Google Code In

This page is about gathering ideas for the x264 project for acceptance in the Google Code In 2010-2011 program.

x264 has been part of Videolan's Google Summer of Code in 2008, 2009 and 2010.

Ideas for x264

Warning

This is a temporary page for listing ideas for Google Code-in tasks.

The final tasks will be moved to melange, when needed.

Tools

Category: Quality Assurance
Description: Automated regression test tool
Details: x264 has no standard regression test tool, and all the developers rely on their own scripts. An automated regression test tool should be able to:

  • Test any two revisions against each other.
  • Test a wide variety of x264 settings combinations. We can help you here by giving you some of the existing scripts.
  • Report the status of a revision: working (basic regression test passes), broken (basic regression test fails), crash, etc.
  • Report the difference between any two revisions (output differs, output is identical, which tests' output differs, etc).

Outcome: A regression test script (in Bash, Perl, Python, or similar)
Difficulty: medium-hard
Tools: x264, JM, ffmpeg, Linux, git
Time: 5 days
Possible Mentors: Jason Garrett-Glaser (Dark Shikari)

CLI development

Category: Video filtering
Description: Port any video filter to x264!
Details: x264 recently got a filtering system that allows users to process video before encoding -- resizing, cropping, and so forth. We'd like to add fancier filters by porting them from other projects, like mplayer's libmpcodecs. These could include denoising, sharpening, blurring, and so forth.

You can pick any filter you want and port it -- just make sure to ask first to make sure that it would make sense in the context of x264.

Do note all filters must reach the code quality standards of x264, so in some cases you may need to do more than just copy-pasting: reformatting code, etc.

Outcome: A new filter in x264.
Difficulty: hard
Tools: x264
Time: 7 days
Possible Mentors: Jason Garrett-Glaser (Dark Shikari), James Darnley (J_Darnley), Steven Walters (kemuri-_9)
