2012-12-05av_assert should use AV_LOG_PANIC.Reimar Döffinger
The description of AV_LOG_PANIC 100% matches what av_assert does, while AV_LOG_FATAL does not really. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
2012-12-02lavu/parseutils: accept %J for hours >= 24.Nicolas George
Allow to parse durations >= 24:00:00.
2012-12-01lavu/opt: allow to set sample and pixel format with av_opt_set_int()Stefano Sabatini
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.
2012-11-30lavu/opt: change the way default pixel and sample format value is setStefano Sabatini
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.
2012-11-26lavu/samplefmt: return the size of the allocated samples buffer at the next bumpStefano Sabatini
Make the functions av_samples_fill_arrays, av_samples_alloc, and avcodec_fill_audio_frame return a buffer size rather than 0 in case of success. This will be enabled at the next libavutil major bump, in order to preserve backward compatibility. Returning the size allows to simplify the code, avoiding a few function calls.
2012-11-25lavu/opt: add support for reading pixel and sample format through av_get_int()Stefano Sabatini
Simplify backward compatibility, when switching from AV_OPT_TYPE_INT to AV_OPT_TYPE_SAMPLE/PIXEL_FMT.
2012-11-25lavu/imgutils: add consistency checks to av_image_copy_plane()Stefano Sabatini
Add assertions and abort in case of invalid |dst_linesize| < bytewidth or |src_linesize| < bytewidth. Avoid to silently corrupt memory.
2012-11-25lavu/opt: add av_opt_ accessors for pixel/format/image size optionsStefano Sabatini
The interface is implemented against the style of the other options accessors. Possibly simplify programmatic setting of options.

2012-10-20lavu/parseutils: rework rational reduction logic in av_parse_ratio()Stefano Sabatini
Avoid to divide num and den by gcd in case of a parsed expression, since that is already done in av_d2q(), and force reduction in case of "a:b" form, allowing to honour the max parameter. The latter change is consistent with the a/b case, and with the documentation.

2012-10-12pixdesc: add functions for accessing pixel format descriptors.Anton Khirnov
Make av_pix_fmt_descriptors table static on next major bump. Making the table public is dangerous, since the caller has no way to know how large it actually is. It also prevents adding new fields to AVPixFmtDescriptor without a major bump.
2012-10-12avutil: Add functions for allocating opaque contexts for algorithmsMartin Storsjö
The current API where the plain size is exposed is not of much use - in most cases it is allocated dynamically anyway. If allocated e.g. on the stack via an uint8_t array, there's no guarantee that the struct's members are aligned properly (unless the array is overallocated and the opaque pointer within it manually aligned to some unspecified alignment).

2012-09-17lavu/parseutils: fix av_small_strptime() whitespace directive parsingStefano Sabatini
According to POSIX, strptime() should consume whitespaces in the date string everytime a whitespace conversion specification is found in the date format specification. Make av_small_strptime() conform with this behavior. In particular, should fix trac ticket #1739.
