Hi All,
I need to write a program that does two things:
1 - It plays digital video stored on disk
2 - Based on info about the digital video, it creates a line chart and displays it on the screen on top of the video image... Such info will be stored on a separate text file or some other data source.
For example, if the digital video lasts for an hour, I would have a text file (or some other data source) with 60 entries, one for each minute of the video. I would then display a line chart on the screen on top of the playing video. Each data point in the line chart will correspond to the entries in the data source. The line chart will be drawn one minute at a time as the video plays, thus the complete chart will be drawn in 1 hour, or whatever the video lasts for. If the video lasts two hours, there would be 120 entries in the data source, each entry containing a data point of the line chart.
The idea is to draw a line chart representing info about the video while the video is playing so that users see both the video and its graph at the same time. Of course, there should be some tranparency in the chart so that it doesn't obstruct the view of the digital video. The beauty of everything will be that the chart is drawn one data point at a time while the video plays...
Any ideas? Thanks...
