Changing Segment without seek

[Patrick Fü]

I'm trying to change the segment while in playing state with gst_event_new_seek.

When the current time lies within the new segment it currently does a seek to the beginning of the new segment.

What's the best to set a segment without doing a seek ? Is it even possible with gst_event_new_seek ? 

Thanks. 

Patrick

Let's take back a step. Cold you explain in some more detail what you
are trying to implement or achieve exactly? Then we can give advice how
to best do that.

For things like gapless/seamless playback or looping you can use the
GST_SEEK_FLAG_SEGMENT, then your app will get a SEGMENT_DONE message on
the bus as soon as the source/parser/demuxer is done processing data,
and then you can do another (non-flushing) seek to output more data. If
that's what you want I don't know though :)

Cheers

Hey Tim, 

thanks for the fast response. 

Seamless looping is working fine and I do it as you described, even for parts of a video.  

But what I want to achieve is changing the looping segment dynamically while playing. And when the current position is within a new segment it shouldn't seek to the beginning of the segment to get seamless playback. 

Another things would be to reset a smaller segment to the full video length without doing a seek, to get seamless playback. 

Hope this explains my question. 

Cheers, 

Patrick

I believe you should be able to create a seek event with
start/start_type as NONE, and then just the stop position should be
updated. If that actually works properly everywhere I don't know.
