Issue about "--temporary-dir"

[08jingles]

I'm thinking since the --temporary-dir option specifies the working directory, shouldn't it default to completing muxing in this location before moving to the output directory? Additionally, os.rename will cause Invalid cross-device link (when I'm using rclone mount) (and this will also cause merging issue if muxing is doing in the output directory), so I'm wondering if it can be modified.

Regarding os.rename, I temporarily change it to as follows, which barely runs normally.

func TryMove(srcFile, dstFile string) error {
	// Open the source file for reading
	src, err := os.Open(srcFile)
	if err != nil {
		return err
	}
	defer src.Close()

	// Create the destination file
	dst, err := os.Create(dstFile)
	if err != nil {
		return err
	}
	defer dst.Close()

	// Copy the contents of the source file to the destination file
	_, err = io.Copy(dst, src)
	if err != nil {
		return err
	}

	// Close the destination file
	if err := dst.Close(); err != nil {
		return err
	}

	// Remove the source file
	if err := os.Remove(srcFile); err != nil {
		return err
	}

	return nil
}

But a lot of log info is missing

In between, there's a gap that missing something like

2024/04/25 21:10:42 INFO: Moving file /home/user/ytarchive-cache/QPULkVHVCic__3028340527/[QPULkVHVCic].f140.ts to /home/user/mount/rieru/[QPULkVHVCic].f140.ts

Also, this part clearly has something wrong
