[FFmpeg-user] Sinus error

[Michael Raab]

Little remark on that issue. It happens only with the x64 libaries built 
with vs2010. win32 runs fine.
Do you have any ideas how they may differ?

Thanks,
Michael

Hi,

I've included libav* libraries into our software package. When capturing 
and encoding animations some interpolation calculations (including sin() 
calls) are done in our software.
The error occurs in our source code but is somehow related to libav. If I 
do the same calculations without capturing and encoding everything works 
as expected.
If I use the libav libraries that we used before (built nearly 1 year ago) 

the error does not occur.

Michael

where does this fail? are you using ffmpeg executable or libav*?
