EAGAIN is sometimes convenient in a demuxer instead of a loop or
goto retry

The theoretical advantage of EAGAIN is in case of a long stream of
unsupported packets. Where otherwise the demuxer may be locked for a
long time.

but as you mention it now, i do also realize that its semantically not
exactly correct to use EAGAIN for this.
