修改

我的问题现在已经解决了（见下文），每个人都可以使用这个脚本下载m3u8流，如Apple的bipbop

ORIG问题

我创建了这个很好的脚本来下载Apple的BipBop示例HLS流。但是我没能玩它。如果您帮我解决了这个问题，我们都可以享受这个脚本：

#!/bin/bash
unset PROMPT_COMMAND
set -x
URL=https://devimages.apple.com.edgekey.net/streaming/examples/bipbop_16x9/bipbop_16x9_variant.m3u8
MANIFESTNAME=$(basename $URL)
LOCAL_MANIFEST=$MANIFESTNAME
URLPREF=$(dirname $URL)

wget $URL -O $LOCAL_MANIFEST

cat $LOCAL_MANIFEST | grep "#EXT-X-STREAM-INF:" -A1 | grep m3u8 > all_playlists.txt
cat $LOCAL_MANIFEST | grep "#EXT-X-MEDIA.*URI" | sed -e 's_.*URI=\"\(.*\)\".*_\1_' >> all_playlists.txt
#this will yield files which we already downloaded, but we want the index file itself
cat $LOCAL_MANIFEST | grep "#EXT-X-I-FRAME-STREAM-INF.*URI" | sed -e 's_.*URI=\"\(.*\)\".*_\1_' >> all_playlists.txt

while read playList; do
  FOLDER=$(dirname $playList)
  PL_NAME=$(basename $playList)
  LOCAL_PL=$FOLDER/$PL_NAME
  mkdir -p $FOLDER 2> /dev/null
  PL_URL=$URLPREF/$playList

  echo "PL_URL=$PL_URL"
  TSL=${FOLDER}_TSList.txt
  wget $PL_URL -O $LOCAL_PL 
  echo "LOCAL_PL=$LOCAL_PL"
  cat $LOCAL_PL | grep -v "^#" | uniq > $TSL
  echo "====== media list ======="
  cat $TSL
  echo "========================="
  #TS is actually any media file
  while read ts; do
    TS_NAME=$URLPREF/$FOLDER/$ts
    LOCAL_TS=$FOLDER/$ts
    echo $TS_NAME
    if [ -s $LOCAL_TS ]; then
      echo "Already exists. skiping."
    else
      wget $TS_NAME -O $LOCAL_TS
    fi
  done < $TSL
  rm $TSL
done < all_playlists.txt
rm all_playlists.txt
find . -name Thumbs.db -exec rm {} \;

当流准备就绪时，我使用Python的http服务器运行http服务器：

http-server -p 8090

然后尝试使用此命令播放：

open http://localhost:8090/bipbop_16x9_variant.m3u8 -a Safari

http服务器显示正常请求：

[12:24:51] "GET /bipbop_16x9_variant.m3u8" "Mozilla/5.0 (Macintosh..."
[12:24:51] "GET /gear1/prog_index.m3u8" "Mozilla/5.0 (Macintosh..."
[12:24:52] "GET /gear1/main.ts" "Mozilla/5.0 (Macintosh..."
[12:24:52] "GET /subtitles/eng_forced/prog_index.m3u8" "Mozilla/5.0 (Macintosh..."
[12:24:52] "GET /subtitles/eng_forced/fileSequence0.webvtt" "Mozilla/5.0 (Macintosh..."
[12:24:52] "GET /gear0/prog_index.m3u8" "Mozilla/5.0 (Macintosh..."
[12:24:52] "GET /gear0/main.aac" "Mozilla/5.0 (Macintosh..."
[12:24:52] "GET /subtitles/eng_forced/fileSequence1.webvtt" "Mozilla/5.0 (Macintosh..."

但Safari未能播放该流，显示＆＃34; 缺少插件＆＃34;消息...

任何想法请???我们需要这个流来进行iOS开发......

感谢@ libertyernie的评论，这个问题现在已经解决了。我自己实际上怀疑这个问题：Python的http服务器模块不是服务m3u8流的正确工具，因为它无法配置正确的内容类型。

更好的工具是Lighttpd。

<强>安装：

brew install lighttpd

现在创建一个配置文件 lighttpd.conf ：

server.document-root = "<full-path-no-~>/bipbop" 
server.port = 8090
mimetype.assign = (
  ".html" => "text/html", 
  ".txt" => "text/plain",
  ".jpg" => "image/jpeg",
  ".png" => "image/png",
  ".m3u8" => "application/vnd.apple.mpegurl",
  ".ts" => "video/MP2T"
)

最后两行对我们的成功至关重要。现在我们可以运行我们的流服务器：

lighttpd -D -f lighttpd.conf

现在我们可以打开http://localhost:8090/bipbop_16x9_variant.m3u8并观看视频流。
