• 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 ?

• How to merge two videos in android

  4 juillet 2016, par Lukas

  I’m new to android, but not new to mobile development.

  My goal is to record two videos, and the mix it into one video using audio from both tracks. E.g two recorded videos are both 10 seconds. I want to take the first 5 seconds from the first video, and the last 5 seconds from the second video, combine them together with combined audio from both videos, and have it in an mp4 file.

  On iOS there is an AVFoundation framework, which lets you combine multiple videos and audio into one video file (h.264 codec in mp4 container). I want to achieve similar results on android, but fail miserably at finding frameworks or 3rd party libs for doing that. If anyone could help me by showing some links or any directions where to look for information it would be really helpful. Thanks in advance !
