Back in August 2009 I was chatting with my old peers in Mexico, and they told me that they needed a JPEG parser element in GStreamer for their DSP accelerated JPEG decoder. So, I went to bugzilla and found a bug report about the issue and a proposed patch. But the published patch still missed some features so I took it and worked on it.
After attaching my first try, Arnout, the first author of the patch, came with some comments to improve the element. Several weeks after I retook the element and almost rewrote it again. So I was waiting for the OK from a GStreamer developer.
Finally, this week, Stefan review it and pushed it. Sadly for me, I didn’t notice, when I rebased my local commits, squashing my change set into one single commit, that this commit had as author Arnout, not me 
Now the commit is under the Arnout’s credit.
Yeah, sometimes I’m so absentminded.
That sucks. Hopefully you’ll find another patch for redemption. Maybe a gst-dsp jpegdec
Squashing is evil. You should have left his commit unmodified and work on top of it…
