• FFMPEG creating static video ?

  10 juillet 2018, par Kjell

  I’m using ffmpeg 4.0.1 on the latest version of MacOS. I’ve got webcam capture down, as well as creating a video from a series of images. But for some reason, when I try to do screen capture, the outputted video is a bunch of colorful static with the correct audio.

  Here is the command I use :

    ffmpeg -f avfoundation -i '1:0' -y -r 30 -pix_fmt yuv420p test.mp4

  And here are my devices :

  [AVFoundation input device @ 0x7f9924404b00] AVFoundation video devices:
  
  [AVFoundation input device @ 0x7f9924404b00] [0] FaceTime HD Camera

  [AVFoundation input device @ 0x7f9924404b00] AVFoundation audio devices:
  
  [AVFoundation input device @ 0x7f9924404b00] [0] Built-in Microphone

  And here is some of my config :

  Anyone have an ideas on how to fix this ?

  Update with Terminal Log

  I reran the terminal command, let it run for 30s, and then canceled the operation.

  To note : I added -pix_fmt yuv420 because without it, none of my ffmpeg output seems to be able to run via Quicktime Player. Since this is the only player I use currently, I want my output to run on this player. I noticed there is a log about switching to uyvy422, but I think this is a bug because when I manually add uyvy422, the output cannot be opened at all.

• Automating FFmpeg/ multi-core support

  23 juillet 2018, par Pablowako

  I need help with FFmpeg/batch. I have a couple of large batches of images (+14000 files each batch, +5 MB each image, .TIFF all of them) and I’m stringing them together into a .mp4 video using FFmpeg.

  The date in the metadata is broken because of the way they’re stored upon creation, so the time and date (T/D) are on the file_name. I need each frame to have its respective T/D (so its File_Name) burnt onto them for accurate measurements (scientific purpose).

  With the help of google and reddit, I’ve managed to semi-automate it like so :

  Master.bat :

  forfiles /p "D:\InputPath" /m "*.TIFF" /S /C "cmd /c C:\SlavePath\slave.bat @file @fname"

  Slave.bat :

  ffmpeg -i "%~1" -vf "drawtext=text=%~2: fontcolor=white: fontsize=30: fontfile='C\:\\FontPath\\OpenSans-Regular.ttf'" "D:\OutputPath\mod_%~1"

  Running Master.bat will output each individual image with the text burnt onto them and change the File_Name to mod_'File_name'.TIFF

  Real example : 2018-06-05—16-00-01.0034.TIFF turns into mod_2018-06-05—16-00-01.0034.TIFF

  The problem is that FFmpeg doesn’t like it when my files have "—" in them ("date—time.miliseconds.TIFF") and doesn’t like the miliseconds either, so I have to change the name of all files "manually" using Bulk Rename Utility (BRU). So, using BRU I rename all files to 00001.TIFF, 00002.TIFF, etc. and FFmpeg likes me again. It works great, but it means I can’t be AFK.

  After that, I have to go back to cmd and manually start the image to video conversion.

  Also, FFmpeg doesn’t seem to be using all cores.

  ---

  I need help finding a way to :

  1. Change master.bat’s output to 00001.TIFF etc. automatically in order of processing (i.e. first to be processed is 1.TIFF, 2nd is 2.TIFF)
  2. Add ffmpeg’s img-to-vid function to the automating system
  3. Get my CPU to use all the cores effectively if possible. 2014/15 posts found on google make it seem as though FFmpeg doesn’t support multi-core or hyperthreading.
