1 Nageru 1.5.0, April 5th, 2017
3 - Support for low-latency HDMI/SDI output in addition to (or instead of) the
4 stream. This currently only works with DeckLink cards, not bmusb. See the
5 manual for more information.
7 - Support changing the resolution from the command line, instead of locking
8 everything to 1280x720.
10 - The A/V sync code has been rewritten to be more in line with Fons
11 Adriaensen's original paper. It handles several cases much better,
12 in particular when trying to match 59.94 and 60 Hz sources to each other.
13 However, it might occasionally need a few extra seconds on startup to
14 lock properly if startup is slow.
16 - Add support for using x264 for the disk recording. This makes it possible,
17 among other things, to run Nageru on a machine entirely without VA-API
20 - Support for 10-bit Y'CbCr, both on input and output. (Output requires
21 x264 disk recording, as Quick Sync Video does not support 10-bit H.264.)
22 This requires compute shader support, and is in general a little bit
23 slower on input and output, due to the extra amount of data being shuffled
24 around. Intermediate precision is 16-bit floating-point or better,
27 - Enable input mode autodetection for DeckLink cards that support it.
28 (bmusb mode has always been autodetected.)
30 - Add functionality to add a time code to the stream; useful for debugging
33 - The live display is now both more performant and of higher image quality.
35 - Fix a long-standing issue where the preview displays would be too bright
36 when using an NVIDIA GPU. (This did not affect the finished stream.)
38 - Many other bugfixes and small improvements.
41 Nageru 1.4.2, November 24th, 2016
43 - Fix a thread race that would sometimes cause x264 streaming to go awry.
46 Nageru 1.4.1, November 6th, 2016
51 Nageru 1.4.0, October 26th, 2016
53 - Support for multichannel (or more accurately, multi-bus) audio,
54 choosable from the UI or using the --multichannel command-line
55 flag. In multichannel mode, you can take in inputs from multiple
56 different sources (or different channels on the same source, for
57 multichannel sound cards), apply effects to them separately and then
58 mix them together. This includes both audio from the video cards
59 as well as ALSA inputs, including hotplug. Ola Gundelsby contributed
60 invaluable feedback on this feature throughout the entire
63 - Support for having MIDI controllers control various aspects of the
64 audio UI, with relatively flexible mapping. Note that different
65 MIDI controllers can vary significantly in what protocol they speak,
66 so Nageru will not necessarily work with all. (The primary testing
67 controller has been the Akai MIDImix, and a pre-made mapping for
68 that is included. The Korg nanoKONTROL2 has also been tested and
69 works, but it requires some Korg-specific SysEx commands to make
70 the buttons and lights work.)
72 - Add a disk space indicator to the main window.
74 - Various bugfixes. In particular, an issue where the audio would pitch
75 up sharply after a series of many dropped frames has been fixed.
78 Nageru 1.3.4, August 2nd, 2016
83 Nageru 1.3.3, July 27th, 2016
85 - Various changes to make distribution packaging easier; in particular,
86 theme data can be picked up from /usr/local/share/nageru.
88 - Fix various FFmpeg deprecation warnings, now that we need FFmpeg
89 3.1 for other reasons anyway.
92 Nageru 1.3.2, July 23rd, 2016
94 - Allow limited hotplugging (unplugging and replugging) of USB cards.
95 You can use the new command-line option --num-fake-cards (-C) to add
96 fake cards that show only a single color and that will be replaced
97 by real cards as you plug them in; you can also unplug cards and have
98 them be replaced by fake cards. Fake cards can also be used for testing
99 Nageru without actually having any video cards available.
101 - Add Metacube timestamping of every keyframe, for easier detection of
102 streams not keeping up. Works with the new timestamp feature of
103 Cubemap 1.3.1. Will be ignored (save for some logging) in older
106 - The included default theme has been reworked and cleaned up to be
107 more understandable and extensible.
109 - Add more command-line options for initial audio setup.
112 Nageru 1.3.1, July 1st, 2016
114 - Various display bugfixes.
117 Nageru 1.3.0, June 26th, 2016
119 - It is now possible, given enough CPU power (e.g., a quad-core Haswell or
120 faster desktop CPU), to output a stream that is suitable for streaming
121 directly to end users without further transcoding. In particular, this
122 includes support for encoding the network stream with x264 (the stream
123 saved to disk is still done using Quick Sync), for Metacube framing (for
124 streaming to the Cubemap reflector), and for choosing the network stream
125 mux. For more information, see the README.
127 - Add a flag (--disable-alsa-output) to disable ALSA monitoring output.
129 - Do texture uploads from the main thread instead of from separate threads;
130 may or may not improve stability with NVIDIA's proprietary drivers.
132 - When beginning a new video segment, the shutdown of the old encoder
133 is now done in a background thread, in order to not disturb the external
134 stream. The audio still goes into a somewhat random stream, though.
136 - You can now override the default stream-to-card mapping with --map-signal=
139 - Nageru now tries to lock itself into RAM if it has the permissions to do
140 so, for better realtime behavior. (Writing the stream to disk tends to
141 fill the buffer cache, eventually paging less-used parts of Nageru out.)
143 - Various fixes for deadlocks, memory leaks, and many other errors.
146 Nageru 1.2.1, April 15th, 2016
148 - Images are now updated from disk about every second, so that it is possible
149 to update e.g. overlays during streaming, although somewhat slowly.
151 - Fix support for PNG images.
153 - You can now send SIGHUP to start a new cut instead of using the menu.
155 - Added a --help option.
157 - Various tweaks to OpenGL fence handling.
160 Nageru 1.2.0, April 6th, 2016
162 - Support for Blackmagic's PCI and Thunderbolt cards, using the official
163 (closed-source) Blackmagic drivers. (You do not need the SDK installed, though.)
164 You can use PCI and USB cards pretty much interchangeably.
166 - Much more stable handling of frame queues on non-master cards. In particular,
167 you can have a master card on 50 Hz and another card on 60 Hz without getting
168 lots of warning messages and a 10+ frame latency on the second card.
170 - Many new options in the right click menu on cards: Adjustable video inputs,
171 adjustable audio inputs, adjustable resolutions, ability to select card for
174 - Add support for starting with almost all audio processing turned off
177 - The UI now marks inputs with red or green to mark them as participating in
178 the live or preview signal, respectively. Red takes priority. (Actually,
179 it merely asks the theme for a color for each input; the theme contains
182 - Add support for uncompressed video instead of H.264 on the HTTP server,
183 while still storing H.264 to files (--http-uncompressed-video). Note that
184 depending on your client, this might not actually be more CPU efficient
185 even on localhost, so be sure to check.
187 - Add a simpler, less featureful theme (simple.lua) that should be easier to
188 understand for beginners. Themes are now also choosable with -t on the command
191 - Too many bugfixes and small tweaks to list. In particular, many memory leaks
192 in the streaming part have been identified and fixed.
195 Nageru 1.1.0, February 24th, 2016
197 - Support doing the H.264 encoding on a different graphics device from the one
198 doing the mixing. In particular, this makes it possible to use Nageru on an
199 NVIDIA GPU while still encoding H.264 video using Intel Quick Sync (NVENC
200 is not supported yet) -- it is less efficient since the data needs to be read
201 back via the CPU, but the NVIDIA cards and drivers are so much faster that it
202 doesn't really matter. Tested on a GTX 950 with the proprietary drivers.
204 - In the included example theme, fix fading to/from deinterlaced sources.
206 - Various smaller compilation, distribution and documentation fixes.
