[FFmpeg-devel] [PATCH v4 09/13] avdevice: add info about media types(s) to AVDeviceInfo

[Diederick Niehorster]

An avdevice, regardless of whether its category says its an audio or
video device, may provide access to devices providing different media
types, or even single devices providing multiple media types. Also, some
devices may provide no media types. dshow is an example encompassing all
of these cases. Users should be provided with this information, so
AVDeviceInfo is extended to provide it.

Bump avdevice version
