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'”. + + +Nageru and Futatabi 1.8.6, April 19th, 2019 + + - Filenames for the recordings are now without colons; it caused + too much problems with various software, including most players. + + - Various bugfixes. + + +Nageru and Futatabi 1.8.5, March 30th, 2019 + + - Experimental support for audio in Futatabi: The MJPEG export from + Nageru now supports audio, and Futatabi will store it and play it + back. Audio is currently only supported when playing at 100% speed + (no pitch shift or time stretching), and there is no audio output + to the Futatabi operator. + + - Significant optimizations to MJPEG encoding, both when in use and when + not in use. + + - Various bugfixes. + + +Nageru and Futatabi 1.8.4, March 11th, 2019 + + - Various bugfixes, in particular for 32-bit platforms. + + +Nageru and Futatabi 1.8.3, March 10th, 2019 + + - Allow controlling video mixing from MIDI events. Adapted from a patch + by Yann Dubreuil, from the BreizhCamp repository. + + - Use ALSA hardware timestamps for input; gives more stable delay. + Patch by Yann Dubreuil, from the BreizhCamp repository. + + - For FFmpeg inputs, add an option for playing as fast as possible + (set rate >= 10.0). + + - In Futatabi, support queueing and playing clips with no cue-out point. + This opens up for new and even faster UI workflows. + + - Many bugfixes. + + +Nageru and Futatabi 1.8.2, January 19th, 2019 + + - Futatabi now supports MIDI controllers like Nageru, including an editor + and a sample mapping for the Behringer CMD PL-1. + + - Futatabi now supports changing master speed during play, both via a + MIDI controller and the GUI. + + - Various bugfixes. + + +Nageru and Futatabi 1.8.1, December 30th, 2018 + + - Futatabi can now communicate its queue status through a subtitle track, + and Nageru can consume it. This allows Nageru themes to get precise + information programmatically, e.g. to show status or automatically + switch away when the queue is about to end. + + - Futatabi can now reuse the computed flow across successive frames when + interpolating between the same frame pair. This significantly reduces + the GPU load when doing super-slow motion (slower than 0.5x). + + - Various smaller fixes. + + +Nageru and Futatabi 1.8.0, December 20th, 2018 + + - Initial release of Futatabi, a multicamera slow motion video server + designed to be used with Nageru. Futatabi is currently in alpha stage + and largely undocumented. + + - Add support for multi-camera export from Nageru. A multi-camera stream + contains all frames from all camera inputs (unless overridden by + --mjpeg-export-cards), unprocessed except for MJPEG encoding. + MJPEG encoding is done in hardware (via VA-API) on Skylake or newer, + or using libjpeg otherwise. The intended user of this stream is Futatabi. + + +Nageru 1.7.5, November 11th, 2018 + + - Fix a bug where --record-x264-video would not work when VA-API was + not present, making the option rather useless (broken in 1.7.2). + Bug reported by Peter De Schrijver. + + - The build system has been switched to Meson; see the README for new + build instructions. + + - Various smaller fixes. + + Nageru 1.7.4, August 31st, 2018 - Rework the x264 speedcontrol presets, again.
