Yes, both work.

It fails with all ac3 samples, 5.1, 2.1, 2.0 (monsters_inc_2.0_192.ac3,
all samples from http://samples.mplayerhq.hu/A-codecs/AC3/).
With TomorrowNeverDies-2.1-48khz-192kbit.ac3, but only with this one,
I even get some errors:
[ac3 @ 0x9d0e620] frame sync error
Error while decoding stream #0:0: Operation not permitted
[ac3 @ 0x9d0e620] frame CRC mismatch
There are no error messages with the other samples.
