Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;

video after ffmpeg command conversion is not playing on windows
10 décembre 2015, par Hemant KumarI am stuck at a very weird and complex problem, hoping if anyone know the solution :
I am converting user uploaded video using ffmpeg command on server and it was working fine as well. Today I found that if a video is recorded by a webcam from windows, is playing well in linux as well as on windows where as if user is creating a video by webcam from linux, is playing only on linux (any browser). On window it’s screen either show loading icon or black screen while audio is working fine.
I am using following codec :
['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']
I work on linux and using html5 player on my website. I am converting video in mp4 format.
Input :
ffmpeg -i /<server path="path">/stream_FE2AF05B-E630-1F7B-390B-37325B31B362.flv -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /<server path="path">/testing.mp4

ffmpeg on rasbian to rtmd server - no output
5 mai 2020, par TwoSevenI have set up a nginx-rtmd server on a raspberry pi and am using it to output to obs. I can successfully stream from my GoPro 7 and pick up the output on VLC on my phone.



I have set up a pi camera on another rpi and using raspivd I can see the camera video in a window on a small touch display attached to it.



I have set up ffmpeg with h264/aac support and piped the output of raspivid into it. Apart from a warning saying cur_dts is invalid, ffmpeg appears to be running (the output says 100k frames so far).



The issue is that I get no output in VLC (just a spinning icon) when I try and connect to the nginx-rtmp server. I do still get the video window on the rpi screen (which is unexpected).



The command I am using is



raspivid -o - -t 0 -w 1920 -h 1080 -fps 25 -b 4000000 -g 50 | ./ffmpeg -loglevel debug -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 128k -g 50 -strict experimental -f flv rtmp://<address>/<app>/<fname>
</fname></app></address>



does anyone have any pointers as to what might be incorrect. I am not so familiar with ffmpeg other than a cursory understanding of the parameters and what it does.



Regards.
