Résumé

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.
