I don't get that warning and using \ aligns with the Windows file system.

Your file is an old version. The new version of the file I use will report an error.

Then use the version I included. Secondly it's not an error, it's a warning. It appears from your output that it still worked and created an image.

Now while you shouldn't always ignore warnings, it appears at least in this case that it's not really an issue to worry about.

At the framerate your video is at the video is too long. The Stab table is bigger than what's allocated. Split it into multiple files.

But my frame rate is more less than 30 fps...23.976 for exacly. "Split it into multiple files." OK...thanks.

Your video is 24fps, and about 6:30 long. That's 9,360 frames in the video. All of those frames and the audio samples have to be accounted for in the STAB chunk. As a result your STAB chunk is taking up about 170KB of RAM and bleeding into other areas. If you read the official documentation it says you should consider splitting your videos up if you go beyond 5-7 minutes in length depending on the frame rate. When I did How the Grinch Stole Christmas I was at 15fps and never took a video beyond 7 minutes. My stab chunks at that frame rate had about half of what yours have.

That's because your player has smaller buffers for video and audio which prevents it from going up to 320x240 resolution as well as pushing higher audio quality. As a result there's a little more memory to play with for the STAB chunk. Since my player has larger buffers to accommodate larger resolutions, higher audio quality, etc. the STAB chunk is bleeding into other variables and causing decompression to fail.

That all said, I went and did some clean up and rearranged some things to increase the Ring Buffer size to allow for larger STAB chunks.
