I am creating a Java based GUI for the Windows exe version of youtube-dl .
The OUTPUT TEMPLATE portion of the README says that -o can be used to set the save location and file name while downloading.
When I use the program through command line, I can set the download location as normal using youtube-dl.exe -o "C:\Users\<user>\Videos\%(title)s.%(ext)s" <youtube-link> and it downloads as normal to the specified folder.
However, when I am calling the process through Java, using ProcessBuilder as follows:
output = "-o \"" + save_path + "\\%(title)s.%(ext)s\"";
Process process = new ProcessBuilder("lib\\youtube-dl.exe", output, url.getText()).start();
I keep getting the following output:
-o "C:\Users\nightstalker\Videos\youtube-dl\%(title)s.%(ext)s"

[download] Destination: C#\Users\nightstalker\Videos\youtube-dl\Some Video.mp4
This is what save_path looks like
File save_path = new File("C:\\Users\\"+System.getProperty("user.name")+"\\Videos\\youtube-dl");
This basically creates a folder called C#\Users\nightstalker\Videos\youtube-dl and continues to download there.
Any reason why?
I'm going to sidestep the formatting problem and hopefully provide an answer that still works for you.
ProcessBuilder lets you set the working directory as follows:
Process p = null; ProcessBuilder pb = new ProcessBuilder("do_foo.sh"); pb.directory("/home"); p = pb.start();
Instead of putting the whole path into the -o option passed to youtube-dl you can set the directory() on the ProcessBuilder to **C:\Users\<user>\Videos** as follows:
output = "\"%(title)s.%(ext)s\"";
Process process = new ProcessBuilder("lib\\youtube-dl.exe", "-o", output, url.getText()).directory("save_path").start();
