  How do I tell ffmpeg that /tmp/phpFm6H79 is a safe filename ?

  


  When I do

  


  ffmpeg -y -f concat -i '/tmp/phpFm6H79' -c:v:libx264 -vsync vfr '/home/hans/projects/test/output2.mp4'


  


  I get (*only the last 2 lines are interesting)

  The filepath is generated with PHP's tmpfile() like

  


  $ffmpegInputTxtFileHandle = tmpfile();
$ffmpegInputTxtFilePath = stream_get_meta_data($ffmpegInputTxtFileHandle)['uri'];


  


  The code should be threadsafe, so using hardcoded paths is not really viable, and using tmpfile() is very convenient, it takes care of automatically deleting the file when the script exit, even if php crashes, so I'd rather tell ffmpeg that it is safe, than change it to something other than tmpfile(), is it possible ? how ?

  


  I tried using this fugly workaround to get it to end with ".txt"

  


          $ffmpegInputTxtFileHandle = tmpfile();
        $ffmpegInputTxtFilePath = stream_get_meta_data($ffmpegInputTxtFileHandle)['uri'] . ".txt";
        fclose($ffmpegInputTxtFileHandle);
        $ffmpegInputTxtFileHandle = fopen($ffmpegInputTxtFilePath, 'w+b');
        register_shutdown_function(function () use ($ffmpegInputTxtFileHandle, $ffmpegInputTxtFilePath) {
            @fclose($ffmpegInputTxtFileHandle);
            @unlink($ffmpegInputTxtFilePath);
        });


  


  but it even says that /tmp/phpFm6H79.txt is an unsafe filename :'(

  


• ffmpeg - cut without reencoding and strange behaviour : application provided duration is out of range for mov/mp4 format [closed]

  27 août 2023, par user2707175

  In Ubuntu 18.04 I quite often used the following command for trimming part of the video without re encoding (which means without any quality loss).

  


  ffmpeg -ss 00:06:00 -i DSCF5984.MOV -t 00:07:00 -c copy DSCF5984_A_wszystkie.MOV

  


  Not so much time ago I moved to Ubuntu 22.04. Still having the same video camera and still using the same format for recording, when using the command as above I'm getting quite strange error and the behavior is unexpected. In this case mov file is 40 sec file. I want to get 7 seconds fragment starting from 6 second (thus from 6 to 13 sec). Instead of this I get very short fragment from the beginning of the file. I don't even know how long as none of video players want to display its length. Probably it's 1-2 sec. Thus it's not only, I get this error, but ffmpeg doesn't work. In theory I have the newest version available for ubuntu 22.04.

  Is that some kind of error ? Or should I do sth different ? I'm quite surprised as I didn't change my camera. So is that sth changed in ffmpeg ?

  


• How to resolve Electron ffmpeg error opening input file ?

  26 août 2023, par 3V1LXD

  I have an Electron app with ffmpeg.exe inside the project's bin folder. When i try to use ffmpeg to make a new video I get an error reading the input file.

  


  FFmpeg error: [in#0 @ 000002667f2ab9c0] Error opening input: No such file or directory
