[QUOTE="henso, post: 1158227, member: 119106"] The TranscodingService metadata extractors uses the MediaAnalyzer which again uses the following code: [CODE=C#]ProcessExecutionResult executionResult; lock (FFPROBE_THROTTLE_LOCK) executionResult = FFMpegBinary.FFProbeExecuteWithResourceAccessAsync(lfsra, arguments, ProcessPriorityClass.Idle, AnalyzerTimeout).Result;[/CODE] Looks familiar?
