  I am converting png images into a video using ffmpeg.

  My png file names are like this :

  image1_xy.png
  
  image2_xy.png
  
  image3_xy.png
  
  image4_xy.png
  
  ...
  
  image10_xy.png
  
  image11_xy.png
  
  ...
  
  image100_xy.png
  
  image101_xy.png
  
  ...

  my script is the following :

  ffmpeg -r 1 -f image2 -s 1920x1080 -i image%03d.png -vcodec libx264 -crf 25  -pix_fmt yuv420p test.mp4

  which is working only when the file names are like image001.png , image002.png...

  How should i modify this to take into account the file name pattern I have ?

  update

  i don’t mind if the answer suggests to use a bash script to rename files in the order they appear with the right pattern.

  avcodec/flashsvenc : Fix packet size calculation
  The earlier code did not account for the frame header as well
  
  as the block headers ; furthermore, in case a large part of
  
  a block is unused (due to padding), the output size may
  
  exceed 3 * width * height (where the dimensions correspond
  
  to the visible pixels) due to the overhead of the zlib header,
  
  so use the padded dimensions to calculate the maximum packet size
  
  (which is also what the actual call to compress2() uses).
  
  Fixes ticket #10053.

• FFMPEG - Converting MKV to MP4 on Gdrive using rclone mount. ERROR : output file #0 does not contain any stream

  30 avril 2020, par Enrique Torrez

  I am trying to convert video files from my back-up rip files library that I have on my Gdrive account. I was successfully able to set up a dedicated server + plexserver + rclone + gdrive. I have files that are big and my family are not able to stream them due to the poor internet service that I have in my country. So I am trying to reduce the file size so it can be streamed directly

  



  My rclone mount script is :

  



  rclone mount gcache: /path  --tpslimit 5 --allow-other --acd-templink-threshold 0 --stats 1s --buffer-size 64M --timeout 5s --contimeout 5s --max-read-ahead 1G --drive-chunk-size 64M -vv &


  



  And my ffmpeg script is :

  



  ffmpeg -i origen.mkv -c:v copy -movflags faststart -strict -2 convertedfile.mp4


  



  I had the following errors :

  



  moov atom not found


  



  I used this command :

  



  AtomicParsley myVideo.mp4 -P


  



  Now when I execute

  



  ffmpeg -i convertfile.mp4


  



  I get this error :

  



  Output file #0 does not contain any stream


  



  What am I doing wrong ? I need some help please.
