ADDITIONAL OS VERSION INFORMATION :
Windows 7 64

A DESCRIPTION OF THE PROBLEM :
Clarification regarding that I don't see  limitation on Windows 7 to play full HD in portrait mode 1080x1920:

The bug JDK-8133841 was marked as a duplicate of JDK-8091277.

JDK-8091277 is for ultra HD res support and a comment states:
"We using DirectShow H.264 decoder to decode H.264 video This decoder only supports resolution up-to 1920x1088, so anything larger will not play". 
This seems unrelated to portrait resolution problem.

May be I miss something, but  dshowwrapper.cpp uses "Microsoft DTV-DVD Video Decoder" clsid 212690FB-83E5-4526-8FD7-74478B7939CD. I don't observe any limitation in directshow or this microsoft decoder to play portrait 1080x1920 mp4 video on Win 7 64bit machines. So it is different bug, unrelated to ultra HD support.

Simplest direct show graph [lav splitter source] -> [CLSID_CMPEG2VidDecoderDS= 212690FB-83E5-4526-8FD7-74478B7939CD] -> [any video renderer ] seems to play 1080x1920 mp4 file just fine on WIndows 7, so there is no limitation in the decoder itself. 

The same file on the same machine gives ERROR_MEDIA_INVALID in JavaFX 8u60. 

(btw. it may be also good idea to implement an  option to use system preferred filters and codecs, instead of hard coded clsids)
