The Fire Escape is a 4K benchmark that measure the time it takes to encode a 4K file to x264 using open souce video editor OpenShot

uses a shotcut project file with a raw 4k video file, flac music by GUNSHIP, Text Overlay

above scores are average of 5 runs
please note that these systems are not benchmark systems and are real world

  • bench.x264.py Encoding 3840x2160p24 4K Shotcut Project using qmelt to x264 with Slow Preset and 16 CRF
  • bench.x265.py Encoding 3840x2160p24 4K Shotcut Project using qmelt to x265 with Slow Preset and 16 CRF
  • bench.vp9.py whenever google gets around to implementing proper multi-threading
  • bench.av1.py whenever aomedia gets around to finalizing spec and implementing multi-threading

Install

Tests cpu/ram and ssd/hdd and the results are in seconds

Beam

AMD ReLive

  • Crimson Settings > ReLive > Streaming > Custom Stream
  • Server URL: Paste Closest Ingest here
  • Connection Key: Paste Stream Key here
  • Streaming Profile High (720p60 @ 3.5Mbps)

Notes:

  • test stream record https://beam.pro/nwgat?vod=655012 (source mp4)
  • The quality varies by scenes/games
  • AMD seems to be doing CABAC coding which is nice
  • ~I dont know if 2-Pass is enabled yet yep they are doing 2-Pass
  • no HEVC streaming (yet) even with a custom server
  • rant: why the heck do stream sites only do 3.5Mbps? its annoying

Created this simple encoder script while trying out daala

Features:

  • Select file
  • Number of frames to skip
  • Number of frames to encode
  • Uncompressed y4m output file
  • Lossless png file from daala encode (uses y4m file from dump_video)
  • Lossless png file from source
  • Linux Bash Version
  • and by unpopular demand a Batch Version for Windows

Requirments

  • encoder expects y4m, so you need to ffmpeg -pix_fmt yuv420p -i any-source-video.webm output.y4m
  • ffmpeg needed for png frame extracting

Install Linux

cd daala/examples/

wget https://raw.githubusercontent.com/nwgat/scripts/master/nwgatdaalaenc.sh

chmod +x nwgatdaalaenc.sh

./nwgatdaalaenc.sh

Install windows

Download https://raw.githubusercontent.com/nwgat/scripts/master/nwgatdaalaenc-win.bat

copy to daala folder

Run it

notes:

  • Need to figure out why echo says its off on windows
  • Inputing nothing into frames/encodeframes on windows fails, need to figure that out
  • Perhaps more options to say yes or no, but this works for me

(almost) up to date daala builds for windows
64-bit for now, if anyone need 32-bit just contact me

Compiler Details(for nwgat builds)

  • Cygwin64 1.7.32(0.274/5/3) or later
  • libogg 1.3.1-1 or later

Usage

Source: ffmpeg -pix_fmt yuv420p -i any-source-video.webm source.y4m
Source: (720p resize) ffmpeg -pix_fmt yuv420p scale=1280:-1 -i any-source-video.webm source.y4m
Encoding: encoder_example -v 20 source.y4m -o daala-video.ogv
Decoding: dump_video daala-video.ogv -o daala-video.y4m
Playback: Play daala-video.y4m in MPC-BE

Use between 0-55 (0 being lossless), daala supports upto 511 but thats pointless in my testing

Issues

Only use same build for the encoded file.
daala is not finished. so file decoding will break between builds

Download

  1. Install Cygwin x64 with wget
    https://cygwin.com/setup-x86_64.exe

  2. Install apt-cyg
    wget rawgit.com/XadillaX/apt-cyg/master/apt-cyg

    install apt-cyg /bin

  3. Install Packages
    apt-cyg install gcc-core make pkg-config autoconf automake libtool libogg-devel libpng-devel libjpeg-devel check git

  4. Compile Daala

    git clone https://git.xiph.org/daala.git

    cd daala

    ./autogen.sh

    ./configure --disable-player

    make -j22

    make tools

if the compile fail try commenting out
CFLAGS="-std=c89 -pedantic -Wall -Wextra -Wno-parentheses -Wno-long-long -Wno-overlength-strings $CFLAGS"

CC_CHECK_CFLAGS_APPEND([-U__STRICT_ANSI__])

with # on front of the lines
from configure.ac file

issues: only encoder works for me atm, i need to figure out howto properly compile SDL, tools might fail to compile too with make tools
