Question

我已经安装了Nginx Plus并为流媒体配置了HLS。在请求m3u8文件时，我收到错误：

2015/09/29 13:32:34 [error] 5814#5814: *1 open() "/usr/video/hls/CODECS="avc1.42e00a,mp4a.40.2"" failed (2: No such file or directory)

m3u8文件包含以下内容：

#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=545600,RESOLUTION=416x234,CODECS="avc1.42e00a,mp4a.40.2"
/usr/video/hls/myvideo_low.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1755600,RESOLUTION=640x360,CODECS="avc1.42e00a,mp4a.40.2"
/usr/video/hls/myvideo_high.m3u8

Nginx配置是：

location /hls {
      root   /usr/video;
      hls;
      hls_fragment            5s;
      hls_buffers             10 10m;
      hls_mp4_buffer_size     1m;
      hls_mp4_max_buffer_size 5m;
      types {
           application/vnd.apple.mpegurl m3u8;
           video/mp2t ts;
      }
      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Cache-Control' 'no-cache';
}

在浏览器中，我收到警告：＆＃34;未发现TS片段＆＃34;。

Answer 1

为了从ts这样的静态文件动态创建mp4段，文件名和扩展名必须出现在m3u8播放列表文件名中：

myvideo_high.mp4.m3u8

的

myvideo_high.mp4

有关：

myvideo_high.m3u8

它假设细分已经存在。

Serving Media with NGINX Plus白皮书显示了手动创建的m3u8变体播放列表的示例，由于页面格式化（换行），不正确：

#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=545600,RESOLUTION=416x234,
CODECS="avc1.42e00a,mp4a.40.2"
/hls/myvideo_low.mp4.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1755600,RESOLUTION=640x360,
CODECS="avc1.42e00a,mp4a.40.2"
/hls/myvideo_high.mp4.m3u8

#EXT-X-STREAM-INF信息应该在一行上（没有换行符）：

 #EXTM3U
 #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=545600,RESOLUTION=416x234,CODECS="avc1.42e00a,mp4a.40.2"
 /hls/myvideo_low.mp4.m3u8
 #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1755600,RESOLUTION=640x360,CODECS="avc1.42e00a,mp4a.40.2"
 /hls/myvideo_high.mp4.m3u8

Nginx Plus不流式传输HLS
