Playing a digital media is something complex, that requires non-trivial code. Such code is likely to have unknown security issues. It is therefore unwise to trust such code to handle untrusted data, such as a cat video[1] from the internet.
One solution that could be applied to GStreamer is to run the non-trivial code inside a sandbox. Gillaume has experimented a bit[2] with the idea and would like to expose his preliminary results.

Transcript

  • 1. Guillaume Emont Igalia
  • 2. Internets = cute videos of [insert favourite animal]
  • 3. Trustworthy?
  • 4. Complex software written by human beings can have bugs.
  • 5. sandboxeddecodebin
  • 6. Biggest limitations so far: • no upstream communication => no seeking • overhead: 720p ogg/theora on my i5: 20-30% -> 30-40% cpu
  • 7. Potential solutions: • better wrapper around the sandboxed part of the pipeline (with upstream communication) • put the whole pipeline in the sandbox
  • 8. Thank You guijemont@igalia.com http://guij.emont.org/blog/ https://github.com/guijemont/Sandboxed-Player Image Credits: Sandbox: Public Domain by Hyena http://en.wikipedia.org/wiki/File:Sandpit.jpg beer: CC BY-NC-SA 2.0 Martin Ibert http://www.flickr.com/photos/mar_ibert/
