Stefano Sabatini	1dce2368bb	lavfi/buffer: apply misc consistency nits	13 years ago
Stefano Sabatini	c17808cebd	lavfi: define macro AVFILTER_DEFINE_CLASS The macro can be used to define consistently the internal class of a filter, save some typing and factorize.	13 years ago
Stefano Sabatini	012aa12a6b	lavfi/drawtext: remove unnecessary parentheses in init()	13 years ago
Alex Converse	41e637e449	lavfi: Add the af_channelmap audio channel mapping filter. Inspired by MPlayer's af_channels filter and SoX's remix effect.	13 years ago
Anton Khirnov	dc07fb6f7b	lavfi: add join audio filter. It joins multiple input streams into one multi-channel output.	13 years ago
Anton Khirnov	f75be9856a	lavfi: allow audio filters to request a given number of samples. This makes synchronization simpler for filters with multiple inputs.	13 years ago
Anton Khirnov	58b049f2fa	lavfi: support automatically inserting the fifo filter when needed. This breaks libavfilter ABI.	13 years ago
Anton Khirnov	fa06623930	lavfi/audio: eliminate ff_default_filter_samples(). It currently does the following: 1) get a zeroed audio buffer 2) copy some properties (but not the data) of the input buffer to it 3) pass this buffer to the output filter This looks useless and is indeed not used by any filters, therefore delete it. Make ff_null_filter_samples() (just pass the buffer to the next filter) the new default.	13 years ago
Stefano Sabatini	1bb30d0295	lavfi/deshake: fix crash in uninit() Add NULL check on avctx before calling avcodec_close() on it. Fix trac ticket #1472.	13 years ago
Stefano Sabatini	cb08b6efc9	lavfi/scale: remove unused variable out_link Fix warning: libavfilter/vf_scale.c: In function ‘start_frame’: libavfilter/vf_scale.c:284:23: warning: unused variable ‘out_link’ [-Wunused-variable]	13 years ago
Stefano Sabatini	c0b3c0ffb7	lavfi/audio: remove unused variable in ff_filter_samples() Fix warning: libavfilter/audio.c: In function ‘ff_filter_samples’: libavfilter/audio.c:193:13: warning: unused variable ‘size’ [-Wunused-variable]	13 years ago
Stefano Sabatini	98701be356	lavfi/ass: update use of deprecated functions, fix warnings	13 years ago
Stefano Sabatini	eda4500866	lavfi/blackdetect: add logic for handling stream termination Add request_frame() which checks the black duration when the end of the stream is signalled. Allow to detect black video segments at the end of the stream. Note that the reported last black video segment duration is not very accurate, since we still miss the duration information in the video buffer. Address trac ticket #1470.	13 years ago
Stefano Sabatini	5bc87f1cd6	lavfi/blackdetect: fix pts time debug printing	13 years ago
Anton Khirnov	e026c9b390	lavfi/audio: don't set cur_buf in ff_filter_samples(). It's redundant, since the input buffer is passed as a parameter to the filter_samples() callback, and can lead to stale pointers remaining on the link.	13 years ago
Anton Khirnov	4a97ff2fa7	lavfi/fifo: add audio version of the fifo filter.	13 years ago
Anton Khirnov	27570e211a	fifo: fix parenthesis placement.	13 years ago

Stefano Sabatini	3ea3e32e03	lavfi: add showwaves filter	13 years ago
Stefano Sabatini	93bbe53c44	lavfi/asplit: fix memleak The input samples buffer must be unreferenced after it is propagated to the output links.	13 years ago
Paul B Mahol	10952e0602	lavfi/color: fix typo Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Paul B Mahol	9e7543361c	lavfi/color: use AVOptions Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Pavel Koshevoy	5fa8226420	libavfilter: improve atempo audio quality Reduce audio fragment alignment jitter by penalizing alignment correction offsets that deviate too much from the target offset. This is accomplished by multiplying the cross correlation search window with a quadratic function. Signed-off-by: Pavel Koshevoy <pavel@homestead.aragog.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	0412e5187e	lavfi/avfilter: use av_assert Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	db142a8395	lavfi/avcodec: make avfilter_fill_frame_from*() functions use avfilter_copy_buf_props() The code in avfilter_copy_buf_props() is more generic, allow code factorization.	13 years ago
Stefano Sabatini	8f8d8b9538	lavfi/avcodec: always use av_frame* accessors in avfilter_copy_buf_props() Use av_frame_* accessors for the newly added fields in AVFrame (for which we are supposed to use such accessors), and group the istructions accordingly.	13 years ago
Stefano Sabatini	d5761fe47d	lavfi/avcodec: copy pos field from AVFilterBuffer to AVFrame pkt_pos	13 years ago
Justin Ruggles	ae46fbee1d	af_amix: allow float planar sample format as input	13 years ago
Justin Ruggles	f0ece49e74	af_amix: use AVFloatDSPContext.vector_fmac_scalar()	13 years ago
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
