Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -
Publier sur MédiaSpip
13 juin 2013Puis-je poster des contenus à partir d’une tablette Ipad ?
Oui, si votre Médiaspip installé est à la version 0.2 ou supérieure. Contacter au besoin l’administrateur de votre MédiaSpip pour le savoir -
Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

Error Opening RTMP Stream through FFmpeg command when executed through exec package [closed]
3 octobre 2024, par AkhilI have been trying to transcode the live stream from RTMP server running on
rtmp://localhost:1936/live/testwith FFmpeg in a Go application usingos/execpackage, But seems to not work and gives the input/output error (I have attached below). The same exact ffmpeg command when I execute on terminal, works as its supposed to. Not Sure why that is, here is my code for reproducing and analyzing the mistakes.

ffmpegCmd := fmt.Sprintf("ffmpeg -nostdin -i rtmp://localhost:1936/live/%s -c:v libx264 -s %s -f %s %s/stream.mpd",
 streamKey, resolution, sp.OutputFormat, outputPath)
 log.Printf("Executing FFmpeg command: %s", ffmpegCmd)

 // Prepare the command execution with a timeout context
 ctx, cancel := context.WithTimeout(context.Background(), 60*time.Second) // Set a 60-second timeout
 defer cancel()

 cmd := exec.CommandContext(ctx, "bash", "-c", ffmpegCmd)


the ffmpeg command looks like this :

ffmpeg -nostdin -i rtmp://localhost:1936/live/test -c:v libx264 -s 1920x1080 -f dash output/test/1080p/stream.mpd

I get the following error :


Error opening input: Input/output error

Error opening input file rtmp://localhost:1936/live/test.

Error opening input files: Input/output error

Exiting normally, received signal 2.

signal: interrupt


I have already tried to break the command, and then execute it. Something like :


cmd := exec.CommandContext(ctx,
 "ffmpeg",
 "-nostdin",
 "-i", "rtmp://localhost:1936/live/"+streamKey,
 "-c:v", "libx264",
 "-s", resolution,
 "-f", sp.OutputFormat,
 outputPath+"/stream.mpd")


After running the ffmpeg command with -loglevel debug and -report :


Here is the logs and errors I get :


When I run it within the go application :

FFMPEG is not working in app service post deployment
1er mars 2024, par Tushar GuptaI using the Xabe.FFmpeg package to generate clips from a video. The code is basically converting a video to multiple clips and it's working fine in my local but whenever I am uploading the code to app service the code is not working.

Screen recording with ffmpeg has stuttering [closed]
7 novembre 2024, par Adam LabušI am recording with ffmpeg like so :
ffmpeg -f x11grab -probesize 18M -framerate 30 -video_size 1920x1080 -i :0.0+0,0 -f pulse -i -c:v libx264 -preset ultrafast -c:a aac .mkv

Problem :


Usually at the start the video starts to stutter, sometimes stuttering up to 20 seconds, each frame during this stuttering is shown for 1-5 seconds. Example video : https://drive.google.com/file/d/1uwdaFboCO2qNALgaPC8JD15W64BE3VyY/view?usp=sharing

Memory: 884.62 MiB / 15.49 GiB (6%)
Swap: 0 B / 8.00 GiB (0%)
Disk (/): 5.45 GiB / 14.94 GiB (37%) - xfs


My gpu(20%), cpu (50%), disk utilisation is always in well perfect range - I tried stress testing gpu, ram, cpu and disk while recording and it had no effect on the recording. I tried recording to ramdisk. I always have 10gb ram available. I ran the same command on my laptop (hp 850 g5) and computer and encountered no stuttering at all.


If it matters the machine is running bare Xorg and openbox display manager


I have tried :


- 

- setting fps_mode to cfr - because the frame rate does fluctuate around 29-30 at the start
- setting fps_mode to vfr
- setting fps_mode to passthrough
- setting cfr all the way to 40
- presets veryfast, faster
- increasing thread_queue_size
- async=1
