RTSP Seek and DVB subtitles

[Alexander Olekhnovich]

Hi gstreamer team and community,

I'm working with gstreamer and trying to develop some extra features for gstreamer as all we are.

To proceed my investigation I need some info:

1) Is somebody working on the following RTSP seeking bug? https://bugzilla.gnome.org/show_bug.cgi?id=550634

2) Is somebody working on DVB subtitling (ts dvb subs) on gstreamer? I found no information regarding DVBSUBS in gstreamer (private/x-dvbsub is not being handled), but found some source code of it in gst-ffmpeg. Is there anybody interested in supporting of this feature in gstreamer?

I appreciate any information regarding this issues.

Thank you,
Alexander Olekhnovich

Regarding dvb subtitles, there is a little bit of work going on. One
with gst-teletext to grab subtitles from teletext and another with
image subtitles.

I've got a working implementation that I am willing to share if ppl are
interested.

You can use pango to get an approximate of a full TT page or just get
the subs (page) in text format.

Tested on a number of DVB-S streams with good result.

Hi Marc,

I think ppl are interested :) At least I would really like to have a look at that.

I have tested it with Western European languages (Italian, French,
German, English, Dutch); but not with Eastern (or others).

Submitted it to gstreamer:
https://bugzilla.gnome.org/show_bug.cgi?id=618850

Using the pango=True parameter allows you to get an approx of the TT
page on TV (there are some issues with the gfx chars in TT that have no
counterpart in UTF8).

This is clearly another case of too many mad scientists, and not enough
hunchbacks.
