1 Nageru 1.3.2, July 23rd, 2016
3 - Allow limited hotplugging (unplugging and replugging) of USB cards.
4 You can use the new command-line option --num-fake-cards (-C) to add
5 fake cards that show only a single color and that will be replaced
6 by real cards as you plug them in; you can also unplug cards and have
7 them be replaced by fake cards. Fake cards can also be used for testing
8 Nageru without actually having any video cards available.
10 - Add Metacube timestamping of every keyframe, for easier detection of
11 streams not keeping up. Works with the new timestamp feature of
12 Cubemap 1.3.1. Will be ignored (save for some logging) in older
15 - The included default theme has been reworked and cleaned up to be
16 more understandable and extensible.
18 - Add more command-line options for initial audio setup.
21 Nageru 1.3.1, July 1st, 2016
23 - Various display bugfixes.
26 Nageru 1.3.0, June 26th, 2016
28 - It is now possible, given enough CPU power (e.g., a quad-core Haswell or
29 faster desktop CPU), to output a stream that is suitable for streaming
30 directly to end users without further transcoding. In particular, this
31 includes support for encoding the network stream with x264 (the stream
32 saved to disk is still done using Quick Sync), for Metacube framing (for
33 streaming to the Cubemap reflector), and for choosing the network stream
34 mux. For more information, see the README.
36 - Add a flag (--disable-alsa-output) to disable ALSA monitoring output.
38 - Do texture uploads from the main thread instead of from separate threads;
39 may or may not improve stability with NVIDIA's proprietary drivers.
41 - When beginning a new video segment, the shutdown of the old encoder
42 is now done in a background thread, in order to not disturb the external
43 stream. The audio still goes into a somewhat random stream, though.
45 - You can now override the default stream-to-card mapping with --map-signal=
48 - Nageru now tries to lock itself into RAM if it has the permissions to do
49 so, for better realtime behavior. (Writing the stream to disk tends to
50 fill the buffer cache, eventually paging less-used parts of Nageru out.)
52 - Various fixes for deadlocks, memory leaks, and many other errors.
55 Nageru 1.2.1, April 15th, 2016
57 - Images are now updated from disk about every second, so that it is possible
58 to update e.g. overlays during streaming, although somewhat slowly.
60 - Fix support for PNG images.
62 - You can now send SIGHUP to start a new cut instead of using the menu.
64 - Added a --help option.
66 - Various tweaks to OpenGL fence handling.
69 Nageru 1.2.0, April 6th, 2016
71 - Support for Blackmagic's PCI and Thunderbolt cards, using the official
72 (closed-source) Blackmagic drivers. (You do not need the SDK installed, though.)
73 You can use PCI and USB cards pretty much interchangeably.
75 - Much more stable handling of frame queues on non-master cards. In particular,
76 you can have a master card on 50 Hz and another card on 60 Hz without getting
77 lots of warning messages and a 10+ frame latency on the second card.
79 - Many new options in the right click menu on cards: Adjustable video inputs,
80 adjustable audio inputs, adjustable resolutions, ability to select card for
83 - Add support for starting with almost all audio processing turned off
86 - The UI now marks inputs with red or green to mark them as participating in
87 the live or preview signal, respectively. Red takes priority. (Actually,
88 it merely asks the theme for a color for each input; the theme contains
91 - Add support for uncompressed video instead of H.264 on the HTTP server,
92 while still storing H.264 to files (--http-uncompressed-video). Note that
93 depending on your client, this might not actually be more CPU efficient
94 even on localhost, so be sure to check.
96 - Add a simpler, less featureful theme (simple.lua) that should be easier to
97 understand for beginners. Themes are now also choosable with -t on the command
100 - Too many bugfixes and small tweaks to list. In particular, many memory leaks
101 in the streaming part have been identified and fixed.
104 Nageru 1.1.0, February 24th, 2016
106 - Support doing the H.264 encoding on a different graphics device from the one
107 doing the mixing. In particular, this makes it possible to use Nageru on an
108 NVIDIA GPU while still encoding H.264 video using Intel Quick Sync (NVENC
109 is not supported yet) -- it is less efficient since the data needs to be read
110 back via the CPU, but the NVIDIA cards and drivers are so much faster that it
111 doesn't really matter. Tested on a GTX 950 with the proprietary drivers.
113 - In the included example theme, fix fading to/from deinterlaced sources.
115 - Various smaller compilation, distribution and documentation fixes.
118 Nageru 1.0.0, January 30th, 2016
