  • 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 && 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.

  • Google Speech API returns empty result for some FLAC files, and not for the others although they have same codec and sample rate

    15 mars 2021, par Chad

    Below code is what I used to make request for transcription.

    


    import io
from google.cloud import speech_v1p1beta1 as speech
def transcribe_file(speech_file):
    """Transcribe the given audio file."""

    client = speech.SpeechClient()

    encoding = speech.RecognitionConfig.AudioEncoding.FLAC
    if os.path.splitext(speech_file)[1] == ".wav":
        encoding = speech.RecognitionConfig.AudioEncoding.LINEAR16
    with io.open(speech_file, "rb") as audio_file:
        content = audio_file.read()

    audio = speech.RecognitionAudio(content=content)
    config = speech.RecognitionConfig(
        encoding=speech.RecognitionConfig.AudioEncoding.FLAC,
        sample_rate_hertz=32000,
        language_code="ja-JP",
        max_alternatives=3,
        enable_word_time_offsets=True,
        enable_automatic_punctuation=True,
        enable_word_confidence=True,
    )

    response = client.recognize(config=config, audio=audio)
    #print(speech_file, "Recognition Done")
    return response


    


    As I wrote in title, the results of response has empty list for some files, and not for some files.
They have same sample rate and codec(32000, FLAC)

    


    Below is the result of ffprobe -i "AUDIOFILE" -show_streams for one of each cases.

    


    Left one is empty one. The only difference is duration of file.

    


    How can I get non empty results ?

    


    Result of ffprobe

    


    Edit :

    


    Result of ffprobe show stream show format

    


    Something not captured in one screen

    


    Sadly, re-mux didn't work.

    


    I used ffmpeg-git-20210225

  • #include file from library returns "file not found"

    16 juin 2015, par Yossi Tsafar

    I’m getting this error from multiple .a files

    'libavcodec/avcodec.h' file not found

    Even though I added the library to project and also to "Library Search Paths" :

    $(PROJECT_DIR)/Project/Custom/RTPlayer/3rd-party/ffmpeg/lib

    This is how I add it to project :

    #include "libavcodec/avcodec.h"

    Please someone help me what seems to be the problem ?

    Thanks in advance !
