• How do I know if an M3U8 link is from a live transmission or a complete file ?

  17 août 2022, par karurosagu

  This is my problem

  


  I have a downloader app, and one of it's features is downloading M3U8 links using FFmpeg under the hood

  
It only supports a selection of sites and platforms, but i don't want to add support for unknown origin links, not just because it's obviously missing the right headers, cookies and user agent and the user would have to put all of that to work, the main reason is that I don't know how to determine if that link leads to a complete file or if it leads to a live transmission


  This is what happened :

  


  A user of my app gave me a link to test it manually, i ran the code and I noteiced it was taking a lot of time to finish having a decent speed, the file was getting too big, and when i ask him where did the link came from he said it was from a Live TV stream : I had to cancel the download

  


  So, how do i know in FFmpeg if a given M3U8 link leads to a complete file rather than a live transmission ?

  


• rtp live stream with libvlc

  20 mai 2011, par sokrat3s

  I would like to use libvlc api to stream live data but instead of file I would like to stream from a data pointer (nal units from x264 encoding).

  Is there a way to do this ? Is it already implemented ?

  Thank you in advance.

• How can I start a live stream fixing stdout of ffmpeg prob ?

  8 janvier 2019, par Antonin Rouard

  It is my first time here. Be kind with me ^^ trying to do my best.
  I want to stream a 24/7 live opn Toutube with live-stream-radio ; everything goes well when I start until FFMPEG find an error at code 1 with stdout, probably a problem with the codec or the version of FFMPEG (bad compilation ?).

  How can I fix this to start a stream ? :) thx

  Tried to do a stream with OBS, but it is too complicated on my Raspbian (Raspberry Pi 3B+). I compiled many versions of FFMPEG and I don’t know how to fix this.

  live-stream-radio —start (file directory)

  /////

  ffmpeg stdout :

  ffmpeg err :

  Error : ffmpeg exited with code 1 : Error initializing complex filters.
  Invalid argument
