Drivers should provide a wmaxpacketsize range which they need / can

very valid one), while still allowing fallback to a lower alt
setting if the driver can deal with lower settings too, be it by
lowering framerate or by increasing compression (decreasing the
image quality).
It seems a good strategy.
Hi,
That seems fine also to me.
Ok, so one of us needs to write a patch for this (and I'm rather busy
atm). If you do write a patch for this, it would also be good to change
the code which searches for the next lower alt setting to look at
wmaxpacketsize, then the reverse_alts flag can go away, and more
importantly then we will also work properly with cameras which do not
have their alt settings sorted by size at all (I have at least one such
cam).

Hans
