Pazera MP4 to MP3 Converter 1.7 + Portable + x64

Updated conversion engine (FFmpeg) and multimedia information library (MediaInfo).
Information about the conversion progress is displayed on the title bar of the main window and on the taskbar.
The metadata settings are now saved to the configuration file and restored the next time the program is started.
FFmpeg encoder parameters window (F2): information has been divided into groups displayed on separate lines, which facilitates parameter analysis.
Fixed Stack overflow bug when selecting next files in the list very quickly.
Added support for files from network shares whose names start with the characters \\.
When saving the report to a text file in the File properties window, UTF-8 encoding is used (in previous versions the system default code page was used).
After the user has interrupted the conversion, the program displays a window asking whether to delete the incompletely converted file. Such files usually have a damaged internal structure and cannot be played.
If incorrect parameters are passed to the conversion engine (FFmpeg) and the conversion process fails, the output file will be automatically deleted. Such a file usually does not contain any data (0 bytes in size) and only unnecessarily litter the disk.
Displaying additional information in the error log window.
UTF-8 encoding (instead of the system code page) is used when writing the error log to a text file.
Improved handling of user-created profiles.
Lots of minor changes and fixes to the source code and the program interface.

Updated conversion engine (FFmpeg) and multimedia information library (MediaInfo).
New MP3 encoder settings: stereo mode (L/R stereo, joint stereo), encoding algorithm quality, lowpass filter.

Changes in the information module:
For easier identification, video streams are now highlighted in red, audio - green, subtitles - purple, chapters (menu) - blue.
The window layout is now saved to the configuration file and restored the next time the program is started.
When turning on dark visual styles, the main window icons are slightly darkened to reduce the contrast.
New translation: Slovenian.
New About window displaying additional information.
