RE: Error messages at creation/deletion of codec instances
Chris, Thanks again, I have gone through that link. I opening engine in one thread then I pass that handle to other thread (coder thread) as an argument. That thread uses engine handle in serialized manner. So my use case is still valid. What can be the reason for these errors? As Chris said, it will be great if some more familiar with the issue can jump in.

Your use case is supported. I'll ask you to review this thread here as
there are some things to be careful about:

RE: Error messages at creation/deletion of codec instances
Chris,
Thanks for your reply.
I have single process - multithreaded application.
I am opening engine in _main ()_ function of my application.
I am creating a thread to perform coding & in this coding thread I am
creating codec instances. This coding thread will be created as and when
needed.
So I am opening engine one thread and creating codec instances in other
thread.
Is it creating any problems?
Kushal

Are you using multiple processes in your app?
I'm not a Link expert, but I think these assertions are thrown when you
call MSGQ_Get() (which the internals of the VIDENC_create()/delete()
APIs use) from a different process than you called MSGQ_Open() with
(which Engine_open() does).
(Link experts please correct me)
If that's the case, Codec Engine doesn't currently support multiple
processes - it does support multiple threads within the same process...
but not multiple processes.
Some details on your app's threading model might help. I haven't seen
these assertions thrown before.
