A UK forensics agency required plug-and-play decoding modules in order to extract digital video footage within an Open Source video playback framework.

Forensic examination and analysis of digital media and systems is a significant resource in the evidentiary support of prosecution cases and modern forensics. The clarity and accuracy of the decoded digital footage is critical, as it can be used as evidence in a court of law.

LeoTel Software Systems worked in a technology partnering role, developing modular tools and resources in order to allow playback of the desired footage within the Open Source video playback framework, and frame-by-frame examination of footage.

Prior to designing the plug-in modules for each codec, the source data was reverse-engineered and audio and video streaming manipulation techniques were applied in order to ensure that suitable playback from the source hard disc was not only possible but yielded the desired quality required for evidentiary support.

LeoTel developed plug-in modules to handle the decoding of specific data and proprietary formats within the context of the Open Source video playback framework.

The development of the codecs required a detailed knowledge of C, Java, Linux, FFMPEG, image decoding and processing techniques, and MPEG 4 and H.264 file formats.

  • Significant time saved acquiring the desired footage;
  • Ease of use by forensic analysts;
  • Higher efficiency and speed of searching and targeting;
  • Consistent decode and playback quality;
  • Analysis of a wider range of digital footage sources is now possible.
