Vic Dumper

With my previous modifications to Open Mash, I can have vic dump RTP packets and YUV frames to disk. The rtp-recast program will recast those RTP packets with the correct interframe delay. But for this to be fully automated, I need a non-GUI version of vic that can be launched (or kept running) and automatically dump the received video as YUV frames to disk for comparison by the VQM Software.

So I started working on a Open Mash application I'm calling Vic Dumper (vicdump) that will do this. I'm basing the Tcl code, which will use smash instead of mash, on a combination of the vic, rvic, and rvic-cl code. That should let vicdump handle the receipt of video streams. The one thing I'm not sure about is whether or not Open Mash will stop dumping frames to disk once it has stopped receiving frames. I think it would, since the decoder would no longer be called and the image buffer is no longer updated.

Since it looks like I'll have to wait a while on the Linux VQM Software and the stock video footage, this is what I can work on for now.
