• How to start ffprobe with Windows PowerShell

  7 mars 2014, par sebastian

  I am using Zeranoes FFmpeg Builds for Windows and I can start the ff-prompt without installing anything. But how do I start ff-prompt.bat with Windows PowerShell ? I have tried a few things like Invoke-Expression or changing the $env:Path but nothing seems to work, because all I get is the message

  "C :\Users\Administrator>ECHO OFF

  bin\ffmpeg.exe could not be found."

  Is it even possible to start ff-prompt with PowerShell ? Every suggestion / solution is more than welcome.

  My goal is to have a solution that works like this here :
  http://spreadys.wordpress.com/2012/12/03/ffprobe-and-windows-powershell/

  but I want to do that automatically for all my clips, thats why I need to start ffprobe with powershell.

  Okay I tried something a little bit different this time :

  $env:Path = ';C:\Users\Administrator\bin\'
  
  $title = "A_Day_for_Cake_and_Accidents"
  
  Start-Process ff-prompt.bat -ArgumentList "ffprobe -show_streams -select_streams v -print_format xml -count_frames C:\Users\Administrator\Desktop\dcp_bearbeitet\$title\$title.mov > C:\Users\Administrator\Desktop\dcp_bearbeitet\$title\totalframes.xml"

  This creates a file called "totalframes.xml" but without the needed information, the only thing I get is :

  C :\Users\Administrator>ECHO OFF

  So basically the console pops up, writes this standard text and does not use my commands which I stated in -Argument-List . I do not have a clue why it is ignoring most of my commands, except for writing everything in a XML file.

• How can I remove downloaded video file after merging video and audio ?

  11 mai 2019, par Locke Jet

  I downloaded 1080p video from youtube using youtube-dl. Video file (.f137.mp4) and audio files (f140.m4a) were downloaded. Them ffmpeg merged the video file and the audio file to mp4 file(.mp4). I want to keep the .f140.m4a file and the .mp4 file, while remove the f137.mp4 file. How can I do ?

  I tried the —exec option in the youtube-dl, but it failed.

  These were my commands :

  root@OMV:~/youtube-dl# cat dl-test.sh
  
  DL_DIR="/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007"
  
  ALBUM="Test"
  
  mkdir -p "$DL_DIR/$ALBUM"
  
  youtube-dl --batch-file  /root/youtube-dl/url-test.list --download-archive /root/youtube-dl/archive-test.list                           \
  
  -f  'bestvideo[ext=mp4]+bestaudio[ext=m4a]/bestvideo+bestaudio'                                 \
  
  --write-sub --embed-sub --all-subs                                                              \
  
  --embed-thumbnail --add-metadata                                                                \
  
  -o "$DL_DIR/$ALBUM/%(title)s.%(ext)s"                                                           \
  
  --exec "rm "$(ls {} | cut -d . -f1)""

  The result were :

  root@OMV:~/youtube-dl# ./dl-test.sh
  
  ls: cannot access '{}': No such file or directory
  
  ...
  
  [ffmpeg] Merging formats into "/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/UpTown Spot.mp4"
  
  ...
  
  [atomicparsley] Adding thumbnail to "/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/UpTown Spot.mp4"
  
  [exec] Executing command: rm  '/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/UpTown Spot.mp4'

  The .mp4 file was deleted, the .f137.mp4 file was still there. I got the opposite result.

  root@OMV:~/youtube-dl# ls '/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test'
  
  UpTown Spot.f137.mp4  UpTown Spot.f140.m4a

  Update 1 :
  I changed to

  --exec "rm "$(ls {} -1 | sed -n '/\.f[0-9]*\.mp4$/p')""

  It still remove the .mp4 file. The output was :

  root@OMV:~/youtube-dl# echo "" > "/root/youtube-dl/archive-test.list"
  
  root@OMV:~/youtube-dl# ./dl-test.sh
  
  ls: cannot access '{}': No such file or directory
  
  ...
  
  [download] /srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/UpTown Spot.mp4 has already been downloaded and merged
  
  ...
  
  [exec] Executing command: rm  '/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/UpTown Spot.mp4'

  Then changed it into :

  --exec "rm "$(ls -1 | sed -n '/\.f[0-9]*\.mp4$/p')""

  The ouput was almost the same :

  root@OMV:~/youtube-dl# ./dl-test.sh
  
  ...
  
  [exec] Executing command: rm  '/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/UpTown Spot.mp4'

  I tested the normal expression in SHELL, it worked :

  root@OMV:~/youtube-dl# cd /srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test
  
  root@OMV:/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test# ls "$(ls  /srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test | sed -n '/\.f[0-9]*\.mp4$/p')"
  
  UpTown Spot.f137.mp4
  
  root@OMV:/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test# rm "$(ls  /srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test | sed -n '/\.f[0-9]*\.mp4$/p')"

  But the similar command running in the youtube-dl —exec option failed !

  Update 2 :
  It seemed that the cmd after pipeline would not be executed.

  root@OMV:~/youtube-dl# ./dl-test.sh
  
  + DL_DIR=/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007
  
  + ALBUM=Test
  
  + mkdir -p /srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test
  
  + youtube-dl --batch-file /root/youtube-dl/url-test.list --download-archive /root/youtube-dl/archive-test.list -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/bestvideo+bestaudio' --write-sub --embed-sub --all-subs --embed-thumbnail --add-metadata -o '/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/%(title)s.%(ext)s' --exec 'ls | grep mp4'
  
  ...
  
  [exec] Executing command: ls | grep mp4 '/srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/UpTown Spot.mp4'
  
  Binary file /srv/dev-disk-by-id-ata-QEMU_HARDDISK_QM00007/Test/UpTown Spot.mp4 matches
