Hi
  Number of platforms:                             1
  Platform Profile:                                FULL_PROFILE
  Platform Version:                              OpenCL 1.2 AMD-APP (1016.4)
  Platform Name:                                 AMD Accelerated Parallel
Processing
  Platform Vendor:                               Advanced Micro Devices,
Inc.


  Platform Name:                                AMD Accelerated Parallel
Processing
  Number of devices:                           2
  Device Type:                                   CL_DEVICE_TYPE_GPU
  Device ID:                                       4098
  Board name:                                    AMD Radeon HD 6700M Series

Also, can you point me to /testfile/blueangles.m4v so I can reproduce
correct and not correct outputs?

about the input file, just a 1080p video, I think you can use anther video
which size is 1080p. You can compile a master branch and run the command in
the mail above.

Thanks
Best regards
