--- Comment #22 from ykzhao <yakui.zhao at intel.com> ---
Thanks for the testing and response about the patch.

In fact the key problem is caused by that the bit-stream includes some errors,
which doesn't follow the H264 spec. Then the upper-middleware will pass the
incorrect parameter.

The updated patch is mainly to workaround the GPU hang. At the same time it
will try to prompt that the error had better be fixed in the upper-middleware. 

(Of course the previous patch does one smart fix. But it doesn't have the
prompt that the issue should be fixed in the upper-middleware. After the
internal discussion, we think that the updated patch is more reasonable.)

How do you think?
