I'm trying to get MP3 Metadata without downloading an entire MP3.
I've setup a FilterInputStream which throws an InterruptedIOException after a
given amount of a file is downloaded.
If I point this at an HTML page it works - I can get the title from the
metadata.
If I point it at an MP3 file it doesn't give me any metadata at all (except the
Metadata.RESOURCE_NAME_KEY which I set), even if I set the download length to
be just less than the length of the file. If I download the whole file it works
(JPGs don't seem to work either)
Why is this so? My understanding was that Tika would work with streams?
Code:
CountingInputStream stream = new
CountingInputStream(method.getResponseBodyAsStream(), new CountingListener() {
public void transferred(long amount, InputStream
theStream) throws InterruptedIOException {
if (amount > 20000l) {
throw new InterruptedIOException();
}
}
});
Metadata metadata = new Metadata();
metadata.set(Metadata.RESOURCE_NAME_KEY, address);
try {
parser.parse(stream, getXmlContentHandler(), metadata);
} catch (Exception e) {
e.printStackTrace();
} finally {
System.out.println("size = " + stream.getTransferred());
stream.close();
}
System.out.println(Arrays.toString(metadata.names()));
