Regarding the (In reply to comment #1)
> Do you have an specific input/file that triggers this?

I'm using the next pipelines:
 gst-auto-launch \
  qtmux name=mux mux.src ! \
  filesink location=/home/ubuntu/MPEG4ENC_FUNCTIONAL_00001.mov \
  omx_camera mode=1 vstab=false vnf=off exposure=1 awb=3 ldc=true zoom=200
focus=3 output-buffers=4 device=secondary name=cam \
  cam.src ! \
      "video/x-raw-yuv-strided, format=(fourcc)NV12, width=176, height=144,
framerate=30/1, buffer-count-requested=4" ! \
  queue name=q3 ! \
  v4l2sink device=/dev/video2 min-queued-bufs=2 sync=false crop-top=0
crop-left=0 crop-width=176 crop-height=144 \
  cam.vidsrc ! \
      "video/x-raw-yuv-strided, format=(fourcc)NV12, width=176, height=144,
framerate=30/1" ! \
  queue name=q1 ! omx_mpeg4enc \
      profile=1 level=level-2 input-buffers=2 output-buffers=2 bitrate=128000 !
\
  queue name=q2 ! mux.video_0 \
 pulsesrc ! amrnbenc ! queue ! mux.audio_0 0:play  20:eos

or:
gst-auto-launch qtmux name=mux mux.src ! filesink
location=/home/ubuntu/L_SC.CAM2_00029_C.mov omx_camera mode=1 exposure=1 awb=3
ldc=true device=secondary output-buffers=4 name=cam cam.src !
"video/x-raw-yuv-strided, format=(fourcc)NV12, width=176, height=144,
framerate=30/1, buffer-count-requested=4" ! tee name=t t. ! queue name=qenc_in
! omx_mpeg4enc profile=1 level=4 input-buffers=2 output-buffers=2
bitrate=4000000 ! queue name=qenc_out ! queue name=q_v_mux ! mux.video_0 t. !
queue name=q_v4l2 ! v4l2sink device=/dev/video2 min-queued-bufs=2 sync=false
pulsesrc device=input ! audio/x-raw-int,rate=8000,channels=1,width=16 ! faac
profile=2 ! queue ! mux.audio_0 0:play 20:eos

But the real trigger of the issue is that the camera I am using is not giving
me the 30 fps that I am asking for.
