Thats the most critical. v4l2 allows some optimizations which are impossible with v4l1 (because the format is fixed one can easily reuse risc code for the buffers, ...), thats why I expect that handling v4l1 grabbing natively in the driver works much better than trying to create some common compatibility layer for it. Everything else should be easy to handle with some helper functions. Gerd -- Protecting the children is a good way to get a lot of adults who cant stand up for themselves. -- seen in some sig on /.
