Original commit message from CVS:
Added a tarkin encoder/decoder plugin.
I moved the tarking CVS code in here temporarily until they have a
library (hence this plugin is in ext)
test with:
./gst-launch filesrc location=/opt/data/shihad.mpg ! mpegdemux video_00! { queue ! mpeg2dec ! colorspace ! tarkinenc bitrate=3000 ! disksink location=out.ogg }
./gst-launch filesrc location=out.ogg ! tarkindec ! colorspace ! xvideosink
