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. + + +Nageru 1.3.3, July 27th, 2016 + + - Various changes to make distribution packaging easier; in particular, + theme data can be picked up from /usr/local/share/nageru. + + - Fix various FFmpeg deprecation warnings, now that we need FFmpeg + 3.1 for other reasons anyway. + + +Nageru 1.3.2, July 23rd, 2016 + + - Allow limited hotplugging (unplugging and replugging) of USB cards. + You can use the new command-line option --num-fake-cards (-C) to add + fake cards that show only a single color and that will be replaced + by real cards as you plug them in; you can also unplug cards and have + them be replaced by fake cards. Fake cards can also be used for testing + Nageru without actually having any video cards available. + + - Add Metacube timestamping of every keyframe, for easier detection of + streams not keeping up. Works with the new timestamp feature of + Cubemap 1.3.1. Will be ignored (save for some logging) in older + Cubemap versions. + + - The included default theme has been reworked and cleaned up to be + more understandable and extensible. + + - Add more command-line options for initial audio setup. + + Nageru 1.3.1, July 1st, 2016 - Various display bugfixes.
