1) Download the Plex application and install it on your computer - https://plex.tv/downloads
You will need to launch the installed Plex Media Client (program) each time you want to access your media on any of your devices (tablets, smartphones, [smart] tv and obviously your PSVita)
2) Follow this link: https://plex.tv/users/sign_in
If you want to create an account with Plex, select the option, "Don't have an account yet?". Set up and verify your account by following the onscreen instructions. When you are done follow this link, 127.0.0.1:32400/web, and you will be led to the Plex webpage where you can add your videos, music and photos. You can also add channels featured on Plex like YouTube, CollegeHumor, Dailymotion and PBS, to mention a few.
On the other hand if you do not wish to create an account with Plex, select the option, "Don't want an account?". You will be taken straight to the Plex webpage where you can add your photo, music and photos as well as channels featured on Plex like YouTube, CollegeHumor, Dailymotion and PBS.
After setting up your libraries and channels on Plex, anytime you launch the application, you will be taken to the Plex site where you will find all your items.
3) Find your private or local IP address.
For Mac users follow these instructions to find your local IP address. Click the Apple logo at the utmost top left hand corner of your Mac device and select the "System Preferences" menu. A Window should appear showing all of your settings. Select the "Network" menu. The network menu should appear and at the left should be a list of various cellular networks and connections including your Wi-Fi, Samsung Android and Bluetooth connection. Under the Wi-Fi pane should be an "Advanced..." menu at the bottom, select it. Under the TCP/IP pane should be your IPv4 address which is your local address, the one assigned to your computer by your network.
For Windows users, simply press the home button, search for and open command prompt. Type in "ipconfig", without the quotation marks. Beside the label IPv4 address should be your IP address.
4) Launch your PS Vita's web browser.
In the address bar of your Vita's web browser, type in the ip address of your computer followed by ":32400/web", without the quotes. The Plex webpage registered to your computer's IP address should open up and you should now have access to all the files you uploaded onto the Plex server via your computer.
LIMITATIONS TO USING PLEX ON THE VITA:
- Your music must be in the .mp3/AAC 2 format
- Your videos must be in the .mp4 format and must have a quality of 720p or lower.
NOTE: You always have to launch the Plex application you installed on your PC/Mac before trying to access your media on any of your devices otherwise, you will get an error saying that the server cannot be reached.
