We had quite a bit of code dedicated to handled GstPipeline monitoring
inside GstValidateBinMonitor, cleanly split that code into a new object
type
https://bugzilla.gnome.org/show_bug.cgi?id=740704
+ Defines reporting levels and document them.
+ Add API to get the default level.
+ fix indentation.
+ fix some typos.
+ Add the beginning of a reporting test.
This struct stores information about a media and tests run on it. It
also has a few helper functions that allows storing the results to a
file and loading it back.
Instead of having the file-checker object that would compare the
extracted values from the file to expected results set to its properties,
the media-info will store the values and it will be possible to compare
old media-info with new media-info from the same file. This allows
tracking improvements and regressions on different gstreamer versions.
Right now, the media-info is very tiny and doesn't store much info, only
the uri and the file size in bytes, but it will receive more additions in
the upcoming commits for storing duration, media topology, seekability and
playback information.
