Question

您好我想将我的视频文件上传到Android中的网络服务器。我遵循了这个教程：

Uploading files to HTTP server using POST on Android.

但是。我的logcat中出现了这个错误。我也收到了来自服务器的消息。

按照此过程我想将视频文件上传到wowza媒体服务器。我该如何解决这个问题。我怎样才能进入wowza服务器？任何人都可以帮我实现这个目标吗？提前谢谢。

从byte []向服务器发送视频可能会导致outOfMemoryError，因此最好从MultiPart发布视频。您可以从此链接下载jar文件。 http://hc.apache.org/downloads.cgi。下载并将httpmime-4.2.jar添加到您的项目中。

public void uploadVideo(Context context, String videoPath) {
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost postRequest = new HttpPost(context.getString(R.string.url_service_fbpost));
            MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
            if(!videoPath.isEmpty()){

                FileBody filebodyVideo = new FileBody(new File(videoPath));
                reqEntity.addPart("uploaded", filebodyVideo);
            }
            postRequest.setEntity(reqEntity);
            HttpResponse response = httpClient.execute(postRequest);

            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    response.getEntity().getContent(), "UTF-8"));
            String sResponse;
            StringBuilder s = new StringBuilder();

            while ((sResponse = reader.readLine()) != null) {
                s = s.append(sResponse);
            }

            Log.e("Response: ", s.toString());
            return true;

        } catch (Exception e) {
            Log.e(e.getClass().getName(), e.getMessage());
            return false;
        }
}

这只是因为视频的大小。对大文件/视频使用块上传方法。

以下是在服务器上发布块数据的示例代码。

public void upload(String filename, byte[] image) {
     // 1MB of chunk
    byte[][] divideByte = divideArray(image, ((1024 * 1024)/2));
    int length = divideByte.length;
    String token = "" + (int)System.currentTimeMillis();
    Log.i("System out", "divideByte:" + length);
    Log.i("System out", "token:" + token);

    for (int i = 0; i < length; i++) {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

        String link = "<your link>";

        nameValuePairs.add(new BasicNameValuePair("filename", filename));// filename
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(link);
        Log.i("System out", "divideByte[" + i + "] length :"
                + divideByte[i].length);
        String img = Base64.encodeBytes(divideByte[i]);
        nameValuePairs.add(new BasicNameValuePair("file64", img));

        nameValuePairs.add(new BasicNameValuePair("token", new String(""
                + token)));
        nameValuePairs.add(new BasicNameValuePair("chunksize", new String(""+
                divideByte[i].length)));
        nameValuePairs.add(new BasicNameValuePair("chunkcount", new String(
                "" + length)));
        nameValuePairs.add(new BasicNameValuePair("index", new String(""
                + i)));
        try {
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity httpEntity = response.getEntity();
            if (httpEntity != null) {
                String res = EntityUtils.toString(httpEntity).toString();
                Log.i("System out", "response is :" + res);                 
            }
            httpEntity = null;
            response = null;
        } catch (Exception e) {
            e.printStackTrace();
        }finally{
            httppost = null;
            httpclient = null;
        }           
    }
}

public static byte[][] divideArray(byte[] source, int chucksize) {

    byte[][] ret = new byte[(int) Math.ceil(source.length
            / (double) chucksize)][chucksize];

    Log.i("System out","ret: "+ret.length);
    int start = 0;

    for (int i = 0; i < ret.length; i++) {
        if (start + chucksize > source.length) {
            System.arraycopy(source, start, ret[i], 0, source.length
                    - start);
        } else {
            System.arraycopy(source, start, ret[i], 0, chucksize);
        }

        start += chucksize;
    }

    return ret;
}

并在服务器端获取所有块索引并组成一个视频文件。

希望能帮到你。
