• ffmpeg does not recognize used codec in any way

  26 janvier 2021, par Omid Ki

  I am using ffmpeg-python to combine video and audio in my program but for one video file I constantly get this error :

  It just doesn't recognize it. I know that the codec is av01 I have tried passing it in as the vcodec keyword but nothing would work. I tried going to cmd directly and adding to the 'analyzeduration' and 'probsize' but nothing seems to work. How can I fix this ? My code :

  


  import ffmpeg

# I have tried passing absolute paths instead of relative ones too, still not working
input_video = ffmpeg.input("temp/Above NYC - Filmed in 12K.mp4")
input_audio = ffmpeg.input("temp/audio_temp 1.webm")
full_path = "temp/New.mp4"
out = ffmpeg.output(input_video, input_audio, full_path, vcodec='copy', acodec='aac', strict='experimental')
out.run(overwrite_output=True)


  


• Creating thumbnail using ffmpeg for video downloaded from youtube

  24 septembre 2015, par akhila

  Thanks in advance. I have trouble creating thumbnail for videos downloaded from youtube . I have downloaded videos using the youtube downloader extension and saved to mp4 format , When I upload a video to my site I use ffmpeg to create the thumbnail of the videos , For other mp4 videos it works perfectly fine but for youtube videos. Youtube videos are uploaded to the site and thumbnail creation not working. Here goes my code.

       system('ffmpeg -i '.$saveimgpath1.' -ss 00:00:00.010 -vframes 1 '.$thumbpath);

  The path given is correct as it works for other videos.Any help will be greatly appreciated .

• Automating Basic Video Editing [closed]

  2 février, par user29470652

  What's guys ! I am a beginner in programming.

  


  As of now, I have created a basic YouTube downloader with the help of Python, FFmpeg, yt dlp, and Flaskapp.

  


  Now, I am automating the basic video editing part ( Turn bulk video files into a basic similar edit like we have one template then we add a caption from the title of the video, then place the video in the center of the template trim out to meet the video length of the given video then saving it) with the help of FFmpeg.

  


  Has anyone already tried or built it ?? Any marketer or video editor ??

  


  I am halfway to the project

  


  Here is theenter image description here

  


  I am halfway through the project and wonder if anyone has ever done it before like any video editor or marketer ??
