    <p>I am using MediaCodec low level Api in android to decode h264 raw stream received from IP CAMERA. Raw stream from IP camera , receiving on TCP/IP connection.</p> <p>To decode stream , My code is :</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { MediaCodec mCodecc; MediaFormat mFormat; BufferInfo mInfo; ByteBuffer[] inputBuffers ; ByteBuffer[] outputBuffers ; } protected void Init_Codec() { mCodecc = MediaCodec.createDecoderByType("video/avc"); mFormat = MediaFormat.createVideoFormat("video/avc", width, height); mInfo = new BufferInfo(); mFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT,MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Planar); mCodecc.configure(mFormat, holder.getSurface(), null,0); } protected void Start_Codec() { mCodecc.start(); inputBuffers = mCodecc.getInputBuffers(); outputBuffers = mCodecc.getOutputBuffers(); } private void OnRawStreamReceived(final ByteBuffer buffer) { mHandler.postAtFrontOfQueue(new Runnable() { @Override public void run() { int inIndex = mCodecc.dequeueInputBuffer(10000); if(inIndex&gt;=0) { inputBuffers[inIndex] = buffer; mCodecc.queueInputBuffer(inIndex, 0,buffer.limit(),System.currentTimeMillis(), 0); } int outIndex = mCodecc.dequeueOutputBuffer(mInfo, 10000); switch (outIndex) { case MediaCodec.INFO_OUTPUT_BUFFERS_CHANGED: Log.d("DecodeActivity", "INFO_OUTPUT_BUFFERS_CHANGED"); outputBuffers = mCodecc.getOutputBuffers(); break; case MediaCodec.INFO_OUTPUT_FORMAT_CHANGED: Log.d("DecodeActivity", "New format " + mCodecc.getOutputFormat()); break; case MediaCodec.INFO_TRY_AGAIN_LATER: Log.d("DecodeActivity", "dequeueOutputBuffer timed out! --- size : " + mInfo.size ); break; default: ByteBuffer buffer = outputBuffers[outIndex]; mCodecc.releaseOutputBuffer(outIndex, true); break; } } int outIndex = mCodecc.dequeueOutputBuffer(mInfo, 10000); </code></pre> <p>But at this line of code , I'm always receiving "-1". and mInfo.size() is also I'm getting "0". and It is not displaying anything on given surface.</p> <p>Which step I'm missing. please guide me. thanx</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
