I'd like to know what the people is doing with regards to snapshop
taking in actual applications.
For instance, the following pipelines could be constructed for image aquisition:
a) v4lsrc ! ximagesink
b) v4lsrc ! identity ! ximagesink
And when the user finally decides to take a snapshot, he clicks on the
What would be the best thing to do from a GStreamer point of view?
Steal the data between the v4lsrc and ximagesink elements in scenario
a), use identity's handoff signal from scenario b), or interchange the
sink element with a gdkpixbuf-like sink?
Moreover, what is an application supposed to do with the buffer? Once
it is in memory and the user decides to save it to a file (encoded in
whatever format the use chose), how is that buffer fed into a
GStreamer pipeline for encoding and saving?
Thanks and greetings!
