Allow additional arguments on watermark filter
Make positions optional (use -1 for posX and posY) and then use the setAddArgument() method

• Make FFMPEGLocator.createExecutor() to allow it to be used in other contexts
• added execute method to FFMPEGExecutor to leave the ffmpeg processes running after JVM shutdown
• First implementation of drawtext filter
• Most support classes now return the instance when calling setXY() methods

• Added support to extract an image in a specified file
• Screen Extractor now allows to extract images in original video size

• Change of logging api to slf4j as logging facade in version 1.7.x
• The encode methods now accept a List<> of MultimediaObject's, which are the concatenated
• Implemented set thread cound for encoding / decoding stages (Max number of cores/cpus to use)
• URL's as source are now treated as "multiple time readables" per default, can be overriden in the MultimediaObject
• Progress listener now works for URL's too, unless the "multiple time readables" flag is set to true

• Renamed native folder where the executables are to nativebin too, to prevent Java 9+ problems
• Allow to create a MultimediaObject with an URL instead of a file as conversion source
• Enhanced logging when ffmpeg executable could not be found in resources
• Make getFFMPEGExecutablePath() public to see what executable is beeing used
• Use alternative way to locate executables in jar file for Java 9+

• Renamed build artifacts with native in the name to nativebin to avoid module conflicts in Java 9+
  You will have to change your build dependencies if you did selectively include platforms

• Upgraded maven build infrastructure
• Upgraded windows and osx binaries to 4.1.3 from https://ffmpeg.zeranoe.com/builds/
• Upgraded linux binaries to 4.1.3 from https://johnvansickle.com/ffmpeg/

• Corrected win32 executable name, thanks to WavyPeng
• The bitrate was returned in kBps instead of Bps
• The channel detection did only work for mono+stereo, but not for quad (It does still not work for others)
• Added javadoc about volume and quality values

Added video and audio quality flags for conversion (see VideoAttributes.quality and AudioAttributes.quality)
Changed aac de/encoder from libvo_aacenc to default aac settings from ffmpeg
Upgraded windows and osx binaries to 4.1 from https://ffmpeg.zeranoe.com/builds/
Upgraded linux binaries to 4.1 from https://johnvansickle.com/ffmpeg/

• More informative error message when not finding ffmpeg executable
• Added option to copy over meta data if possible (setMapMetaData(true) in EncodingAttributes)
• Better handling of process exist code
