centos7安裝視頻標註工具vatic

https://www.zhihu.com/video/921676593573801984

前言：若你跟著官方cvondrick/vatic 文檔做的話一定會痛不欲生踩坑無數。。。不要問我怎麼知道的，希望此篇可以幫助和我一樣正在踩坑的小夥伴們。

centos是現成的，先裝docker

yum -y install dockeryum makecache fast

配置一下阿里鏡像加速器（需要登錄阿里賬號查看地址替換掉XXXXX）

vim /etc/docker/daemon.json{ "registry-mirrors": ["XXXXXXX"]}sudo systemctl daemon-reloadsudo systemctl restart dockersystemctl enable docker

ok，下面安裝vatic

docker pull jldowns/vatic-docker

裝好後啟動

docker run -t -i -P jldowns/vatic-docker /bin/bashcd /root/vatic./startup.shturkic status --verify

複製一個SSH隧道

docker ps -l

會看到埠映射的地址，我的是32771

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESe3786c618f69 jldowns/vatic-docker "/bin/bash" 41 seconds ago Up 38 seconds 0.0.0.0:32771->80/tcp, 0.0.0.0:32770->443/tcp desperate_newton

然後去瀏覽器輸入地址就可以看到頁面了。。。。

啟動docker時用

docker run -t -i -P -v /home/ffmpeg-project:/root/vatic/ffmpeg-project --privileged=true jldowns/vatic-docker /bin/bash

可以把本地/home/ffmpeg-project目錄映射到docker的/root/vatic/ffmpeg-project目錄

在centos /home/ffmpeg-project目錄下放入一些視頻，並創建directory目錄，若你已經安裝ffmpeg，可以寫一個小腳本批量轉換視頻【在宿主機轉碼可以獲得更好的性能】

vi convert_mp4_to_jpg.sh#!/bin/bash#Program:# convert MP4 to jpg#History:#2017/12/02 raulxty@163.com First releasePATH=/root/anaconda3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/binexport PATHfilelist=$(find *.mp4)OLDIFS="$IFS"IFS=$"
"for filename in *.mp4#$(find -iname *.mp4)do mkdir "ffout-${filename%.*}" ffmpeg -i $filename /home/ffmpeg-project/"ffout-${filename%.*}"/%03d.jpgdoneIFS=$OLDIFS

很快就把所有視頻變成圖片幀啦！

將視頻格式化為vatic可以理解的格式：

turkic formatframes ffmpeg-project/ffout-*/ ffmpeg-project/directory

導入視頻：

turkic load aaa ffmpeg-project/directory/ Car Person Bicycle Fence IndicatorLight indicator LaneLine Tricycle zebraCrossing --offline

aaa是識別碼，ffmpeg-project/directory/是圖片幀目錄，後面的Car，Person等是標籤，--offline 表示不發布亞馬遜Mturk

發布命令：

turkic publish --offline

刪除視頻

turkic delete aaa --force
