java - Regarding video and audio stream over socket.io from android camera live -


i want stream real time video android camera device via socket.io, not able send audio

as using surfaceview create camra view

on camera preview getting video bytes

but bytes not contain audio, contain video frame

help me how can merge video , audio @ same time byte array , send other device, while recording , on other side how can decode

code using 

 mcamera.setpreviewcallbackwithbuffer(new camera.previewcallback() {              private long timestamp = 0;              public synchronized void onpreviewframe(byte[] data, camera camera) {                  int size = data.length;                 camera.size previewsize = camera.getparameters().getpreviewsize();                 yuvimage yuvimage = new yuvimage(data, imageformat.nv21, previewsize.width, previewsize.height, null);                 bytearrayoutputstream baos = new bytearrayoutputstream();                 yuvimage.compresstojpeg(new rect(0, 0, previewsize.width, previewsize.height), 80, baos); //                yuvimage.compresstojpeg(new rect(0, 0, 128, 96), 80, baos);                 byte[] jdata = baos.tobytearray(); //                int sizeofdata = jdata.length;                  datagramsocket s;                 try {                     s = new datagramsocket();                     s.setbroadcast(true);                     s.setsotimeout(timeout_ms);                     inetaddress local = inetaddress.getbyname(ipadresse.gettext().tostring());                      datagrampacket p = new datagrampacket(jdata, jdata.length, local, server_port);                     s.send(p);                  } catch (socketexception e) {                     e.printstacktrace();                 } catch (unknownhostexception e) {                     e.printstacktrace();                 } catch (ioexception e) {                     e.printstacktrace();                 }  //                // convert bitmap                 bitmap bmp = bitmapfactory.decodebytearray(jdata, 0, jdata.length);                 m_videcapturebitmap.setimagebitmap(bmp);                  log.v("cameratest", "frame size = " + data.length);                 timestamp = system.currenttimemillis();                 try {                     camera.addcallbackbuffer(data);                 } catch (exception e) {                     log.e("cameratest", "addcallbackbuffer error");                     return;                 }                 return;             }         });          try {             mcamera.startpreview();         } catch (throwable e) {             mcamera.release();             mcamera = null;             e.printstacktrace();             return;         }

you need desing/use protocol share 1 connection sending video&audio data, or can use connection (eg designated server port) audio only, you'll have 1 connection audio , video.

as how grab audio android mic byte array there's answer here: android record mic bytearray without saving audio file

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
