• Why does ffmpeg keep using more and more RAM and crash ?

  29 décembre 2022, par József Márton Kakas

  I am using the following command with ffmpeg to encode a video file using the libsvtav1 codec : ffmpeg -i hevc.mkv -map 0:v:0 -c:v:0 libsvtav1 -preset 8 -crf 22 -format matroska av1.mkv.

  


  However, ffmpeg is using up all of my available RAM and crashing. I have also tried using the libx264 codec, but the same issue occurs, although it happens more slowly. I have already allocated 12 GB of RAM to ffmpeg, but it still seems to be insufficient. How can I prevent ffmpeg from using all of my available RAM and crashing when using either the libsvtav1 or libx264 codecs ?

  


  I have tried it on another VM, but the same issue occurs. Here is the full output of the program.

  


  ffmpeg -i akira.mkv -map 0:v:0 -c:v:0 libsvtav1 -preset 8 -crf 22 -c:a copy -c:s copy -format matroska av1.mkv

• ffmpeg strftime no effect on windows

  18 mai 2020, par Ben

  I'm trying to auto mark the output file with timestamps with ffmpeg. Here's my test cmd :

  



  .\ffmpeg.exe -y -loglevel 99 -i test.mp3 -strftime 1 %Y.ogg


  



  I expected a file named 2020.ogg, however only got %Y.ogg. In another word, output filename is not processed by strftime(). I'm using powershell so there should be no relation with cmd's %% escaping.

  



  Here's the output : https://pastebin.com/LUVh2kFA I'm using static builds from https://ffmpeg.zeranoe.com (Thanks Zeranoe !) I confirmed that the problem exists in v4.2.2 and git-20200515. Is there any chance to fix it or am I doing it wrong ?

  


• ffmpeg conversion from MOV to mp4 - how to conserve creation date

  13 juin 2020, par jacobacci

  Windows 10 1909, latest updates.

  



  I am helping a friend move his photos and videos from one Apple ID to another.
I have downloaded all items to my PC using iCloud for PC. I then proceeded to re-upload all the photos to the new Apple ID.
2'000 of the videos are MOV, which I cannot upload to iCloud. I seem to need to convert them to mp4 in order to upload them.

  



  I have converted all of the MOVs to mp4 using the following batch

  



  FOR /F "tokens=*" %%G IN ('dir /b *.MOV') DO ffmpeg -i "%%G" -f mp4 -vcodec copy -acodec mp3 "%%~nG.mp4"


  



  This worked fine and I managed to upload the (now) mp4's to iCloud. Unfortunately all the mp4's now carry yesterday's date as creation date. In iCloud (and on the iPad) all the videos are now displayed with a creation date of 12.6.2020 and it is impossible to find a particular video. Also the context to the photos is lost.

  



  Question :

  



  

  • Is there any way to (batch) convert 2'000 MOV to mp4 while preserving the creation date ?

  


  • alternatively : is there any way to upload the original MOV files to iCloud ?
