Sorry in advance as I'm new to linux. OS "Ubuntu 12-04-AutogenByAWSMP"
From my servlet I wish to launch ffprobe to learn info about a movie file.
From the command line this works fine. From within java this always fails with: (from error stream)
/usr/bin/ffprobe: /opt/bitnami/common/lib/libstdc++.so.6: versionGLIBCXX_3.4.11' not found (required by /usr/lib/x86_64-linux-gnu/libjack.so.0) /usr/bin/ffprobe: /opt/bitnami/common/lib/libstdc++.so.6: version
GLIBCXX_3.4.9' not found (required by /usr/lib/x86_64-linux-gnu/libjack.so.0) /usr/bin/ffprobe: /opt/bitnami/common/lib/libstdc++.so.6: versionGLIBCXX_3.4.15' not found (required by /usr/lib/x86_64-linux-gnu/libjack.so.0) /usr/bin/ffprobe: /opt/bitnami/common/lib/libstdc++.so.6: version
GLIBCXX_3.4.9' not found (required by /usr/lib/libopencv_core.so.2.3)
My java code is:
private static String PATH_FOR_ENV = "=/opt/bitnami/sqlite/bin:/opt/bitnami/java/bin:/opt/bitnami/php/bin:/opt/bitnami/mysql/bin:/opt/bitnami/apache2/bin:/opt/bitnami/common/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games";
.....
final ProcessBuilder builder = new ProcessBuilder();
builder.redirectErrorStream(true);
List<String> params = createCommand("ffprobe");
this.addFFProbeArgs(params);
params.add(src.getAbsolutePath());
ProcessBuilder command = builder.command(params);
if(isLinux())
command.environment().put("LIBPATH", PATH_FOR_ENV);
Process p= command.start();
InputStream input = p.getInputStream();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
byte[] bytes = new byte[1024];
int read;
while ((read = input.read(bytes)) != -1)
{
bos.write(bytes, 0, read);
}
input.close();
p.waitFor();
String info = new String(bos.toByteArray());
System.out.println(info);
Additional helpers
private void addFFProbeArgs(List<String> pParams)
{
pParams.add("-v");
pParams.add("quiet");
pParams.add("-show_streams");
pParams.add("-show_format");
pParams.add("json");
}
private List<String> createCommand(String pCommand)
{
List<String> commandParams = new ArrayList<String>();
if(isLinux())
{
//commandParams.add("/bin/bash");
//commandParams.add("-c");
}
commandParams.add(ROOT_DIR+ pCommand);
return commandParams;
}
private static String ROOT_DIR = "/usr/bin/";
I know the codes not pretty (been limping along while I try and figure out the problem). I have doing lots of googling and lots of reading (including many on this site). You can see things I tried that I commented out, eg putting /bin/bash -c in front of ffprobe. Also I'm currently setting the LIBPATH to be the same as the PATH that works when I'm at the prompt (grasping @ straws).
Any thoughts? Thanks in advance.
