dm3730 同时打开两个相同的codec实例出错

我的目的是想在不同的线程中同时解两路h264码流，看了codec engine相关文档，是支持该操作的。

Codec Engine Application Developer User's Guide 第4.3.6节，同时打开了两个相同的codec，但是其优先级不一样。

Engine_Handle ce;
    AUDENC_Handle enc;
    AUDENC_Handle enc_high;
    ce = Engine_open("audio_copy", NULL, NULL);
    /* Create codec at the configured priority */
    enc = AUDENC_create(ce, "audenc_copy", NULL);
    /* Create second instance of codec, overriding the
     * configured priority with a priority of 5 */
    enc_high = AUDENC_create(ce, "audenc_copy:5", NULL) ;

我写了一个测试代码，在两个不同的线程中打开相同的codec，却出错：

程序main.c和*cfg文件请见附件。

请大家帮忙看下这个问题，谢谢！

已经解决了，主要是修改内存分配。请参考下面这个

楼主你好。

我现在使用的是Devkit8500.他的内存是512MB的，我现在加载cmem时。出现的串口信息是这样的。

CMEMK module: built on Oct 14 2010 at 13:14:41

但是，在运行codec engine时却出现了如下的错误。

我查看了http://processors.wiki.ti.com/index.php/Changing_the_DVEVM_memory_map上面的介绍。里面说到，codec-engine的最大寻址空间是256M的。现在我很迷茫。不知如何解决。请问楼主能给些意见么？

谢谢了
