Hey Alex, thx for the reply. You hit one of the magic words ("aligned") that
I'm investigating further. I've seen "align" as a parameter in a number of the
avcodec function calls, and there doesn't appear to be much discussion
regarding the proper setting of this value (like for example "0 = default" --
which doesn't explain what the "default" actually means). Also understand that
alignment even in audio samples has other interpretations, so I'm trying to
make sure I'm not reading something into what FFmpeg means by this.
So back to your statement that "both data[0] and data[1] must be aligned". What
specifically do you mean by this?
Thanks,
Brad
