Dear All,
I am working on new project in which I need to access GPS location from MP4 video. Here is the code I tried, but getting Null Pointer Exception.
File videoFile = new File(videoFilePath);
if (!videoFile.exists()) {
throw new FileNotFoundException("File " + videoFilePath + " not exists");
}
if (!videoFile.canRead()) {
throw new IllegalStateException("No read permissions to file " + videoFilePath);
}
IsoFile isoFile = new IsoFile(videoFilePath);
AppleNameBox nam = Path.getPath(isoFile, "/moov[0]/udta[0]/meta[0]/ilst/©xyz");
String xml = nam.getValue();
Thanks,
Om
This code worked for me. It gives NPE, when no location tags are available.
private String readVideoLocation(String fullFilePath) throws Exception {
File videoFile = new File(fullFilePath);
if (!videoFile.exists()) {
throw new FileNotFoundException("File " + fullFilePath + " not exists");
}
if (!videoFile.canRead()) {
throw new IllegalStateException("No read permissions to file " + fullFilePath);
}
FileDataSourceImpl fileDataSource = new FileDataSourceImpl(fullFilePath);
IsoFile isoFile = new IsoFile(fileDataSource);
AppleGPSCoordinatesBox locBox = Path.getPath(isoFile, "/moov[0]/udta[0]/meta[0]/ilst/©xyz");
String xml = locBox.getValue();
isoFile.close();
return xml;
}
