Hi,
I faced same issue and maybe found a solution.
In your log, it is saying : Unexpected MPEG color primaries value!
I’ve re-encode with handbrake and a different codec and worked for me, here are the settings i’ve used
CODEC : H.264 (NVEnc) file in .mp4 format
Color Space : BT.709 → you’ll find this in the filter tab and this is probably the thing that solve the mpeg color primaies value issue.
Tell me if it worked for you and apply solved if it’s ok
Thanks

Just had the same error with Unreal Engine 5.4 and exported project.
The file is in MP4 codec, other MP4 play fine.
Need ElectraPlayer to play *.mpd files.
The code
#include "HAL/Platform.h"
#include "ColorManagementDefines.h"
namespace ElectraColorimetryUtils
{
static constexpr uint8 DefaultMPEGColorPrimaries = 1;
static constexpr uint8 DefaultMPEGMatrixCoefficients = 1;
static constexpr uint8 DefaultMPEGTransferCharacteristics = 1;
UE::Color::EColorSpace TranslateMPEGColorPrimaries(uint8 InPrimaries)
{
switch (InPrimaries)
{
case 1: // Rec709
case 2: // unknown
return UE::Color::EColorSpace::sRGB;
case 9: // Rec2020
return UE::Color::EColorSpace::Rec2020;
default:
check(!"Unexpected MPEG color primaries value!");
}
return UE::Color::EColorSpace::sRGB;

Thank you very much. Your solution works!
