When input is H.264 they don't have pts/dts sometimes before decoder, but
dropping non-dated packets screw up decoder.

This reverts commit 57b356e2.

Use fps video filter for framerate conversion. Also do framerate conversion
after deinterlacer so we don't screw deinterlacing with frame dropping.

Also reduce intentation of code.

If user doesn't give videobitrate use some reasonable default to get ok output
from avcodec transcode (for example mpeg4 video).

Everybody should install the underlying libraries somewhere and, if
necessary, pass --with-* to specify the installation path (this is
automatic for VLC contribs).

Refactor so deinterlacer/scaler is fed with all input pictures and not only
ones that encoder needs.

Auto-detect current osx version, overwrite path to avoid influences
from macports or homebrew.

Close #12856

This commit modifies the convert wizard to accept multiple files from the file dialog box

The GUI should operate the same when a single file is selected (providing
an option of where and what to name the file), but when multiple files are
selected the files are placed into the same folder with the same name and a
new extention (there is an option to append -converted if you are converting
to the same extention).
There are some tooltips to explain this operation.

Most of the changes are pretty straight-forward, converting QStrings to
QStringLists and passing the full list of MRLs around. The playlist already
supports the batch processing in a pretty straightforward way, so there's no
issues there.

StandardPanel.cpp was modified to create a temp QStringList for passing to the
streamingDialog, as it now takes the full list of input files rather than just
one

Convert.cpp/hpp modified to take the QStringList and to behave (semi)-intelligently when reciving multiple files,
Open.cpp modified to pass the MRLs rather than MRL[0]
and the Dialogs_provider.cpp/hpp to pass the MRLs along, pretty much.

It also clears the playlist when recieving a list and starts the playlist from the beginning when it's added all the files to be converted.
