• bash - Parse folder name, generate gif from images inside using ffmpeg

  16 janvier 2023, par BestMordaEver

  I have 150 folders with some nasty folder structure. Inside are animation frames helpfully named 1.png, 2.png and so on. I need to generate gifs from those images and have them named properly. Here's how I'd handle this case by case :

  


  Folder ./dragon/raw/bodies/dragon/green/old/5/down/idle has 25 .png files. I run the following commands :

  


  # pngs to gif
ffmpeg -framerate 12 -start_number 1 -i ./dragon/raw/bodies/dragon/green/old/5/down/idle/%d.png dragon-green-old-5-down-idle-intermediate.gif

# gif to boomerang gif
ffmpeg -i dragon-green-old-5-down-idle-intermediate.gif -filter_complex "[0]trim=start_frame=1:end_frame=29,setpts=PTS-STARTPTS,reverse[r];[0][r]concat=n=2:v=1:a=0,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" dragon-green-old-5-down-idle.gif

# remove the intermediate gif
rm dragon-green-old-5-down-idle-intermediate.gif


  


  Note : relevant part of the name for gif is whatever's after /raw/bodies

  


  Question : how do I put this in a loop that would iterate over all the nested folders, parse their names and feed the result in the commands above ?

  


  Bonus question : is there a way to merge the two commands and create the boomerang gif immediately, removing the need in intermediate files ?

  


• How to video-record selenium tests running headless inside a docker ?

  1er juin 2021, par Alex

  I am running python-selenium tests inside a docker using a headless firefox.

  


  During these tests I am able to make screenshots with the selenium method for screenshots - but can I use something to 'video' record the virtual display during the whole test (several test scripts with several test methods, with many webdrivers started and stopped).

  


  So how can I video-record a complete test session ?

  


  Addendum : I have found a webpage that describes exactly what I need : here. Unfortunately I get an error when I try to do the recording. Here are the commands I am doing :

  


  xvfb-run --listen-tcp --server-num 44 --auth-file /tmp/xvfb.auth -s "-ac -screen 0 1920x1080x24" python seltest.py &
ffmpeg -f x11grab -video_size 1920x1080 -i 127.0.0.1:44 -codec:v libx264 -r 12 /tmp/behat_1.mp4


  


  and the error is (for the second command) :

  


  [x11grab @ 0x1d289c0] Cannot open display 127.0.0.1:44, error 1.
127.0.0.1:44: Input/output error
