  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

    Préambule
    Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
    Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

  • ffmpeg with Axis P1347 returns 400 Bad Request, but Axis 1357 works

    3 mai 2016, par steampowered

    I have two cameras : an Axis P1347 and an Axis P1357. ffmpeg gets a 400 Bad Request on the P1347 but everything works fine with the P1357.

    I am able to successfully stream rtsp video using vlc from an Axis P1347 Camera using the following url :

    rtsp://10.8.3.85:554/axis-media/media.amp?videocodec=h264&audio=1

    However, this same url in ffmpeg gives the following for the Axis P1347 Camera :

    root@ubuntu4-virtual-machine:/home/ubuntu4# ffmpeg -re -v verbose  -i "rtsp://10.8.3.85:554/axis-media/media.amp?videocodec=h264&audio=1"

    The same ffmpeg command works great with the nearly identical Axis P1357 Camera :

    root@ubuntu4-virtual-machine:/home/ubuntu4# ffmpeg -re -rtsp_transport tcp -i "rtsp://10.8.3.90:554/axis-media/media.amp?videocodec=h264&audio=1"

       Stream #0:1: Audio: aac (LC), 16000 Hz, mono, fltp

    Obviously rtsp is turned on and working if vlc can display video, correct ? So why does VLC work with the camera, but not ffmpeg ? Note ffmpeg is installed and works correctly with a similar camera.

  • #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 !

  • 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 show stream show format

    Sadly, re-mux didn't work.
