Hi Mauro, This is the pull request for the new vicodec driver. The cover letter is here: https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg133594.html One request: the vicodec-codec.h header refers to Tom's report on the Fast Walsh Hadamard Transform: https://hverkuil.home.xs4all.nl/fwht.pdf Can you copy this pdf and put it up somewhere on linuxtv.org and update the link in the header so it points to linuxtv.org? With all the activities ongoing it will be very useful to have this driver in the kernel so we can test and verify APIs.
