Description
This patch adds support for decoding Closed Captions in ATSC mpeg streams. These are the "old-style" EIA-608 captions which seem to be present in most ATSC broadcasts. This patch also includes decoding of Closed Captions (not subtitles) in DVD mpeg streams. Both caption-styles are contained in User Data mpeg packets. For the captions to be correctly displayed, the patch in Ticket #667 is required.
The patch is in two parts. The first part moves the existing CC decoding support from NuppelVideoRecorder? to a new CCDecoder class so that it can be shared with the frontend. The second part adds the actual support for ATSC and DVD decoding.
