• FFMPEG HLS stream for Android and IOS

  30 juin, par Poda

  I'm trying to stream to mobile devices with ffmpeg and apache2.2 but I haven't been successful.

  



  I used this command to create the segments and the playlist :

  



  ffmpeg -i http://x.x.x.x:8080 -codec:v libx264 -r 25 -pix_fmt yuv420p -profile:v baseline -level 3 -b:v 500k -s 640x480 -codec:a aac -strict experimental -ac 2 -b:a 128k -movflags faststart -flags -global_header -map 0 -f hls  -hls_time 10 -hls_list_size 5 -hls_allow_cache 0 -sc_threshold 0 -hls_flags delete_segments -hls_segment_filename out%05d.ts list.m3u8


  



  The source is a http stream which is streamed by VLC media player.

  



  Example content of the list.m3u8 file :

  



  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-ALLOW-CACHE:NO
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:89
#EXTINF:10.000000,
out00089.ts
#EXTINF:10.000000,
out00090.ts
#EXTINF:10.000000,
out00091.ts
#EXTINF:10.000000,
out00092.ts
#EXTINF:9.000000,
out00093.ts
#EXT-X-ENDLIST


  



  I created another playlist file - playlist.m3u8 :

  



  #EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=512000
http://x.x.x.x/list.m3u8


  



  If I open this (playlist.m3u8) file in VLC media player then it plays.
It also works in desktop chrome and desktop firefox browsers with Video-js plugin flash fallback.

  



  I set the correct MIME types to the .ts and .m3u8 files in .htaccess file :

  



  AddType application/x-mpegURL .m3u8
AddType video/MP2T .ts


  



  FFprobe output for playlist.m3u8 :

  



  Input #0, hls,applehttp, from 'playlist.m3u8':
    Duration: N/A, start: 1.400000, bitrate: N/A
    Program 0
    Metadata: variant_bitrate : 512000

Metadata: variant_bitrate : 512000


  



  What should I do to make it work ?

  



  UPDATE

  



  It works if I provide a link to list.m3u8 file (created by ffmpeg).

  


• Duration of source video and subtracted audio are different

  22 avril 2018, par zpc

  The duration of source video and subtracted wav audio is different , why ?

  I’m recorgnizing subtitle from audio, and I need to add subtitle back to video. So I want the duration of audio and video the same.

  ffmpeg -i http://cdn.live.360.cn/huikan_news/vod-media/_XW_203286B417B7C6466B3B_20160627185953.m3u8 -vn test.wav -y

• Choose download resolution in m3u8 list with ffmpeg

  31 mars 2024, par Bruno Andrade

  I'm trying to download video from a m3u8 playlist using ffmpeg but I do not know how to choose the resolution to download. Currently the command is downloading the highest version

  



  the command I am using is :

  



  /home/user/bin/ffmpeg -user_agent "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0" -i "https://sitevideo.com/list.m3u8" -c copy "/home/file/video.ts"


  



  My list is this

  



  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=400000,NAME="low"
size1.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=800000,NAME="med"
size2.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=1900000,NAME="best"
size3.m3u8
