GST_PADS gstpad.c:3175:gst_pad_query_latency_default:<compositor0:src> minimum latency bigger than maximum latency

To reproduce, download the python script and the test video to the same folder.

Pipeline, for reference:

gst-launch-1.0 playbin uri=file:///trailer.mov \
                       audio-sink=interaudiosink \
                       video-sink=intervideosink \
\
  audiotestsrc ! volume volume=0.1 ! audiomixer name=audiomix caps='audio/x-raw,format=S16LE,channels=2,rate=48000' ! audioconvert ! pulsesink \
\
  interaudiosrc ! audioconvert ! audioresample ! audiomix. \
\
  intervideosrc ! compositor name=videomix caps='video/x-raw,format=I420,width=1280,height=720,framerate=25/1,pixel-aspect-ratio=1/1' ! videoconvert ! xvimagesink


Adding queues after intervideosrc and interaudiosrc fixes it. "The audiotestsrc seems to have a higher min latency than the interaudiosrc has as max latency"

Adding the queues after intervideosrc and interaudiosrc as Tim suggested fixes it.
