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

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.

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.
