1 Nageru 1.3.0, not released yet
3 - It is now possible, given enough CPU power (e.g., a quad-core Haswell or
4 faster desktop CPU), to output a stream that is suitable for streaming
5 directly to end users without further transcoding. In particular, this
6 includes support for encoding the network stream with x264 (the stream
7 saved to disk is still done using Quick Sync), for Metacube framing (for
8 streaming to the Cubemap reflector), and for choosing the network stream
9 mux. For more information, see the README.
11 - Add a flag (--disable-alsa-output) to disable ALSA monitoring output.
13 - Do texture uploads from the main thread instead of from separate threads;
14 may or may not improve stability with NVIDIA's proprietary drivers.
16 - When beginning a new video segment, the shutdown of the old encoder
17 is now done in a background thread, in order to not disturb the external
18 stream. The audio still goes into a somewhat random stream, though.
21 Nageru 1.2.1, April 15th, 2016
23 - Images are now updated from disk about every second, so that it is possible
24 to update e.g. overlays during streaming, although somewhat slowly.
26 - Fix support for PNG images.
28 - You can now send SIGHUP to start a new cut instead of using the menu.
30 - Added a --help option.
32 - Various tweaks to OpenGL fence handling.
35 Nageru 1.2.0, April 6th, 2016
37 - Support for Blackmagic's PCI and Thunderbolt cards, using the official
38 (closed-source) Blackmagic drivers. (You do not need the SDK installed, though.)
39 You can use PCI and USB cards pretty much interchangeably.
41 - Much more stable handling of frame queues on non-master cards. In particular,
42 you can have a master card on 50 Hz and another card on 60 Hz without getting
43 lots of warning messages and a 10+ frame latency on the second card.
45 - Many new options in the right click menu on cards: Adjustable video inputs,
46 adjustable audio inputs, adjustable resolutions, ability to select card for
49 - Add support for starting with almost all audio processing turned off
52 - The UI now marks inputs with red or green to mark them as participating in
53 the live or preview signal, respectively. Red takes priority. (Actually,
54 it merely asks the theme for a color for each input; the theme contains
57 - Add support for uncompressed video instead of H.264 on the HTTP server,
58 while still storing H.264 to files (--http-uncompressed-video). Note that
59 depending on your client, this might not actually be more CPU efficient
60 even on localhost, so be sure to check.
62 - Add a simpler, less featureful theme (simple.lua) that should be easier to
63 understand for beginners. Themes are now also choosable with -t on the command
66 - Too many bugfixes and small tweaks to list. In particular, many memory leaks
67 in the streaming part have been identified and fixed.
70 Nageru 1.1.0, February 24th, 2016
72 - Support doing the H.264 encoding on a different graphics device from the one
73 doing the mixing. In particular, this makes it possible to use Nageru on an
74 NVIDIA GPU while still encoding H.264 video using Intel Quick Sync (NVENC
75 is not supported yet) -- it is less efficient since the data needs to be read
76 back via the CPU, but the NVIDIA cards and drivers are so much faster that it
77 doesn't really matter. Tested on a GTX 950 with the proprietary drivers.
79 - In the included example theme, fix fading to/from deinterlaced sources.
81 - Various smaller compilation, distribution and documentation fixes.
