• Evolution #4754 : Mettre à jeu le jeu des icônes de extensions

  30 avril 2021, par b b

  Amha, SVG partout et zou, et si nécessaire on pourra générer du PNG en masse à partir des SVG.

  Je proposais donc le pack Yaru https://github.com/ubuntu/yaru/tree/master/icons/src/fullcolor/mimetypes (icônes d’Ubuntu) complet, sobre mais il est trop coloré et "en relief" maintenant qu’on est plutôt en mode flat sur le jeu d’icônes du privé, exemples :

  Sinon, il y a aussi Papirus & Vimix, et surtout Numix qui est très fourni :

  Because the two cameras have a same device name, I couldn't stream two videos using this simple command at a same time : ffplay -f dshow -i video=Microsoft® LifeCam Studio(TM).
  
So I used pin names following the ffmpeg dshow example.
The only thing I could check was Could not find video device with name [video=~~pin name~~] among source devices of type video.

  



  What ffplay command makes enable to stream both videos ?

  


• FFMPEG Start 2 videos at the same time but hide one until the other is finished

  23 mai 2016, par GreenGiant

  I have a generic intro sequence (no audio) and a main video clip. I want the audio from the main clip to play as the intro sequence is playing then the video to switch from the finished intro sequence to the main video. So almost like playing both videos at the same time but hiding one until the other is finished. Is this possible with ffmpeg ? Almost like a send to back function for the video on the main clip (but keep it’s audio rolling so it’s in sync when it shows as the intro clip finishes).
