Today Steinwurf released two projects under the BSD License:
Petro – an mp4 file parser. The parser is very configurable which means it can be made to handle exactly the boxes/atoms which are of importance to any given use case. To see the library in action refer to the included examples for, e.g., extracting h264 or AAC from mp4 files.
Bourne – a simple c++11 json reader and writer, see the included example for a quick overview of the API.
