2010-11-08Use hierarchic names convention (prefix them with av_expr) for theStefano Sabatini
eval API. More grep-friendly and more consistent with the rest of the FFmpeg API. Originally committed as revision 25708 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-05Move eval.c and eval.h from libavcodec to libavutil, and make the evalStefano Sabatini
API public. Originally committed as revision 23485 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-01Make ff_parse_expr() and ff_parse_and_eval_expr() return an intStefano Sabatini
containing an error code. Allow these functions to convey the reason of the failure to the calling function, failure which is not always due to a parsing error but it may depend for example on a memory problem. Also fix several potential memleaks. Originally committed as revision 23402 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-20Change eval API to take parent log context and log level offset.Michael Niedermayer
this is based on stefanos work, especially all bugs are his fault ;) Originally committed as revision 23201 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-17Change the order of parameters for ff_eval_expr() andStefano Sabatini
ff_parse_and_eval_expr(), place the names for constants/functions before the corresponding values. This looks more readable, as the user is expected to know the names before the values. Originally committed as revision 23149 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-12Rename ff_parse() to ff_parse_expr().Stefano Sabatini
The new name is more expressive and fits better in the overall naming scheme for the revisited eval API. Originally committed as revision 22858 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-12Rename ff_parse_eval() to ff_eval_expr().Stefano Sabatini
The new name expresses better what the function does. Originally committed as revision 22844 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-11Rename ff_eval_free() to ff_free_expr().Stefano Sabatini
Originally committed as revision 22834 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun
Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-01-14Change semantic of CONFIG_*, HAVE_* and ARCH_*.Aurelien Jacobs
They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-11-29Implement the fields rc_max_available_vbv_use andBaptiste Coudurier
rc_min_vbv_overflow_use in AVCodecContext, and use their values in the ratecontrol code rather than hardcoded ones. See the thread: "[RFC] ratecontrol buffer size magic". Patch by Baptiste Coudurier. Originally committed as revision 15955 to svn://svn.ffmpeg.org/ffmpeg/trunk
