You need to create nfo files for each movie. This nfo file should be stored in your local drive in individual folders for each movie, with the nfo, strm, the poster and the fanart files  

Thank you @z3us 
Really appreciate your response.
Yes, I am aware of the NFO file solution. However, since Kodi is successfully able to show the media information DURING playback of the STRM file, I thought it should be possible to show the same media info in the movie library as well. Hope this issue gets resolved in a future version of Kodi/Google Drive Plugin.

For now, will continue to use NFO files to scrape STRMs, as long as no other solution is available.  

I guess that's because the strm file is essentially just a file with an https address to your media and not as such your media. If you try to use google drive in "source mode", you may be able to get the media flags.

Another option is to rename your files on google drive to include the codes in the filename itself and if you use it with particular skins (e.g, Estuary Mod v2) that extracts the media flags from the title you may be able to see those media flags. I tried this with Estuary Mod v2 in Kodi 17.6. But, my problem was different. Kodi remembers the resume points for your media with the file name and not the movie or episode. So, every time I upgrade the media, and hence file gets a new name, the resume points would not work for the same movie or episode. So, I started naming them as Movie Name (Year) irrespective of the resolution, codecs, etc to maintain the resume points. 

Hi @vab.patel 
Thank you for your response.
Yes, I am thinking of using that filename technique for extracting the video information.
However, correct me if I'm wrong, isn't it no longer possible to use Google Drive as a source using cguZZMan's plugin due to changes made by Google a few months ago? I mean, you might be able to set up Google Drive as a source in Kodi, but the files will no longer play in Source Mode, isn't that correct?
