Function Documentation

AVABufferSinkParams* av_abuffersink_params_alloc ( void   ) 

Create an AVABufferSinkParams structure.

Must be freed with av_free().

int av_buffersink_get_buffer_ref ( AVFilterContext buffer_sink,
AVFilterBufferRef **  bufref,
int  flags 
)

Get an audio/video buffer data from buffer_sink and put it in bufref.

This function works with both audio and video buffer sinks.

Parameters:
buffer_sink pointer to a buffersink or abuffersink context
flags a combination of AV_BUFFERSINK_FLAG_* flags
Returns:
>= 0 in case of success, a negative AVERROR code in case of failure
