Sorry for the delayed reply!
The MediaPlayer needs a list of RadMediaItems to play videos correctly (changing state, displaying descriptions, chapters, etc). Unfortunately the RadMediaItem does not offer a way set the local file as a source.
This task has been logged for a future version of the MediaPlayer but unfortunately currently I cannot offer a solution or workaround.
You can use the "Format Code Block
" tool of the editor when posting in the forum (the button looks like an orange paint brush).
Thank you for bringing our attention to this!
All the best,
the Telerik team
