Yes the idea is to run the command asynchronously so we can monitor the transcode progress and kill it if it stops making progress. Calling pcntl_waitpid with pcntl_fork as Tim mentions may be the way to get it done. With the child including the pcntl_waitpid call and the parent monitoring "progress" and killing the child if need be. --michael _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
