This structure describes decoded (raw) audio or video data.
Memory handling functions.
Views are next to each other, but when upscaling apply a checkerboard pattern.
void * av_mallocz(size_t size)
Allocate a memory block with alignment suitable for all memory accesses (including vectors if availab...
Views are next to each other.
AVStereo3D * av_stereo3d_alloc(void)
Allocate an AVStereo3D structure and set its fields to default values.
Stereo 3D type: this structure describes how two videos are packed within a single video surface...
Structure to hold side data for an AVFrame.
const char * av_stereo3d_type_name(unsigned int type)
Provide a human-readable name of a given stereo3d type.
Video is not stereoscopic (and metadata has to be there).
Views are packed per line, as if interlaced.
AVStereo3D * av_stereo3d_create_side_data(AVFrame *frame)
Allocate a complete AVFrameSideData and add it to the frame.
Views are alternated temporally.
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
int av_stereo3d_from_name(const char *name)
Get the AVStereo3DType form a human-readable name.
#define FF_ARRAY_ELEMS(a)
Views are packed in a checkerboard-like structure per pixel.
Views are on top of each other.
AVFrameSideData * av_frame_new_side_data(AVFrame *frame, enum AVFrameSideDataType type, int size)
Add a new side data to a frame.
static const char *const stereo3d_type_names[]
common internal and external API header
Views are packed per column.
Stereoscopic 3d metadata.
