  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • 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 :

  • script doesnt recognize bars / lenght right for cutting audio , ffmpeg terminal

    14 avril 2024, par totzillarbeats

    This Terminal script doesnt recognize bars / lenght right for cutting audio , maybe somebody knows whats 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

    # 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] ..."

    else

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