Enumeration Type Documentation

Video frame skip features for video decoder.

Remarks:
This enumeration data type should not be used for storage, but rather only for its constant values.
This enumeration defines a base set of values. Algorithms which require proprietary enumeration values may define them - much like extended fields in base structures. These extended enums should be between XDM_CUSTOMENUMBASE and 0x7FFF.
See also:
XDM_CUSTOMENUMBASE
Enumerator:
IVIDEO_NO_SKIP 

Do not skip any frame types.

IVIDEO_SKIP_P 

Decode the P frame/skip frames internally, but do not copy the decoded output to the output buffers. This should be indicated by setting the output buffers to NULL.

Remarks:
For example, if a B frame is dependant on the previously decoded P frame, the B frame shall be decoded and displayed successfully. For this, the P frame needs to be decoded, but not copied to the output buffer.
IVIDEO_SKIP_B 

Skip B, BI frames. For B frames, the decoder will decode the frame bitstream, and return as soon as the frame type is decisively decoded. Internally, the algorithm will modify its state, so that subsequent decoding of other frames is possible.

IVIDEO_SKIP_I 

Skip intra coded frame.

IVIDEO_SKIP_IP 

Skip I and P frame/field(s).

IVIDEO_SKIP_IB 

Skip I and B frame/field(s).

IVIDEO_SKIP_PB 

Skip P and B frame/field(s).

IVIDEO_SKIP_IPB 

Skip I/P/B/BI frames.

IVIDEO_SKIP_IDR 

Skip IDR Frame.

IVIDEO_SKIP_NONREFERENCE 
Todo:
add documentation
IVIDEO_SKIP_DEFAULT 

Default settings.

Video frame types.

Remarks:
For the various IVIDEO_xy_FRAME values, this frame type is interlaced where both top and bottom fields are provided in a single frame. The first field is an "x" frame, the second field is "y" field.
This enumeration data type should not be used for storage, but rather only for its constant values.
This enumeration defines a base set of values. Algorithms which require proprietary enumeration values may define them - much like extended fields in base structures. These extended enums should be between XDM_CUSTOMENUMBASE and 0x7FFF.

Remarks:
This enumeration data type should not be used for storage, but rather only for its constant values.
This enumeration defines a base set of values. Algorithms which require proprietary enumeration values may define them - much like extended fields in base structures. These extended enums should be between XDM_CUSTOMENUMBASE and 0x7FFF.

Video output buffer status.

Remarks:
Ownership of the buffers, either by application or algorithm, is conveyed via these values.
This reflects the status of ALL output buffers. For example, if video decoded output is in 4:2:0 format, all the 3 output buffers' status is described by this value. Similarly, for 4:2:2 formatted buffers, this value describes the single buffer's status.
This enumeration data type should not be used for storage, but rather only for its constant values.
This enumeration defines a base set of values. Algorithms which require proprietary enumeration values may define them - much like extended fields in base structures. These extended enums should be between XDM_CUSTOMENUMBASE and 0x7FFF.

Remarks:
For example, if a bitstream is erroneous and partially decoded, a portion of the decoded image may be available for display. Another example is if the bitstream for a given frame decode may be decoded without error, but the previously decoded dependant frames weren't successfully decoded. This would result in an incorrectly decoded frame.
IVIDEO_FRAME_OUTPUTSKIP 

The video frame was skipped (i.e. not decoded).
