memlimit is ignored.

I've noticed while using bmdcapture to pipe capture card input into a video player, if I pause the video player, bmdcapture will fill memory up until the point my system crashes.

The flag -M for memlimit seems to be ignored as well as the 1GB default.

Video demonstrating the problem: http://ks361234.kimsufi.com/bmdcapture.mkv

You can see mpv fill its cache before bmdcapture starts to fill up memory indefinitely well beyond the 1GB limit.

I didn't record it, but after unpausing the video the memory clears itself immediately and bmdcapture stops running after pushing out a few more seconds of video.

I'm using the latest version compiled from this git on Ubuntu 18.04 64 bit with a Blackmagic Design Intensity Pro 4K card.

I'm not sure how the memory in a pipe is accounted for by top

The limit is on the internal frame queue.

Ok, thanks for your reply.

I've been able to limit memory use in another way.
