• FFMPEG Combine multiple commands into one script

  16 février 2017, par ObeeWnn

  I need some help combining ffmpeg commands into a python or bash script :

  \Download
  
  Youtube-dl URL
  
  
  
  \Concatenate videos
  
  
  
  WD = "C:\"
  
  import glob
  
  files = glob.glob ('*.mp4')
  
  with open ('output.txt', 'w') as in_files:
  
      for eachfile in files: in_files.write('file \''+eachfile+'\'\n')
  
  
  
  ffmpeg -y -f concat -i output.txt -c copy input.mp4
  
  
  
  \Encode
  
  ffmpeg -y -threads 16 -i input.mp4 -c:a libfdk_aac -vbr 4 -c:v libx264 intermediate1.ts
  
  ffmpeg -y -threads 16 -i endscreen720.mp4 -c:a libfdk_aac -vbr 4 -c:v libx264 intermediate2.ts
  
  ffmpeg -y -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc tmp.mp4
  
  ffmpeg -y -i tmp.mp4 -itsoffset 00:00:20 -i lt1sub.avi -filter_complex overlay tmp1.mp4
  
  ffmpeg -y -i tmp1.mp4 -i intro.avi -filter_complex overlay tmp1a.mp4
  
  ffmpeg -y -i tmp1a.mp4 -i watermarkfile720.png -filter_complex "[0:v]drawtext=enable='between(n,30,116)' : 'fontfile=/Windows/Fonts/arial.ttf':text='TEXTGOESHERE':fontcolor=white:fontsize=50:x=150:y=(300)+th[text]; [text][1:v]overlay[filtered]" -map "[filtered]" -map 0:a -codec:v libx264 -codec:a copy tmp2.mp4
  
  ffmpeg -y -i tmp2.mp4 -r 60 -vf scale=1920:1080 output.mp4
  
  
  
  
  
  \Create Thumbnail
  
  ffmpeg -y -i tmp1.mp4 -vf drawtext="fontfile=/Windows/Fonts/arial.ttf': text='':fontcolor=white@1.0:fontsize=120:y=0:x=100" -ss 00:00:12 -vframes 1 out.png
  
  
  
  set /p input= Video #
  
  
  
  ffmpeg -y -i out.png  -i tnOverlay.png -filter_complex overlay,drawtext="fontfile=/Windows/Fonts/arial.ttf': text="%input%":fontcolor=white@1.0:fontsize=120:y=25:x=1190" out.png

  This is to download videos, place an intro video in the beginning, draw text over intro, concatenate the videos, apply watermark throughout video, apply outro, create thumbnail, etc.

• ffmpeg udp capture not working

  27 février 2017, par user3172852

  I have confirmed that there is incoming UDP packets at port 5968 of my computer with wireshark.
  However when I try to capture these packets with ffmpeg. After exiting (ctrl+c) I get no output, the output file is not even written to disk. This is what my terminal looks like.

• WebM live streaming via DASH

  4 juin 2018, par ewack

  I am following the instructions here to try to make WebM live streaming via DASH. My input is from an Axis camera and it is streaming as h264 encoding. I am using node to spin up the ffmpeg processes. I am able to create the .hdr file and the .chk files. The .mpd file is even created but it’s empty and I get an error saying :

  Could not write header for output file #0 (incorrect codec parameters ?): Operation not permittedStream mapping: Stream #0:0 -> #0:0 (copy)

  Here’s all of my code :

  var express = require('express');
  
  spawn = require('child_process').spawn;
  
  
  
  var app = express();
