ffmpeg | branch: release/1.0 | Clément Bœsch <ubitux at gmail.com> | Fri Oct 12 18:23:46 2012 +0200| [09c79d50d88eada370489dac520e127aa56cf841] | committer: Clément Bœsch

lavf/swfdec: fix flushing with compressed swf.

We now only return in the middle of the refill in case of read error, so
inflate can be re-called if zlib needs an empty (z.avail_in=0) inflate
call for flushing.
