Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

C# How do I set the volume of sound bytes[]
23 juillet 2016, par McLucarioIm trying to change the volume of sound bytes[] in C#. Im reading a sound file with FFMPEG and and wanna change the volume on the fly. I found some examples and but I didnt understand them.
public void SendAudio(string pathOrUrl)
{
cancelVid = false;
isPlaying = true;
mProcess = Process.Start(new ProcessStartInfo
{ // FFmpeg requireqs us to spawn a process and hook into its stdout, so we will create a Process
FileName = "ffmpeg",
Arguments = "-i " + (char)34 + pathOrUrl + (char)34 + // Here we provide a list of arguments to feed into FFmpeg. -i means the location of the file/URL it will read from
" -f s16le -ar 48000 -ac 2 pipe:1", // Next, we tell it to output 16-bit 48000Hz PCM, over 2 channels, to stdout.
UseShellExecute = false,
RedirectStandardOutput = true, // Capture the stdout of the process
Verb = "runas"
});
while (!isRunning(mProcess)) { Task.Delay(1000); }
int blockSize = 3840; // The size of bytes to read per frame; 1920 for mono
byte[] buffer = new byte[blockSize];
byte[] gainBuffer = new byte[blockSize];
int byteCount;
while (true && !cancelVid) // Loop forever, so data will always be read
{
byteCount = mProcess.StandardOutput.BaseStream // Access the underlying MemoryStream from the stdout of FFmpeg
.Read(buffer, 0, blockSize); // Read stdout into the buffer
if (byteCount == 0) // FFmpeg did not output anything
break; // Break out of the while(true) loop, since there was nothing to read.
if (cancelVid)
break;
disAudioClient.Send(buffer, 0, byteCount); // Send our data to Discord
}
disAudioClient.Wait(); // Wait for the Voice Client to finish sending data, as ffMPEG may have already finished buffering out a song, and it is unsafe to return now.
isPlaying = false;

Discord.js Music bot "TypeError" when playing audio with dispatcher
21 février 2020, par Cole PerryI’m new to Discord.js and I’m trying to have the bot join a voice channel and play an audio file on my computer. I have been following this guide : https://discord.js.org/#/docs/main/stable/topics/voice . Here is the Index.js page :
Colesbot.on('message', message=>{
if (message.content === '/join') {
// Only try to join the sender's voice channel if they are in one themselves
if (message.member.voiceChannel) {
message.member.voiceChannel.join().then(connection => {
message.reply('I have successfully connected to the channel!');
// To play a file, we need to give an absolute path to it
const dispatcher = connection.playFile('C:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\Assets\Glory.mp3');
dispatcher.on('end', () => {
// The song has finished
console.log('Finished playing!');
});
dispatcher.on('error', e => {
// Catch any errors that may arise
console.log(e);
});
dispatcher.setVolume(0.5); // Set the volume to 50%
}).catch(console.log);
} else {
message.reply('You need to join a voice channel first!');
}
}
});
exports.run = (client, message, args) => {
let user = message.mentions.users.first || message.author;
}FFMPEG is installed and I have set the environment path for it. When I type FFMPEG in the command line I get the proper response.
Some have said I need to install the ffmpeg binaries but when I run npm install ffmpeg-binaries I get an error message that is here
So then I tried installing an older version and I’m now using ffmpeg-binaries@3.2.2-3 but when I type /join I get the error
[ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object
