[FFmpeg-devel] avdevice/decklink: Fix seg fault in decklink

[BIGLER Don (Framatome)]

Attached is a patch that fixes a potential segmentation fault in avdevice/decklink when used in a multi-threaded environment outside of ffmpeg.  Because the capture_started flag is not set the stream is not closed properly.  This can cause a segmentation fault when the input callback is called in a multi-threaded reader that has not stopped reading before the connection is closed.
