• Using ffmpeg to watermark a folder of videos

  25 août 2018, par user5947524

  I am using the code below to watermark individual videos one-by-one in a folder :

  ffprobe -v quiet -show_entries stream=width,height -of default=noprint_wrappers=1 dave.mp4
  
  ffmpeg -i logo.png -y -v quiet -vf scale=width*0.15:-1 scaled.png
  
  ffmpeg -i dave.mp4 -i scaled.png -filter_complex "overlay=10:main_h-overlay_h-10" dave2.mp4

  The first line gets the width and the height of a video, second line scales the watermark for that video, third line creates a new video watermarked.

  How can I make run for a full folder of 1000 videos ?

  I tried the code below but it corrupted the videos :

  for %%a in ("C:\Users\Work\Desktop\test2\*.mp4") do (
  
   ffprobe -v quiet -show_entries stream=width,height -of default=noprint_wrappers=1 "%%a" 
  
   ffmpeg -i logo.png -y -v quiet -vf scale=width*0.15:-1 scaled.png 
  
   ffmpeg -i "%%a" -i scaled.png -filter_complex "overlay=10:main_h-overlay_h-10" "C:\Users\Work\Desktop\test2\%%~na.mp4"
  
  )

  The error I get is :

  [mov,mp4,m4a,3gp,3g2,mj2 @ 0000014545aaaa00] stream 0, offset 0x18039: partial file

• ffmpeg giving conversion failure when run on subclips

  20 août 2018, par user2333839

  I have a main video clip and I am generating a subclip out of it using ffmpeg. The command i use to generate the subclip is :

  ffmpeg -i {input_video} -ss {start_time} -to {end_time} {output_filename}

  Once I have the subclip, I am doing the following things :

  Step 1 : I am calculating the average Frame Rate using ffprobe :

  ffprobe -v error -select_streams v:0 -show_entries stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1 <input file="file" />

  Step 2 : I am extracting the raw video stream and storing it in a temp location and removing the existing PTS values using :

  ffmpeg -i <input video="video" /> -c:v copy -an $TMP_STREAM 2>&amp;1

  Step 3 : I am remuxing the video to a container forcing the average FPS causing the PTS values to be rewritten :

  ffmpeg-r <fps> -i $TMP_STREAM -c:v copy $OUTPUT_FILE 2>&amp;1
  
  </fps>

  When I do the above 3 steps on the main video clip, it works just fine. But when I do these steps on the subclip (which I generated using ffmpeg), then step 3 is giving me error :

  Can't write packet with unknown timestamp
  
  av_interleaved_write_frame(): Invalid argument

  Any inputs on what might be happening ?

  Below are my commands and the logs :

  Command 1 :
  ffprobe -v error -select_streams v:0 -show_entries stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1 abcd.mp4.

  ---> Output : 287/12

  Command 2 :
  ffmpeg -i abcd.mp4 -c:v copy -an /tmp/tmp.h264 2>&1
