• PermissionError : [WinError 5] Access is denied when trying create VideoFileClip object for video

  7 février 2019, par Alex Goft

  Im using python 3.6 and this is a module from my project -

  import os
  
  import time
  
  
  
  from moviepy.video.io.VideoFileClip import VideoFileClip
  
  
  
  def add_audio_to_file(original_video, dest_video):
  
      suffix = original_video.split(".")[-1]
  
      directory_path = os.path.dirname(dest_video)
  
      temp_name = os.path.join(directory_path, "temp_vid_{}.{}".format(time.time(), suffix))
  
      os.rename(dest_video, temp_name)
  
  
  
      os.chmod(original_video, 777)
  
  
  
      orig_videoclip = VideoFileClip(original_video)
  
      audioclip = orig_videoclip.audio
  
      redorded_videoclip = VideoFileClip(temp_name)
  
      with_audio_clip = redorded_videoclip.set_audio(audioclip)
  
      with_audio_clip.write_videofile(dest_video, progress_bar=False, threads=6, verbose=False)
  
      os.remove(temp_name)

  I get the following error :

  I checked the permissions and everything seems ok. In addition, i tried to change the permissions using os.chmod(original_video, 777), but still without any success.

• ffmpeg for a android (using tutorial : "ffmpeg and Android.mk")

  13 septembre 2023, par Matthias

  I am trying to compile ffmpeg for a android. I have found several posts on this theme but non of these seems to work. If tried to build ffmpeg like it is posted on [1]. Did anybody successfully compile ffmpeg using theses tutorial ?
I am not sure how to realize step 4 to 5.

  



  


  STEP4 : Configuring ...

  
 


  STEP5 : cd to your NDK root dir, type make TARGET_ARCH=arm APP=ffmpeg-org

  


  



  It seems to me that building an application like it is explained in the tutorial in step 5 need some previous steps. Unfortunately I have no app in the folder to make. I am using the current android ndk release 3 and checked out the actual ffmpeg releases from [3] and [4]. I am thankful for every advice.

• UDP to MP4 transcoding via ffmpeg

  30 juillet 2013, par Andrew J. Freyer

  I have not been able go find any substantial documentation to answer this question, so please forgive me if this is a simple question.

  Quite simply, I am trying to transcode a UDP video stream to a live MP4 stream with ffmpeg.

  I have been unable to successfully implement either step here. Any help or advice is appreciated.
