2020-07-02avutil/opt: check return value of av_bprint_finalize()Limin Wang

2020-06-10lavu/opt: add a more general child class iteration APIAnton Khirnov
Use opaque iteration state instead of the previous child class. This mirrors similar changes done in lavf/lavc. Deprecate the av_opt_child_class_next() API.
2020-05-22avutil/opt: add AV_OPT_FLAG_CHILD_CONSTSMarton Balint
This will be used for AVCodecContext->profile. By specifying constants in the encoders we won't have to use the common AVCodecContext options table and different encoders can use the same profile name even with different values. Signed-off-by: Marton Balint <cus@passwd.hu>
2020-05-01avutil/opt: only skip evaluation for rational optionsMarton Balint
Fixes problems when non-rational options were set using rational expressions, causing rounding errors and the option range limits not to be enforced properly. ffmpeg -f lavfi -i "sine=r=96000/2" This caused an assertion failure with assert level 2. Signed-off-by: Marton Balint <cus@passwd.hu>
2020-04-01avutil/opt: Don't use NULL for %s string in a log messageAndreas Rheinhardt
If one calls av_opt_set() with an incorrect string to set the value of an option of type AV_OPT_TYPE_VIDEO_RATE, the given string is used in a log message via %s. This also happens when the string is actually a nullpointer in which case using it for %s is forbidden. This commit changes this by erroring out early in case of a nullpointer. This also fixes a warning from GCC 9.2: "‘%s’ directive argument is null [-Wformat-overflow=]" Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
2020-01-04libavutil/opt: fix memory leak after av_dict_parse_string failJun Zhao
In case of failure, all the successfully set entries are stored in *pm. We need to manually free the created dictionary to avoid memory leak. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Jun Zhao <barryjzhao@tencent.com>

2019-09-21avutil/opt: Print out numeric values of option constantsSoft Works
It's often not obvious how option constants relate to numerical values. Defaults are sometimes printed as numbers and from/to are always printed as numbers. Printing the numeric values of options constants avoids this confusion. It also allows to see which constants are equivalent. Before this patch: -segment_list_type <int> E........ set the segment list type (from -1 to 4) (default -1) flat E........ flat format csv E........ csv format ext E........ extended format ffconcat E........ ffconcat format m3u8 E........ M3U8 format hls E........ Apple HTTP Live Streaming compatible Afterwards: -segment_list_type <int> E........ set the segment list type (from -1 to 4) (default -1) flat 0 E........ flat format csv 1 E........ csv format ext 3 E........ extended format ffconcat 4 E........ ffconcat format m3u8 2 E........

2019-09-21avutil/opt: Fix printing integer option defaultsSoft Works
Integer values should not be printed using format specifier '%g' which leads to inexact display in case of higher values.
