I am trying to resize the video frames using mfw_v4lsink in my application , but it's not working.


mfw_v4lsink is giving error : image crop to 0 or image out of screen.



To debug this issue ,  when i tried with gst-launch-0.10, it was working.

gst-launch-0.10 filesrc location=/wfdsink/tools/dump.ts ! tsdemux ! vpudec ! mfw_v4lsink disp-width=800 disp-height=450.


When i changed the video sink to mfw_isink , then my application was able to resize the video frames.


so, why mfw_v4lsink is not able to resize the video frames , while the same thing is working with mfw_isink.
