• How to make HLS start from the begining

  15 juillet 2016, par Ariel Argañaraz

  I need some help with HLS streaming, I’m trying to create a playlist for streaming,

  I’m using ffmpeg to generate the files and the .m3u8 files. And for playing i’m using a web page with videojs player

  The idea is to simulate a live streaming using files already created.

  The problem is that in some version of iphone works and in another does not work.
  The problem is that when I start play the video in the Safari browser of my phone it freezes for a while and then download and play the last segment.

  for example if the video is split in 4 differents .ts files.
  It starts playing from the 4th .ts file and then stop.

  The problem is that I have 2 iphone mobile phone, one of them works perfectly but the other one not

  The not working cell phone is a iphone 6 (version 9.2.1)

  Here is my m3u8 file. Note that I’m using the #EXT-X-PLAYLIST-TYPE:EVENT and I remove the #EXT-X-ENDLIST from the botton. So it should be played as an live streaming.

  It works for another phones, it begins from the 0 second when I set the #EXT-X-START:TIME-OFFSET=0

  but in this version (9.2.1) the video freezes and then jumps to the last segment (webinar-3.ts) plays that segment and finally stop.

  #EXTM3U
  
  #EXT-X-VERSION:4
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXT-X-ALLOW-CACHE:NO
  
  #EXT-X-PLAYLIST-TYPE:EVENT
  
  #EXT-X-START:TIME-OFFSET=0
  
  #EXT-X-TARGETDURATION:6
  
  #EXTINF:5.046444,
  
  webinar-0.ts
  
  #EXTINF:5,
  
  webinar-1.ts
  
  #EXTINF:5,
  
  webinar-2.ts
  
  #EXTINF:5,
  
  webinar-3.ts

  Have anybody got an idea of what i’m doing wrong or how to get a m3u8 config that works for this iphone version ?

• ffmpeg : Need to convert source video to web/phone html5 players. Willing to pay [on hold]

  25 juillet 2015, par mariotanenbaum

  I need somebody to write me commands for converting videos and i’m willing to pay that.

  I need to convert most of these : (if ffmpeg doesn’t support any of those, just ignore it)

  mov (QuickTime Movie)
  mp4 (MPEG-4 Video)
  mpe (MPEG Video)
  mpeg (MPEG Video)
  mpeg4 (MPEG-4 Video)
  3g2 (Mobile Video)
  3gp (Mobile Video)
  3gpp (Mobile Video)
  asf (Windows Media Video)
  avi (AVI Video)

  To most of these :

  HTML5, Flash : MP4/H.264, High profile
  HTML5 : WebM
  HTML5 : Ogg
  Mobile : MP4/H.264, Baseline profile, 480x360, for wide compatibility
  Mobile : MP4/H.264, Main profile, 1280x720, for newer iOS devices (iPhone 4, iPad, Apple TV)
  Mobile : 3GP/MPEG4, 320x240 and/or 177x144, for non-smartphones*

  Nothing which would not work out of box in ffmpeg
  Some tweaking about processor usage and quality is ok but not so important.

  Goal is to get suitable clips for playing in chrome, firefox, ie9, iphone and android.
  For now iphone is the most important.

  IF you have some spare time, feel free to contact me, i would pay somebody just to send me "commands". It doesn’t to be anything "smart" just so that i don’t need to spend so much time trying learn all about ffmpeg.
