• Download M3U8 That Is Playable

  15 octobre 2022, par Devin Dixon

  I am trying to download a livestream from this traffic camera source : https://vss1live.dot.ga.gov/lo/alph-cam-002.stream/playlist.m3u8

  


  The ffmpeg I am using is :

  


  ffmpeg -i https://vss1live.dot.ga.gov/lo/alph-cam-002.stream/playlist.m3u8 -preset slow -codec:a libfdk_aac -b:a 128k -codec:v libx264 -pix_fmt yuv420p -b:v 4500k -minrate 4500k -maxrate 9000k -bufsize 9000k -vf scale=-1:720 test.mp4


  


  And here are the logs when I quit the recording :

  Except the video doesn't seem to be playable by VLC or Quicktime. Given that the stream can end at any moment thus ending the file, how do I make the file actually playable ?

  


• how to download sample-aes m3u8 with ffmpeg ? [hls prompts : Unable to open key file skd:xxxxxxx]

  18 octobre 2024, par Mam Ghagh

  I am newbie in programming and need help.
  
Story and Question -> I have a m3u8 manifest like :

  


  #EXTM3U
#EXT-X-VERSION:5
#EXT-X-TARGETDURATION:7
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-KEY:METHOD=SAMPLE-AES,URI="skd://xxxxxx",IV=yyyyyyy,KEYFORMAT="com.apple.streamingkeydelivery",KEYFORMATVERSIONS="1"
#EXTINF:6,
https://someurl.com/index_1_0.ts
#EXTINF:6,
https://someurl.com/index_2_0.ts
...


  


  which is available on https://someurl.com/my.m3u8
  
So, When I executed ffmpeg command
  
ffmpeg -i "https://someurl.com/my.m3u8" -c copy out.mp4
  
the following message appeared
  
[hls @ 000002de75f89bc0] Unable to open key file skd://xxxxxx
  
Now the question is, How should I address the key ? Should I save the key into a file and address it in the m3u8 manifest ? or any other answer ?

  


• Any alternative of Ffmpeg for Youtube live streaming app ?

  26 avril 2017, par samir.k433

  In this youtube live streaming app they are using Ffmpeg for encoding audio and video, and then for streaming to server. It’s somehow complex for me (specifically the build tasks).
  Is there any alternative instead of using Ffmpeg in this regard ?
