Comment:
I'm not too sure if this is a MythTV/ffmpeg bug or a broadcasting issue.
In 0.22, DVB subtitle positioning was based upon fixed, standard
definition resolutions. To fix HD subtitles, the positioning is now
relative to the video size (i.e. for HD streams, we assume the subtitle
bitmaps are sized and positioned relative to 1920x1080). This works for
all standard definition streams and all other HD streams I have seen. In
this instance (and #8287), subtitles are clearly still sized and
positioned on the assumption of SD resoltions but within an HD video
stream. FFMPEG does not appear to provide any additional hints, however,
as to the appropriate scale to use.
VLC appears to get this right.
