[gst-devel] seeking video file with background

[Juan Felipe Mogollón Rodríguez]

Hi

I am trying a build an applicaction that mixes two diferent videos and
shows them with a background image following the next pipeline:

gst-launch filesrc location=video1.ogg ! decodebin !  videobox
border-alpha=0 alpha=1 top=-375 bottom=0 left=-250 right=0 ! alpha
method=3 angle=90 ! videomixer name=mixer ! ffmpegcolorspace !
xvimagesink filesrc location=video2.ogg ! decodebin ! videobox
border-alpha=0 alpha=1 top=-375 bottom=0 left=-400 right=0 ! alpha
method=3 angle=90 ! mixer. filesrc location=background.jpg ! decodebin
! imagefreeze !  alpha method=0 target-r=0 target-g=0  target-b=0 !
videoscale ! video/x-raw-yuv, width=1200, height=800 ! mixer.


When I try to seek the videos, I am always getting a seek error, I
think that the error appears because of the still image that is
created to be used as background, I have tried with multifilesrc and
with imagefreeze, but I always get that seek error.

Does anybody knows another way to get a static background image that
can be seekable?

Thanks in advance.

Regards.


Felipe.
