  • 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.

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Script doesnt recognize bars / length right for cutting audio , ffmpeg terminal

    14 avril 2024, par totzillarbeats

    This terminal script doesn't recognize bars / length right for cutting audio, maybe somebody knows what's wrong with the calculation ...

    


    Would be happy about any help the cutting already works !

    


    #!/bin/bash

# Function to extract BPM from filename

get_bpm() {
    local filename="$1"
    local bpm=$(echo "$filename" | grep -oE '[0-9]{1,3}' | head -n1)
    echo "$bpm"
}

# Function to cut audio based on BPM
cut_audio() {
    local input_file="$1"
    local bpm="$2"
    local output_file="${input_file%.*}_cut.${input_file##*.}" # Appends "_cut" to original filename

    # Define the number of beats per bar (assuming 4 beats per bar)
    beats_per_bar=4

    # Calculate the duration of each bar in seconds
    bar_duration=$((60 * beats_per_bar / bpm))

    # Define start and end times for each bar range
    start_times=(0 21 33 45 57 69 81 93 105 117 129 141)
    end_times=(20 29 41 53 65 77 89 101 113 125 137 149)

    # Iterate through each bar range
    for ((i = 0; i < ${#start_times[@]}; i++)); do
        start_time=${start_times[$i]}
        end_time=${end_times[$i]}
        echo "Cutting audio file $input_file at $bpm BPM for bar $((i + 1)) ($start_time-$end_time) for $bar_duration seconds..."

        # Cut audio for current bar range using ffmpeg
        ffmpeg -i "$input_file" -ss "$start_time" -to "$end_time" -c copy "$output_file"_"$((i + 1)).${input_file##*.}" -y
    done

    # Check if the output files are empty and delete them if so
    for output_file in "${output_file}"_*; do
        if [ ! -s "$output_file" ]; then
            echo "Output file $output_file is empty. Deleting..."
            rm "$output_file"
        fi
    done

    echo "Audio cut and saved as $output_file"
}


# Main script
if [ "$#" -eq 0 ]; then
    echo "Usage: $0 [audio_file1] [audio_file2] ..."
    exit 1
fi

for file in "$@"; do
    bpm=$(get_bpm "$file")
    if [ -z "$bpm" ]; then
        echo "Error: No BPM found in filename $file"
    else
        cut_audio "$file" "$bpm"
    fi
done


    


    Maybe its only the math calc in the beginning but idk :)

  • FFmpeg conversion to mp3 works in terminal, not in script

    19 juillet 2013, par user2598172

    I can run

    ffmpeg -i test.m4a -vn -acodec libmp3lame -ab 256k test.mp3

    And it works perfectly. However, when I have the line :

    ./ffmpeg -i "$SONG_SAVE.m4a" -vn -acodec libmp3lame -ab 256k "$SONG_SAVE$EXT" &> /dev/null

    running in a .sh script (downloading the same file that I was able to successfully convert through the terminal), it returns an mp3 file with no audio data. Does anyone have any idea what could be causing this ? Thanks !

    EDIT : here is the whole script :
