Error loading local image when adding a watermark using FFmpegFrameFilter.

[XLXNG]

The code is as follows:

    String watermarkImagePath = "E:/watermark/watermark.png";
    String filterStr = String.format("[in]scale=1920:1080[v1];movie=%s[watermark];[v1][watermark]overlay=0:0,format=rgba [out]",watermarkImagePath);
    FFmpegFrameFilter filter = new FFmpegFrameFilter(filterStr, 1920, 1080);
    filter.start();

When I change watermakImagePath to a file under the project, String watermarkImagePath = "watermark.png", the watermark can be generated normally，I use an absolute path,watermarkImagePath = "E:/watermark/watermark.png", it gives an error.
