I can't get the source to compile in VS2012.
At first if complains that hmac.h is missing, so I found that file and added the directory to the include list, then it complains that "unresolved external symbol _hmac_sha | C:\Projects\MediaInfo\MediaInfoLib\Project\MSVC2012\Dll\MediaInfo.lib(Reader_libcurl.obj) | MediaInfoDll" Anyway, I'm pretty sure all you'd have to do to fix part of the Matroska Tags issue is to, in file_mk.cpp, replace this line Code:
if (Retrieve((stream_t)StreamKind, StreamPos, General_ID)==ID) https://github.com/MediaArea/MediaIn...e_Mk.cpp#L2181 with Code:
if (Retrieve((stream_t)StreamKind, StreamPos, General_UniqueID)==ID) Code:
if (Segment_Tag_SimpleTag_TagNames[0]==__T("BPS")) return; //Useless
https://github.com/MediaArea/MediaIn...e_Mk.cpp#L2146 with this: Code:
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_WRITING_APP")) return; //Useless
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_WRITING_DATE_UTC")) return; //Useless
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_TAGS")) return; //Useless
(It doesn't check to see if they're in the correct file, but it's better than what's happening now. I can't tell if all the tags have been read by that point or how to iterate through them and compare them to the headers.) I can't compile it to check. -edit- This would be even better (I think) Code:
if (Segment_Tag_SimpleTag_TagNames[0]==__T("BPS")) {Segment_Tag_SimpleTag_TagNames[0]=__T("*Bit rate"); TagString.append(__T(" bps"));}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("DURATION")) {Segment_Tag_SimpleTag_TagNames[0]=__T("*Track duration/(HH:MM:SS.NNNNNNNNN");}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("NUMBER_OF_FRAMES")) {Segment_Tag_SimpleTag_TagNames[0]=__T("*Track size/(Frames)");}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("NUMBER_OF_BYTES")) {Segment_Tag_SimpleTag_TagNames[0]=__T("*Track size/(Bytes)");}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_WRITING_APP")) return; //Useless
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_WRITING_DATE_UTC")) return; //Useless
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_TAGS")) return; //Useless

How's this:
https://github.com/MediaArea/MediaIn...le_Mk.cpp#L385 Code:
//Tags
bool Tags_Verified=false;
Ztring TagsList=Retrieve(Temp->second.StreamKind, Temp->second.StreamPos, "Security Tags List", Info_Text);
if (!TagsList.empty())
{
Clear(Temp->second.StreamKind, Temp->second.StreamPos, "Security Tags List");
Ztring WritingApp=Retrieve(Temp->second.StreamKind, Temp->second.StreamPos, "Security Writing Application", Info_Text);
Ztring WritingDate=Retrieve(Temp->second.StreamKind, Temp->second.StreamPos, "Security Writing Date", Info_Text);
if ((!WritingApp.compare(Retrieve(Stream_General, 0, "Encoded_Application", Info_Text))) && (!WritingDate.compare(Retrieve(Stream_General, 0, "Encoded_Date", Info_Text))))
{ Fill(Temp->second.StreamKind, Temp->second.StreamPos, "*Statistics Tags Varified", "True"); Tags_Verified=true; }
else
Fill(Temp->second.StreamKind, Temp->second.StreamPos, "*Statistics Tags Varified", "False");
Clear(Temp->second.StreamKind, Temp->second.StreamPos, "Security Writing Application");
Clear(Temp->second.StreamKind, Temp->second.StreamPos, "Security Writing Date");
Ztring::iterator Back = TagsList.begin();
Ztring TempTag;
while (true)
{
if ((Back == TagsList.end()) || (*Back == ' ') || (*Back == '\0'))
{
if (TempTag == __T("BPS")) { TempTag = __T("Bit rate"); }
else if (TempTag == __T("DURATION")) { TempTag = __T("Track Duration/(HH:MM:SS.NNNNNNNNN)"); }
else if (TempTag == __T("NUMBER_OF_FRAMES")) { TempTag = __T("Track Size/(Frames)"); }
else if (TempTag == __T("NUMBER_OF_BYTES")) { TempTag = __T("Track Size/(Bytes)"); }
Ztring TagValue = Retrieve(Temp->second.StreamKind, Temp->second.StreamPos, TempTag.To_Local().c_str(), Info_Text);
if (!TagValue.empty())
{
Clear(Temp->second.StreamKind, Temp->second.StreamPos, TempTag.To_Local().c_str());
Fill(Temp->second.StreamKind, Temp->second.StreamPos, __T('*') + TempTag.To_Local().c_str(), TagValue.To_Local().c_str());
}
if (Back == TagsList.end()) break;
TempTag.clear();
}
else
TempTag+=*Back;
Back++;
}
}
Code:
if (Segment_Tag_SimpleTag_TagNames[0]==__T("BPS")) {Segment_Tag_SimpleTag_TagNames[0]=__T("Bit rate"); TagString.append(__T(" bps"));}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("DURATION")) {Segment_Tag_SimpleTag_TagNames[0]=__T("Track Duration/(HH:MM:SS.NNNNNNNNN)");}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("NUMBER_OF_FRAMES")) {Segment_Tag_SimpleTag_TagNames[0]=__T("Track Size/(Frames)");}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("NUMBER_OF_BYTES")) {Segment_Tag_SimpleTag_TagNames[0]=__T("Track Size/(Bytes)");}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_WRITING_APP")) {Segment_Tag_SimpleTag_TagNames[0]=__T("Security Writing Application");}
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_WRITING_DATE_UTC")) {Segment_Tag_SimpleTag_TagNames[0]=__T("Security Writing Date"); TagString.insert(0, __T("UTC ")); }
if (Segment_Tag_SimpleTag_TagNames[0]==__T("_STATISTICS_TAGS")) {Segment_Tag_SimpleTag_TagNames[0]=__T("Security Tags List");}

I moved the tag processing up to the top of File_MK.cpp | File_Mk::Streams_Finish() so I could try to set the tag duration as a proper duration. I have no idea if the code will work though.
Code:
Ztring Duration_Temp, Codec_Temp;
if (Tags_Verified)
{
Duration_Temp = Retrieve(Temp->second.StreamKind, Temp->second.StreamPos, "*Track Duration/(HH:MM:SS.NNNNNNNNN)", Info_Text);
if (!Duration_Temp.empty())
{
Ztring::iterator Front = Duration_Temp.begin();
Ztring Parts [4];
int CountParts = 0;
while (true)
{
if (Front == Duration_Temp.end() || *Front == __T(':') || *Front == __T('.'))
{
CountParts++;
if (Front==Duration_Temp.end() || CountParts == 4) break;
}
else if (isdigit(*Front))
Parts[CountParts]+=*Front;
Front++;
}
if (CountParts == 4)
{
int64u Hours = Parts[0].To_int64u(10);
int64u Minutes = Parts[1].To_int64u(10);
int64u Seconds = Parts[2].To_int64u(10);
Parts[3] = Parts[3].substr(0, 3);
int64u Milliseconds = Parts[3].To_int64u(10);
Duration_Temp.From_Number((((Hours * 3600) + (Minutes * 60) + Seconds) * 1000) + Milliseconds, 10);
//Fill(StreamKind_Last, StreamPos_Last, Fill_Parameter(StreamKind_Last, Generic_Duration), Duration_Temp, true);
//Clear(Temp->second.StreamKind, Temp->second.StreamPos, "*Track Duration/(HH:MM:SS.NNNNNNNNN)");
}
else Duration_Temp.clear();
}
}
if (Duration_Temp.empty())
Duration_Temp=Retrieve(StreamKind_Last, Temp->second.StreamPos, Fill_Parameter(StreamKind_Last, Generic_Duration)); //Duration from stream is sometimes false
... ... Am I missing a library somewhere or is hmac.h not actually supposed to be included? I really want this tag business done with. Last edited by ndjamena; 9th November 2015 at 06:56. |

How are you building it? Only the MSVC 2013 project is kept up to date, which has it in the MediaInfoLib project under ThirdParty/hmac, so it should always be built with the rest of the lib. Don't use the older projects unless you regenerate them from cmake first. The GNU project is also kept up to date if you use mingw/gcc.

But I definitely can not support indefinitely all MSVC versions, so I just trashed MSVC 2005 / 2008 / 2010 projects. I plan to keep MSVC 2012 and 2013 projects, and also propose soon MSVC 2015 project.

Actually all MSVC versions since VS2010 use the same Project file format. So you can just keep the VS2013 project up-to-date and still open it in VS2010/VS2012.
In my experience, VS2010 or VS2012 will complain that it doesn't support toolset "v120" when you open the VS2013 project, but you can easily fix that by changing the toolset to "v100" or "vs110" as needed. The rest usually works fine.

Hi,
am trying to use mediainfo to import file information, but i can't seem to get the right code for height and width of a moviefile. these work fine: Dim temp_FileName As String = MI.Get_(StreamKind.General, 0, "FileName") Dim temp_FileSize As String = MI.Get_(StreamKind.General, 0, "FileSize") Dim temp_FileOverallBitRate As Decimal = MI.Get_(StreamKind.General, 0, "OverallBitRate") Dim temp_FileDuration As Integer = MI.Get_(StreamKind.General, 0, "Duration") but here i kinda am lost when i want height / width Dim temp_Filewidth1 As String = MI.Get_(StreamKind.General, 0, "Width_Original") Dim temp_FileWidth2 As String = MI.Get_(StreamKind.Video, 0, "Width") Dim temp_FileWidth3 As String = MI.Get_(StreamKind.Video, 1, "Width_Original") Dim temp_FileWidth4 As String = MI.Get_(StreamKind.Video, 0, "Width/string") Dim temp_FileWidth5 As String = MI.Get_(StreamKind.Video, 1, "Width/string") i'm a bit confused, where am i going wrong? (hope someone can/will help) file info: PHP Code:

for 99% of people, MI.Get_(StreamKind.Video, 0, "Width") is the only one needed.

Edit: Actually, I take that back, it looks like MediaInfo should be able to run against raw HEVC too now. What file format is your test file being detected as? Last edited by foxyshadis; 10th November 2015 at 06:51. |

Here, the frame rate is also filled in the HEVC bitstream, I would rely more on it.

But does that explain why MI.Get_(StreamKind.Video, 0, "Width") gives me 0 results?
If i use: MI.Option_("Complete") To_Display += MI.Inform() which gives above info, it shows the width, but if i use MI.Get it shows no value. |
