我使用UDP连接,我有一个Android应用程序,它发送视频到运行Java应用程序的PC。 java应用程序运行在pc接收由android应用程序发送的数据包作为ByteArrayInputStream(imageData),现在我需要将这些图像转换为视频剪辑我该怎么做,以下是我的代码 java应用程序pc代码..
import java.io.ByteArrayInputStream;
import java.io.IOException;

import java.lang.Thread;

public static int DATA_MAX_SIZE = DATAGRAM_MAX_SIZE - HEADER_SIZE;

{
car_state = gui;
try
{
t = new Thread(this);
t.start();
}
catch (Exception e){e.printStackTrace();}
}

handleConnection_UDP();
}

byte[] buffer = new byte[DATAGRAM_MAX_SIZE];
DatagramPacket packet = new DatagramPacket(buffer, buffer.length);
while (true)

byte[] data = packet.getData();
int frame_nb = (int)data[0];
int nb_packets = (int)data[1];

if((packet_nb==0) && (current_frame != frame_nb))
{
current_frame = frame_nb;

imageData = new byte[nb_packets * DATA_MAX_SIZE];
}
if(frame_nb == current_frame)
{
System.arraycopy(data, HEADER_SIZE, imageData, packet_nb * DATA_MAX_SIZE, size_packet);
slicesStored++;
}
/* If image is complete display it */
if (slicesStored == nb_packets)
{
ByteArrayInputStream bis = new ByteArrayInputStream(imageData);
car_state.set_image(bis);
}
}
} catch (IOException e)
