[FEATURE] Add support for .ttml subtitles file format #1213

Open guyluz11 opened 1 year ago

guyluz11 commented 1 year ago

Is your feature request related to a problem? Please describe. Subtitles can arrive in several different formats for example .srt. I want to make certain wards in the subtitles bold (maybe also colored in the future).

Describe the solution you'd like There is a subtitle format named .ttml which enhances the options that can be done with subtitles.

Describe alternatives you've considered Reading the subtitles with another subtitle package like subtitle and viewing the correct one by the time.

Additional context Here is an example of .ttml file
