  ffmpeg -i input.mp4 -i 1.png -i 2.png -filter_complex "amovie=test.m4a:loop=0,volume=0.2[a2];[0]volume=0.5[a1];[a1][a2]amix[a3];[0][1]overlay=0:0:enable='between(t,2,5)'[ovrlay]" -map [ovrlay] -map [a3] -shortest -t 11 testVolumemp4AMixCheck.mp4

• FFMPEG on Heroku exceeds memory quota in testing

  5 juillet 2022, par Patrick Vellia

  After following this tutorial, and getting it to work locally on my own development environment, before really getting my hands dirty and working deeper on my own project implementation, I decided to push it up to Heroku to test in a staging environment.

  


  I had to have Heroku add the FFMPEG build-pack and turn on the Redis Server for ActionCable to work.

  


  I didn't link the staging to a cloud storage bucket on Google or Amazon yet, just allowed it to upload directly to the dymo disk for testing. So it would go into the storage directory as it would in development for now.

  


  the test MOV file is 186 MB in size.

  


  The system uploaded the file fine.

  


  According to the logs, it then copied the file from storage to tmp as the tutorial has us do.

  


  Then it called streamio-ffmpeg's transcode method.

  


  At this point, Heroku forcibly kills the dymo because it far exceeds the memory quota.

  


  As this is a test environment, it's only on the free tier of Heroku.

  


  I'm thinking I won't be able to directly process video projects on Heroku itself, unless I'm wrong ? Would it be better to call an API like Cloud Functions or Amazon Lambda, or spin up a Compute Engine long enough to process the FFMPEG command ?

  


• BASH recursive go trough all subdirectories and if a specific file existis, touch all files from one type in this directory [duplicate]

  20 décembre 2023, par mkirbst

  I have a music collection of the structure Interpret -> Album -> song1.m4a song2.m4a cover.jpg

  


  I can use ffmpeg to add the cover.jpg to the files :

  


  #! /bin/bash

COVER=./cover.jpg

if test -f "${COVER}"
then
    for f in ./*.m4a
    do
        echo "Adding ${COVER} for ${f}"
        mv ${f} tmp.m4a
        ffmpeg -i tmp.m4a -i ${COVER} -map_metadata 0 -map 0 -map 1 -acodec copy ${f} && rm tmp.m4a
    done
else
    echo "No ${COVER} found. Aborting..."
fi


  


  How can I modify my script to do that ?

  


  What it does : when there is a cover.jpg in the folder, then add this folder lossless to all m4a audio files.
BUT : It seems that this does not work for all folders. It would be nice to just cd to the main music folder instead of going to every album folder and run the script above by hand.

  


  What it should do :

  


  

  1. go to every subfolder

  


  2. if there is a cover.jpg file then proceed at 3. if not go to step 1. (next subfolder)

  


  3. for every m4a in this folder embed the cover.jpg into every m4a file in this subfolder
