NS_E_VIDEO_CODEC_NOT_INSTALLED
What NS_E_VIDEO_CODEC_NOT_INSTALLED actually isolates
NS_E_VIDEO_CODEC_NOT_INSTALLED (0xC00D0BC4) reports that the required video codec is not installed or cannot be activated for the selected stream. The useful diagnostic unit is the exact object and operation, not the product name alone.
Keep these facts stable
capture video subtype/FOURCC, profile, expected codec CLSID, process bitness, and COM/codec enumeration results.
Corrective test
install the supported codec for that format or select an output/input format the deployed runtime can decode/encode. Avoid broad reinstalls or policy changes until that controlled test changes the result.
