XEmacs + Xft == Awesome

Sunday, May 24, 2009 by Jai

So I finally decided to give the XEmacs 21.5 beta branch a try, mostly because Eric Knauel and Mathias Neubauer's Xft patches had been finally merged into the beta branch along with lots of other stuff. You know what that means though, antialiased fonts :)

(Yes, I'm as shallow as the next geek you meet on the street and care about these things)

GSoC 09

Tuesday, May 19, 2009 by Jai

In the last "update" post, I neglected to mention that my application to FFmpeg was accepted this year as well. So this summer, I'll try and get a native JPEG2000 codec merged into FFmpeg. As of now there are no updates because I'm too lazy to start :)

Should be a fun summer though....

Well, its been a very long time since I wrote anything here. But I have been keeping myself busy :) , mostly with FFmpeg.

Here is a list (well, sort of) :

  • Finally got around to writing a wrapper for OpenJPEG [link], so JPEG2000 native support is all that remains on that front.
  • Fixed a bunch of bugs before the 0.5 release. One of the more important ones was the DVD Audio Substream handling patch [link]. Still can't believe we actually did a release :)
  • Added decent seeking support to the Nullsoft Video demuxer alongwith some general cleanup [link]. Now its less annoying when I watch my insanely old Southpark season 1-3 rips.
  • Basic support for MPEG4 ALS [link]. Then again, no. of channels is not read correctly, I should get around to commiting that soon. Also there is ALS-in-MP4 muxing which is complicated by the stupidity of the reference code. I should probably send a patch to the people who standardize ALS :) Meh.

Probably missed something but who cares....
