Examples of com.xuggle.xuggler.IContainer.queryStreamMetaData()

com.xuggle.xuggler.IContainer.queryStreamMetaData()

Attempts to read all the meta data in this stream, potentially by reading ahead and decoding packets.

Any packets this method reads ahead will be cached and correctly returned when you read packets, but this method can be non-blocking potentially until end of container to get all meta data. Take care when you call it.

After this method is called, other meta data methods like {@link #getDuration()} should work.

If the current thread is interrupted while this blocking method is running the method will return with a negative value. To check if the method exited because of an interruption pass the return value to {@link IError#make(int)} and then check {@link IError#getType()} to see if it is {@link IError.Type#ERROR_INTERRUPTED}.

@return >= 0 on success; <0 on failure.

    int retval = -1;
    
    retval = container.open(mSampleFile, IContainer.Type.READ, null);
    assertTrue("could not open file", retval >= 0);
    
    retval = container.queryStreamMetaData();
    assertTrue("could not query stream meta data", retval >= 0);
    
  }


  @Test

  {
    IContainer container = IContainer.make();
    
    int retval = -1;
    
    retval = container.queryStreamMetaData();
    assertTrue("could query stream meta data", retval < 0);
    
  }
