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 noe 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. (They earlier assumed + we could control B-frame settings on the fly, which we cannot with + threaded lookahead.) Also support x264 >= 153, which can support + multiple bit depths in the same library. + + - Default to SDI inputs instead of HDMI. + + - Add a mode to run in full screen (--fullscreen). Adapted from a patch + by Yoann Dubreuil. + + - Add support for lift/gamma/gain in the theme. Patch by Alexandre Thomazo. + + +Nageru 1.7.3, May 22nd, 2018 + + - When using multichannel audio, add a control for adjusting the + stereo width (from normal stereo to mono, all the way to + inverted stereo). + + - Removed --http-coarse-timebase (it is now always on). + + - Various bugfixes. + + +Nageru 1.7.2, April 28th, 2018 + + - Several improvements to video (FFmpeg) inputs: You can now use + them as audio sources, you can right-click on video channels + to change URL/filename on-the-fly, themes can ask for forced + disconnection (useful for network sources that are hanging), + and various other improvements. Be aware that the audio support + may still be somewhat rough, as A/V sync of arbitrary video + playout is a hard problem. + + - The included themes have been fixed to properly make the returned + chain preparation functions independent of global state (e.g. if + the white balance for a channel was changed before the frame was + actually rendered). If you are using a custom theme, you may want + to apply similar fixes to it. + + - In Metacube stream output, mark each keyframe with a pts metadata + block. This allows Cubemap 1.4.0 or newer to serve fMP4 fragments + for HLS from Nageru's output, without any further remuxing or + transcoding. + + - If needed, Nageru will now automatically try to autodetect a + usable --va-display parameter by probing all DRM nodes for H.264 + encoders. This removes the need to set --va-display in almost all + cases, and also removes the dependency on libpci. + + - For GPUs that support querying available memory (in practice only + NVIDIA GPUs at the current time), expose the amount of used/total + GPU memory both on standard output and in the Prometheus metrics + (as well as included Grafana dashboard). + + - The Grafana dashboard now supports heatmaps for the chosen x264 + speedcontrol preset (requires Grafana 5.1 or newer). (There used to + be a heatmap earlier, but it was all broken.) + + - Various bugfixes. + + +Nageru 1.7.1, March 26th, 2018 + + - Various bugfixes, mostly related to HTML and video inputs. + + +Nageru 1.7.0, March 8th, 2018 + + - Support for HTML5 graphics directly in Nageru, through CEF + (Chromium Embedded Framework). This performs better and is more + flexible than integrating with CasparCG over a socket. Note that + CEF is an optional component; see the documentation for more + information. + + - Add an HTTP endpoint for enumerating channels and one for getting + only their colors. Intended for remote tally applications; + set the documentation. + + - Add a video grid display that removes the audio controls and shows + the video channels only, potentially in multiple rows if that makes + for a larger viewing area. + + - Themes can now present simple menus in the Nageru UI. See the + documentation for more information. + + - Various bugfixes. + + +Nageru 1.6.4, January 25th, 2018 + + - Fix compilation with the upcoming FFmpeg 3.5. + + - Switch to LuaJIT for the theme engine, which is faster. + + - Various bugfixes and smaller optimizations. + + +Nageru 1.6.3, November 8th, 2017 + + - Add quick-cut keys (Q, W, E, etc.) below the preview keys. + Since it's easy to hit these by accident and put up a signal + you didn't want, they are disabled by default (they can be + enabled in the video menu, or with the command line flag + --quick-cut-keys). + + - Rework the x264 speedcontrol presets to better match newer + x264 versions. + + - Add an option for changing the HTTP port (--http-port). + + - Various smaller bug and integration fixes. + + +Nageru 1.6.2, July 16th, 2017 + + - Various smaller Kaeru fixes, mostly around metrics. Also, + you can now adjust the x264 bitrate in Kaeru (in 100 kbit/sec + increments) by sending SIGUSR1 (higher) or SIGUSR2 (lower). + + +Nageru 1.6.1, July 9th, 2017 + + - Add native export of Prometheus metrics. + + - Rework the frame queue drop algorithm. The new one should handle tricky + situations much better, especially when a card is drifting very slowly + against the master timer. + + - Add Kaeru, an experimental transcoding tool based on Nageru code. + Kaeru can run headless on a server without a GPU to transcode a + Nageru stream into a lower-bitrate one, replacing VLC. + + - Work around a bug in some versions of NVIDIA's OpenGL drivers that would + crash Nageru after about three hours (fix in cooperation with Movit). + + - Fix a crash with i965-va-driver 1.8.x. + + - Reduce mutex contention in certain critical places, causing lower tail + latency in the mixer. + + +Nageru 1.6.0, May 29th, 2017 + + - Add support for having videos (from file or from URL) as a separate + input channels, albeit with some limitations. Apart from the obvious use of + looping pause clips or similar, this can be used to integrate with CasparCG; + see the manual for more details. + + - Add a frame analyzer (accessible from the Video menu) containing an + RGB histogram and a color dropped tool. This is useful in calibrating + video chains by playing back a known signal. Note that this adds a + dependency on QCustomPlot. + + - Allow overriding Y'CbCr input interpretation, for inputs that don't + use the correct settings. Also, Rec. 601 is now used by default instead + of Rec. 709 for SD resolutions. + + - Support other sample rates than 48000 Hz from bmusb. + + +Nageru 1.5.0, April 5th, 2017 + + - Support for low-latency HDMI/SDI output in addition to (or instead of) the + stream. This currently only works with DeckLink cards, not bmusb. See the + manual for more information. + + - Support changing the resolution from the command line, instead of locking + everything to 1280x720. + + - The A/V sync code has been rewritten to be more in line with Fons + Adriaensen's original paper. It handles several cases much better, + in particular when trying to match 59.94 and 60 Hz sources to each other. + However, it might occasionally need a few extra seconds on startup to + lock properly if startup is slow. + + - Add support for using x264 for the disk recording. This makes it possible, + among other things, to run Nageru on a machine entirely without VA-API + support. + + - Support for 10-bit Y'CbCr, both on input and output. (Output requires + x264 disk recording, as Quick Sync Video does not support 10-bit H.264.) + This requires compute shader support, and is in general a little bit + slower on input and output, due to the extra amount of data being shuffled + around. Intermediate precision is 16-bit floating-point or better, + as before. + + - Enable input mode autodetection for DeckLink cards that support it. + (bmusb mode has always been autodetected.) + + - Add functionality to add a time code to the stream; useful for debugging + latency. + + - The live display is now both more performant and of higher image quality. + + - Fix a long-standing issue where the preview displays would be too bright + when using an NVIDIA GPU. (This did not affect the finished stream.) + + - Many other bugfixes and small improvements. + + +Nageru 1.4.2, November 24th, 2016 + + - Fix a thread race that would sometimes cause x264 streaming to go awry. + + +Nageru 1.4.1, November 6th, 2016 + + - Various bugfixes. + + +Nageru 1.4.0, October 26th, 2016 + + - Support for multichannel (or more accurately, multi-bus) audio, + choosable from the UI or using the --multichannel command-line + flag. In multichannel mode, you can take in inputs from multiple + different sources (or different channels on the same source, for + multichannel sound cards), apply effects to them separately and then + mix them together. This includes both audio from the video cards + as well as ALSA inputs, including hotplug. Ola Gundelsby contributed + invaluable feedback on this feature throughout the entire + development cycle. + + - Support for having MIDI controllers control various aspects of the + audio UI, with relatively flexible mapping. Note that different + MIDI controllers can vary significantly in what protocol they speak, + so Nageru will not necessarily work with all. (The primary testing + controller has been the Akai MIDImix, and a pre-made mapping for + that is included. The Korg nanoKONTROL2 has also been tested and + works, but it requires some Korg-specific SysEx commands to make + the buttons and lights work.) + + - Add a disk space indicator to the main window. + + - Various bugfixes. In particular, an issue where the audio would pitch + up sharply after a series of many dropped frames has been fixed. + + Nageru 1.3.4, August 2nd, 2016 - Various bugfixes.
