Thanks for all who contacted us! Now we know we can count on you.
Just a small update so that you know the status of the project (and so
that you won't proceed looking into the last described issue, if this
is the case). We have interrupts repeating, and CRC checksums
matching. Now we are working on formatting of h264 stream (the frames
are returned without any headers, and reference driver has header
generation deeply and tightly bound to other code, so this will take
some time.
The latest state of this work in progress is in
github.com/krieger-od/linux.git , branch "brutal".
