2015-05-26avutil: Add av_q2intfloat()Michael Niedermayer
This function allows writing AVRationals as IEEE floats without the need of platform dependant float operations Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2014-01-19lavu/rational: add syntactic sugar.Nicolas George
Add a function to create a rational and macros for common values.
2013-08-27libavutil: cast truncated values to uint32_tAlfred E. Heggestad
programs using ffmpeg that are compiled with -Wshorten-64-to-32 gives a warning when using header files common.h and rational.h cast 64-bit truncated values to (uint32_t) to avoid the warning Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2008-08-31Globally rename the header inclusion guard names.Stefano Sabatini
Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
