[gst-devel] Capsfilter problem

[Andrea della Porta]

Hi again,

It seems that when resolving the intersection between two element with a
capfilter in between, the caps on the first element get caught from the
peer pad of the other pad of the element itself. So, in the example
stated:

 

GST_REGISTRY_FORK=no ./gst-launch videotestsrc pattern=1 !
ffmpegcolorspace zorder=56 ! video/x-raw-rgb-zorder,
framerate=\(fraction\)30/1, width=100,height=100 ! sdlvideosink

 

The resulting capslist to be linked to sdlvidesink0:sink will be taken
from ffmpegcolorspace0.sink ---> = peer_pad=videotestsrc0.src 

that obviously does not have a 'zorder' capability. It seems strange to
me cause this way every element connected to the ffmpegcolorspace should
implement that capability, that is in contrast to the usefulness of
ffmpegcolorspace itself. Implementing 'zorder' cap on videotesrc too
seems to work. Maybe I'm missing something, could anyone shed some light
on it?

 

Many thanks,

Andrew
