libdash is a computer software library which provides an object-oriented interface to the Dynamic Adaptive Streaming over HTTP (DASH) standard.

It is also the official reference implementation of the ISO/IEC MPEG-DASH standard,[3] and maintained by the Austrian company bitmovin.

The libdash source code is open source, published at GitHub,[4] and licensed under the GNU Lesser General Public License 2.1+.
