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. -

FFMPEG not working from Python subprocess.Popen but works from command line
21 novembre 2017, par Stuart ClarkeI’m trying to run a
FFMPEGscript from withinpython 3.5.2. theFFMPEGcommand runs fine from the command line but fails within the python script.The function I use to execute the
FFMPEGcommand isdef ffmpeg(args):
err = None
command = [
ffmpegcmd, '-y',
'-loglevel', loglevel
] + args
print("\n\n\n")
print(command)
print("\n\n\n")
print(" ".join(command))
ffmpeg = subprocess.Popen(command, stderr=subprocess.PIPE ,stdout=subprocess.PIPE, universal_newlines=True)
while err == None:
out, err = ffmpeg.communicate()
time.sleep(1)
if err and loglevel=='fatal':
print(" ".join(command))
raise Exception(err)
print(err)The value for args is :
['-i', '/var/www/temp/film.mp4', '-vf', 'scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black', '/var/www/temp/videoHD.mp4']such that the resultant command being passed to
subprocess.Popenis :['ffmpeg', '-y', '-loglevel', 'verbose', '-i', '/var/www/temp/film.mp4', '-vf', 'scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black', '/var/www/temp/videoHD.mp4']The value of loglevel is
verboseonly for troubleshooting but is intended to run asfatal. There are also someprintcommands only in place for troubleshooting.The reason for wanting to increase the resolution is so that it can be combined later with higher resolution videos.

Edit
It was suggested that I use a new function to do much the same thing. So I added the following function and used it for the command that I’m having trouble with :
def ffmpegPro(args):
err = None
for i, arg in enumerate(args):
if(" " in arg or "(" in arg or "[" in arg):
args[i] = "\"" + arg + "\""
command = [
ffmpegcmd, '-y',
'-loglevel', loglevel
] + args
commandStr = " ".join(command)
print("\n\n\n")
print(command)
print("\n\n\n")
print(commandStr)
ffmpeg = subprocess.Popen(commandStr, stderr=subprocess.PIPE, stdout=subprocess.PIPE, universal_newlines=True, shell=True)
while err == None:
out, err = ffmpeg.communicate()
time.sleep(1)
if ffmpeg.returncode == 0 and all([os.path.exists(f) for f in (videoStorage['data_small'], videoStorage['data_big'])]):
print("Job done.")
else:
print("ERROR")
print(err)The resulting command can now be used in
pythonor at the command line without needing to be changed at all. The command is :ffmpeg -y -loglevel verbose -i /var/www/temp/film.mp4 -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black" /var/www/temp/videoHD.mp4The result when executed in

Evolution #2250 : Un bouton pour envoyer les identifiants

An FFMpeg function on azure is not handling simultaneous calls (more than 5)
9 novembre 2017, par The LemonI created a c# httptrigger function on azure which uses FFMpeg to add subtitles to a video, and then just output the video locally (nothing fancy, all the files are in the local resources for the function, and the output is there as well). The process runs perfectly fine when I test it, I made a C# app to call the function and when I test the app it works fine as well. The only problem is when I tell the app to call the function several times at once it will only work for three or four simultaneous calls, any more than that will cause all of the calls to fail.
Below is included the function code, the C# app code, and the partial output for successful calls and for failed calls. Any help or advice would be greatly appreciated as always. Regards Cuannote - the ffmpeg output from the azure function is largely omitted, as it produces output every few frames. I’ve included the start and the end of the output
This is the C# method which is being run multiple times at once.
public static async void callHTTP(string url, int num)
{
using (var client = new HttpClient())
{
client.Timeout = TimeSpan.FromMinutes(10);
var content = new StringContent(JsonConvert.SerializeObject(" {\"name\": \"Azure\"}"), Encoding.UTF8, "application/json");
System.TimeSpan tmp = DateTime.Now - time1;
Console.WriteLine("Process {0} has started after time {1}", num + 1, tmp.ToString());
var response = await client.PostAsync(url, content);
tmp = DateTime.Now - time1;
Console.WriteLine("Process {0} has finished after time {1}", num + 1, tmp.ToString());
if (response.IsSuccessStatusCode)
{
Console.WriteLine("this is a reply");
finished += 1;
tmp = DateTime.Now - time1;
Console.WriteLine("Runningtime for process {0} was {1}", num + 1, tmp.ToString());
}
}
}This is the function being called
