• ffmpeg incorrect duration when converting video to HLS

  12 octobre 2016, par Julie Bsd

  I’m facing an issue using ffmpeg to convert video, precisely mp4 video => Http Live Streaming (HLS)

  Once converted to HLS, the .m3u8 file has a wrong duration (e.g : 20,1s instead of 20.00s), causing bugs when playing it with AVPlayer on iOS.
  Playing the video with Safari cause the same issue.

  Example :
  1) Open Safari
  2) Play this video that i’ve converted
  3) Look at the download progression, stopped at 98% cause of wrong duration.
  
  4) When you slide between 98% and 100%, the video player can crash.

  EDIT 1 :

  I’ve edited the command line

   ffmpeg -i  video.mp4 \
  
   -codec copy \
  
   -acodec copy \
  
   -map 0 -f ssegment -g 60 -sc_threshold 0 \

• random .ts filenames in the m3u8 file

  14 octobre 2016, par Arya Same

  Hi guys my ffmpeg line currently looks like this

  ffmpeg -i "http://x.com/x.ts" -s 810x520 -pix_fmt yuv420p -vcodec copy -acodec copy -bsf:v h264_mp4toannexb -preset baseline  -strict -2 -flags -global_header -f segment -segment_list "E:\2.m3u8"  -segment_time 10 -segment_list_size 5 "E:\2-%%3d.ts"

  it generates .ts files like 1.ts 2.ts etc..

  but if you are gonna to look to twitch.tv’s m3u8 file it looks like this
