• 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 RTSP stream with size=N/A bitrate=N/A [closed]

  6 octobre 2024, par Comycos

  When I try to stream a video it seems to work but bitrate and size are N/A frame=  277 fps= 26 q=-1.0 size=N/A time=00:00:11.07 bitrate=N/A speed=1.05x

  


  I run the following command to stream a video to a RTSP server :
ffmpeg -re -stream_loop -1 -i idurre-2024-09-17-12h33m19s.mp4 -c copy -f rtsp -rtsp_transport tcp rtsp://localhost:8554/test

  


  The output ffmpeg is like this :

  The server I'm streaming to is a MediaMTX which is supposed to receive the stream. It seems to be connected as it logs it :
