AVBufferSrcParameters

This structure contains the parameters describing the frames that will be passed to this filter.

It should be allocated with av_buffersrc_parameters_alloc() and freed with av_free(). All the allocated fields in it remain owned by the caller.

struct AVBufferSrcParameters {

AVRational time_base;

AVRational sample_aspect_ratio;

AVRational frame_rate;

AVBufferRef* hw_frames_ctx;

int sample_rate;

ulong channel_layout;

Members

Variables

channel_layout ulong channel_layout;: Audio only, the audio channel layout
format int format;: video: the pixel format, value corresponds to enum AVPixelFormat audio: the sample format, value corresponds to enum AVSampleFormat
frame_rate AVRational frame_rate;: Video only, the frame rate of the input video. This field must only be set to a non-zero value if input stream has a known constant framerate and should be left at its initial value if the framerate is variable or unknown.
height int height;: Undocumented in source.
hw_frames_ctx AVBufferRef* hw_frames_ctx;: Video with a hwaccel pixel format only. This should be a reference to an AVHWFramesContext instance describing the input frames.
sample_aspect_ratio AVRational sample_aspect_ratio;: Video only, the sample (pixel) aspect ratio.
sample_rate int sample_rate;: Audio only, the audio sampling rate in samples per second.
time_base AVRational time_base;: The timebase to be used for the timestamps on the input frames.
width int width;: Video only, the display dimensions of the input frames.
