IDRSplit is an open source tool which splits H.264 Annex B bit streams into sequences of pictures consisting of at least one IDR frame each. In most cases, this means that each split sequence will be decodable by itself. For more details and limitations, please see the contained README file.
IDRSplit comes as source code which compiles to an executable file. It is targeted for Linux and has been tested on Ubuntu 14.04 with gcc 4.8.
