一些簡單的東西,自己匯總了下,其他的都太雜了,如有侵權請告知。
文件視頻的讀寫:
public static void main(String[] args) {
BufferedInputStream reader;
BufferedOutputStream writer;
try{
reader=new BufferedInputStream(new FileInputStream("路徑"));
writer=new BufferedOutputStream(new FileOutputStream("路徑"));
int s;
while((s=reader.read())!=-1){
writer.write(s);
writer.flush();
}
writer.close();
reader.close();
}catch(IOException e){
System.out.print("文件讀寫錯誤");
}
}
視頻大小:
private static String ReadVideoSize(File source) {
FileChannel fc= null;
String size = "";
try {
@SuppressWarnings("resource")
FileInputStream fis = new FileInputStream(source);
fc= fis.getChannel();
BigDecimal fileSize = new BigDecimal(fc.size());
size = fileSize.divide(new BigDecimal(1048576), 2, RoundingMode.HALF_UP) + "MB";
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (null!=fc){
try{
fc.close();
}catch(IOException e){
e.printStackTrace();
}
}
}
return size;
}
獲取時長
private static String ReadVideoTime(File source) {
Encoder encoder = new Encoder();
String length = "";
try {
MultimediaInfo m = encoder.getInfo(source);
long ls = m.getDuration()/1000;
int hour = (int) (ls/3600);
int minute = (int) (ls%3600)/60;
int second = (int) (ls-hour*3600-minute*60);
length = hour+"小時"+minute+"分鍾"+second+"秒";
} catch (Exception e) {
e.printStackTrace();
}
return length;
}
然后自己寫個main方法就能運行了
public static void main(String[] args) {
File a = new File("G:\\1.mp4");
String size = ReadVideoSize(a);
String time = ReadVideoTime(a);
System.out.println(size);
System.out.println(time);
}
