MediaInfo源代码分析 1整体结构 MediaInfo源代码分析 2API函数 MediaInfo源代码分析 3Open()函数 MediaInfo源代码分析 4Inform()函数 MediaInfo源代码分析 5JPEG解析代码分析 我们来看一下MediaInfo中的Open()函数的内部调用过程
首先open函数封装了MediaInfo_Internal类中的open()函数
//打开文件
size_t MediaInfo::Open(const String File_Name_)
{//封装了一层return Internal-Open(File_Name_);
}
查看一下MediaInfo_Internal类中的open()函数的源代码
//打开文件
size_t MediaInfo_Internal::Open(const String File_Name_)
{Close();CS.Enter();MEDIAINFO_DEBUG_CONFIG_TEXT(Debug__T(Open, File);DebugZtring(File_Name_).c_str();)//清空文件列表Config.File_Names.clear();if (Config.File_FileNameFormat_Get()__T(CSV)){Config.File_Names.Separator_Set(0, __T(,));Config.File_Names.Write(File_Name_);}//添加文件名到文件名列表else if (!File_Name_.empty())Config.File_Names.push_back(File_Name_);if (Config.File_Names.empty()){CS.Leave();return 0;}Config.File_Names_Pos1;CS.Leave();//Parsing//解析if (BlockMethod1){if (!IsInThread) //If already created, the routine will read the new files{Run();IsInThreadtrue;}return 0;}else{Entry(); //Normal parsingreturn Count_Get(Stream_General);}
}
在打开之前首先调用Close()进行清理将文件路径添加到一个列表实际上是一个Vector中调用Entry()进行解析。
查看一下Entry()函数的源代码
//解析函数
void MediaInfo_Internal::Entry()
{CS.Enter();MEDIAINFO_DEBUG_CONFIG_TEXT(Debug__T(Entry);)Config.State_Set(0);CS.Leave();//解析文件名是否包含MMS//需要libmmsif ((Config.File_Names[0].size()6 Config.File_Names[0][0]__T(m) Config.File_Names[0][1]__T(m) Config.File_Names[0][2]__T(s) Config.File_Names[0][3]__T(:) Config.File_Names[0][4]__T(/) Config.File_Names[0][5]__T(/))|| (Config.File_Names[0].size()7 Config.File_Names[0][0]__T(m) Config.File_Names[0][1]__T(m) Config.File_Names[0][2]__T(s) Config.File_Names[0][3]__T(h) Config.File_Names[0][4]__T(:) Config.File_Names[0][5]__T(/) Config.File_Names[0][6]__T(/)))#if defined(MEDIAINFO_LIBMMS_YES)Reader_libmms().Format_Test(this, Config.File_Names[0]);#else //MEDIAINFO_LIBMMS_YES{#if MEDIAINFO_EVENTSstruct MediaInfo_Event_Log_0 Event;Event.EventCodeMediaInfo_EventCode_Create(MediaInfo_Parser_None, MediaInfo_Event_Log, 0);Event.Type0xC0;Event.Severity0xFF;Event.MessageCode0;Event.MessageStringULLibmms cupport is disabled due to compilation options;Event.MessageStringALibmms cupport is disabled due to compilation options;MediaInfoLib::Config.Event_Send((const int8u*)Event, sizeof(MediaInfo_Event_Log_0));#endif //MEDIAINFO_EVENTS}#endif //MEDIAINFO_LIBMMS_YES//是否包含网络协议标记为:////需要使用libcurl - the multiprotocol file transfer libraryelse if (Config.File_Names[0].find(__T(://))!string::npos)#if defined(MEDIAINFO_LIBCURL_YES){CS.Enter();if (Reader){CS.Leave();return;

}
我们可以看出MediaInfo支持流媒体协议作为输入源例如mms但前提是要使用相应的库libmms或者libcurl。它会首先查找文件路径中有没有“://”判断是否是流媒体输入。
大多数情况下我们使用本地文件路径作为输入源。这是我们就进入了代码中“#if defined(MEDIAINFO_FILE_YES) 部分下面的代码。具体每块代码的左右都写在代码注释中了不再细说。最后使用 Reader_File的Format_Test()测试输入文件的格式。
看一下Reader_File的Format_Test()的源代码
//用于测试文件格式
size_t Reader_File::Format_Test(MediaInfo_Internal* MI, String File_Name)
{//std::coutZtring(File_Name).To_Local().c_str()std::endl;//With Parser MultipleParsing/*MI-Open_Buffer_Init((int64u)-1, File_Name);if (Format_Test_PerParser(MI, File_Name))return 1;return 0; //There is a problem*///Get the Extension//文件后缀Ztring ExtensionFileName::Extension_Get(File_Name);Extension.MakeLowerCase();//Search the theorical format from extensionInfoMap FormatListMediaInfoLib::Config.Format_Get();InfoMap::iterator FormatFormatList.end();if (!MI-Config.File_ForceParser_Get().empty())FormatFormatList.find(MI-Config.File_ForceParser_Get());if (FormatFormatList.end()){FormatFormatList.begin();while (Format!FormatList.end()){const Ztring ExtensionsFormatList.Get(Format-first, InfoFormat_Extensions);if (Extensions.find(Extension)!Error){if(Extension.size()Extensions.size())break; //Only one extenion in the listif(Extensions.find(Extension__T( ))!Error|| Extensions.find(__T( )Extension)!Error)break;}Format;}}if (Format!FormatList.end()){const Ztring ParserFormat-second(InfoFormat_Parser);if (MI-SelectFromExtension(Parser)){//Test the theorical formatif (Format_Test_PerParser(MI, File_Name)0)return 1;}}//遍历所有支持格式测试格式size_t ToReturnMI-ListFormats(File_Name);return ToReturn;
}
可以看出最后遍历了所有支持的格式试图找出合适的格式。 最后我们看一下ListFormats()函数用于找出匹配的格式。
由代码可见遍历测试每一种支持的格式。
int MediaInfo_Internal::ListFormats(const String File_Name)
{// Multiple// 看看这些格式都是否支持//从上往下遍历//如果遇到某一格式返回值为1便不再进行//否则就进行下一个直到遍历完#if defined(MEDIAINFO_BDAV_YES)delete Info; Infonew File_MpegTs(); ((File_MpegTs*)Info)-BDAV_Size4; if (((Reader_File*)Reader)-Format_Test_PerParser(this, File_Name)0) return 1;#endif#if defined(MEDIAINFO_BDMV_YES)delete Info;
