Yes, maybe I should open this issue in MediaArea/MediaInfoLib?

Visual Studio's Analysis also found some potential memory-related issues and other issues with MediaInfoLib. I'm not sure if there are any false positives and whether they can actually be encountered in normal use or be exploited. Therefore I didn't open a new issues about this but thought I should let you know in case you haven't known. Below are some examples. More can be seen by executing Analyze > Run Code Analysis > Run Code Analysis on MediaInfoLib in Visual Studio.

Redundant/repeated checks in if statements which I don't know is intentional or mistake/bug:

Cppcheck also found:

Id: arrayIndexOutOfBoundsCond
CWE: 788
Either the condition 'Code>=0x80' is redundant or the array 'Iab_Channel_Values[34]' is accessed at index 104, which is out of bounds.

MediaInfoLib/Source/MediaInfo/Audio/File_Iab.cpp

Lines 117 to 118 in dbed027

if (Code>=0x80 && Code<sizeof(Iab_Channel_Values)/sizeof(const char*)-0x18)
return Iab_Channel_Values[Code-0x18];

If I understand the intention correctly, I think this should be:

if (Code>=0x80 && Code-0x68<sizeof(Iab_Channel_Values)/sizeof(const char*))
        return Iab_Channel_Values[Code-0x68];

Warning	C6385	Reading invalid data from 'vDk0'.	MediaInfoLib	>\MediaInfoLib\Source\MediaInfo\Audio\File_Aac_GeneralAudio_Sbr.cpp	947

This one likely a false positive since there is already a check:

MediaInfoLib/Source/MediaInfo/Audio/File_Aac_GeneralAudio_Sbr.cpp

Lines 896 to 897 in abdbb21

if (numBands0 == 0 || numBands0 >= 64)
return false;

So this should not be possible to be out-of-bounds:

MediaInfoLib/Source/MediaInfo/Audio/File_Aac_GeneralAudio_Sbr.cpp

Line 947 in abdbb21

if (vDk1[0]<vDk0[numBands0-1])
