I just finished packaging up the software for the VQM Oracle. I cannot include any of the library files used by our server, or the VQM Software, and I've only included the relevant Open Mash binaries. I finished the watcher script that will make sure the server and oracle processes stay up, and created README and NOTES documentation.
At this point, I'm basically done with everything. Unless reports of erroneous behavior come back from Vinay Chandrasekar at NC State, the only thing left to do is transfer these files to the NCNI server when it arrives.

Yesterday I re-dumped all the NCNI sequences in H.261 format. I didn't do them in M-JPEG this time, since the NC State client program is only sending H.263 requests. So now the VQM Oracle is up and running just fine.
I started packaging the VQM Oracle software up as well. I need to finish up some more documentation and create the cronjob watcher script that will keep the server and oracle processes up and running, but once that's done everything should be complete.

Corrupt Frame Dumps & MPEG-2 Playback
I tracked down the problem with my VQM Oracle setup. A whole bunch of frames in the frame dumps were corrupted because I had used fprintf with a "%s" format string. This ended up not dumping out the entire frame because zero values would show up in the middle of a frame. I changed it to fwrite and everything works. But now I need to re-dump the NCNI sequences that Tyler Johnson got for me.
I also tried to run an MPEG-2 video clip through the Java MPEG-2 parsing classes that Ketan sent me, but I couldn't figure out how to playback the video clips I found on the Internet. I want to make sure I can do that so I know what I'm parsing.

Oracle Running; VQM Error
I've spent the past couple of days putting together the automatic processing script for the VQM Oracle. The server and oracle scripts I've written work fine, however the VQM Software itself is choking on the data files. I'm getting the following error:
Set By: cntl_file scan_line
Message: Reading Data File
File Format corrupted, line missing
I need to track down the problem and fix it.
