• python ffmpeg "The system cannot find the file specified" [on hold]

  5 avril 2016, par k7zheng

  I’m pretty new to Python but I’ve been stuck on this for a while.

  Whenever I run :

  import subprocess, os
  
  os.ffmpeg = "/absolute/path/to/ffmpeg"
  
  subprocess.ffmpeg = "/absolute/path/to/ffmpeg"
  
  
  
  subprocess.call(['ffmpeg', '-i', 'C://Users//k7zheng//Desktop//A1//1.avi', '-r', '0.05', "newfiles//%02d.png"])

  I get the following :

  Traceback (most recent call last):
  
  File "C:/Users/k7zheng/Desktop/FT1.py", line 4, in <module>
  
  subprocess.call(['ffmpeg -i C:\\Users\k\Desktop\A1\1.avi -r 0.05 "newfiles\%02d.png"'])
  
  File "C:\Python34\lib\subprocess.py", line 537, in call with Popen(*popenargs, **kwargs) as p:
  
  File "C:\Python34\lib\subprocess.py", line 859, in __init__
  
  restore_signals, start_new_session)
  
  File "C:\Python34\lib\subprocess.py", line 1114, in _execute_child
  
  startupinfo)
  
  FileNotFoundError: [WinError 2] The system cannot find the file specified
  
  </module>

  Can you help me spot my issue ?
  I’ve tried :

  • changing slashes / to \ to double \ slashes
  • getting rid of the 2nd and 3rd lines
  • adding os.chdir(r"C :\software\ffmpeg\ffmpeg-20160330-git-be746e-win64-static\bin")
  • changing line 4 to subprocess.call(’ffmpeg -i c :\users\k7zheng\desktop\c1\1 -r -0.05 "newfiles\%02d.png"’, shell=True)

  I’m running Python 3.4.4

• ffmpeg command not working from bash script but working from command line [duplicate]

  6 octobre 2023, par SamTech

  I wrote a bash script that is generating command to encode video and create HLS playlist.

  


  Here is the script. To make it short and clear, i fill variables with hard-coded values.

  


  #!/bin/bash

# below variables are generated from some other script

basic="-hide_banner -y -i Sample.mp4 -profile:v main -crf 20 -sc_threshold 0 -g 50 -keyint_min 50 -hls_time 6"

renditions="-c:v:0 h264 -filter:v:0 scale=w=426:h=240:force_original_aspect_ratio=decrease -b:v:0 128k -maxrate:v:0 136k -bufsize:v:0 192k -c:v:1 h264 -filter:v:1 scale=w=640:h=360:force_original_aspect_ratio=decrease -b:v:1 256k -maxrate:v:1 273k -bufsize:v:1 384k -b:a 128k -c:a aac -ar 48000 -ac 2"

mapping="-map 0:v -map 0:v -map 0:a"
stream_map="-var_stream_map \"v:0,agroup:audio v:1,agroup:audio a:0,agroup:audio\""

hls="-hls_list_size 0 -f hls -hls_playlist_type vod -hls_segment_type mpegts -master_pl_name master.m3u8 -y %v_seg.m3u8"

# show final command
echo "Command:"
echo "ffmpeg ${basic} ${renditions} ${mapping} ${stream_map} ${hls}"

# execute command
ffmpeg ${basic} ${renditions} ${mapping} ${stream_map} ${hls}


  


  Here is complete output from the script, along with the error it is giving.
