  8 avril 2023, par vl4d

  i am using ffmpeg to encode mp4 files to hls for streaming with this script

  


  for file in *.mp4; do ffmpeg -i "$file" -vbsf h264_mp4toannexb -g 48 -sc_threshold 0 \
    -map 0:0 -map 0:1 -map 0:0 -map 0:1 -map 0:0 -map 0:1 \
    -s:v:0 640x360 -crf:v:0 16 \
    -s:v:1 1280x720 -crf:v:1 20 \
    -s:v:2 1920x1080 -c:v:2 copy -c:a copy \
    -var_stream_map "v:0,a:0,name:360p v:1,a:1,name:720p v:2,a:2,name:1080p" \
    -preset fast -hls_allow_cache 1 -threads 0 -f hls -hls_playlist_type vod -keyint_min 48 -hls_time 3 \
    -hls_flags independent_segments -master_pl_name "${file%.mp4}".m3u8 \
    -hls_segment_filename ./"${file%.mp4}"-%v/segment_%03d.ts ./"${file%.mp4}"-%v/play.m3u8 ; done

• Creating a .m3u8 file for .ts files that already exist

  25 octobre 2019, par user12267838

  I need to create an m3u8 file - either from scratch or with a program - for existing .ts files that I have.

  I have 10 .ts files, all are the same duration, same fps, etc..

  I tried generating an m3u8, but the VLC Player shows a corrupted file every time I play it. The duration is incorrect, the video freezes at some parts while other parts play choppy and even lose all quality.

  I tried using FFmpeg to create a .m3u8 file for another mp4 that does not have the same content as the .ts files, but should be the same fps and the same duration of all .ts files combined.

  Here is the command which failed me :

  `ffmpeg -i background.mp4 -g 50 -hls_time 2 output.m3u8`

  ---

  I tried creating a m3u8 file from scratch,

  like this :

  #EXTM3U
  
  #EXT-X-VERSION:3
  
  #EXT-X-TARGETDURATION:4
  
  #EXT-X-MEDIA-SEQUENCE:5
  
  #EXTINF:2.000000,
  
  export-1080p--0.ts
  
  #EXTINF:2.000000,
  
  export-1080p--1.ts
  
  #EXTINF:2.000000,
  
  export-1080p--2.ts
  
  #EXTINF:2.000000,
  
  export-1080p--3.ts
  
  #EXTINF:2.000000,
  
  export-1080p--4.ts
  
  #EXTINF:2.000000,
  
  export-1080p--5.ts
  
  #EXTINF:2.000000,
  
  export-1080p--6.ts
  
  #EXTINF:1.000000,
  
  export-1080p--7.ts
  
  #EXT-X-ENDLIST

  But that failed as well.

  With ffmeg command :

  ffmpeg -i [filename.ts]

  I have checked all of my .ts files, they are all 00:00:02.02

  ---

  In this thread I have found a command, I need a similar command that allows me to use an input of multiple .ts files.

  ffmpeg -i input.ts \
   map 0 -c copy \
   f segment -segment_list out.m3u8 \
   segment_time 60 \
  out%03d.ts

  ---

  Is there a way to :

  a) create a m3u8 by hand ?

  b) use a program to create a m3u8 ?

  c) use ffmpeg to fetch the .ts files so that it makes a playable m3u8 file ?

  Does anyone know how I can get it done ?

• Concatinating mp4 files to a single mp4 file [migrated]

  20 juin 2013, par Vipin Nair

  I have some mp4 video files with me and i need to concatenate them one by one and make a single MP4 video file.

  I came to know about FFMPEG through which we can concat files.

  I tried doing

  ffmpeg -i concat:'file1.mp4|file2.mp4' -vcodec copy -acodec copy  -y OutCome.mp4

  But while executing the command i always get file2.mp4,no such file exists,but the file is there in the folder.

  What i am doing wrong ? or is there any other tool which can help me achieve this target through command line.
