The iFrameWidth/iFrameHeight fields are already aligned by the
SetActualPicResolution() function. Previously when iFrameWidth was
aligned directly in ParamBaseTranscode, this aligned value was used
to set iActualWidth/iActualHeight - losing the original, cropped
size.
This makes sure the output bitstream from the test of encoding
res/Static_152_100.yuv actually is cropped as it should.
Previously the loop filter was unconditionally enabled
regardless of what encoder parameter was set. If using
SEncParamBase instead, the loop filter was always disabled.
Previously, these fields kept whatever value was set by
FillDefault. The corresponding fields were set properly within
sSpatialLayers, but the fields within the main struct were left
with the default values.
This doesn't change the hashes in the unit test, since these
fields don't seem to be used in the produced bitstream at all.
TRUE/FALSE has intentionally been left in use for the few
platform specific APIs that define these constants themselves
and expect them to be used, for consistency.
