Voglio riprodurre in streaming il video ed è in formato m3u8. Così ho provato il codice qui sottoRiproduzione video m3u8 in android
public class StreamingPlayer extends Activity implements
OnBufferingUpdateListener, OnCompletionListener,
OnPreparedListener, OnVideoSizeChangedListener, SurfaceHolder.Callback{
private static final String TAG = StreamingPlayer.class.getSimpleName();
private int mVideoWidth;
private int mVideoHeight;
private MediaPlayer mMediaPlayer;
private SurfaceView mPreview;
private SurfaceHolder holder;
private String path;
private boolean mIsVideoSizeKnown = false;
private boolean mIsVideoReadyToBePlayed = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.mediaplayer_2);
mPreview = (SurfaceView) findViewById(R.id.surface);
holder = mPreview.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
private void playVideo() {
doCleanUp();
try {
/*
* TODO: Set path variable to progressive streamable mp4 or
* 3gpp format URL. Http protocol should be used.
* Mediaplayer can only play "progressive streamable
* contents" which basically means: 1. the movie atom has to
* precede all the media data atoms. 2. The clip has to be
* reasonably interleaved.

path = "httplive://xboodangx.api.channel.livestream.com/3.0/playlist.m3u8";
if (path == "") {
// Tell the user to provide a media file URL.
Toast

this,

In logcat mostra onBufferingUpdate percent:100 ma non riesco a vedere il video.
L'audio funziona ma improvvisamente è stato colpito.
E ho provato questo collegamento video http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8 sta funzionando. Ma il mio collegamento video non funziona e ho cambiato httplive://... instead of http:// ma non uso.
E ho visto questa risposta anche Android video stream mms and m3u8.
Nel collegamento sopra mostra Il messaggio video non può essere riprodotto.
Hai provato a testarlo su un dispositivo reale? a volte l'emulatore fa schifo quando si tratta di HTTP Live Streaming. – yorkw
@yorkw Grazie per la vostra risposta. Sì ho provato nel dispositivo reale non in emulatore. – Ramakrishna
L'URI h t t p: //myvideo.m3u8 mi sembra strano, dove ospiterai i media? un server remoto? Se hai accesso al codice di trasmissione sul lato server, prova a cambiarlo in un URL più solido come h t t p: //dominio-nome/servizio-nome/myvideo.m3u8. Non sono sicuro se questo lavoro, ma vale la pena di provare. – yorkw
