slow readVideoComponent() due to volumedetect in getFileRawInformation()

[tsmgeek]

I am using readVideoComponent() to ultimately get the video resolution/SAR/DAR etc, this should be a quick task but not due to the underlying getFileRawInformation() doing "-af volumedetect".
I understand this is required for audio info and also for abstraction you are doing it in one action but its a killer to processing speed.
Cant the getFileRawInformation be split in two so for simple tasks like getting dims etc its quick.
