The following pipeline is intended to simulate capturing two streams, mixing them picture-in-picture, muxing in audio and writing the result to a file:
hres=960
vres=544
hres2=`expr $hres / 2`
vres2=`expr $vres / 2`
xpos=$hres2
ypos=$vres2
framerate=60
audiosamples=`expr 44100 / $framerate`
duration=10
queuesize=12
buffers=`expr $framerate \\* $duration`
gst-launch --gst-debug=3 --verbose \
omx_videomixer framerate=$framerate port-index=0 name=mix \
sink_00::outX=0 sink_00::outY=0 \
sink_00::outWidth=$hres sink_00::outHeight=$vres \
sink_01::outX=$hres2 sink_01::outY=$vres2 \
sink_01::outWidth=$hres2 sink_01::outHeight=$vres2 \
! "video/x-raw-yuv,width=$hres,height=$vres,format=(fourcc)YUY2" \
! omx_noisefilter \
! "video/x-raw-yuv,width=$hres,height=$vres,format=(fourcc)NV12" \
! omx_h264enc \

! avimux name=mux \
! filesink location=capture_test_544.avi \
v4l2src always-copy=false queue-size=$queuesize num-buffers=$buffers \
! 'video/x-raw-yuv-strided,format=(fourcc)NV12,width=1920,height=1080,framerate=(fraction)60/1' \
! omxbufferalloc numBuffers=$queuesize \
! tee name=vidsource \
vidsource. ! queue ! mix. \
vidsource. ! queue ! mix. \
audiotestsrc samplesperbuffer=$audiosamples num-buffers=$buffers \
! queue ! mux.
The video source is 1080p60 and connected to the component video inputs on the evaluation board. The environment is the EZSDK 5_05_02_00 and GST_DM81XX_00_07_00_00.
When run as shown above, it runs correctly and generates a 960x544 avi file. If I change the resolution to be 1920x1088, the pipeline hangs, and none of the debug info indicates a problem of any sort. If I change the resolution to be 1200x736, the pipeline also hangs, but the debug info includes the following lines:

I need the pipeline to work at full resolution...
