Lukasz Marek	3aac5fcfa9	lavu/opt: validate range before dereference This change make error handling simplier. av_opt_freep_ranges may be called when some ranges are NULL, for example after memory allocation fail. Signed-off-by: Lukasz Marek <lukasz.m.luki@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Lukasz Marek	8c27292373	lavu/opt: dont crash on freeing NULL AVOptionRanges Signed-off-by: Lukasz Marek <lukasz.m.luki2@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Lukasz Marek	eaed4da96a	lavu/opt: extend AVOptionRange by extra values AVOptionRange is not flexible enough to store AV_OPT_TYPE_IMAGE_SIZE ranges. Current implementation can only store pixel count. This patch aims to keep backward compatibility and extend AVOptionRange with possibility to store width/height ranges. Signed-off-by: Lukasz Marek <lukasz.m.luki@gmail.com>	11 years ago
Michael Niedermayer	d9a3501c33	avutil/opt: dont crash on av_opt_set_dict() with NULL This allows calling the function without the need to check if the dictionary contains any entries Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	52d928daf9	avutil/opt: allow max=min=0 for pixel formats This is neccessary for maintaining ABI compatibility with FFmpeg 2.1 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	c3ecd968f0	AVOptions: add flags for read/read-only options	11 years ago
Michael Niedermayer	8f853159f6	avutil/opt: preserve fractions in set_string_number() This avoids going over a double precission float, which may loose precission Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
João Bernardo	290326711b	avutil/opt: Better print representation of number limits Signed-off-by: João Bernardo Oliveira <jbvsmo@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
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	1575a96b3a	lavu/opt: factorize setting of format values from string Simplify incoming patch.	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

Michael Niedermayer	162126bb17	avutil/opt: check flags validity in write_number() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Michael Niedermayer	2d8ccf0adc	avutil/opt: initialize ret Fixes CID1108610 Fixes use of uninitialized variable Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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.
