• Inputing a List of Files for Concatenation with Node.js Module fluent-ffmpeg

  26 juin 2018, par carpiediem

  Version information

  • fluent-ffmpeg version : 2.1.2
  • ffmpeg version : 3.4.2
  • OS : Windows 10

  Code to reproduce

  ffmpeg('C:/path/to/list.txt').mergeToFile('C:/path/to/out.mp4', 'C:/path/to/temp');

  list.txt :

  file 'C:/path/to/chunk01.ts'
  
  file 'C:/path/to/chunk02.ts'
  
  file 'C:/path/to/chunk03.ts'
  
  file 'C:/path/to/chunk04.ts'

  Note : I’ve tried both absolute and relative paths, with the same result.

  Expected results

  A video file at C:/path/to/out.mp4 that matches the 4 files in list.txt, concatenated end-to-end.

  Observed results

  An empty file at C:/path/to/out.mp4 with 0 duration and only 15kB in size. No errors were thrown.

  This is the command that I’m trying to duplicate (it works as expected, with relative paths in list.txt) :

  C:/path/to> ffmpeg -f concat -i list.txt -c copy out.ts

  stdout & stderr

  stdout was empty. stderr is copied below (with file names modified to match the ones above) :

  11 juillet 2019, par albert

  I’m using PHP to run ffmpeg(4.0.2) render out MP4 file.
  MP4 file playable on all of iOS device, and most laptop, but not playable on android device.

  Here is the ffmpeg code I use to render the video

  /usr/local/bin/ffmpeg -filter_complex "[0]reverse[r];[0][r]concat, loop=1:65, setpts=N/15/TB" -r 15 -f image2 -i /Source/0001_CAM%02d.jpg -c:v libx264 -preset fast -crf 19 -profile:v baseline -movflags +faststart -pix_fmt yuv420p /Result/output.mp4

• FFMPEG - Convert MKV to MP4 with all streams (subtitles) and watermark

  24 juillet 2016, par ShinJii

  I spent few hours researching and still have problem...
  I want to convert .mkv file to .mp4 with watermark and subtitles (from mkv).

  I tried few commands but always error or success with watermark without subtitles.
  Here are some commands I tried (not all) :

  Partial Success - some files are converted with subtitles, but I have 153 files that are converted without subtitles... (both from .mkv to .mp4) :

  ffmpeg -i 025.mkv -vf "movie=logovideo2.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10,subtitles=025.mkv [out]" 25.mp4
  
  
  
  ffmpeg -i 001.mkv -i logovideo2.png -filter_complex "[0:v][1:v]overlay=0:0,subtitles=001.mkv[out]" -map "[out]" -map 0:a -c:s ass 001.mp4

  Fail - command with error :

  ffmpeg -i 001.mkv -i logovideo2.png -filter_complex "[0:v][1:v]overlay=0:0[out]" -map "[out]" -map 0:a -map 0:s -c:s ass 001.mp4
