* Added USB audio rendering using USB Audio Class 2 Ref: remake-v0.3
Nosumor remake
USB configuration HID port was implemented. It is able to communicate with the host application to flash firmware.

Last week’s project meeting was cancelled.
Implemented audio muxing encoding and decoding, and integrated into the Vixen application.

Placed video encoding and decoding functions in a separate C/C++ library. By using C# interop and DllImport, the library can be used inside C#.

I have implemented video decoding and encoding in C/C++ using ffmpeg. I can now encode the sequence (337MB) to a video file (26.6MB), and then decode it back to the exactly same sequence, losslessly, using h264 with yuv444p pixel format.

A few problems was found by further testing, a new PCB design was sent to manufacturer.

Meeting @19/Jun/2017 was cancelled.
Developed performances profiling on Linux by reading varies statistic files in the /proc/[PID] folder. This can be done on Windows as well, by using the Process class as in CpuUsage.
Options to unlimit playback and/or controller update speeds were implemented, as a baseline for IO/processing performance comparisons across different platforms and architectures.

Will try to read & modify & write video files, as the input/export for playback engine, to enables the use of well established video processing techniques. ffmpeg may be used for media file handling.
Nosumor remake
PCB and most components arrived, the PCB had been built and some basic testing had been done.
