Error convert video to mp3, closing bracket at the end of the resulting file's name
Posted: 10 Nov 2020 08:45
Hi.
I have created a Powershell script to help me extract the audio of a video file and output it to a mp3 file. The script worked but there is problem. The resulting output file has a closing bracket at the end of the file's name, that is the file's name is not "example_output_file.mp3" but "example_output_file.mp3}". I hope somebody can give the help.
Here is the script:
Thanks.
