Hi to all.
I'm trying to write a stop-motion creation app, in the vein of
but using python, gtk, and well, gstreamer. It's my first using all
three technologies, tough :p
What i'm stump on is on how step frame by frame forward and backwards in
a video loaded trough multifilesrc. I was trying to seek using
gst.FORMAT_BUFFERS as to move one frame at a time, but it doesn't work.
When i attempt a query_position on the pipeline, i get a "query failed".
My pipeline is
multifilesrc ! jpegdec ! cspvideo !videosink.
(multifilesrc has a "image/jpeg,framerate=15/1" cap for correct playing)
I've tried a queue right after multifilesrc, but no difference. Is there
something i have to do for a stream be seekable? Also, the idea is being
able to keep adding image frames without having to reprocess everything
