• ffmpeg segmentation filter don't works with strftime filename template

  24 juillet 2020, par Ksnadr Renderon

  I try to run ffmpeg with segment filter and timestamp filename template :

  


   ffmpeg -f v4l2 -framerate 30 -video_size 960x720 -i /dev/video0  -f segment  -segment_time 5  -reset_timestamps 1 -segment_format mp4 -strftime 1 out%Y-%m-%d_%H-%M-%S.mp4


  


  and i got error :

  


  Invalid segment filename template 'out%Y-%m-%d_%H-%M-%S.mp4'


  


  I have read a lot of posts and questions in the internet with the same arguments (after input, which is specific) and people says that this works. What wrong with my command ?

  


  UPD : add full ffmpeg log

  


  root@nanopiair:~# ffmpeg -f v4l2 -framerate 30 -video_size 960x720 -i /dev/video0  -f segment  -segment_time 5  -reset_timestamps 1 -segment_format mp4 -strftime 1 out%Y-%m-%d_%H-%M-%S.mp4

• Windows 10 EV code signing no longer works on electron app

  23 février 2021, par SoOhNo

  I have an electron app. Pretty basic app. It doesn't use ffmpeg for anything it does play an mp3 chime from time to time. I build my app with electron-forge using squirrel format. I then sign it using the SafeNet Authentication app. It's always worked flawlessly.

  


  It's been a couple months since I last released a version. Only thing that has changed is some html ui updates within my electron app and of course lots of Windows 10 updates.

  


  My app builds fine using electron-forge, it installs and runs without issue. I then sign it like usual from the command line and SafeNet confirms it was signed. Right clicking on the file shows it has been signed by my organization. However, once I execute the signed app I get this error : "The code execution cannot proceed because ffmpeg.dll was not found. Reinstalling the program may fix this problem."

  


  Here is what I have tried so far :

  


  

  • Building/Signing on a different windows 10 machine.

  


  • Uninstall/Reinstall SafeNet.

  


  • Running signed .exe on a different Windows 10 instance

  


  • Building/Signing with a cmd session ran as administrator

  


  


  I am at a loss, why is it screaming about ffmpeg.dll which my app doesn't depend on ? Why only after the .exe has been signed do I get this error ?

  


  OS : Windows 10
  
Electron v7.3.2
  
Electron-Forge/cli v6.0.0-beta.47
  
SafeNet x64 v10.3

  


• Why my ffmpeg command works only first several minutes ? [closed]

  2 mars, par О. Войтенко

  I have my own ffmpeg exec command in the docker for writing rtsp stream by motion detection and make segments every 60 sec. But This command detect correctly only first 1-2 minutes, and without any errors ffmpeg does not detect motion. I'm using the latest version ffmpeg.

  This command uses tmpfs and then inotifywait copy ready file to the storage, image built - ffmpeg + inotify. This is par of my program. But main issue is that this configurftion does not work correctly.
