• Manipulating one video into multi outputs with FFmpeg results in no audio in the last output

  27 octobre 2015, par my name is

  Using FFmpeg, I’m trying to do some filtering operations on one input video to scale it (out1), scale and trim it (out2).
  This is the command I’m using :

  ffmpeg -y \
  
  -i "Robotica_1080.mkv" \
  
  -filter_complex "[0:v]split=2[v1][v2]; \
  
  [v1]scale=640:360,setpts=PTS-STARTPTS[vout1]; \
  
  [v2]trim=10:15,scale=640:360,setpts=PTS-STARTPTS[vout2]; \
  
  [0:a]asplit=2[a1][a2]; \
  
  [a1]anull,asetpts=PTS-STARTPTS[aout1]; \
  
  [a2]atrim=10:15,asetpts=PTS-STARTPTS[aout2]; \
  
  [vout1][aout1]concat=n=1:v=1:a=1[out1]; \
  
  [vout2][aout2]concat=n=1:v=1:a=1[out2]" \
  
  -map "[out1]" "1.mp4" \
  
  -map "[out2]" "2.mp4" 

  1.mp4 is ok while 2.mp4 lasts 5 seconds as expected but without audio at all (the QuickTime inspector doesn’t write the audio codec)

  I tried to remove the trim/atrim filters, so the filter_complex parameter looked like this :

  -filter_complex "[0:v]split=2[v1][v2]; \
  
  [v1]scale=640:360[vout1]; \
  
  [v2]scale=640:360[vout2]; \
  
  [0:a]asplit=2[a1][a2]; \
  
  [a1]anull[aout1]; \
  
  [a2]anull[aout2]; \
  
  [vout1][aout1]concat=n=1:v=1:a=1[out1]; \
  
  [vout2][aout2]concat=n=1:v=1:a=1[out2]" \

  but still no audio on 2.mp4

  Can anyone give me a hint ?

  —EDIT—
  This is the output from first ffmpeg command :

• python : can't open file 'F :\\Episode Split\\Episode' : [Errno 2] No such file or directory [closed]

  26 février 2024, par Rafa Segovia

  everyone !

  


  I'm trying to write a python script to split a video into parts based on a list of expressions from a docx file, comparing them to the dialogue on an srt file.
I think I have everything installed on my Windows 10 pc.
I keep getting this error.

  


  python : can't open file 'F :\Episode Split\Episode' : [Errno 2] No such file or directory

  


  It's like it detects a space somewhere and stops reading a path.
There's no file called "Episode" anywhere mentioned on the script.
Can you take a look at the script and pinpoint how I can fix this error ?

  


  Thank you

  I tried removing spaces in the paths by using hyphens among other things.

  


• look for a specific filetype in a directory in php and send it to a different directory after conversion

  12 juin 2019, par flash

  I have a directory in which there is a mp4 file (including other files as well) which I want to convert into mp3 and then send it to different directory. I have used the following command line command to covert into mp3 and its working perfectly fine.

  ffmpeg -i 36031P.mp4 -map 0:2 -ac 1 floor_english.mp3 

  mp4 file is inside in_folder. Using ffmpeg, I want to convert mp4 file into mp3 and send it to out_folder.

  <?php
  
  $dir    = 'in_folder';
  
  $files1 = scandir($dir);
  
  print_r($files1);    /* It lists all the files in a directory including mp4 file*/
  
  ?>

  print_r($files1) lists all the file in a directory including mp4file.

  Problem Statement :

  I am wondering what php code I need to write so that it looks for only mp4 file inside the directory and send it to different directory (let say out_folder) after converting into mp3.
