I'm just making some experiments with the drawgraph filter and it took
me more than one hour to figure out what was wrong:
The colors of the graphs must be specified in format 0xAABBGGRR, but the
background color must be in format 0xRRGGBBAA.
That's very confusing!
Sounds like a bug to me but changing the code will break existing scripts;-(
Well, in the documentation is a chapter about colors and the format is
described as 0xRRGGBB[AA].
However in the documentation for the drawgraph filter is written "The
color is defined as 0xAABBGGRR". So it's impossible to use the
predefined colors in this filter.
In the documentation should be a warning that the "bg" parameter must be
in 0xRRGGBBAA format.
But in my opinion changing the code is the better solution.
