Description Eunhae Choi 2015-12-23 12:37:45 UTC 
When we test ... - avdec_h264 - shmsink pipeline, avdec try to alloc too many buffers(upto 32 buffers) with buffer pool even we set shm-size on shmsink.

If we try to play FHD movie on our target, the operation is stopped after a while by lack of memory. 

We thisnk the max size of buffer pool needs to be set to avoid this issue.
You can check the issue with below lauch cmd.

# gst-launch-1.0 filesrc location=./s.mp4 ! qtdemux ! h264parse ! queue ! avdec_h264 ! shmsink socket-path='/tmp/mused_gst.5' wait-for-connection=false sync=true perms=0777

I am making a patch for this issue and it is about setting limitation of max-buffers of buffer pool based on the shm-size property.
