• ffmpeg error when try co concat videos with filter_complex

  29 août 2023, par Matteo Pasini

  I'm trying to concatenate two videos with different resolutions. Reading around I saw that before being able to concatenate them I should scale them to the same resolution, but the command I'm using (the same one they propose on stackoverflow) doesn't seem to work. Does anyone have any ideas ?

  


  Command :

  


  ffmpeg -i file1.mp4 -i file2.mp4 -filter_complex "[0:v]scale=1024:576:force_original_aspect_ratio=1[v0]; [1:v]scale=1024:576:force_original_aspect_ratio=1[v1]; [v0][0:a][v1][1:a]concat=n=2:v=1:a=1[v][a]" -map [v] -map [a] output.mp4


  


  Output :

• FFmpeg filter_complex to merge audio from two files fails without an error due to album cover PNG stream

  13 décembre 2023, par kaushal

  When you run FFmpeg filter_complex command to process two mp3 files and merge them into one, the command runs successfully, the output mp3 file is generated. No errors are reported. But the output fails to run. The result log from FFmpeg looks something like this, which points to an PNG stream in one of the mp3.

• How to tell ffmpeg that /tmp/phpFm6H79 is a safe file name ?

  28 août 2023, par hanshenrik

  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)

[concat @ 0x55b070e9ff40] Unsafe file name '/tmp/phpbshsmF'
/tmp/phpFm6H79: Operation not permitted


  


  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 :'(
