Last year, we tried - and succeeded - to build a distribution chain for distributing audiovisual material over the public internet. At that time, there were 3 competing standards (Apple’s, Microsoft’s and Adobe’s). Each provided an adaptive, http-based delivery, each with their own, vertically integrated, software components to encode and distribute the content. We combined ffmpeg, x264 and MP4box for the encoding side. Apache and mod_smoothstreaming took care of the distribution side. The whole workflow was glued together with some bash scripts and automake-magic. The result is a single working toolchain, serving the three formats from a single disk-format.


As a telecommunications engineer, Niels Laukens has an academic background in modern telecommunication systems, including IP-multicast, cryptographic and other technologies. As a sr.researcher in the R&D department of VRT, he works on contribution connectivity issues. His main focus is on the backend of the contribution/distribution chain, encompassing encoding and server software, communication links, and back-end architecture design and development. Recent projects include adaptive streaming technologies and scalable server architecture for second screen applications in live television shows.
