Field Data Type Input/
Output Description
forceFrame XDAS_Int32
Input Force the current (immediate) frame to be
encoded as a specific frame type. See
enumeration
IVIDEO_FrameType
for more
details
interFrameInter
val XDAS_Int32
Input Number of B frames between two reference
frames; that is, the number of B frames between
two P frames or I/P frames. DEFAULT(0).
For example, this field will be:
0 - To use maxInterFrameInterval.
1 - Zero B frames between two reference frames.
2 - One B frame between two reference frames.
3 - Two B frames between two reference frames.
and so on...
mvAccuracy XDAS_Int32
Input Pixel accuracy of the motion vector.
See
IVIDENC2_MotionVectorAccuracy
enumeration in Table 4-1 for details.
sampleAspectRat
ioHeight XDAS_Int32
Input Sample aspect ratio height. This will be
considered by encoder only when
IH264HPVENC_VUICodingParams::
aspectRatioIdc
is
IH264HPVENC_ASPECTRATIO_EXTENDED
sampleAspectRat
ioWidth XDAS_Int32
Input Sample aspect ratio width. This will be
considered by encoder only when
IH264HPVENC_VUICodingParams::
aspectRatioIdc
is
IH264HPVENC_ASPECTRATIO_EXTENDED
ignoreOutbufSiz
eFlag XDAS_Int32

application needs codec to expect the requested
size or not
Valid values are
