使用nginx-vod-module hls &&dash &&Thumbnail 处理

 

备注：
以前写过使用ffmpeg 转换为m3u8进行hls 视频处理，实际上有一个开源的很强大的工具，我们基本不用什么代码就可以实现hls、
dash、Thumbnail ，很强大

安装

• 使用源码编译

参考 https://github.com/kaltura/nginx-vod-module

./configure --add-module=/path/to/nginx-vod-module
make
make install

• 使用容器

已经有别人做好的镜像了

docker pull nytimes/nginx-vod-module

基本使用

我直接clone 别人的参考代码

docker run -p 3030:80 -v $PWD/videos:/opt/static/videos -v $PWD/nginx.conf:/usr/local/nginx/conf/nginx.conf nytimes/nginx-vod-module

访问

HLS: http://localhost:3030/hls/devito,360p.mp4,480p.mp4,720p.mp4,.en_US.vtt,.urlset/master.m3u8
Dash: http://localhost:3030/dash/devito,360p.mp4,480p.mp4,720p.mp4,.en_US.vtt,.urlset/manifest.mpd
Thumbnail: http://localhost:3030/thumb/devito360p.mp4/thumb-1000.jpg

配置说明

nginx config

   hls  dash   thumb
        location /hls/ {
            vod hls;
            alias /opt/static/videos/;
            add_header Access-Control-Allow-Headers '*';
            add_header Access-Control-Allow-Origin '*';
            add_header Access-Control-Allow-Methods 'GET, HEAD, OPTIONS';
        }

        location /thumb/ {
            vod thumb;

            add_header Access-Control-Allow-Headers '*';
            add_header Access-Control-Allow-Origin '*';
            add_header Access-Control-Allow-Methods 'GET, HEAD, OPTIONS';
        }

        location /dash/ {
            vod dash;
            alias /opt/static/videos/;
            add_header Access-Control-Allow-Headers '*';
            add_header Access-Control-Allow-Origin '*';
            add_header Access-Control-Allow-Methods 'GET, HEAD, OPTIONS';
