Revision as of 07:08, 3 December 2007
The FFmpeg project has been a participant in the Google Summer of Code program during the 2006 and 2007 seaons.
Each accepted project is developed in its own sandbox, separate from the main FFmpeg codebase. Naturally, the end goal of each of the accepted FFmpeg 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
- Student: Kostya Shishkov
- Mentor: Mike Melanson
- Student Status: FFmpeg committer
- Code Status: Accepted into the FFmpeg codebase.
AMR Decoder
- Student: Robert Swain
- Mentor: Benjamin Larsson
- Student Status: project not finished during SoC but continues working on it
- Code Status: Unfinished, but slowly progressing. Narrow band decoding documented on AMR-NB and floating point code has been implemented up to gain decoding.
AC3 Decoder
- Student: Kartikey Mahendra BHATT
- Mentor: Benjamin Larsson
- Student Status: disappeared, project unfinished
- Code Status: Picked up by Justin Ruggles and committed to FFmpeg.
AAC Decoder
- Student: Maxim Gavrilov
- Mentor: Oded Shimon
- Student Status: disappeared, project unfinished
- Code Status: unfinished, orphaned
Vorbis Encoder
- Student: Mathew Philip
- Mentor: Oded Shimon
- Student Status: disappeared, project barely started
- Code Status: Picked up by Oded Shimon and committed to FFmpeg.
2007 Projects
RealVideo 4 Decoder
- Student: Kostya Shishkov
- Mentor: Mike Melanson
- Student Status: FFmpeg committer
- Code Status: in the process of being committed to FFmpeg; the project goal has also morphed to include a RealVideo 3 decoder since the 2 schemes are so similar. Both RV30 and RV40 are decodeable with visual artifacts.
QCELP Decoder
- Student: Reynaldo Verdejo Pinochet
- Mentor: Benjamin Larsson
- Student Status: project not finished during SoC but continues working on it
- Code Status: slowly progressing, it's working though
Matroska Muxer
- Student: David Conrad
- Mentor: Aurélien Jacobs
- Student Status: FFmpeg committer
- Code Status: Accepted into the FFmpeg codebase.
Video Filter API (AKA libavfilter)
- Student: Bobby Bingham
- Mentor: Benjamin Larsson and Michael Niedermayer
- Student Status: project not finished during SoC but continues working on it
- Code Status: Working code for ffplay and ffmpeg. Colorspace negotiation needs some work. Still in development (albeit slowly) by Bobby Bingham and Vitor.
E-AC3 Decoder
- Student: Bartlomiej Wolowiec
- Mentor: Justin Ruggles
- Student Status: project not finished during SoC, (continues working on it?)
- Code Status: Working for most available samples. There are still some unimplemented features though. The code is currently not clean enough for inclusion in FFmpeg.
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.
Dirac Encoder and Decoder
- Student: Marco Gerards
- Mentor: Luca Barbato
- Student Status: project not finished during SoC but continues working on it, just slower than before due to other tasks taking priority.
- Code Status: The decoder is in good shape, the encoder still needs more work.
TS Muxer
- Student: Xiaohui Sun
- Mentor: Baptiste Coudurier
- Student Status: disappeared, project unfinished
- Code Status: Changes requested during the review process for FFmpeg inclusion were never made.
