Android Marshmallow “Can't play this video” error

Question

I am in the process of upgrading an app to android 6.0. Everything seems to be alright except when trying to play certain videos from a remote source. They play just fine on

Answer 1

Videos with ODSM / SDSM codecs can bypass being deinterlaced, but it appears Android Marshmallow will not recognize ODSM / SDSM codecs and will require the videos to be deinterlaced. Previous OS versions will not play videos that haven't been deinterlaced normally, with the exception being the video file including ODSM or SDSM codecs.

I believe this is due to Quicktime support issues, and may need to be opened as a defect with Android Marshmallow, but may also be intended by Google.
