De l’upload à la vidéo finale [version standalone]
31 janvier 2010, parLe chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
Upload et récupération d’informations de la vidéo source

Can I use the file buffer or stream as input for fluent-ffmpeg ? I am trying to avoid saving the video locally to get its path before removing
22 avril 2023, par Moath ThawahrehI am receiving the file via an api, I was trying to process the file.buffer as input for FFmpeg but it did not work, I had to save the video locally first and then process the path and remove the saved video later on.
I don't want to believe that there is no other way to solve this and I have been looking for solutions and workarounds but it was all about ffmpeg input as a path.


I would love to find a solution using fluent-ffmpeg because it has some other great features, but I won't mind any suggestions for compressing the video using any different approaches if it's more efficient


Again my code below works fine but I have to save the video and then remove it I am hoping for a more efficient solution :


fs.writeFileSync('temp.mp4', file.buffer);

 // Resize the temporary file using ffmpeg
 ffmpeg('temp.mp4') // here I tried pass file.buffer as readable stream,it receives paths only 
 .format('mp4')
 .size('50%')
 .save('resized.mp4')
 .on('end', async () => {
 // Upload the resized file to Firebase
 const resizedFileStream = bucket.file(`video/${uniqueId}`).createWriteStream();
 fs.createReadStream('resized.mp4').pipe(resizedFileStream);

 await new Promise<void>((resolve, reject) => {
 resizedFileStream
 .on('finish', () => {
 // Remove the local files after they have been uploaded
 fs.unlinkSync('temp.mp4');
 fs.unlinkSync('resized.mp4');
 resolve();
 })
 .on('error', reject);
 });

 // Get the URL of the uploaded resized version
 const resizedFile = bucket.file(`video/${uniqueId}`);
 const url = await resizedFile.getSignedUrl({
 action: 'read',
 expires: '03-17-2025', // Change this to a reasonable expiration date
 });

 console.log('Resized file uploaded successfully.');
 })
 .on('error', (err) => {
 console.log('An error occurred: ' + err.message);
 });
</void>

It's possible to catch ffmpeg errors with python ?
4 avril 2019, par Elros RomeoHi I’m trying to make a video converter for django with python, I forked django-ffmpeg module which does almost everything I want, except that doesn’t catch error if conversion failed.
Basically the module passes to the command line interface the ffmpeg command to make the conversion like this :
/usr/bin/ffmpeg -hide_banner -nostats -i %(input_file)s -target
film-dvd %(output_file)Module uses this method to pass the ffmpeg command to cli and get the output :
def _cli(self, cmd, without_output=False):
print 'cli'
if os.name == 'posix':
import commands
return commands.getoutput(cmd)
else:
import subprocess
if without_output:
DEVNULL = open(os.devnull, 'wb')
subprocess.Popen(cmd, stdout=DEVNULL, stderr=DEVNULL)
else:
p = subprocess.Popen(cmd, stdout=subprocess.PIPE)
return p.stdout.read()But for example, I you upload an corrupted video file it only returns the ffmpeg message printed on the cli, but nothing is triggered to know that something failed
This is an ffmpeg sample output when conversion failed :
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x237d500] Format mov,mp4,m4a,3gp,3g2,mj2
detected only with low score of 1, misdetection possible !
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x237d500] moov atom not found
/home/user/PycharmProjects/videotest/media/videos/orig/270f412927f3405aba041265725cdf6b.mp4 :
Invalid data found when processing inputI was wondering if there’s any way to make that an exception and how, so I can handle it easy.
The only option that came to my mind is to search : "Invalid data found when processing input" in the cli output message string but I’m not shure that if this is the best approach. Anyone can help me and guide me with this please.

Doubts in the development of a music bot for discord, using DSharpPlus and ffmpeg
21 avril 2018, par VralagoI have been making a bot for Discord, and recently I thought about adding the music system. Well I even understand how it works but also have some things that I’m not understanding how I should do it (I’m using the DiscordSharpPlus api), for example putting the music on pause (bearing in mind that ffmpeg continues to read the music).
So I wanted to know if anyone can explain me or tell me how I should do it or how it works, given that it is my first time using ffmpeg and I do not know all the functions of the program.
If it is necessary, there is the code where the ffmpeg is and the sending of data to the discord.
public static async Task AddMusicFromYoutube(VoiceNextConnection vnc, CommandContext ctx, string url)
{
string fileName = "";
if (url.ToLower().Contains("youtube.com"))
{
fileName = await DownloadFromYouTube(url);
if (fileName == string.Empty) return;
await ctx.RespondAsync($"Playing for **Youtube** -> `{url}`");
await vnc.SendSpeakingAsync(true);
var ffmpeg_pro = new ProcessStartInfo
{
FileName = "Libs/ffmpeg",
Arguments = $@"-xerror -i ""{fileName}.mp3"" -ac 2 -f s16le -ar 48000 pipe:1",
RedirectStandardOutput = true,
UseShellExecute = false
};
var ffmpeg = Process.Start(ffmpeg_pro);
Stream ffout = ffmpeg.StandardOutput.BaseStream;
using (var ms = new MemoryStream())
{
await ffout.CopyToAsync(ms);
ms.Position = 0;
var buff = new byte[3840];
var br = 0;
while ((br = ms.Read(buff, 0, buff.Length)) > 0)
{
if (br < buff.Length)
for (var i = br; i < buff.Length; i++)
buff[i] = 0;
await vnc.SendAsync(buff, 20); // Send PCM date for discord
//tentativa de parar a musica
if (Program.IsPuased)
{
while (Program.IsPuased)
{
}
}
}
ms.Close();
}
await vnc.SendSpeakingAsync(false);
}
else
{
await ctx.RespondAsync($"{ctx.Member.Mention}, por agora só aceito link's do Youtube!");
return;
}
}
