• FFMPEG Add thumbnail to video [duplicate]

  18 mai 2020, par james-norman

  add a thumbnail to my video file. I have the code that I have compiled with the help of other people from StackOverflow and I have one bit left to finish it off and that is to add a line of code to add video thumbnail.
  

  



  you will see some weird text in command like targggget these are words that get replaced by the software so ignore it.

  
app.path\ffmpeg gets replaced with file-path/ffmpeg
  
targgggett\targ3et.mp4 file-path/xx.mp4
  
targgggett\targetimgee - output is example C :\Users\username\Desktop\vidz\New folder\images\demo.png

  



  "app.path\ffmpeg" -y -i "targgggett\targ3et.mp4" -loop 1 -framerate 30000/1001 -t 5 -i "targgggett\targetimgee" -t 0.5 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -filter_complex "[0:a]atempo=1.0,pan=stereo|c0code>

  



  i want to add a video thumbnail using targgggett\targetimgee and set video thumbnail only

• Does exists other way of indenting ffmpeg batch script ?

  22 mars 2021, par Toni Cambronero Garcia

  How can I indent code in a Batch script other than using temporal variables %= =% ?
This is the only code that works for me with indentation.

  If I try to use spaces or tabs in the "-vf" section ffmpeg interprets them as the end of the filter and the start of the output file argument .
