[root@storm FaceDetect_AVI_WR]# ./facedetect

This program demonstrates the cascade recognizer. Now you can use Haar or LBP features.
This classifier can recognize many kinds of rigid objects, once the appropriate classifier is trained.
It's most known use is for faces.
Usage:
./facedetect [--cascade=<cascade_path> this is the primary trained classifier such as frontal face]
   [--nested-cascade[=nested_cascade_path this an optional secondary classifier such as eyes]]
   [--scale=<image scale greater or equal to 1, try 1.3 for example>]
   [--try-flip]
   [filename|camera_index]

see facedetect.cmd for one call:
./facedetect --cascade="../../data/haarcascades/haarcascade_frontalface_alt.xml" --nested-cascade="../../data/haarcascades/haarcascade_eye.xml" --scale=1.3

Hi,

If you care to describe how you solved this issue, please let us know. It could be of interest to the general OpenCV community.

Thank you!

well, you don't need to worry about this problem and you may never encounter such situation without GFW.
I suppose almost no one from mainland China. If you are, try this:
install the following packages MANUALLY :
gstreamer1-vaapi-0.5.8-5.el7.nux
gstreamer1-libav1.0.6-1.el7.nux.x86_64
gstreamer1-vaapi-devel-0.5.9-3.el7.x86_64
the above packages automatic on-line installing is blocked by GFW, and I just tried it in CentOS7.1, if it doesn't works in you system, just prayer...
