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

  20 septembre 2021, par Gustavo Marinho

  I have code in Python where I need to use FFmpeg to merge an 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 thought the code was working perfectly, but in some cases, the FFmpeg returns "invalid argument", like this example :

  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.

  


• FFmpeg psycho-visual options - psy-rdoq

  7 avril 2020, par SLVR

  I'm new to encoding and I like to do my encodings in x265 10bit. Currently, I'm facing a little issue with ffmpeg. I noticed when I'm using libx265 encoder output file looks a little bit blurred or small detail loss. Code I used to do my encodes is

  



  ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -c:a copy -y output-x26510bit.mkv


  



  I've found out psycho-visual options might help in this case. I modified my code in to

  



  ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -psy-rd 2 -psy-rdoq 4 --rdoq-level 1 -c:a copy -y output-x26510bit.mkv


  



  When I issue the above command, I get an error code

  



  C:\Users\abc\Desktop\1>ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -psy-rd 2 -psy-rdoq

  How do I solve this issue

  


• On Heroku I got FFMPEG::Error (Failed encoding.Errors : encoded file is invalid. Full output : )

  8 octobre 2020, par Ruslan Valeev

  The code is :

  


  tempfile = Tempfile.open('content')
tempfile.write(content)
movie = FFMPEG::Movie.new(tempfile.path)
screenshot_temp_file = Tempfile.open('screenshot')
movie.screenshot(screenshot_temp_file.path)


  


  everything works fine locally, but when I try this on Heroku I got error at last row :

  


  irb(main):013:0> movie.screenshot(screenshot_temp_file.path)&#xA;I, [2020-10-07T15:48:27.132114 #7]  INFO -- : Running transcoding...&#xA;["/app/vendor/ffmpeg/ffmpeg", "-y", "-i", "/tmp/content20201007-7-1g1955b", "-vframes", "1", "-f", "image2", "/tmp/screenshot20201007-7-1mmts7s"]&#xA;&#xA;E, [2020-10-07T15:48:27.190572 #7] ERROR -- : Failed encoding...&#xA;["/app/vendor/ffmpeg/ffmpeg", "-y", "-i", "/tmp/content20201007-7-1g1955b", "-vframes", "1", "-f", "image2", "/tmp/screenshot20201007-7-1mmts7s"]&#xA;&#xA;&#xA;Errors: encoded file is invalid. &#xA;&#xA;Traceback (most recent call last):&#xA;        7: from /app/bin/irb:30:in `<main>&#x27;&#xA;        6: from /app/bin/irb:30:in `load&#x27;&#xA;        5: from /app/vendor/ruby-2.6.6/lib/ruby/gems/2.6.0/gems/irb-1.0.0/exe/irb:11:in `<top>&#x27;&#xA;        4: from (irb):13&#xA;        3: from /app/vendor/bundle/ruby/2.6.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/movie.rb:204:in `screenshot&#x27;&#xA;        2: from /app/vendor/bundle/ruby/2.6.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:45:in `run&#x27;&#xA;        1: from /app/vendor/bundle/ruby/2.6.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file&#x27;&#xA;FFMPEG::Error (Failed encoding.Errors: encoded file is invalid.

  I've try to pass some options, like :seek_time and validate: false but nothing changed. What am I doing wrong ? Thank you so much !

  


  EDIT :
After Full output: ) there is nothing.
I've install FFMPEG buildpack on Heroku, and can see it in ui :
