Paul B Mahol	54101214d8	lavfi: use designated initializers for AVClass While here: - add missing .version and .category, - make .class_name consistent across filters, - align declarations. Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Pavel Koshevoy	a1aac8d004	lavfi: add atempo filter Add atempo audio filter for adjusting audio tempo without affecting pitch. This filter implements WSOLA algorithm with fast cross correlation calculation in frequency domain. Signed-off-by: Pavel Koshevoy <pavel@homestead.aragog.com> Signed-off-by: Stefano Sabatini <stefasab@gmail.com>	13 years ago
Paul B Mahol	c9e183b490	lavfi: update some deprecated functions Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Paul B Mahol	fd8def9248	lavfi/super2xsai: fix fate test on bigendian Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Michael Niedermayer	46c50b1726	vf_pad: check that we have write permission before writing in the buffer. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	2b1fc5621d	lavfi: add asetnsamples audio filter This filter changes the number of samples on single output operation. Based on a patch by Andrey Utkin <andrey.krieger.utkin@gmail.com>.	13 years ago
Stefano Sabatini	e20530add7	lavfi/split: give a more accurate description to split The filter now supports a configurable number of outputs.	13 years ago
Stefano Sabatini	b2bcbcd999	lavfi/super2xsai: simplify code updating the color matrix at each y iteration Remove duplicated out-of-loop init code, and do color matrix initialization at the beginning of each y iteration. Allow factorization and avoid an useless matrix update in the last iteration.	13 years ago
Stefano Sabatini	4ebb46eb14	lavfi/super2xsai: fix table used to update color matrix at the end of each y loop The previous table appears to be wrong (it was copied from the original MPlayer super2xsai filter in order to keep binary compatibility). The new table is consistent with the init code and apparently fixes a combing artifact on the left edge of the generated image.	13 years ago
Stefano Sabatini	635a25954e	lavfi/video: set output frame w/h properties in default_start_frame() Use the same values of the video output link. Avoid the need to override the default_start_frame() with an ad-hoc start_frame() callback. In particular, fix the super2xsai filter which was setting the input w/h values in the output.	13 years ago
Stefano Sabatini	f0394f28c3	lavfi/avcodec: add consistency checks in avfilter_copy_buf_props() The function will abort through an assert if the source is not defined, or if the internal state of the source is inconsistent (e.g. type = AUDIO && !src->audio).	13 years ago
Janne Grunau	fbc5740566	af_resample: fix format modifier in debug string for FF_API_SAMPLERATE64	13 years ago
William Yu	f77a695d2e	lavfi: af_amerge options array was not ended with NULL Add a NULL to prevent undefined behavior Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	9cdf74f904	lavfi/audio: use av_samples_copy() instead of custom code. Fixes a possible invalid write, found by Nicolas George.	13 years ago
Anton Khirnov	24b2f4ed21	avfiltergraph: remove a redundant call to avfilter_get_by_name().	13 years ago
Anton Khirnov	2f296e39a1	lavfi: allow building without swscale.	13 years ago
Anton Khirnov	9baeff9506	lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs This is more consistent with naming in the rest of Libav.	13 years ago
Anton Khirnov	9d0bfc5052	lavfi: make AVFilterPad opaque after two major bumps. It will allow adding new fields to it without ABI breaks.	13 years ago
Anton Khirnov	84b9fbe055	lavfi: add avfilter_pad_get_type() and avfilter_pad_get_name(). This will allow making AVFilterPad opaque for the calling apps, since those are the only two fields that can be useful to the users.	13 years ago
Anton Khirnov	6d58358a3a	lavfi: make avfilter_get_video_buffer() private on next bump. They are only useful inside filters and we don't allow user filters for now.	13 years ago
Stefano Sabatini	465a72b4b4	lavfi: move definition of avfilter_copy_buf_props() from buffer.c to avcodec.c avcodec.c is where it is defined the lavc/lavfi interface code, so seems a more adequate location (and doesn't force the inclusion of libavcodec/avcodec.h where it is not required).	13 years ago
Stefano Sabatini	134815a030	lavfi: change name of tracing functions and of the macro which enables them The enabling symbol is renamed FF_AVFILTER_TRACE. Avoid conflicts with the DEBUG macro, which may be defined for different purposes.	13 years ago
Anton Khirnov	d625136877	lavfi: add channelsplit audio filter.	13 years ago
Alex Converse	65a80ee1ec	avfilter: Log an error if avfilter fails to configure a link.	13 years ago
Stefano Sabatini	ee1748ab53	lavfi: fix signature for default_filter_name() Return a const char *, fix warnings: libavfilter/avfilter.c: In function ‘default_filter_name’: libavfilter/avfilter.c:414:5: warning: return discards ‘const’ qualifier from pointer target type [enabled by default] libavfilter/avfilter.c: At top level: libavfilter/avfilter.c:419:5: warning: initialization from incompatible pointer type [enabled by default] libavfilter/avfilter.c:419:5: warning: (near initialization for ‘avfilter_class.item_name’) [enabled by default]	13 years ago
Nicolas George	0d24931604	vf_fps: set frame_rate.	13 years ago
Nicolas George	c8428a0d06	vf_tile: update deprecated functions.	13 years ago
Nicolas George	7b993c4a51	vf_tile: set frame_rate.	13 years ago
Anton Khirnov	d7d071a673	vf_libopencv: add missing headers. Fix build after `b74a1da4`.	13 years ago
Michael Niedermayer	d35c27db63	sink_buffer: dont return void from void functions. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	7b0d362567	libavfilter: make ff_null_start_frame_keep_ref() a non static inline function. Its only used through the start_frame pointer and thus cannot be inlined easily. It also appears to break compilation with some unidentified compiler on darwin. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	0f62125643	buffersrc: deprecate flat options syntax.	13 years ago
Nicolas George	9ca440679d	buffersrc: accept the frame rate as argument.	13 years ago
Nicolas George	dcaa4efcee	buffersrc: accept key=value arguments. The current flat arguments syntax is not easily extensible due to sws_param possibly containing commas. This is also consistent with abuffersrc.	13 years ago
Nicolas George	283cc05938	buffersink: add av_buffersink_get_frame_rate().	13 years ago
Nicolas George	7b42036b3b	lavfi: add a frame_rate field to AVFilterLink.	13 years ago
J. Bohl	023c073076	add bracket around the argument (fixes compilation error with ICL) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	e0545262a2	amerge: accept multiple inputs.	13 years ago
Nicolas George	e8e492b302	af_amerge: move nb_in_ch into the in structure. With that change, there is only one array for the inputs, it will make easier to implement a variable number of inputs.	13 years ago
Nicolas George	9915a33fc2	lavfi/audio: fix size of copied samples. Fixes sporadic segfaults with some filters.	13 years ago
Stefano Sabatini	ad347bf459	lavfi: remove avfilter_default_item_name() from public API The function was introduced in `4d6a8a2bdb` and is not used anymore outside avfilter.c. This avoids to pollute the public API with an apparently unnecessary function. The function was introduced a few days ago, so removing it from the public API should do no much harm.	13 years ago
Stefano Sabatini	fe16ca1b91	lavfi/ocv: fix compilation after internalization of public functions Include missing required internal headers.	13 years ago
Stefano Sabatini	647e2e070f	lavfi: remove more instances of avfilter_default_filter_name() They were discarded in `0f0f3bd1e0`.	13 years ago
Stefano Sabatini	0da9bce5a3	lavfi: move avfilter_copy_frame_props() definition from buffer.c to avcodec.c The new location is more suited, as it is where the lavfi/lavc glue is defined.	13 years ago
Andrew Wason	c527027c27	aconvert filter needs to configure samplerates I changed the _set_common_ functions to only set unset formats, then added a wrapper that calls them after the filters query_formats. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	aba8065adb	avfiltergraph: call query_formats on inputs first. This is a temporary workaround for amerge, until format renegociation is implemented. Should fix trac ticket #1400.	13 years ago
Nicolas George	6a4c5c730e	avfiltergraph: check query_formats return value.	13 years ago
Stefano Sabatini	1488c4dc0b	lavfi: move tracing utilities definition from video.c to avfilter.c These utilities are meant to be defined in avfilter.c, since they are generic and thus contain both audio and video code.	13 years ago
Anton Khirnov	803391f719	lavfi: remove request/poll and drawing functions from public API on next bump They are only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	fa417fcd27	lavfi: make avfilter_insert_pad and pals private on next bump. They are only useful inside filters and we don't allow user filters for now.	13 years ago
