The >buffers are still there, they've just moved. You missed some messages? Yes, the buffers are still there, internal to the driver. They just aren't mmapped because the data in the internal buffers is in format which is not understood by any user application anyway (except my special test program). Hopefully Gstreamer changes this by allowing me to write an user space format conversion module as Gstreamer plugin, and then I could directly mmap the custom format buffers and still have all applications (using Gstreamer) to work. Unfortunately I haven't yet had time to do this.
