求帮助:这个SDK文件下加个回声抑制算法,目前状况是开发了一款视频通话软件,通过机顶盒,机顶盒是安卓5.0系统。环境是,机顶盒通过usb口驱采集动连接一体的麦克风和摄像头采集声音和图像,然后由电视机播出。 可能原因是以前都用专业的硬件降噪处理,软件的降噪没有写。或者是因为机顶盒采集,电视播出声音算法不是作用在同一机器上导致的问题。求大神帮忙二次封装sdk或者什么别的方法在SDK库下处理,或者能提供好的方案,最好接口什么不要改变,在线等急急急!!!!!谢谢

<div class="post-text" itemprop="text"> <p>so I just created my first website and I'm using php file to communicate with my android app.. The android app is requesting for alot of data and the php is sending it back to it.</p> <p>The only way I have found yet to send data from php to the android is via <code>echo</code></p> <p>I have alot of strings and pictures in my data and I seperate them all with ugly <code>"BUFFER1"</code> style buffers between each data as it all comes out eventually as a long string combined together..</p> <p>Here is an example:</p> <pre><code>&lt;?php $input_number = $_POST["In_Number"]; $path = ("Folder/" . $input_number); $Data1 = file_get_contents($path . "/data1.txt"); $Data2 = file_get_contents($path . "/data2.txt"); $Data3 = file_get_contents($path . "/data3.txt"); echo $Data1; echo "STREAMING_BUFFER"; echo $Data2; echo "STREAMING_BUFFER"; echo $Data3; echo "STREAMING_BUFFER"; ... // sending the pictures now (encoded..) $pic_folder_path = ("Folder/" . $input_number . "/pics/"); $pics_pathes = array_diff(scandir($pic_folder_path), array('..', '.')); foreach($pics_pathes as $pic_path){ $image = file_get_contents($pic_folder_path . $pic_path); echo base64_encode($image); echo "PICTURE_BUFFER"; } echo "STREAMING_BUFFER"; // END ?&gt; </code></pre> <p>The android to php communicate is much simpler.. I use the <code>POST</code> method to send <code>&lt;key,value&gt;</code> pairs and I can easily read them that way..</p> <pre><code>&lt;?php $name = $_POST["name"]; $image = $_POST["image"]; $decodedImage = base64_decode("$image"); file_put_contents("pictures/" . $name . ".JPG", $decodedImage); ?&gt; </code></pre> <p>The <code>name</code> is easily separated from the <code>image</code> data.. and sure I could seperate that way much more data</p> <p>Is there any similar way for the php to android way?</p> <p>Thanks.</p> </div>

Problem Description There are many gods and devils living on HDU Island, and echo is one of them. Gods always tell the truth whereas devils sometimes tell the truth but sometimes not. What's more, every god and devil knows all the others are a god or a devil. One day, an accident unfortunately happened which made echo lose her memory. She was so despairing and determined to turn to others for help. She asked all the residents a question, but all of the answers were merely "Be careful! X is a devil!". As a result she failed to arouse her memory. However, she has to find out a method to calculate the minimum number of devils on the island. Could you help echo to manage it well? Input There are multi-cases (The total number of cases won't exceed 20). First line is an integer N(1<=N<=15000), the total number of gods and devils. Then N lines follow, each line includes a name, and the length of each name won't exceed 30. The first name is "echo". The next N-1 lines will be as the formation "A says: Be careful! B is a devil!"(A is different from B), and you can assume that at least one of them will consider echo is a devil and says "Be careful! echo is a devil!". Output Output the minimum number of devils in the island. Sample Input 3 echo bigdog smalldog smalldog says: Be careful! bigdog is a devil! bigdog says: Be careful! echo is a devil! 4 echo Lethe bigdog smalldog Lethe says: Be careful! bigdog is a devil! smalldog says: Be careful! echo is a devil! bigdog says: Be careful! smalldog is a devil! Sample Output 1 2
