  • Les tâches Cron régulières de la ferme

    1 December 2010, by

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Error with LocalAudioFile(file) returns OSError: [Errno 2] No such file or directory

    5 March 2016, by beriukay

    Much like the question here http://developer.echonest.com/forums/thread/3843#reply, I am having the following error:

    File
    "/usr/local/lib/python2.7/dist-packages/echonest/remix/audio.py", line
    944, in init
    sampleRate=sampleRate, numChannels=numChannels) File "/usr/local/lib/python2.7/dist-packages/echonest/remix/audio.py", line
    403, in init
    self.load() File "/usr/local/lib/python2.7/dist-packages/echonest/remix/audio.py", line
    421, in load
    numChannels=self.numChannels, sampleRate=self.sampleRate, verbose=self.verbose) File
    "/usr/local/lib/python2.7/dist-packages/echonest/remix/support/ffmpeg.py",
    line 91, in ffmpeg
    close_fds=(not win) File "/usr/lib/python2.7/subprocess.py", line 710, in init
    errread, errwrite) File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception OSError: [Errno 2] No such file or directory

    I checked input and output file permissions, made sure that both files and all related file paths existed, and that I have all the relevant python tools installed. The first clue is that Subprocess.py is having trouble. Looking at ffmpeg.py on line 88, I started playing around with the Popen function call to see how and why it was misbehaving.

    Solution:

    After messing around with the ffmpeg.py file, I piped the input to the shell (shell=True instead of shell=False), which raised the following error:

    check raise Run timeError(ffmpeg_install_instructions) RuntimeError: en-ffmpeg not found! Please make sure ffmpeg is installed and create a link as follows: sudo ln -s which ffmpeg /usr/local/bin/en-ffmpeg Alternatively, import echonest.remix.support.ffmpeg and modify ffmpeg.FFMPEG to name the appropriate binary.

    So, to finalize the solution, you need to get the binary from https://ffmpeg.org/download.html#build-linux, which in Ubuntu 14.04 means you just need to:

    sudo add-apt-repository ppa:mc3man/trusty-media
    
sudo apt-get update && sudo apt-get upgrade
    
sudo apt-get install ffmpeg
    
sudo ln -s `which ffmpeg` /usr/local/bin/en-ffmpeg

    That should clear this problem right up.

  • FFmpeg output video file much smaller than uncompressed input audio file, using option to preserve original audio quality

    17 March 2021, by Jan

    I attempt to create a video slideshow from a number of image files and an audio file in 2 steps:

    


      

    1. Create a temporary video file from a sequence of image files

      2. 


    2. Add an audio file to the temporary video file with a delay of 5 seconds

      3. 


    


    The audio file is an uncompressed stereo wav file, encoded with a sample rate of 44100 Hz and a bit depth of 32 bits, with a size of 40.1 MB. To preserve the lossless quality of the input audio file I use the option -c:a aac -b:a 192k as per Slideshow Wiki. However, the final output video file has a size of only 4.49 MB.

    


    How can the output video file be about 10 times smaller than the input audio file and still preserve the original lossless quality?

    


    My code:

    


    ffmpeg -f concat -i slide-sequence.txt -c:v libx264 -r 30 -filter_complex format=yuv420p temp.mp4
ffmpeg -i temp.mp4 -i audio.wav -af "adelay=5000|5000" -c:v copy -c:a aac -b:a 192k out.mp4


    


  • File contains data in an unknown format. (m4a load from librosa)

    2 August 2022, by Moriyama Aiko

    So I am currently working on a DNN that takes in m4a files. I have ffmpeg, it creates a few batches and then dies on this error:

    &#xA;

    I am using this command

    &#xA;

        wav, sr = librosa.load(path, sr=16000)&#xA;

    &#xA;

    is it just a broken file? How do I skip such then? Or is it something about loading a m4a file even with ffmpeg and the desired output when tested on a single m4a file?
