[Bug] OHIF does not use /rendered enpoint for video in an Orthanc Dicom Server #4257

Describe the Bug

Video reading in OHIF doesn't work if stored in an Orthanc server,

There is a difference in the /metadata API of OHIF dicom server and Orthanc

OHIF server answer is : "7FE00010": { "vr": "OB", "BulkDataURI": "series/2.25.15054212212536476297201250326674987992/instances/2.25.179478223177027022014772769075050874231/pixeldata.mp4?length=47363258&offset=0" },

while orthanc is : "7FE00010" : { "BulkDataURI" : "https://v2-test.gaelo.fr/dicom-web/studies/1.2.276.0.7230010.3.1.2.1667589682.1.1719172138.291254/series/1.2.276.0.7230010.3.1.3.1667589682.1.1719172138.291255/instances/1.2.276.0.7230010.3.1.4.1667589682.1.1719172138.291256/bulk/7fe00010", "vr" : "OB" }

OHIF seems to not detect that the content is a video and continue to call /frame/{number} API which are obviously failing, while it should call the rendered api

I don't know if this problem is related to Orthanc which might no follow a standard or if OHIF should have more flexibility ?
