Hi Andy,
Are the source vids publicly available anywhere?
Unfortunately no, we couldn’t clear the right for the content we used in our
tests.
Is turing-exe expected to work on non avx CPUs? I just get an illegal
instruction on a Phenom II x4.
Yes we expect it to work on non avx CPUs. Can you please point out what kind of
illegal instruction you get? We can try to fix. Apologies for this.
It may not be avx, I just saw Illegal instruction and assumed.
Whatever I try I can't avoid it, though.
My normal setup is LFS, but I can reproduce on Ubuntu 16.04.
Happens with decode or encode, stable or develop.
With debug builds I can't get a trace with decode.
With encode I managed - but I don't know whether it will be much use as
there may be some variability involved = testing decode with
testdecode --bitstreams
I got a bit further (3 OK) on Ubuntu, than with my normal setup (1 OK).
Anyway here's a partial GDB trace. I couldn't get valgrind to trigger
it, it seemed to get bogged down spewing loads of other errors.
