ffmpeg 꽤 아주 좋은 오픈 소스 자산 및 자원을 안전하게 가지고 좋은 라이브러리 주셔서 감사합니다. ffmpeg라는 작업을 수행이 스크립트 (pars_submit)에
@Path("/ffmpeg")
public class FfmpegResource {
@GET
@Produces("text/plain")
public String getFfmpeg(@QueryParam("infil1") String infil1,
@QueryParam("infil2") String infil2, @QueryParam("otfil") String otfil,
@QueryParam("t") String time) {
String outfil = "dummy.mp4";
List<String> command = new ArrayList<String>();
command.add("vendor/bin/pars_submit");
command.add(infil1);
command.add(infil2);
command.add(otfil);
command.add(time);
System.out.println("Starting process " +command.toString());
ProcessBuilder builder = new ProcessBuilder(command);
Map<String, String> environ = builder.environment();
Process process = null;
try {
process = builder.start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null) {
outfil=line;
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally {
if (process != null) {
process.destroy();
process = null; // int exitVal = process.waitFor();
// System.out.println("Process exitValue: " + exitVal);
}
}
return outfil;
}
}

나는 그것을 실제는 FFmpeg은이 과정에 의해 호출되는 자바 (JAX-RS) REST API의 서버 측을 사용합니다 :
