> 1) Subtitle delay :
This is indeed a missing playbin2 feature. Same for audio I guess, although
there one can use the sink's properties already. Retitling bug accordingly.
> 2) subtitle delay , apply :

> and write to subtitle file the3 time changes
playbin2 is for playback. It will never support something like that. You will
need to write a dedicated separate pipeline to remux the subtitle file and
apply a delay. You can probably do that already by using a pipeline such as
filesrc ! subparse ! srtenc timestamp=-1000000000 ! filesink. If you need more
help with this, please ask on IRC or the mailing list.

You can do that already by passing an appsrc:// URI and using appsrc. That's
the API GStreamer provides for this kind of thing. If you want to use a java
inputstream, you need to talk to the gstreamer-java people and ask them to
provide some API/wrappers. They need to do that, there's not much we can do
about this.
> 4) get subtitle language from playbin it self
> it will be nice the have it from new property "text-language" gint.
You can do that already (totem does it after all). Use the get-text-tags action
signal and look at the GST_TAG_LANGUAGE tag in the taglist. If you need more
help to make this work, please ask on IRC or the mailing list.
> 5) "suburi" property :
> dos not work at run time ,
> very bad i need to restart a player just to change subtitle
It works quite well 'at run time', but ony before you start playback. You don't
need to restart the player application, just interrupt/restart the current
playback. But in any case, there's already a bug for this, namely bug #589515.
In short, let's keep this bug about the subtitle delay and A/V sync properties.
PS: Version 0.10.6? Of what module? (core/base 0.10.6 is ancient..)
