#10728 closed Bug Report - General (fixed)

Black outline around subtitles

Reported by: kane.tse@… Owned by: Jim Stichnoth
Priority: trivial Milestone: 0.25.1
Component: MythTV - Captions Version: 0.25-fixes
Severity: low Keywords:
Cc: Ticket locked: no


Under MythTV-0.24, when the "solid black background" option is OFF, CC-608 and external subtitles were rendered with a thin black border around them. This enhances caption readability when the recording is on a bright/white scene, without obstructing too much of the recording underneath.

A fix was backported to 0.24-fixes by Mark Kendall as referenced in this thread from the MythTV-users discussion list:

... however, there was no mention of a specific patch# to confirm if it is still present in 0.25.

This ticket is being created at the recommendation of a developer who has offered to look through the history and incorporate this fix into 0.25-fixes. This ticket will be used for tracking this work.

b674e521028d49193c7d52fa749c556f423cd9f8 is probably the commit being referred to, which extended the black outlines for text (e.g. srt) subtitles to include CEA-608 captions as well.

Fixes #10728. Draw a black outline around text subtitles for contrast.

This fixes a regression in external and CEA-608 captions when no black
background is displayed.
