@ AV_PRIMARY_EYE_RIGHT
Right eye.
it s the only field you need to keep assuming you have a context There is some magic you don t need to care about around this just let it vf default minimum maximum flags name is the option name
@ AV_STEREO3D_VIEW_LEFT
Frame contains only the left view.
@ AV_STEREO3D_SIDEBYSIDE_QUINCUNX
Views are next to each other, but when upscaling apply a checkerboard pattern.
int av_stereo3d_view_from_name(const char *name)
Get the AVStereo3DView form a human-readable name.
This structure describes decoded (raw) audio or video data.
uint32_t baseline
The distance between the centres of the lenses of the camera system, in micrometers.
@ AV_STEREO3D_VIEW_RIGHT
Frame contains only the right view.
@ AV_STEREO3D_VIEW_UNSPEC
Content is unspecified.
@ AV_STEREO3D_UNSPEC
Video is stereoscopic but the packing is unspecified.
AVRational horizontal_field_of_view
Horizontal field of view, in degrees.
@ AV_STEREO3D_SIDEBYSIDE
Views are next to each other.
@ AV_STEREO3D_VIEW_PACKED
Frame contains two packed views.
@ AV_STEREO3D_2D
Video is not stereoscopic (and metadata has to be there).

const char * av_stereo3d_view_name(unsigned int view)
Provide a human-readable name of a given stereo3d view.
@ AV_STEREO3D_FRAMESEQUENCE
Views are alternated temporally.
@ AV_STEREO3D_LINES
Views are packed per line, as if interlaced.
int av_stereo3d_primary_eye_from_name(const char *name)
Get the AVStereo3DPrimaryEye form a human-readable name.
int flags
Additional information about the frame packing.
Rational number (pair of numerator and denominator).
@ AV_PRIMARY_EYE_LEFT
Left eye.
AVRational horizontal_disparity_adjustment
Relative shift of the left and right images, which changes the zero parallax plane.
AVStereo3D * av_stereo3d_alloc_size(size_t *size)
Allocate an AVStereo3D structure and set its fields to default values.
enum AVStereo3DPrimaryEye primary_eye

AVStereo3D * av_stereo3d_alloc(void)
Allocate an AVStereo3D structure and set its fields to default values.
these buffered frames must be flushed immediately if a new input produces new the filter must not call request_frame to get more It must just process the frame or queue it The task of requesting more frames is left to the filter s request_frame method or the application If a filter has several the filter must be ready for frames arriving randomly on any input any filter with several inputs will most likely require some kind of queuing mechanism It is perfectly acceptable to have a limited queue and to drop frames when the inputs are too unbalanced request_frame For filters that do not use the this method is called when a frame is wanted on an output For a it should directly call filter_frame on the corresponding output For a if there are queued frames already one of these frames should be pushed If the filter should request a frame on one of its repeatedly until at least one frame has been pushed Return or at least make progress towards producing a frame
