Summer of Code 2008

DRAFT

This is a draft proposal for Google Summer of Code projects with Xiph.org.

We need a primary and backup mentor volunteer for each of these.

Optimize Theora encoding/decoding speed, SSE/SSE2

working on SSE/SSE2 implementations of the crucial encoding and decoding elements in libtheora. this could continue in theora-exp where with ruik's work or consolidate theora-mmx, theora-oil in trunk

Theora reference encoder quality optimization

the libtheora encoder could make more use of some features present in the spec but not currently implemented in the encoder.

Encode support in theora-exp

Implement a rate-distortion optimized encoding mode for theora-exp, including R-D optimzed mode decision and quantization (e.g., constant lambda). Then, use the above routines to implement a medium-latency ABR encoding mode (e.g., varying lambda), with a default target buffer size of approximately 2 seconds.

Hardware implementation of Theora decoding

working on a hardware theora decoder, that can be used in embedded devices, dvd players and video pods. Presumedly GPL verilog source to run on an FPGA.

Ogg Dirac mapping and integration in players

this could be a) writing down the spec for ogg dirac that is floating around on the dirac and carid mailing list and implementing it in i.e. vlc or gstreamer.

j^ note: in whats state is ogg dirac right now anyway?

rillian note: OggDirac is pretty much waiting on carid and a spec revision from Tim at the BBC, but maybe ds would like help.

Subtitle Editor

this project would also consolidate the various proposals for subtitles. from what i saw on #annodex, using CMML might be the way to go.
