Dear all,
Sorry for sending this to multiple list, Im not sure which is the most suitable one for this J We are interested and happy to contribute our open source MPEG-DASH library libdash to your projects. MPEG-DASH is an emerging standard designed for media delivery over the top of existing infrastructures and able to handle varying bandwidth conditions during a streaming session. This requirement is very important, specifically within mobile environments like in 3G/4G networks, which are characterized by highly fluctuating bandwidth conditions, and thus, DASH will become a major driver for mobile multimedia streaming like , e.g., in vehicular or smartphone environments. Our components have already been tested in such vehicular environments (like shown in [1] as well in the short report in [2]) and would fit very well in your environments. In particular we want to highlight our open-source library libdash, which is a C++ library that provides an object orient (OO) interface to the MPEG-DASH standard. You can find more information on our website [3], on the libdash mailing list [4] as well as on Github [5]. This is an overview of the libdash features: · Cross platform build system based on cmake that includes Windows, Linux and Mac. · Open source available and licensed under the LGPL. · Implements the full MPEG-DASH standard according to ISO/IEC 23009-1, Information Technology Dynamic Adaptive Streaming over HTTP (DASH) Part 1: Media Presentation Description and Segment Formats · Handles the download and xml parsing of the MPD. Based on that it provides an OO based interface to the MPD. · Media elements, e.g., SegmentURL, SegmentTemplate, etc., are downloadable in that OO based structure and can be downloaded through libdash, which internally uses libcurl. · Therefore basically all protocols that libcurl supports, e.g., HTTP, FTP, etc. are supported by libdash. · However it also provides a configurable download interface, which enables the use of external connections that can be implemented by the user of the library for the download of media segments. · The use of such external connections will be shown in the libdash_networkpart_test project which is part of libdash solution and also part of the cross platform cmake system and therefore usable on Windows, Linux and Mac. · The project contains a sample multimedia player that is based on ffmpeg which uses libdash for the playback of one of our dataset MPDs. · The development is based on Windows, therefore the code contains a VS10 solution with additional tests and the sample multimedia player. In addition to the public available open source resources and our libdash mailing list support, we provide professional development and integration services, consulting, high-quality streaming components/logics, etc. based on your individual needs. Feel free to contact me so we can discuss your requirements.
