  • Install ffmpeg in to virtual environment

    22 mars, par ldg

    I am trying to install ffmpeg in order to use it on OpenAI to record videos. I have installed it using brew install ffmpeg but somehow when I compile my code I get the same error, it is like the package is not recognized by my virtualenv where I am working.

    Error on Python console:

    raise error.DependencyNotInstalled("""Found neither the ffmpeg nor avconv executables. On OS X, you can install ffmpeg via `brew install ffmpeg`. On most Ubuntu variants, `sudo apt-get install ffmpeg` should do it. On Ubuntu 14.04, however, you'll need to install avconv with `sudo apt-get install libav-tools`.""")

    However, when I execute which ffmpeg I got the following path /usr/local/bin/ffmpeg.

    It seems like that Anaconda for example needs a specific command to install this package into its environment, it is the same for virtualenv?

    Thanks in advance.

  • Alexa developer console gives me "The audio is not of a supported MPEG version" Error

    20 mars, par Boban BoBo Banjevic

    I am trying to make an Alexa skill, and I am using audio mp3 files stored is S3, lambda function has access to my DynamoDb and ultimately S3. But I have an issue with my audio files. I keep on getting "The audio is not of a supported MPEG version" when I test alexa skill. I tried multiple ffmpeg -i file conversions.

    When I type ffprobe -v quiet -print_format json -show_format -show_streams "Piano.mf.A1.audio10.mp3" this is what i have for my file down below:

    
Input #0, mp3, from 'Piano.mf.A1.audio10.mp3':

    encoder         : Lavf61.9.107

}

    It should be everything that is required, am I doing something wrong, this is the only thing stopping me from finishing the skill. Asking ChatGPT said it could be because of the mp3float, and after many conversions it still doesn't work.

  • FFMPEG : preset not found in Windows Vista

    18 mars, par StackOverflowNewbie

    I download FFMPEG from http://www.videohelp.com/tools/ffmpeg#download and saved it in my c:\program files\ffmpeg (Windows Vista). My Path's first 2 entries are:

    c:\program files\ffmpeg\bin;c:\program files\ffmpeg\presets;

    I found the following command on the net (http://paulrouget.com/e/converttohtml5video/)

    ffmpeg -i input.avi -acodec libvorbis -ab 96k -vcodec libx264 -vpre main -level 21 -refs 2 -b 345k -bt 345k -threads 0 -s 320x240 output.mp4

    When I run this on command line, I get the following error:

    File for preset main not found

    Any ideas what might be wrong?
