I think %tmp% should always be writtable.

Width and height are independent for step-wise frame sizes (yes,
enumerating is slow). Continuous frame sizes are step-size with one

Fix build with mingw-w64

value for maximum bitrate does not really matter in these cases as

Make sure the context callback is registered only after the stream
is created, and unregistered before the stream is destroyed. This
should fix a potential assertion failure when stopping audio.

And convert tabs to 4 spaces according to code guidelines.

This atom can store an optionnal aspect ratio.
