这可能是由于代码中对位域的使用不正确导致的。位域的行为是由编译器实现定义的,不同的编译器可能会有不同的行为。因此,在代码中使用位域时需要小心,确保其行为是可预测的。在这种情况下,可能需要检查代码中的位域定义和使用是否正确,以确保其在不同的编译器中都能正常工作。此外,还需要检查是否有其他代码修改了相关的变量,在不同的文件中可能会存在不同的变量定义,导致赋值失败。

这段代码是 C++ 语言中的一个结构体定义,结构体名为 MsgCommonInfo,其中包含了多个成员变量,如 mme_ue_s1ap_id、mme_ip、mme_port、enb_ue_s1ap_id、enb_ip、enb_port 等等。这些成员变量记录了通信过程中的一些常用信息,如通信双方的 IP 地址、端口号、设备 ID 等,以及一些与通信相关的参数,如用户的最大上下行带宽、加密信息等。结构体中还定义了一个 Reset() 函数,用于将结构体中的成员变量清零。代码中还有一些注释,说明了这些成员变量的含义和用途。
typedef struct _NDI_AUDIO_STREAM_S{ int bit_rate; int no_samples; int sample_rate; int channels; int size; int type; unsigned char *stream[4]; uint64_t pts; uint64_t dts; uint32_t extra_size; uint32_t extradata; }NDI_AUDIO_STREAM_S;
这段代码定义了一个名为 `NDI_AUDIO_STREAM_S` 的结构体,表示一个 NDI 音频流。其中,成员变量包括:
- `bit_rate`:音频比特率
- `no_samples`:一个音频帧中的采样点数
- `sample_rate`:采样率
- `channels`:声道数
- `size`:音频数据的字节数
- `type`:音频编码类型
- `stream`:指向音频数据的指针数组,最多包含 4 个指针
- `pts`:音频帧的显示时间戳
- `dts`:音频帧的解码时间戳
- `extra_size`:音频附加数据的字节数
- `extradata`:指向音频附加数据的指针
需要注意的是,这个结构体与 ALSA 框架没有直接的关系,而是用于表示 NDI 音频数据的结构体。
