La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -

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


Diagnostics :


Machine details :


OS: Fedora Linux 41 (Server Edition) x86_64
Host: HP ProDesk 600 G2 DM
Kernel: Linux 6.11.5-300.fc41.x86_64
WM: Openbox (X11)
CPU: Intel(R) Core(TM) i5-6500T (4) @ 3.10 GHz
GPU: Intel HD Graphics 530 @ 1.10 GHz [Integrated]
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

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 :

Correct usage of fdkaac for liquidsoap->icecast
1er février 2024, par user4893295Can't seem to get aac working using
fdkaacwith liquidsoap. It just seems to shutdown.

TBF I have no idea which
aotortransmuxto use for "normal" icecast stuff. mp3 works fine, and the icecast server works fine with aac from other sources (BUTT etc).

This is my starting point from the liquidsoap cookbook :


%fdkaac(channels=2, samplerate=44100, bandwidth="auto", bitrate=64, afterburner=false, aot="mpeg2_he_aac_v2", transmux="adts", sbr_mode=false)


And this is my output from liquidsoap :

EDIT it does seem to be using video, which wouldn't help ? Looking at this bit :

But no idea why or how to stop that...
