Free MP4 to MP3 Converter - Changelog:
- 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.
