stuck between a tee and a frustrating place.

Hi All,

Can someone give advice on the code below. Compiles with no errors,
however when I run it it stalls after giving the g_print message in
on_pad_added.

if I run with debug it will output all the caps with the last two lines

 videomixer2
videomixer2.c:315:gst_videomixer2_pad_sink_setcaps:<videomixer:sink_0>
Setting caps video/x-raw-yuv, format=(fourcc)AYUV, width=(int)600,
height=(int)300, framerate=(fraction)25/1,
pixel-aspect-ratio=(fraction)1/1, bpp=(int)16, depth=(int)16,
endianness=(int)1234, interlaced=(boolean)false
0:00:07.029304050  6097      0x25d8c00 INFO             videomixer2
videomixer2.c:1403:gst_videomixer2_src_setcaps:<videomixer:src> set src
caps: video/x-raw-yuv, format=(fourcc)AYUV, width=(int)640,
height=(int)352, framerate=(fraction)25/1,
pixel-aspect-ratio=(fraction)1/1

If I comment out the pipe1a it works as expected. can you advise if I am
missing something obvious and how to fix it.

thx
Art
