1 Nageru 1.4.0, October ??, 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.
11 - Support for having MIDI controllers control various aspects of the
12 audio UI, with relatively flexible mapping. Note that different
13 MIDI controllers can vary significantly in what protocol they speak,
14 so Nageru will not necessarily work with all. (The primary testing
15 controller has been the Akai MIDImix, and a pre-made mapping for
16 that is included. The Korg nanoKONTROL2 has also been tested and
17 works, but it requires some Korg-specific SysEx commands to make
18 the buttons and lights work.)
20 - Add a disk space indicator to the main window.
22 - Various bugfixes. In particular, an issue where the audio would pitch
23 up sharply after a series of many dropped frames has been fixed.
26 Nageru 1.3.4, August 2nd, 2016
31 Nageru 1.3.3, July 27th, 2016
33 - Various changes to make distribution packaging easier; in particular,
34 theme data can be picked up from /usr/local/share/nageru.
36 - Fix various FFmpeg deprecation warnings, now that we need FFmpeg
37 3.1 for other reasons anyway.
40 Nageru 1.3.2, July 23rd, 2016
42 - Allow limited hotplugging (unplugging and replugging) of USB cards.
43 You can use the new command-line option --num-fake-cards (-C) to add
44 fake cards that show only a single color and that will be replaced
45 by real cards as you plug them in; you can also unplug cards and have
46 them be replaced by fake cards. Fake cards can also be used for testing
47 Nageru without actually having any video cards available.
49 - Add Metacube timestamping of every keyframe, for easier detection of
50 streams not keeping up. Works with the new timestamp feature of
51 Cubemap 1.3.1. Will be ignored (save for some logging) in older
54 - The included default theme has been reworked and cleaned up to be
55 more understandable and extensible.
57 - Add more command-line options for initial audio setup.
60 Nageru 1.3.1, July 1st, 2016
62 - Various display bugfixes.
65 Nageru 1.3.0, June 26th, 2016
67 - It is now possible, given enough CPU power (e.g., a quad-core Haswell or
68 faster desktop CPU), to output a stream that is suitable for streaming
69 directly to end users without further transcoding. In particular, this
70 includes support for encoding the network stream with x264 (the stream
71 saved to disk is still done using Quick Sync), for Metacube framing (for
72 streaming to the Cubemap reflector), and for choosing the network stream
73 mux. For more information, see the README.
75 - Add a flag (--disable-alsa-output) to disable ALSA monitoring output.
77 - Do texture uploads from the main thread instead of from separate threads;
78 may or may not improve stability with NVIDIA's proprietary drivers.
80 - When beginning a new video segment, the shutdown of the old encoder
81 is now done in a background thread, in order to not disturb the external
82 stream. The audio still goes into a somewhat random stream, though.
84 - You can now override the default stream-to-card mapping with --map-signal=
87 - Nageru now tries to lock itself into RAM if it has the permissions to do
88 so, for better realtime behavior. (Writing the stream to disk tends to
89 fill the buffer cache, eventually paging less-used parts of Nageru out.)
91 - Various fixes for deadlocks, memory leaks, and many other errors.
94 Nageru 1.2.1, April 15th, 2016
96 - Images are now updated from disk about every second, so that it is possible
97 to update e.g. overlays during streaming, although somewhat slowly.
99 - Fix support for PNG images.
101 - You can now send SIGHUP to start a new cut instead of using the menu.
103 - Added a --help option.
105 - Various tweaks to OpenGL fence handling.
108 Nageru 1.2.0, April 6th, 2016
110 - Support for Blackmagic's PCI and Thunderbolt cards, using the official
111 (closed-source) Blackmagic drivers. (You do not need the SDK installed, though.)
112 You can use PCI and USB cards pretty much interchangeably.
114 - Much more stable handling of frame queues on non-master cards. In particular,
115 you can have a master card on 50 Hz and another card on 60 Hz without getting
116 lots of warning messages and a 10+ frame latency on the second card.
118 - Many new options in the right click menu on cards: Adjustable video inputs,
119 adjustable audio inputs, adjustable resolutions, ability to select card for
122 - Add support for starting with almost all audio processing turned off
125 - The UI now marks inputs with red or green to mark them as participating in
126 the live or preview signal, respectively. Red takes priority. (Actually,
127 it merely asks the theme for a color for each input; the theme contains
130 - Add support for uncompressed video instead of H.264 on the HTTP server,
131 while still storing H.264 to files (--http-uncompressed-video). Note that
132 depending on your client, this might not actually be more CPU efficient
133 even on localhost, so be sure to check.
135 - Add a simpler, less featureful theme (simple.lua) that should be easier to
136 understand for beginners. Themes are now also choosable with -t on the command
139 - Too many bugfixes and small tweaks to list. In particular, many memory leaks
140 in the streaming part have been identified and fixed.
143 Nageru 1.1.0, February 24th, 2016
145 - Support doing the H.264 encoding on a different graphics device from the one
146 doing the mixing. In particular, this makes it possible to use Nageru on an
147 NVIDIA GPU while still encoding H.264 video using Intel Quick Sync (NVENC
148 is not supported yet) -- it is less efficient since the data needs to be read
149 back via the CPU, but the NVIDIA cards and drivers are so much faster that it
150 doesn't really matter. Tested on a GTX 950 with the proprietary drivers.
152 - In the included example theme, fix fading to/from deinterlaced sources.
154 - Various smaller compilation, distribution and documentation fixes.
