ich meine eigene MediaDataSource haben:
MediaExtractor nicht versteht Audio/AACP Streams
class MyDataSource extends MediaDataSource {
private static final String TAG = "MyDataSource";
private HttpURLConnection connection;
private BufferedInputStream inputStream;
MyDataSource(@NonNull URL streamURL) throws Throwable {
this.connection = (HttpURLConnection) streamURL.openConnection();
this.connection.setRequestMethod("GET");
this.connection.addRequestProperty("Icy-Metadata", "0");
this.connection.connect();
int responseCode = this.connection.getResponseCode();
if (responseCode != 200)
throw new IOException("http response code " + responseCode);
for (Map.Entry<String, List<String>> header: this.connection.getHeaderFields().entrySet()) {
for (String headerValue : header.getValue())
Log.v(TAG, "responseHeader(" + header.getKey() + ") = \"" + headerValue + "\"");
}
this.inputStream = new BufferedInputStream(connection.getInputStream());
}
@Override
public long getSize() {
return -1;
}
@Override
public int readAt(long position, @NonNull byte[] buffer, int offset, int size) throws IOException {
int bytesRead;
int bytesReadTotal = 0;
do {
bytesRead = this.inputStream.read(buffer, offset + bytesReadTotal, size - bytesReadTotal);
bytesReadTotal += bytesRead;
} while(bytesRead != 0 && bytesReadTotal < size);
return bytesReadTotal;
}
@Override
public void close() {
try {
if (inputStream != null) {
inputStream.close();
inputStream = null;
}
if (connection != null) {
connection.disconnect();
connection = null;
}
} catch(IOException e) {
Log.e(TAG, "close", e);
}
}
}
Und wenn ich versuche, MP3 Stream zu spielen (ex A.0.0.00Radio.):
MyDataSource dataSource = new MyDataSource(new URL("http://streaming.shoutcast.com/80sPlanet"));
MediaExtractor mediaExtractor = new MediaExtractor();
mediaExtractor.setDataSource();
MediaFormat mediaFormat = mediaExtractor.getTrackFormat(0);
String mime = mediaFormat.getString(MediaFormat.KEY_MIME);
Log.v("Player", "mime: " + mime);
mediaExtractor.selectTrack(0);
MediaCodec mediaCodec = MediaCodec.createDecoderByType(mime);
mediaCodec.configure(this.mediaFormat, null, null, 0);
int sampleRate = mediaFormat.getInteger(MediaFormat.KEY_SAMPLE_RATE);
AudioTrack audioTrack = new AudioTrack(
AudioManager.STREAM_MUSIC,
sampleRate,
AudioFormat.CHANNEL_OUT_STEREO,
AudioFormat.ENCODING_PCM_16BIT,
AudioTrack.getMinBufferSize(sampleRate, AudioFormat.CHANNEL_OUT_STEREO, AudioFormat.ENCODING_PCM_16BIT),
AudioTrack.MODE_STREAM);
mediaCodec.setCallback(new MyCodecCallback());
mediaCodec.start();
audioTrack.play();
I siehe die folgenden Logcat trace:

Es scheint, dass alles in Ordnung ist (der Stream spielt tatsächlich durch das Gerät).

Weiß jemand, was ist das Problem:
MyDataSource dataSource = new MyDataSource(new URL("http://111.223.51.8:8005"));
[...]
die MediaExtractor verrückt wird? Das Problem ist definitiv nicht im Stream selbst - es ist voll gültig.
