• FFmpeg return 'invalid argument' only for some runs, even tought is the same code

  20 septembre 2021, par Gustavo Marinho

  I have a code in python where i need to use FFmpeg to merge a audio and a video downloaded using pytube together :

  


          for video in p.videos:
            video.streams.filter(file_extension='mp4',resolution='480p')[0].download(parent_dir+'/mp4/processing/video')
            print(video.streams.filter(only_audio=True)[1].download(parent_dir+'/mp4/processing/audio'))

            subprocess.run([

                r'c:\FFmpeg\bin\ffmpeg', '-i',
                os.path.join(parent_dir+'/mp4/processing/video',video.streams.filter(file_extension='mp4',resolution='480p')[0].default_filename)
                ,'-i',
                os.path.join(parent_dir+'/mp4/processing/audio',video.streams.filter(only_audio=True)[1].default_filename),
                '-c:v','copy','-c:a','copy',
                os.path.join(parent_dir+'/mp4',video.streams.filter(file_extension='mp4',resolution='480p')[0].title+'.mp4')

            ])


  


  I tought the code was working perfectly, but in some cases, the FFmpeg returns "invalid argument", like this example :

D:/videos/mp4\Dropkick Murphys - "Rose Tattoo" (Video).mp4: Invalid argument


  


  For some reason, the FFmpeg say that my output name is invalid, but i don't understand why, given that i ran the code multiple times before and it worked perfectly

  


  Thanks in advance, sorry for my bad english :3

  


• Laravel FFMpeg - FFMpeg cannot edit existing files in-place

  28 septembre 2020, par wlaskovic

  After I wanted to upload a video in the queue was returned a failed job.

  


   [2020-09-25 13:24:25][125] Processing: App\Jobs\ConvertVideoForStreaming <br /> [2020-09-25 13:24:26][125] Failed:     App\Jobs\ConvertVideoForStreaming&#xA;

  


  So I've took from the DB failed_jobs table the response and run the following :

  


    C:\ffmpeg\bin\ffmpeg.exe -y -i "C:\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4" -threads 12 -vcodec libx264 -acodec libmp3lame -b:v 500k -refs 6 -coder 1 -sc_threshold 40 -flags +loop -me_range 16 -subq 7 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -trellis 1 -b:a 128k -vf "[in]scale=720:360 [out]" -pass 1 -passlogfile "C:\Users\wlask\AppData\Local\Temp\ffmpeg-passes5f6dd36a4519fd1fev/pass-5f6dd36a452c9" "C:\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4"


  


  Which returned the following :

  Output C :\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4 same as Input #0 - exiting

  


  FFmpeg cannot edit existing files in-place.

  


  


  This was returned after i've run the command from DB failed jobs table return.

  


  How should I solve this ?

  


• Anomalie #4546 : image_recadre perd l’EXIF de rotation

  19 septembre 2020, par jluc -

  Le 19/07/2020, cerdic dit « 
  On pourrait envisager que conserver les exifs à travers chaque filtre image, mais c’est aussi dangereux du point de vue des données personnelles. Je verrais plutôt un filtre qui permettrait de recopier certains exifs d’une image source sur l’image finale, sur le mode :
  

  <span class="CodeRay">[(#FICHIER|image_reduire{…}|image_recadre{…}|image_copie_exif{#FICHIER,’author’})]
  
  </span>
