[FFmpeg-cvslog] pthread: Immediately release all frames in ff_thread_flush()

[Alexander Strange]

ffmpeg | branch: master | Alexander Strange <astrange at ithinksw.com> | Sat Mar 24 18:25:15 2012 -0400| [147ee4cf065a20bbba10292b496a037e6573cd6e] | committer: Ronald S. Bultje

pthread: Immediately release all frames in ff_thread_flush()

Before this, they were only added to the delayed release queue and not
freed until later. This could lead to unnecessary memory use or buffer
exhaustion.
