I'm setting up a pipeline with gst-launch to chromakey one video over
another. I've got it working with output to the screen. However, I want to
send the composite to a new movie. But, I can't correctly fit a filesink
into the pipeline. Here's what I've got that works. Can anyone tell me how
to add the output?
gst-launch-0.10 \
-e filesrc location="over.mov" \
! decodebin \
! queue \
! ffmpegcolorspace \
! alpha method=custom target-r=0 target-g=0 target-b=255 \
! videobox border-alpha=0 right=1 \
! videomixer name=mix \
! ffmpegcolorspace \
! autovideosink filesrc location="under.mov" \
! decodebin \
! queue \
! ffmpegcolorspace \
! videobox border-alpha=0 left=1 \
! mix.
