Hello @planetoffitness,
You can find all translation ready strings of rtMedia here - wp-content/plugins/buddypress-media/languages
Now, you can translate strings ( if they are not translated already ) in 2 ways.
1 . You can contribute to the translation project on WordPress.org. Once it is approved we will add newly translated strings to our next version of rtMedia.
or
2 . You can use your own translation. For that, you will need to use the .po
file to refer required string and generate a language specific .mo
file once you are done with the translation.
I hope this cleared your doubts.
Thank you.
