Mina Nagy ZakiandAnton Khirnov 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

Anton Khirnov 472fb3bbfa lavfi: remove some audio-related function from public API. 
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

Anton Khirnov f20ab492ac lavfi: change AVFilterLink.sample_rate from int64_t to int on next bump

Anton Khirnov a6bdfc2a92 lavfi: change AVFilterBufferRefAudioProps.sample_rate from uint32_t to int 
There's no reason for it to be explicitly 32 bits. It's declared as a
plain int in all other places in Libav.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

Stefano SabatiniandAnton Khirnov 7ef0adcc2e lavfi: simplify signature for avfilter_get_audio_buffer() and friends 
The additional parameters are just complicating the function interface.

Assume that a requested samples buffer will *always* have the format
specified in the requested link.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

Stefano SabatiniandAnton Khirnov 6735534f19 lavfi: use avfilter_get_audio_buffer_ref_from_arrays() in avfilter_default_get_audio_buffer 2012-05-09 20:28:56 +02:00
Stefano SabatiniandAnton Khirnov e727bca392 lavfi: cleanup avfilter_get_audio_buffer() and pals. 
Remove AVFilterBufferRefAudioProps.size, and use nb_samples in its place
everywhere.
This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

Also remove the useless planar parameter, which can be deduced from the
sample format.

This is technically an API and ABI break, but since the audio part of
lavfi is not usable now, this should not be a problem in practice.
