• Seekbar not working in Chrome

  9 janvier 2014, par mbajur

  I have encoded my video with the following settings chain :

  # line breaks are just for better readability
  
  ffmpeg -y -i /path/to/destination.mp4 
  
         -vcodec libx264 
  
         -acodec libfaac 
  
         -s 640x360  
  
         -movflags faststart  
  
         -aspect 1.7777777777777777 
  
         /path/to/source.mp4

  And, for some reason, it broken the ability to use seekbar in Google Chrome (it works good in Safari). What i have noticed is that the videos were working fine when there is no -movflags faststart setting in above chain. Here is an example of video, which is not working :

  Please note : Seekbar is not working when video download is in progress or it's 100% the first time. If video has been downloaded by chrome player and you refresh the page, seekbar works fine.

• moviepy ruining video after combining them

  1er juin 2020, par jjakeryan

  I'm trying to make a program that downloads videos from TikTok and combines all the separate videos into one .mp4 file and moves the final video to a folder on my desktop. I've been able to make it download all the videos and when I watch the separate videos they play fine however when I combine the videos some of the videos are messed up and look like this but the audio is fine.

  



  #slecting all .mp4 files
    video_files = glob.iglob("*.mp4")

    print(video_files)
    clips = []

    for clip in video_files:  # For each mp4 file name
        clips.append(VideoFileClip(clip))  # Store them as a VideoFileClip and add to the clips list

    today = date.today()

    final = concatenate_videoclips(clips)  # Concatenate the VideoFileClips
    final.write_videofile(f"{today}.mp4", codec="libx264")


#moving completed video to folder on desktop
    shutil.move(f'{today}.mp4', '/Users/jacobmarrandio/Desktop/done_videos/')


  



  thanks for any help

  


• FFMPEG saving frame from video works in localhost but not working in live server

  5 janvier 2018, par Mukesh

  I’m using FFMPEG to take a frame from a video. My code is working all fine in localhost but, fails to execute in server.

  Code I’m executing :

  $ffmpeg = \FFMpeg\FFMpeg::create();
  
  
  
  $video = $ffmpeg->open($File_temp_name);
  
  
  
  $video
  
       ->frame(\FFMpeg\Coordinate\TimeCode::fromSeconds(1))
  
       ->save($saveLocation);

  This code is executing fine in localhost but, when I execute the same in server it is showing an error

  Exception 'FFMpeg\Exception\RuntimeException' with message 'Unable to save framesexception 'Alchemy\BinaryDriver\Exception\ExecutionFailureException' with message 'ffmpeg failed to execute command'

  Command Getting executed is :

  '/usr/bin/ffmpeg' '-y' '-ss' '00:00:01.00' '-i' '/tmp/php02MmoD' '-vframes' '1' '-f' 'image2' '/home/project/public_html/dev/frontend/web/uploads/temp-video-frames/1499319488-act-thumbnail.jpg'

  I’ve tried to execute the command in terminal and found it executing without any error and save frame in desired location. But, when I run it through my code it is throwing above error
