OverflowException in AviWriter.WriteFileHeader

[schindlerma]

There is a System.OverflowException in AviWriter.cs line 632 in the WriteFileHeader method when using larger values for FramesPerSecond, like 1000.

SharpAvi/SharpAvi/Output/AviWriter.cs

Line 632 in b86f69d

fileWriter.Write((uint)Decimal.Truncate(FramesPerSecond * streamsInfo.Sum(s => s.MaxChunkDataSize))); // max bytes per second

So, what is the correct way to calculate the byterate?

Hi @schindlerma
I wonder in the first place do you really use such high frame rates and what for? Does any video player support such frame rates?

So, what is the correct way to calculate the byterate?

Sorry, not sure what I meant here after the years passed. I guess it's about calculating the (average or maximum) byterate from actual data written to a file. And updating it in the header when the file is being closed.

Hi @baSSiLL

Yes, the high frame rates are not just theoretical, they are actually used in videos from high speed cameras.
The video players I use can handle them, e.g. VLC, Windows MediaPlayer.
