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. (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.
