How about using "MFXCloneSession()" to shorten these codes?
In fact, for Linux, "MFXJoinSession()" probably fails here because the
parent_session has the version of {3, 1} (see hwcontext_qsv.c),
but the child_seesion has the version queried by "MFXQueryIMPL", which
always returns the version of current libmfx, such as {20, 1}.
It is worth a try for sure, thank you!
Looks like trying to Clone the session results in something strange at
least on the version of mediasdk on my test system.
