Description

Attached file decodes fine with libvpx-vp9 decoder wrapper (Or anything using libvpx, like Chromium based browsers), but random noise after the first frame with ffvp9.

It was created with the following command, using libvpx-vp9 encoder wrapper and libvpx 1.3.0.

./ffmpeg -t 5 -i test-720p.mpg -c:v libvpx-vp9 -cpu-used 1 -crf 10 -b:v 0 -an -lag-in-frames 16 -frame-parallel 1 test_vp9.webm

The video decodes fine with ffvp9 is i use 2pass mode instead of 1pass to create it.

./ffmpeg -t 5 -i test-720p.mpg -c:v libvpx-vp9 -cpu-used 1 -crf 10 -b:v 0 -an -lag-in-frames 16 -frame-parallel 1 -pass 1 -f webm /dev/null && \
./ffmpeg -t 5 -i test-720p.mpg -c:v libvpx-vp9 -cpu-used 1 -crf 10 -b:v 0 -an -lag-in-frames 16 -frame-parallel 1 -pass 2 test_vp9.webm
