The next pointer is kept at the end for backwards compatability until the
major bump, when it should ideally be moved at the front.

Current if statement would always be false due to assigning the value of
S_OK which equals 0.

actually have both video and audio output pins, so make the audio pins
accessible by video source name.

dshow_capture.h sets up various flags before including windows headers
this must occur before other headers (like os_support.h) include these
headers without the setup
This could be fixed differently but for now this fixes building on mingw

Basically sometimes if you start dropping video packets, you also drop audio packets. Now they each have separate buffers to avoid this unexpected behavior.

The constant may change in libavutil but the library may be compiled
against an older version, thus rejecting a value which is otherwise
supported by the new libavutil.
INT_MAX is used here to denote the max allowed value for a pixel format.
The opt-test code is changed to provide a valid reference example.
Handling DirectShow events prevents infinite loops when there is an error in
the graph, such as a device being disconnected. This makes it possible for
dshow to return an error to the caller and run the cleanup code.
Based on patch by Don Moir <donmoir@comcast.net>.
Successfully opening a device altered the ret variable, making the function
not cleanup properly and return an incorrect value for errors that happened
afterwards.

This change requires the user to specify min and max value, and makes
possible to prevent the user to set AV_{SAMPLE,PIX}_FMT_NONE if
forbidden.
Add required ifdeffery in case of mixed libraries, when libavutil is
updated but not the other libraries.
This is a followup of 08d0969c14.
Use the i64 field rather than the string value. Using a string to set a
default sample/pixel format is weird, also the new interface is more
consistent with the rest of the API.
This is technically an API break, but hopefully there are no applications
using this feature outside of FFmpeg. In order to save backward
compatibility with mixed libraries in case libavutil is updated but not
the other libraries, some ifdeffery hacks are added.
Note that the version check is only performed when class->version != 0,
since if it is not defined then we assume that no version was defined and
the class is not affected by the change.
We will luckily get rid of the hack at the next major bump.
