Run doesn't exit with frame_density of 1 #94

Came across this while experimenting with different _framedensity for json comparison. All jsons are produced but the run is stuck at - Waiting for videoDbManagerProcess process to complete.

Looks like we are hitting (1) and (2) described in https://github.com/zigvu/khajuri/issues/87#issuecomment-72309016

With frame density as 1. The steps can be as large as 100 ( since we have 4 video reader processes now )

Since (1) and (2) are not unique to just issue87 i will merge their fixes using this issue.

Fix merged into issue94 branch at 98d5e255c8b2fddfc86a83db3817323a3374ed39. Tested with 14 minute video

Run still getting stuck at end. If this is related to/dependent on #87, can be labled enhancement to be tackled later together.

Not sure, why I don't see this in GPU1.

Waiting for videoDbManagerProcess process to complete.

takes a while but does complete for me in GPU1. Perhaps something specific about GPU2?

arpgh commented 9 years ago

Main difference is that with 4 GPUs, gpu2 has 4 frame extraction threads running. (while gpu1 has 2)
