Examples of com.xuggle.xuggler.IStreamCoder.open()

com.xuggle.xuggler.IStreamCoder.open()
Open the Codec associated with this StreamCoder. You can get the codec through getCodec(...) and set it with setCodec(...). You cannot call any set* methods after you've called open() on this StreamCoder until you close() it. You must call close() when you're done, but if you don't, the container will clean up after you (but yell at you) when it is closed. @return >= 0 on success; < 0 on error.

      ICodec.Type type = coder.getCodecType();
      if (!coder.isOpen() && isSupportedCodecType(type))
      {
        // open the coder


        int rv = coder.open();

          throw new RuntimeException("could not open stream " + stream + ": "
              + getErrorMessage(rv));
        mOpenedStreams.add(stream);
