For 1 pass CBR mode: increase waiting time after key frame
before we start sampling rate control behavior for determining
resize. This change need to disable one internal resize(DownUp)
temporally since it requires a longer clip to do so.

Reallocation of mi buffer fails if change size on the first frame and
change config in subsequent frames. Add a condition for resolution
check to avoid assertion failure.

Verify the dynamic resizer behavior for real time, 1 pass CBR mode.
Start at low target bitrate, raise the bitrate in the middle of the
clip, verify that scaling-up does occur after bitrate changed.

Verify the dynamic resizer behavior for real time, 1 pass CBR mode.
Run at low bitrate, with resize_allowed = 1, and verify that we get
one resize down event.

Adds an arbitrary-size resize library for use in scaling of input
frames in a non-normative manner in the vp9 encoder. The method
used is as follows:
Downsampling - Uses a 8 tap filter for factor of 2 decimation upto
a size just higher than the desired size. Then interpolates pixels
at a precision of 1/32 pel using a set of 8-tap filters.
Upsampling - Interpolates pixels at a precision of 1/32 pel using
a set of 8-tap filters.
There is no assembly optimization yet.

Modified the resize unit test so that it optionally
writes the encoded bitstream to file. The macro
WRITE_COMPRESSED_STREAM should be set to 1 to enable
output of the test bitstream; it is set to 0 by default.

Added the resize_test unit test to the VP9 set.
Set g_in_frames = 0 to avoid a problem when the total
number of frames being encoded is smaller than
g_in_frames. In this case the test will not have
access to the encoded frames and will not be able to
compare them for testing for encoder/decoder mismatch.

Improved coding performance made this test fail. Adjust the threshold
so that it passes again. A more stable metric is an open TODO.

Fixes a bug in vp9_set_internal_size() that prevented returning to
the unscaled state. Updated the ResizeInternalTest to scale both
down and up. Added a check that all frames are within 2.5% of the
quality of the initial keyframe.

This patch allows coding frames using references of different
resolution, in ZEROMV mode. For compound prediction, either
reference may be scaled.
To test, I use the resize_test and enable WRITE_RECON_BUFFER
in vp9_onyxd_if.c. It's also useful to apply this patch to
test/i420_video_source.h:
--- a/test/i420_video_source.h
+++ b/test/i420_video_source.h
@@ -93,6 +93,7 @@ class I420VideoSource : public VideoSource {
virtual void FillFrame() {
// Read a frame from input_file.
+ if (frame_ != 3)
if (fread(img_->img_data, raw_sz_, 1, input_file_) == 0) {
limit_ = frame_;
}
This forces the frame that the resolution changes on to be coded
with no motion, only scaling, and improves the quality of the
result.

Tests that the external interface to set the internal codec scaling
works as expected. Also updates the test to pull the height from
the decoded frame size rather than parsing the keyframe header,
in anticipation of allowing resolution changes on non-keyframes.

This commit starts to convert the tests to a system where the codec
to be used is provided by a factory object. Currently no tests are
instantiated for VP9 since they all fail for various reasons, but it
was verified that they're called and the correct codec is
instantiated.

Adds a test that ensures the application is able to trigger frame size
changes via vpx_codec_enc_config_set()
