It depends on the format. The splitters, decoders are mostly internal Adobe licensed codecs such as from Mainconcept. A few AVI formats can use Windows VFW installed codecs

Prores, DNxHR use their respective Adobe implementations, not 3rd party or installed codecs

The demxuer and decoders are the .dll's in the AME folder under Program Files/Adobe/Adobe Media Encoder (version) . e.g. DNxHR uses DNxHR.dll

Adobe has used it's own MOV demuxer for many years , and the MXF demuxer is licensed from MOG and Mainconcept

Found it!: Adobe uses the ARRIRAW codec to temporarily import video files!

What are you talking about ?
It doesn't use anything temporary- it's not an old AVID or anything like this.
All current software NLEs, transcoders etc,. decode files in fly to uncompressed data (in memory) and from that proces it further.
That uncompressed data can be anything from 8bit up to 32bit float RGB/YUV depending on source/destination format. There is no loss and any extra processing or storage or codec involved.

ArriRAW is a RAW data out of Arri cameras - It's not even a codec, but simple uncompressed RAW Bayer data stored in MXF container. It has absolutely nothing to do with Adobe itself (except that Adobe like many other tools can read it).

ProRes and DNxHR are handled through Apple/AVID official decoders in AME.
