• ffmpeg video trim - no video only audio

  24 août 2019, par Patrick

  I’m looking for some hints from you.

  I try to trim mp4 videos (mostly 25fps - 720p) with python 3.7 and ffmpeg subcommand.

  Video cut is working fine, but on short videos, below 1 sec, the output.mp4 has no video in it. i tried to view this by VLC and other apps, but still no video in this file. (>1.5 sec its working well with the same input file)

  I have tried this cuts with different video quality, but still same issue.

  Thanks in advance !

  Patrick

  ffmpeg -i test.mp4 -ss 00:00:00.5 -to 00:00:00.9  -c copy test_cut.mp4

  Python code :

  import sys
  
  import subprocess as sp
  
  import os
  
  
  
  from moviepy.tools import subprocess_call
  
  from moviepy.config import get_setting
  
  
  
  #tried different methods and filters, but still same issue              
  
          cmd = [get_setting("FFMPEG_BINARY"), "-i", new_path_in, "-ss", "00:00:"+startSec, "-to", "00:00:"+endSec, "-c:v", "copy","-c:a","copy","-pix_fmt","yuv420p", new_path_out]
  
          subprocess_call(cmd)
  
  
  
          print("cut from "+startSec+" to "+endSec+" done")

• PHP - Get MP4 location from video URL or Video Embeded [on hold]

  I am trying to fetch FREE video anime from acefile

  I have this link for example : http://acefile.net/embed-r9e9vomk8oc8-650x360.html

  What I want to do is to fetch where the mp4 is located and embed it in one of my website pages.

  I have a Chrome plugin that is able to download MP4 videos just by looking at the source page.

  Is there a way to achieve the same with PHP or Python ? Remember I only need the video location not to download it.

  Thanks all
