Universal Metadata Framework

The Universal Metadata Framework (UMF) is a C++ library providing functionality for creating, editing and embedding of metadata into video files. UMF allows developers to define and create metadata of any form, and about any resource type. UMF embeds metadata within the host video file or video stream, so that no additional files are needed to store the metadata.

The UMF SDK is developed as a platform-independent C++ library. It is tested on the following operating system:

• MS Windows 7, 8, and 10
• GNU Linux (Ubuntu 14)
• Google Android 4.x, 5.x

The UMF SDK and the sample code use the following C++ 11 features:

• auto
• nullptr
• rvalue references and move semantics
• lambda expressions
• range for
• std::thread

The following C++ compilers are known to compile the UMF SDK and sample code successfully:

• MS VC++ 2013 and newer
• Intel C++ compiler 12.1 and newer
• GNU GCC 4.7 and newer

The library uses the following 3rd party components:

• Adobe XMP Toolkit SDK (http://www.adobe.com/devnet/xmp.html)
• Google C++ Testing Framework (aka GTest, https://code.google.com/p/googletest/)

The UMF SDK uses Doxygen (www.doxygen.org) for API Specification generation.

See docs/UMF_User_guide.pdf for instructions on building and using UMF.

umf's Issues

Could I inject 360 metadata into video with this framework?

Hello. Could I use your framework in iOS to inject 360 metadata into video such like the Google code below done?
https://github.com/google/spatial-media

Compilation under Linux fails

The GCC stops compilation at the following strings:

• samples/metadata-schema/main.cpp:65
• samples/metadata-schema/main.cpp:70
  trying to find matching constructor for std::exception class.

The solution is to use std::runtime_error class instead.

reserved identifier violation

I would like to point out that identifiers like "__VMF_DATASOURCE_HPP__" and "__VMF_IQUERY_H__" do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?

Segmentation fault in Variant::convertTo() method

The toString() method call after calling the release() method at modules/vmfcore/src/variant.cpp:614 leads to segfault.
To reproduce the bug run the checksum-utility sample with some video file as an argument.

Building lib for Android: cannot find -lrt

I use NDK r10b standalone toolschain Building lib for Android ;

run compile_for_android.bat
error info:

[ 91%] Building CXX object modules/CMakeFiles/vmf.dir/vmfcore/src/details/object_factory.cpp.o

I don't know much about librt, but as far as I understand, the NDK does not include librt, but instead integrates some of it's functionality in Android's libc.

How fix this error?
please help me! thanks
