1 Nageru 1.6.0, May 29th, 2017
3 - Add support for having videos (from file or from URL) as a separate
4 input channels, albeit with some limitations. Apart from the obvious use of
5 looping pause clips or similar, this can be used to integrate with CasparCG;
6 see the manual for more details.
8 - Add a frame analyzer (accessible from the Video menu) containing an
9 RGB histogram and a color dropped tool. This is useful in calibrating
10 video chains by playing back a known signal. Note that this adds a
11 dependency on QCustomPlot.
13 - Allow overriding Y'CbCr input interpretation, for inputs that don't
14 use the correct settings. Also, Rec. 601 is now used by default instead
15 of Rec. 709 for SD resolutions.
17 - Support other sample rates than 48000 Hz from bmusb.
20 Nageru 1.5.0, April 5th, 2017
22 - Support for low-latency HDMI/SDI output in addition to (or instead of) the
23 stream. This currently only works with DeckLink cards, not bmusb. See the
24 manual for more information.
26 - Support changing the resolution from the command line, instead of locking
27 everything to 1280x720.
29 - The A/V sync code has been rewritten to be more in line with Fons
30 Adriaensen's original paper. It handles several cases much better,
31 in particular when trying to match 59.94 and 60 Hz sources to each other.
32 However, it might occasionally need a few extra seconds on startup to
33 lock properly if startup is slow.
35 - Add support for using x264 for the disk recording. This makes it possible,
36 among other things, to run Nageru on a machine entirely without VA-API
39 - Support for 10-bit Y'CbCr, both on input and output. (Output requires
40 x264 disk recording, as Quick Sync Video does not support 10-bit H.264.)
41 This requires compute shader support, and is in general a little bit
42 slower on input and output, due to the extra amount of data being shuffled
43 around. Intermediate precision is 16-bit floating-point or better,
46 - Enable input mode autodetection for DeckLink cards that support it.
47 (bmusb mode has always been autodetected.)
49 - Add functionality to add a time code to the stream; useful for debugging
52 - The live display is now both more performant and of higher image quality.
54 - Fix a long-standing issue where the preview displays would be too bright
55 when using an NVIDIA GPU. (This did not affect the finished stream.)
57 - Many other bugfixes and small improvements.
60 Nageru 1.4.2, November 24th, 2016
62 - Fix a thread race that would sometimes cause x264 streaming to go awry.
65 Nageru 1.4.1, November 6th, 2016
70 Nageru 1.4.0, October 26th, 2016
72 - Support for multichannel (or more accurately, multi-bus) audio,
73 choosable from the UI or using the --multichannel command-line
74 flag. In multichannel mode, you can take in inputs from multiple
75 different sources (or different channels on the same source, for
76 multichannel sound cards), apply effects to them separately and then
77 mix them together. This includes both audio from the video cards
78 as well as ALSA inputs, including hotplug. Ola Gundelsby contributed
79 invaluable feedback on this feature throughout the entire
82 - Support for having MIDI controllers control various aspects of the
83 audio UI, with relatively flexible mapping. Note that different
84 MIDI controllers can vary significantly in what protocol they speak,
85 so Nageru will not necessarily work with all. (The primary testing
86 controller has been the Akai MIDImix, and a pre-made mapping for
87 that is included. The Korg nanoKONTROL2 has also been tested and
88 works, but it requires some Korg-specific SysEx commands to make
89 the buttons and lights work.)
91 - Add a disk space indicator to the main window.
93 - Various bugfixes. In particular, an issue where the audio would pitch
94 up sharply after a series of many dropped frames has been fixed.
97 Nageru 1.3.4, August 2nd, 2016
102 Nageru 1.3.3, July 27th, 2016
104 - Various changes to make distribution packaging easier; in particular,
105 theme data can be picked up from /usr/local/share/nageru.
107 - Fix various FFmpeg deprecation warnings, now that we need FFmpeg
108 3.1 for other reasons anyway.
111 Nageru 1.3.2, July 23rd, 2016
113 - Allow limited hotplugging (unplugging and replugging) of USB cards.
114 You can use the new command-line option --num-fake-cards (-C) to add
115 fake cards that show only a single color and that will be replaced
116 by real cards as you plug them in; you can also unplug cards and have
117 them be replaced by fake cards. Fake cards can also be used for testing
118 Nageru without actually having any video cards available.
120 - Add Metacube timestamping of every keyframe, for easier detection of
121 streams not keeping up. Works with the new timestamp feature of
122 Cubemap 1.3.1. Will be ignored (save for some logging) in older
125 - The included default theme has been reworked and cleaned up to be
126 more understandable and extensible.
128 - Add more command-line options for initial audio setup.
131 Nageru 1.3.1, July 1st, 2016
133 - Various display bugfixes.
136 Nageru 1.3.0, June 26th, 2016
138 - It is now possible, given enough CPU power (e.g., a quad-core Haswell or
139 faster desktop CPU), to output a stream that is suitable for streaming
140 directly to end users without further transcoding. In particular, this
141 includes support for encoding the network stream with x264 (the stream
142 saved to disk is still done using Quick Sync), for Metacube framing (for
143 streaming to the Cubemap reflector), and for choosing the network stream
144 mux. For more information, see the README.
146 - Add a flag (--disable-alsa-output) to disable ALSA monitoring output.
148 - Do texture uploads from the main thread instead of from separate threads;
149 may or may not improve stability with NVIDIA's proprietary drivers.
151 - When beginning a new video segment, the shutdown of the old encoder
152 is now done in a background thread, in order to not disturb the external
153 stream. The audio still goes into a somewhat random stream, though.
155 - You can now override the default stream-to-card mapping with --map-signal=
158 - Nageru now tries to lock itself into RAM if it has the permissions to do
159 so, for better realtime behavior. (Writing the stream to disk tends to
160 fill the buffer cache, eventually paging less-used parts of Nageru out.)
162 - Various fixes for deadlocks, memory leaks, and many other errors.
165 Nageru 1.2.1, April 15th, 2016
167 - Images are now updated from disk about every second, so that it is possible
168 to update e.g. overlays during streaming, although somewhat slowly.
170 - Fix support for PNG images.
172 - You can now send SIGHUP to start a new cut instead of using the menu.
174 - Added a --help option.
176 - Various tweaks to OpenGL fence handling.
179 Nageru 1.2.0, April 6th, 2016
181 - Support for Blackmagic's PCI and Thunderbolt cards, using the official
182 (closed-source) Blackmagic drivers. (You do not need the SDK installed, though.)
183 You can use PCI and USB cards pretty much interchangeably.
185 - Much more stable handling of frame queues on non-master cards. In particular,
186 you can have a master card on 50 Hz and another card on 60 Hz without getting
187 lots of warning messages and a 10+ frame latency on the second card.
189 - Many new options in the right click menu on cards: Adjustable video inputs,
190 adjustable audio inputs, adjustable resolutions, ability to select card for
193 - Add support for starting with almost all audio processing turned off
196 - The UI now marks inputs with red or green to mark them as participating in
197 the live or preview signal, respectively. Red takes priority. (Actually,
198 it merely asks the theme for a color for each input; the theme contains
201 - Add support for uncompressed video instead of H.264 on the HTTP server,
202 while still storing H.264 to files (--http-uncompressed-video). Note that
203 depending on your client, this might not actually be more CPU efficient
204 even on localhost, so be sure to check.
206 - Add a simpler, less featureful theme (simple.lua) that should be easier to
207 understand for beginners. Themes are now also choosable with -t on the command
210 - Too many bugfixes and small tweaks to list. In particular, many memory leaks
211 in the streaming part have been identified and fixed.
214 Nageru 1.1.0, February 24th, 2016
216 - Support doing the H.264 encoding on a different graphics device from the one
217 doing the mixing. In particular, this makes it possible to use Nageru on an
218 NVIDIA GPU while still encoding H.264 video using Intel Quick Sync (NVENC
219 is not supported yet) -- it is less efficient since the data needs to be read
220 back via the CPU, but the NVIDIA cards and drivers are so much faster that it
221 doesn't really matter. Tested on a GTX 950 with the proprietary drivers.
223 - In the included example theme, fix fading to/from deinterlaced sources.
225 - Various smaller compilation, distribution and documentation fixes.
