• FFmpeg image to video conversion error : [image2] Opening file for reading

  14 février 2018, par user1690179

  I am running ffmpeg on an AWS Lambda instance. The Lambda function takes an input image and transcodes it into a video segment using ffmpeg :

  ffmpeg -loop 1 -i /tmp/photo-SNRUR7ZS13.jpg -c:v libx264 -t 7.00 -pix_fmt yuv420p -vf scale=1280x720 /tmp/output.mp4

  I am seeing inconsistent behavior where sometimes the output video is shorter than the specified duration. This happens inconsistently to random images. The same exact image sometimes renders correctly, and sometimes is cut short.

  This behavior only happens on Lambda. I am not able to replicate this on my local computer, or on a dedicated EC2 instance with the same environment that runs on lambda.

  I noticed that when the output video is short, the ffmpeg log is different. The main difference are repeated [image2 @ 0x4b11140] Opening '/tmp/photo-2HD2Z3UN3W.jpg' for reading lines. See ffmpeg logs below.

  Normal execution with the correct output video length :

      ffmpeg -loop 1 -i /tmp/photo-SNRUR7ZS13.jpg -c:v libx264 -t 7.00 -pix_fmt yuv420p -vf scale=1280x720 /tmp/video-TMB6RNO0EE.mp4

  As requested, here is a link to the full log. In this log - ffmpeg renders only 323 out of 375 frames.

  The Opening '/tmp/photo-2HD2Z3UN3W.jpg' segment repeats many many times until it finally renders out a short video. Does anyone have insight into why it keeps opening the image file ? This must have something to do with the underlying issue.

• How to keep transparency when scale webm file with ffmpeg

  5 octobre 2022, par Sonia Kidman

  I'm using ffmpeg to scale my WEBM file, by using below command : 
ffmpeg -i in.webm -c:v libvpx -vf scale=100:100 out.webm
The output has correct resolution as I expected but the problem is transparency become black background.

  



  Could someone give me a solution for this.

  



  Thank you so much.

  



  Below is the log of the operation :

• FFMPEG does not add images to audio

  20 février 2018, par Googlebot

  I want to create a slideshow with a background music by ffmpeg, and use the command

  ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

  and map.txt is like

  file '1.jpg'
  
  duration 15
  
  file '2.jpg'
  
  duration 60

  The result is a video with the audio and blank background. If I run the above command without audio as

  ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4

  a perfect video of the images (the intended slideshow) is generated (but obviously without audio).

  I reckon the problem is related to synchronising the audio and images.

  This is the terminal output for the first command

  ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4
