c++ - Building WMF (Windows Media Foundation) mediadriver plugin for Qt on Windows 10 -


i've downloaded , installed msvc compiled qt 5.7 qt official download page via online installer windows 10.

i try create media player application uses qvideoprobe. apparently there are 2 mediadriver plugins (or multimedia backends) windows. directstreamer , media foundation (mf or wmf). both has limitations. can capture video directstreamer qvideoprobe not supported. on wmf side it's on contrary. can't use camera capture wmf qvideoprobe supported.

my problem qt comes directstreamer default. can found @ <qt-install-path>\5.7\msvc2015_64\plugins\mediaservice\dsengine.dll understand have build , deploy wmf plugin myself didn't find documentations or tutorials.

if 1 downloads qt source (also available in download page) source code of plugin can found in <qt-src-path>\qt-everywhere-opensource-src-5.7.0\qtmultimedia\src\plugins\wmf directory.

my questions: how create plugin sorce existing qt install? need additional libraries or other stuff windows? can find tutorials this? did searching (media backend plugin building) seems white spot.

thanks help!

ok, apparently easier thought. here did:

  1. installed qt 5.7 online installer
  2. installed visual studio , debugging tools windows
  3. downloaded source qt 5.7 official download page
  4. downloaded , installed qtcreator official download page. if order correct ide automatically recognized kit (with compiler , debugger).
  5. copied source qt directory (into <qt-install-path>\5.7\src)
  6. opened qmultimedia project qtcreator (located under <qt-install-path>\5.7\src\qtmultimedia)
  7. build qmultimedia
  8. build plugins/wmf subproject separately

and under build directory (under <build-path>\plugins\) wmfengine.dll appeared.
