12 years agoFixed bugs in multi-layer code related to changing params
Adrian Grange [Fri, 13 Jan 2012 22:09:40 +0000 (14:09 -0800)]
Fixed bugs in multi-layer code related to changing params

When running multi-layer (ML) encodes and dynamically
changing coding parameters on the fly (e.g. frame
duration/rate, bandwidths allocated to each layer)
the encoder would not produce sensible output.

In certain cases the rate targeting would be
hideously inaccurate.

These fixes make it possible to change these coding
parameters correctly and to maintain accurate control
of the rate targeting.

I also added the specification of the input timebase
into the test program, vp8_scalable_patterns.c.

different reference frames, the only difference in calculating
these near_mvs is they may have different sign_bias, which

Multiple-resolution encoder

The example encoder down-samples the input video frames a number of
times with a down-sampling factor, and then encodes and outputs
bitstreams with different resolutions.

Support arbitrary down-sampling factor, and down-sampling factor
can be different for each encoding level.

For example, the encoder can be tested as follows.
1. Configure with multi-resolution encoding enabled:
../libvpx/configure --target=x86-linux-gcc --disable-codecs
--enable-vp8 --enable-runtime_cpu_detect --enable-debug
--disable-install-docs --enable-error-concealment
--enable-multi-res-encoding
2. Run make
3. Encode:
If input video is 1280x720, run:
./vp8_multi_resolution_encoder 1280 720 input.yuv 1.ivf 2.ivf 3.ivf 1
(output: 1.ivf(1280x720); 2.ivf(640x360); 3.ivf(320x180).
The last parameter is set to 1/0 to show/not show PSNR.)
4. Decode:
./simple_decoder 1.ivf 1.yuv
./simple_decoder 2.ivf 2.yuv
./simple_decoder 3.ivf 3.yuv
5. View video:
mplayer 1.yuv -demuxer rawvideo -rawvideo w=1280:h=720 -loop 0 -fps 30
mplayer 2.yuv -demuxer rawvideo -rawvideo w=640:h=360 -loop 0 -fps 30
mplayer 3.yuv -demuxer rawvideo -rawvideo w=320:h=180 -loop 0 -fps 30

The encoding parameters can be modified in vp8_multi_resolution_encoder.c,
for example, target bitrate, frame rate...

Modified API. John helped a lot with that. Thanks!
