* lavfi: add priv class to filter definitions and flags to filter internal optionsStefano Sabatini2012-08-18
| | | | | This allows the iteration callbacks to discover the internal class and options, and show them when required.
* Remove "Error parsing options string [...]" messages.Clément Bœsch2012-08-09
| | | | | This reduces from 3 to 2 messages for the same syntax error in ffprobe, and from 4 to 3 in filters.
* lavfi: do not pass opaque field to init functionsStefano Sabatini2012-07-08
| | | | Fix signature mismatch warnings.
* lavfi: define macro AVFILTER_DEFINE_CLASSStefano Sabatini2012-06-22
| | | | | The macro can be used to define consistently the internal class of a filter, save some typing and factorize.
* lavfi: remove redundant checks after av_parse_video_rate()Paul B Mahol2012-06-20
| | | | Signed-off-by: Paul B Mahol <onemda@gmail.com>
* lavfi: use designated initializers for AVClassPaul B Mahol2012-06-17
| | | | | | | | | While here: - add missing .version and .category, - make .class_name consistent across filters, - align declarations. Signed-off-by: Paul B Mahol <onemda@gmail.com>
* lavfi: update some deprecated functionsPaul B Mahol2012-06-16
| | | | Signed-off-by: Paul B Mahol <onemda@gmail.com>
* lavfi: use av_default_item_name() as filter private context loggerStefano Sabatini2012-06-04
| | | | | | avfilter_default_filter_name() is supposed to access an AVFilterContext struct, if used with a private struct it will cause a crash since it will access fields which are non defined in the private struct.
* lavfi: add avfilter_default_filter_name()Stefano Sabatini2012-06-04
| | | | | | | | The function is modelled after av_default_item_name(), and will print the name of the instance filter if defined, otherwise the name of the filter. This allows to show the instance name in the log, which is useful when debugging complex filter graphs.
* vsrc_mandelbrot: use AV_OPT_TYPE_IMAGE_SIZE.Nicolas George2012-05-20
|
* lavfi: fix mp and mandelbrot descriptions to make them complete sentencesStefano Sabatini2012-01-21
| | | | This is consistent with the other filter descriptions.
