Question

当我关闭IMediaWriter时，我一直遇到异常简单的转码。例外是“java.lang.RuntimeException：错误操作不是允许，未能将预告片写入test.mp3“ 每当我调用IMediaWriter.close（）时，我都会得到这个，任何想法为什么我会得到这个简单的转码？这是示例代码：

IMediaReader reader = null; 
    IMediaWriter writer = null; 
    try { 
        reader = ToolFactory.makeReader("test.wav"); 
        writer = ToolFactory.makeWriter("test.mp3", reader); 
        reader.addListener(writer); 
        while (reader.readPacket() == null) ; 
        reader.close(); 
        writer.close(); 
    } catch (Exception ex) { 
        ex.printStackTrace(); 
    }

这肯定会起作用，因为我遇到了同样的问题。谢谢。如果您想要更多说明，请询问......

IMediaReader reader = null; 
    IMediaWriter writer = null; 
    try { 
        reader = ToolFactory.makeReader("sijo.mp4"); 
        writer = ToolFactory.makeWriter("Thomas.flv", reader); 
        reader.addListener(writer); 
        while (reader.readPacket() == null) ; 
        //Should IMediaReader automatically call close(), only if ERROR_EOF (End of File) is returned from readPacket().
        reader.setCloseOnEofOnly(false); 
        //If false the media data will be left in the order in which it is presented to the IMediaWriter.
        //If true IMediaWriter will buffer media data in time stamp order, and only write out data when it has at least one same time or later packet from all streams.
        writer.setForceInterleave(false);
        System.out.println("closed...");
    } catch (Exception ex) { 
        ex.printStackTrace(); 
    }
