Features (those marked with * are still in progress or not started yet):
- High performance on modest hardware (720p60 with two input streams
- on my Thinkpad X240); almost all pixel processing is done on the GPU.

- High output quality; Lanczos3 scaling, subpixel precision everywhere,
- white balance adjustment (*), mix of 16- and 32-bit floating point
+ white balance adjustment, mix of 16- and 32-bit floating point
for intermediate calculations, dithered output.
- Proper sound support: Syncing of multiple unrelated sources through
pipelines causing transitions etc., so that the visual look is consistent
between operators.
+[1] For reference, that is: Core i7 4600U (dualcore 2.10GHz, clocks down
+to 800 MHz after 30 seconds due to thermal constraints), Intel HD Graphics
+4400 (ie., without the extra L4 cache from Iris Pro), single-channel DDR3 RAM
+(so 12.8 GB/sec theoretical memory bandwidth, shared between CPU and GPU).

Nageru is in alpha stage. It currently needs:
It is strongly recommended to have the rights to run at real-time priority;
it will make the USB3 threads do so, which will make them a lot more stable.
(A reasonable hack for testing is probably just to run it as root using sudo,
-although you might not want to do that in production.)

+performance.
Nageru will open a HTTP server at port 9095, where you can extract a live
H264+MP3 signal in MPEG-TS mux (e.g. http://127.0.0.1:9095/stream.ts).
