[gst-devel] seeking video file with background

[Kapil Agrawal]

Not sure but just a thought,

Maybe you can apply seeking on the video part of pipeline and not on the
whole pipeline.
So make a video bin having the video part before mixing and seek there ?

Note :Just an idea, havent validated or thought much about practical issues
:)

Thanks
Kapil
