null character at the end of text captions

[rjmorris.list@…]

When displaying text captions in videos created by Handbrake, MythTV prints an empty rectangle, representing a non-printable character, at the end of each caption. Inspection of the log messages suggests that the non-printable character is a null character (0x00). It is unclear whether the captions in the video file are stored incorrectly or whether MythTV makes an error when reading them.

Can you try the attached patch? It's against 0.27 / Master but I expect it should apply to 0.26.

The patch fixed the problem. Thanks!

Subtitles: Remove extraneous character in embedded text subtitles.

The NUL character at the end of the C string was accidentally being
included as part of the subtitle string, and rendered to the screen.
This affected only "raw text" subtitles directly embedded into the
video. Fixes #11855.
