  • FFmpeg : encoding a PCM audio file to AAC using AAC codec info from another file

    7 septembre 2022, par Siddharth Kumar

    I have two audio files :

    


      

    1. audio_0.wav : PCM audio

      2. 


    2. audio_1.aac : encoded audio using some parameters

      3. 


    


    I'm trying to achieve the following outcome with FFmpeg :

    


    Create a new file audio_2.aac which contains audio from audio_0.wav encoded using the codec parameters from audio_1.aac.

    


    If I run the following :
ffmpeg -i audio_0.wav -i audio_1.aac -c copy audio_2.aac then I get streams from both muxed together.
I do not want content from audio1.aac. Any pointers to solve this would be appreciated.

    


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

    2 août 2022, par 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 ?

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

    5 mars 2016, par 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 &amp;&amp; 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.
