[Libquicktime-devel] FFMpeg thread safety

[Derek C. <der...@mi...>]

Hi,

FFMpeg usage should use register a lock manager with 
av_lockmgr_register() so that multithreaded use of libavcodec can mutex 
critical sections and avoid errors such as "Insufficient thread locking 
around avcodec_open/close()" in the FFMpeg plugin.

See attached patch for a suggestion (based on 
http://code.opencv.org/issues/1369) on how this could be addressed.

Cheers,
Derek
