I would like to get DVD seeking in and some recent bugfixes (initial
patchset was sent, working on revision). I'm chasing one last
lingering issue with chapter-based extraction.
Hopefully, I can make a breakthrough or get help to fix it soon.
Beyond that I plan to leave DVD alone for a long time.

The need for this patch arose while attempting to live stream a DASH
feed with low latency. Since I did not use a timeline, having an
accurate start time became crucial. Without it, the player might
download segments at incorrect times. Currently, the start time is set
to the system time, which mig

Hi all,
I have worked on implementing some new features for computing enhanced SSIM
(minkowski pooling and using integral images). As of right now I have done so
