H A Daudio-video-demuxer.md86 // 为自定义数据源创建 source 资源对象(可选)。使用该方式前，需要先实现AVSourceReadAt接口函数实现。
89 // OH_AVDataSource dataSource = {fileSize, AVSourceReadAt};
93 AVSourceReadAt接口函数，需要放在创建资源管理实例对象前实现：
108 int32_t AVSourceReadAt(OH_AVBuffer *data, int32_t length, int64_t pos)
111 printf("AVSourceReadAt : data is nullptr!\n");
117 printf("AVSourceReadAt : open file failed! file:%s\n", g_filePath.c_str());
124 printf("AVSourceReadAt : pos over or equals file size!\n");
134 printf("AVSourceReadAt : raed length less than zero!\n");

H A Daudio-video-demuxer.md86 …esource object for the custom data source. Before the operation, you must implement AVSourceReadAt.
89 // OH_AVDataSource dataSource = {fileSize, AVSourceReadAt};
93 Implement the **AVSourceReadAt** API before creating the resource object.
