Memory error

[tsalo]

We got a memory error when running the task on the stim PC.

Perhaps we can downsample the S01E01-S01E06 run videos. S01E07-S02E01 are pretty small compared to the early episodes, so if we can get the resolution from those and use that resolution for the older, high-res ones, then maybe that can fix it....

I'm reprocessing all stimuli to have a width of 720 pixels so hopefully that will help.

The reprocessing decreased file size substantially (e.g., a 2.1G clip went down to 662M). We'll have to try it out at the scanner to make sure it works though.

Same problem. Full clip runs successfully but then at the end a black screen stays up instead of moving to the fixation and after a while a memory error occurs.

EDIT: Not sure if the version run on the smaller video files is a memory error. Seems to be a problem with the size setting that I was doing.

It looks like this was the result of trying to present a frame after the end of the video. 0d5758c should deal with this.

I was sure I'd fixed it, but it recently failed again on the stimulus computer in the exact same way.

Which runs it fails on seem to be completely random. One day it fails on runs 1, 2, 3, and 4 (of 6) and the next it only fails on 4 (with the same stimuli!).
