41e637e449 lavfi: Add the af_channelmap audio channel mapping filter. 
Inspired by MPlayer's af_channels filter and SoX's remix effect.
 2012-06-22 13:55:58 -07:00

dc07fb6f7b lavfi: add join audio filter. 
It joins multiple input streams into one multi-channel output.

f75be9856a lavfi: allow audio filters to request a given number of samples. 
This makes synchronization simpler for filters with multiple inputs.
 2012-06-22 21:23:42 +02:00

58b049f2fa lavfi: support automatically inserting the fifo filter when needed. 
This breaks libavfilter ABI.

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.

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.

4a97ff2fa7 lavfi/fifo: add audio version of the fifo filter. 2012-06-21 07:38:35 +02:00

394a2a0452 lavfi: rename vf_fifo.c -> fifo.c 
It will be used for audio too.

9baeff9506 lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs 
This is more consistent with naming in the rest of Libav.

9d0bfc5052 lavfi: make AVFilterPad opaque after two major bumps. 
It will allow adding new fields to it without ABI breaks.
 2012-06-13 11:11:33 +02:00
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.

6d58358a3a lavfi: make avfilter_get_video_buffer() private on next bump.

now.

c04c533f62 lavfi: remove avfilter_null_* from public API on next bump. 
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

43c7a01e98 lavfi: remove avfilter_default_* from public API on next bump.

88c3b87bd8 lavfi: deprecate default config_props() callback and refactor avfilter_config_links() 
Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.

Remove now empty defaults.c
