Issue Description

I recorded a video using the camera and when I try to extract the frames using rs-convert, it works as expected when trying to convert to PNG but if I specify the -l option to convert to PLY nothing happens. It executes for a few seconds and then exits without saving anything. Generated log files are also empty. Same behaviour is observed when trying to convert to BIN or CSV with the only difference being it outputs the number of frames processed but nothing is saved.

I already tried it by saving the file in different locations so it does not look like a permissions issue.
