Some GStreamer issues while capturing while preview is active

Hi,

we want to record a mp4 file while preview(overlay) is running.

We have a application which activates the overlay an records a mp4 file on user input.

The error can also be reproduced using gst-launch. (gst-fsl-plugin-2.0.3)

With the gstreamer pipe

gst-launch mfw_v4lsrc capture-width=640 capture-height=480 num-buffers=150 ! mfw_ipucsc ! 'video/x-raw-yuv,width=640,height=480,framerate=30/1,format=(fourcc)I420' ! queue ! mfw_vpuencoder codec_type=std_mpeg4 qp=5 ! 'video/mpeg,mpegversion=4,framerate=30/1,width=640,height=480' ! mp4mux ! filesink location=test.mp4

I get this output and it works.

Seems you just added a "preview=true" is not enough.

Please see this link for your reference.
