Alex Converse	b0f29db5c2	Mark mutable static data const where appropriate.	13 years ago
Stefano Sabatini	999495734b	lavu/eval: add if() and ifnot() eval functions They allow to implement the if/then/else logic, which cannot be implemented otherwise. For example the expression: AB + not(A)C always evaluates to NaN if B is NaN, even in the case where A is 0.	13 years ago
Reimar Döffinger	d086c1203c	Add coverage exclusions for test code. For some of the code e.g. doing timing measurements there is no real point in running regression testing on it, thus it should not be counted against coverage. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Stefano Sabatini	d2af7205a1	Use hierarchic names convention (prefix them with av_expr) for the 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	14 years ago
Stefano Sabatini	20fcd0797e	Implement isnan() function evaluation. Originally committed as revision 25666 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	4cabef0a9d	Make strmatch() return 1 only if the string compared against the prefix does not contain other characters which may belong to an identifier. This allows to distinguish for example to have different constants with the same prefix (e.g. "foo" and "foobar"). Originally committed as revision 25626 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	2b59fbe9b1	Add st, ld, while examples/tests. Originally committed as revision 25625 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	8bb12e71af	Add examples of unary operators. Originally committed as revision 25624 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	63b1630356	Fix evaluation of expressions of the form: E1;E2. The pointer to the char ';' has to be increased before to evaluate ";E2". Originally committed as revision 25623 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	eb928286de	Add more tests to eval, help detecting some of the more apparent errors, far from being a complete test system. Originally committed as revision 23635 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	7ec9b9beca	Make av_parse_expr() fail if there are trailing chars at the end of the provided expression. Allow detection of mistyped expressions. Originally committed as revision 23629 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	2f62224bc0	Improve av_parse_eval() error reporting. Originally committed as revision 23627 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	0b99215c0e	Move eval.c and eval.h from libavcodec to libavutil, and make the eval API public. Originally committed as revision 23485 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	79513857ba	Fix eval-test compilation. Originally committed as revision 23406 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	b851dd9e9b	Cosmetics: reindent and break some overly long line. Originally committed as revision 23405 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	0cd28d9494	Cosmetics: consistently apply K&R style. Make me and Diego happy. Originally committed as revision 23404 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	9711439b44	Cosmetics: rename ff_parse_expr() and ff_parse_and_eval_expr() parameters: const_name -> const_names const_value -> const_values func[12]_name -> func[12]_names func[12] -> funcs[12] All these parameters contain a list of values, using plural names for them help understanding a little. Originally committed as revision 23403 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	9ace13b416	Make ff_parse_expr() and ff_parse_and_eval_expr() return an int 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	15 years ago
Michael Niedermayer	2b65bb45b5	Change eval API to take parent log context and log level offset. this is based on stefanos work, especially all bugs are his fault ;) Originally committed as revision 23201 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	edd259f92f	Change the order of parameters for ff_eval_expr() and 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	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Stefano Sabatini	fc7e2d34cf	Fix constness for func[12] parameters in ff_parse_expr() and ff_parse_and_eval_expr(). Change func[12] attributes from "** func" to "* const * func". This is consistent with the semantics of the provided arrays of functions, which are not supposed to be changed by the ff_parse_* functions. Also fix the GCC compilation warnings: libavcodec/ratecontrol.c: In function ‘ff_rate_control_init’: libavcodec/ratecontrol.c:109: warning: passing argument 3 of ‘ff_parse_expr’ discards qualifiers from pointer target type libavcodec/eval.h:69: note: expected ‘double (*)(void , double)’ but argument is of type ‘double (* const)(void , double)’ Originally committed as revision 22860 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
