Hi all,
I'm working on gstreamer java.
In my scenario I added a custom module that perform cyphering.
This module is positioned just after the video demuxer.
I need to cypher my stream with different keys every "x" seconds. (X is read
from DB and should correspond to the PTS).
In order to synchronize to these "x" seconds I am trying to pause the
pipeline, set the cypher module with new key and play the pipeline again for
every key.
E.g.
We have First key from 0 to 4999 millisec, Seconf key from 5000 to 10000
millisec.
How can I know when the pipeline reaches 4999 millisec?
I tryed to use the seek operation from 0 to 4999, when it ends the EOS
Listener (Bus.EOS()) catches it and I pause the pipeline.
Inside Bus.EOS() I do the seek for the second key.
The problem is that time is not synchronized. (e.g. after first key, inside
Bus.EOS() time is already 5020).
I have also tryed with a while operation: while(pipeline.isPlaying()). In
this loop I look at the queryPosition() and when it gets over 4999, I pause
the pipeline, set the module with new key and so on...
The problem is the same.
Can you give me any ideas?
Thanks in advance.
Dodo
