Stefano Sabatini	334e2e2363	lavu,lavc,lswr: do not hardcode AV_SAMPLE_FMT_NB value when setting sample format max value The constant may change in libavutil but the library may be compiled against an older version, thus rejecting a value which is otherwise supported by the new libavutil. INT_MAX is used here to denote the max allowed value for a sample format. The opt-test code is changed to provide a valid reference example.	11 years ago
Stefano Sabatini	3b8c7da7a3	lavu,lavfi,lavd: do not hardcode AV_PIX_FMT_NB value when setting pixel format max value The constant may change in libavutil but the library may be compiled against an older version, thus rejecting a value which is otherwise supported by the new libavutil. INT_MAX is used here to denote the max allowed value for a pixel format. The opt-test code is changed to provide a valid reference example.	11 years ago
Stefano Sabatini	55f046be11	lavu/opt: apply range checks also when setting format string value Previously when setting a pixel/sample format as a string range checks were not performed. This is consistent with the av_opt_set_pixel/sample_fmt() interface.	11 years ago

Stefano Sabatini	e2b54464c6	lavu/opt: fix range check logic in set_format() In particular, allow to reject undefined values. Previously the code was only accepting values in the range -1 .. NB_FORMATS-1.	11 years ago

Anton Khirnov	0b357a8095	AVOptions: do not range check flag options. It does not make sense in the vast majority of use cases, no currently defined AV_OPT_TYPE_FLAGS options in Libav set the range to anything nontrivial, and many of those get it wrong (the "correct" range is INT_MIN to INT_MAX so that the builtin constant "all" works).	11 years ago

Stefano Sabatini	8696e51baf	lavu/opt: add AV_OPT_TYPE_CHANNEL_LAYOUT and handler functions The new type is compatible with AV_OPT_TYPE_INT64, but allows to specify channel layouts using the format accepted by av_get_channel_layout().	11 years ago
Stefano Sabatini	98e7c1eed5	lavu/opt-test: use automatic set and free handlers In particular, do not set default string value by hand and use av_opt_free() to free context.	11 years ago

Martin Storsjö	c7e921a54f	avopt: Check whether the object actually has got an AVClass AVIOContext has got an av_class member that only gets set if opening the context using avio_open2, but not if allocating a custom IO context. A caller that wants to read AVOptions from an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may not know if the AVIOContext actually has got a class set or not.

Stefano Sabatini	c9ff32215b	lavu/opt: allow to set sample and pixel format with av_opt_set_int() This change requires the user to specify min and max value, and makes possible to prevent the user to set AV_{SAMPLE,PIX}_FMT_NONE if forbidden. Add required ifdeffery in case of mixed libraries, when libavutil is updated but not the other libraries. This is a followup of 08d0969c1402ccec4dce44bd430128fb59d7b790.	12 years ago
Stefano Sabatini	08d0969c14	lavu/opt: change the way default pixel and sample format value is set Use the i64 field rather than the string value. Using a string to set a default sample/pixel format is weird, also the new interface is more consistent with the rest of the API. This is technically an API break, but hopefully there are no applications using this feature outside of FFmpeg. In order to save backward compatibility with mixed libraries in case libavutil is updated but not the other libraries, some ifdeffery hacks are added. Note that the version check is only performed when class->version != 0, since if it is not defined then we assume that no version was defined and the class is not affected by the change. We will luckily get rid of the hack at the next major bump.	12 years ago
Stefano Sabatini	51e9f58e1c	lavu/opt: add support for reading pixel and sample format through av_get_int() Simplify backward compatibility, when switching from AV_OPT_TYPE_INT to AV_OPT_TYPE_SAMPLE/PIXEL_FMT.	12 years ago
