• Only trim video without encoding laravel ffmpeg

  1er mai 2021, par gyd128

  I would like to ask if the possibility of using ffmpeg laravel in such a way that when cutting a movie it does not convert it to mp4 a second time ? I'm sending the code as it looks at the moment. There is an option on github to use CopyFormat, use ProtoneMedia \ LaravelFFMpeg \ FFMpeg \ CopyFormat; unfortunately it doesn't work on my example. Maybe someone will be that good and guide me to the answer. Sorry for my English

  


    $ffmpeg = \FFMpeg\FFMpeg::create();
        $video = $ffmpeg->open('../../filmy/'.$path);
        $video->filters()->clip(\FFMpeg\Coordinate\TimeCode::fromSeconds($start), \FFMpeg\Coordinate\TimeCode::fromSeconds($end));
        $video->save(new \FFMpeg\Format\Video\X264('libmp3lame'), '../../filmy/conversion/s.mp4');


  


• SNAP : Simulation and Neuroscience Application Platform [closed]

  19 avril 2024, par S_S

  Is there any documentation/help manual on how to use SNAP (Simulation and Neuroscience Application Platform)1.

  



  I wanted to run the Motor Imagery sample scenario with a .avi file for the stimulus instead of the image. How can that be done ?

  



  The following error is obtained when using the AlphaCalibration scenario which gives code to play an avi file.Any help appreciated

• ffmpeg snap permission denied accessing encrypted folder

  30 décembre 2020, par Eric M

  I'm on Ubuntu 18.04 and have most of my home folder in an EncFS filesystem. I have ffmpeg installed as a snap and it won't access files in the EncFS filesystem.

  


  cannot open path of the current working directory: Permission denied


  


  It also had the same error when accessing any folder not part of /home partition (for example on a second mounted harddrive) and also smb shares. I tried adding the removable-media connection but no joy. In fact I tried adding every connection. I do have a workaround for the other harddrives and the smb share by installing in —devmode (obviously not ideal). Is this a bug or a lack of snap understanding on my part ?

  


  Thanks !
