+Nageru and Futatabi 2.0.2, September 3rd, 2021
+
+ - Fix issues with various upstream software:
+ DeckLink 11.7 (and newer) drivers, FFmpeg 4.4, newer CEF.
+
+ - Add a --no-transcode-video flag to Kaeru.
+
+ This is useful primarily if you want Kaeru to rewrap the stream into
+ Metacube (for Cubemap) and do nothing else with it. Only H.264
+ is supported for now, since everything else assumes that.
+
+
+Nageru and Futatabi 2.0.1, July 9th, 2020
+
+ - Upgrade DeckLink SDK to 10.11.4.
+
+ - Various bugfixes.
+
+
+Nageru and Futatabi 2.0.0, June 2nd, 2020
+
+ - Native support for SRT inputs; by default, Nageru will listen
+ for incoming connections on port 9710 and treat them as hotplugged
+ cameras. They do not need any special handling in the theme,
+ and can pick up e.g. the SRT stream ID to be used in the UI.
+ They generally have fewer limitations than using an srt:// URL
+ on an FFmpeg capture; e.g., there is no forced scaling, and they
+ can be used as master clock (although this is not generally
+ recommended).
+
+ For license reaseons, please be sure that libsrt does not link to
+ OpenSSL when building Nageru.
+
+ - You do no longer need to set up a fixed amount of capture cards
+ at startup; by default, at least two will be created for you
+ (fake capture cards) as before, but if you have more, or hotplug
+ more, more slots will be automatically available, and will go
+ away (not take up any resources like fake capture cards do)
+ when unplugged. If you wish to artificially limit the maximum
+ number of cards like before, you can use the new switch
+ --max-num-cards.
+
+ - MJPEG handling now includes 4:2:0 support in both Nageru and
+ Futatabi, as SRT inputs are often 4:2:0 and not 4:2:2.
+
+ - FFmpeg capture cards (including SRT cards) now use VA-API
+ hardware acceleration for decoding whenever available.
+
+
+Nageru and Futatabi 1.9.3, April 12th, 2020
+
+ - Support (video-only) V4L2 output. The intended use case is output into
+ v4l2loopback to get into videoconferencing or the likes:
+
+ sudo apt install v4l2loopback-dkms
+ sudo modprobe v4l2loopback video_nr=2 card_label='Nageru loopback' max_width=1280 max_height=720 exclusive_caps=1
+ nageru --v4l-output /dev/video2
+
+ Start Nageru before any readers.
+
+
+Nageru and Futatabi 1.9.2, March 29th, 2020
+
+ - Support handling white balance directly in Nageru, without themes
+ manually inserting a WhiteBalanceEffect or handling set_wb().
+ To use it, call scene:add_white_balance() instead of
+ scene:add_effect(WhiteBalanceEffect.new()). If using this functionality,
+ white balance will be properly propagated to the MJPEG feed and
+ through Futatabi, so that replays get the correct white balance.
+ Futatabi's UI will still be uncorrected, though.
+
+ - Make it possible to siphon out a single MJPEG stream, for remote
+ debugging, single-camera recording, single-camera streaming via
+ Kaeru or probably other things. The URL for this is /feeds/N.mp4
+ where N is the card index (starting from zero).
+
+ - The theme can now access some audio settings; it can get (not set)
+ number of buses and names, get/set fader volume, get/set mute,
+ and get/set EQ parameters.
+
+ - In Futatabi, it is now possible to set custom source labels, with
+ the parameter --source-label NUM:LABEL (or -l NUM:LABEL).
+
+ - When the playback speed changes in Futatabi, ease into the new speed.
+ The easing period is nominally 200 ms, but it will be automatically
+ shortened or lengthened (up to as much as two seconds in extreme
+ cases, especially involving very slight speed change) if this
+ helps getting back into a cadence of hitting the original frames.
+ This can mean significant performance improvements when ramping
+ from higher speeds back into 100%.
+
+ - Updates for newer versions of CEF (tested with Chrome 80).
+
+ - Various bugfixes and performance improvements.
+
+
+Nageru and Futatabi 1.9.1, November 17th, 2019
+
+ - Support disabling optional effects if a given other effect is _enabled_
+ (typically for mutually exclusive effects).
+
+ - Make it possible for the theme to override the status line, by declaring
+ a function format_status_line() in the theme. Inspired by a C++ patch by
+ Alex Thomazo in the Breizhcamp repository.
+
+ - Various bugfixes.
+
+
+Nageru and Futatabi 1.9.0, July 20th, 2019
+
+ - Significant reworking of the theme engine: Chains (now called scenes)
+ can now instantiate different versions behind-the-scenes instead of the
+ user having to worry about input types, low/high quality, or replacing
+ effects with others. Menus can have submenus and checkboxes. Finally, some
+ callbacks, such as num_channels(), have been replaced with easier-to-use
+ imperative functions, ie., an explicit call to Nageru.set_num_channels(N).
+
+ See the documentation for more information, or the included themes,
+ which have been ported to the new interfaces. Existing themes will continue
+ to run without modification, but the old interfaces are deprecated.
+
+ Martin Sandsmark contributed a bugfix to this work.
+
+ - Support cross-compilation. Patch from Helmut Grohne.
+
+ - Kaeru now has a parameter --disable-audio for transcoding streams
+ with no audio.
+
+ - Various bugfixes. In particular, work around an issue where Mesa's shader
+ cache interacts with Qt's EGL support to create a confusing crash with
+ “vertex shader lacks `main'”.
