Detailed Description

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.

Member Data Documentation

◆ channel_layout

uint64_t AVBufferSrcParameters::channel_layout

Audio only, the audio channel layout

◆ format

int AVBufferSrcParameters::format

video: the pixel format, value corresponds to enum AVPixelFormat audio: the sample format, value corresponds to enum AVSampleFormat

◆ frame_rate

AVRational AVBufferSrcParameters::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 AVBufferSrcParameters::height

◆ hw_frames_ctx

AVBufferRef* AVBufferSrcParameters::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 AVBufferSrcParameters::sample_aspect_ratio

Video only, the sample (pixel) aspect ratio.

◆ sample_rate

int AVBufferSrcParameters::sample_rate

Audio only, the audio sampling rate in samples per secon.

◆ time_base

AVRational AVBufferSrcParameters::time_base

The timebase to be used for the timestamps on the input frames.

◆ width

int AVBufferSrcParameters::width

Video only, the display dimensions of the input frames.
