• Error importing VideoFileClip from moviepy : AttributeError : 'PermissionError' object has no attribute 'message'

  11 mars 2017, par Tahlil

  I’m using jupyter notebook. I have also tried from anaconda console as well.

  Tried importing with both the ways shown below

  from moviepy.editor import VideoFileClip
  
  
  
  from moviepy.video.io.VideoFileClip import VideoFileClip

  Both of them gave me same error. Full trace is below

  I’m running 64 bit version of Windows 10.

  I can’t find any solution anywhere and its driving me crazy ! Seems like its not finding the ffmpeg binary but I have put it in C :\ffmpeg\bin and added this to path environment variable. Followed the instruction from here.

• ffmpeg : "Error setting profile" ; how to keep original resolution odf odd sized videos ; getting Quicktime compatible output ; fixing pixel format

  26 février 2017, par P. Reid

  I’ve been having trouble using ffmpeg to compress videos to something readable by quicktime. My goal in the end is to have a simple command that I can use to compress high bitrate videos (ie screencaptures) to something more reasonable to be able to share them with people.

  I want to use a command I found here as a starting point :

  ffmpeg -i input-file.avi -codec:v libx264 -profile: high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -codec:a libfdk_aac -b:a 128k output_file.mp4

  Unfortunately I get this error :

  [libx264 @ 0x7f92ab81c200] Error setting profile high.
  
  [libx264 @ 0x7f92ab81c200] Possible profiles: baseline main high high10 high422 high444
  
  Stream mapping:
  
    Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264))
  
  Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  If I take out the -profile: high the command functions but the output still doesn’t open in quicktime (it does in VLC). I can’t find the keyword -profile on the ffmpeg man page : https://ffmpeg.org/ffmpeg.html so I don’t know if this is important or what to do about it.

  Does anyone know what might be causing my problem ? What should I do to try and debug this problem ? I would describe myself as inexperienced so sorry if I’m missing something obvious.

  Thanks in advance for your help,
  Peter

  This is my ffmpeg version :

• Rematrix is needed between 10 channels and mono but there is not enough information to do it

  8 octobre 2017, par siriele

  I’ve been fighting for a number of days now trying to get FFmpeg working with combining several audio files at specific times into one file. So my idea was to generate silence up to the time i want to play a sound.Then merge the audio together with a filter. The below code works when I have five or less files, but seems to fall apart.
