The FFmpeg project has been a participant in the Google Summer of Code program since 2006. In 2011, the Libav fork became part of the same Summer of Code effort.

Each accepted project is developed in its own sandbox, separate from the main FFmpeg / Libav codebase. Naturally, the end goal of each of the accepted projects ought to be to have that code in shape for acceptance into the production codebase. This page tracks the status of each project and how well each student did.

2006 Projects

VC-1 Decoder

AMR-NB Decoder

  • Student: Robert Swain
  • Mentor: Benjamin Larsson
  • Student Status: FFmpeg committer. Project not finished during SoC.
  • Code Status: Continued in another Summer of Code task and accepted into the FFmpeg codebase.

AC-3 Decoder

QCELP Decoder

  • Student: Reynaldo Verdejo Pinochet
  • Mentor: Benjamin Larsson
  • Student Status: FFmpeg commiter. Produced a working decoder during SoC but the code didn't reach SVN before the end of the program.
  • Code Status: Picked up by Kenan Gillet and with the help of Reynaldo committed to FFmpeg. Some features still missing, though.

Matroska Muxer

JPEG 2000 Encoder and Decoder

  • Student: Kamil Nowosad
  • Mentor: Loren Merritt
  • Student Status: disappeared, project unfinished
  • Code Status: The code is working but not all features are supported., committed to FFmpeg.

Dirac Encoder and Decoder

  • Student: Marco Gerards
  • Mentor: Luca Barbato
  • Student Status: project not finished during SoC
  • Code Status: Decoder committed to FFmpeg, the encoder still needs more work.

TS Muxer

  • Student: Xiaohui Sun
