio processing turned off
137 - The UI now marks inputs with red or green to mark them as participating in
138 the live or preview signal, respectively. Red takes priority. (Actually,
139 it merely asks the theme for a color for each input; the theme contains
142 - Add support for uncompressed video instead of H.264 on the HTTP server,
143 while still storing H.264 to files (--http-uncompressed-video). Note that
144 depending on your client, this might not actually be more CPU efficient
145 even on localhost, so be sure to check.
147 - Add a simpler, less featureful theme (simple.lua) that should be easier to
148 understand for beginners. Themes are now also choosable with -t on the command
151 - Too many bugfixes and small tweaks to list. In particular, many memory leaks
152 in the streaming part have been identified and fixed.
155 Nageru 1.1.0, February 24th, 2016
157 - Support doing the H.264 encoding on a different graphics device from the one
158 doing the mixing. In particular, this makes it possible to use Nageru on an
159 NVIDIA GPU while still encoding H.264 video using Intel Quick Sync (NVENC
160 is not supported yet) -- it is less efficient since the data needs to be read
161 back via the CPU, but the NVIDIA cards and drivers are so much faster that it
162 doesn't really matter. Tested on a GTX 950 with the proprietary drivers.
164 - In the included example theme, fix fading to/from deinterlaced sources.
166 - Various smaller compilation, distribution and documentation fixes.
