Are you testing the h264 video clips on Sandybridge or Ivybridge? Does
the issue happen on every h264 clips or some specific clips?

Will you please describe the issue more clearly for the H264 decoding?
     For example: the dump info and dmesg info when triggering the glibc
memory corruption erros and so on.

Thanks.
