Que fait exactement ce script ?
18 janvier 2011, parCe script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
Installation de dépendances de MediaSPIP
Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :

Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Concatenating video using FFMPEG wrapper class [duplicate]
21 décembre 2017, par alan samuelThis question already has an answer here :
I am trying to concatenate video using NReco.VideoConverter wrapper class made for FFMPEG.
I have three video files with the same frame rate and same frame size.
Here is what I have done.
string toconcatfile = @"C:\Users\Alan\Desktop\Black.mp4";
string output1 = @"C:\Users\Alan\Desktop\output1.mp4";
string output2 = @"C:\Users\Alan\Desktop\output2.mp4";
string finaloutput = @"C:\Users\Alan\Desktop\finaloutput.mp4";All the three videos have a frame rate of 25 and Video frame size yet it fails when I add in toconcatfile to the final conversion method.
It works when its just output1 and output2 meaning there must be a different setting in toconcatfile.
Here is what I have tried.
FFMpegConverter fFMpeg = new FFMpegConverter();
//Slices first video
ConvertSettings settings = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
MaxDuration = startcut,
AudioSampleRate = 44100
};
//Slices second video
ConvertSettings settings2 = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
Seek = endcut,
AudioSampleRate = 44100
};
//Copies framerate and size from the previous video to the concatenation video
ConvertSettings settings3 = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
MaxDuration = 4,
AppendSilentAudioStream = true,
AudioSampleRate = 44100
};
string newblack = @"C:\Users\Alan\Desktop\newblack.mp4";
//Slice method called
fFMpeg.ConvertMedia(pathtofile, Format.mp4, output1, Format.mp4, settings);
fFMpeg.ConvertMedia(pathtofile, Format.mp4, output2, Format.mp4, settings2);
fFMpeg.ConvertMedia(toconcatfile, Format.mp4, newblack, Format.mp4, settings3);
String[] inputfiles = new String[2];
inputfiles[0] = output1;
inputfiles[1] = newblack;
//inputfiles[1] = output2;
ConcatSettings concatSettings = new ConcatSettings
{
//CustomOutputArgs = output1+" "+ toconcatfile+ " "+output2+ " -filter_complex \"[0:v:0][0:a:0][1:v:0][1:a:0][2:v:0][2:a:0]concat=n=3:v=1:a=1[outv][outa]\" -map \"[outv]\" - map \"[outa]\""
};
fFMpeg.ConcatMedia(inputfiles, finaloutput, Format.mp4, concatSettings);Can anyone help ?

c++ - using FFmpeg encode and UDP with a Webcam
14 mars, par RendresI'm trying to get frames from a Webcam using OpenCV, encode them with FFmpeg and send them using UDP.



I did before a similar project that instead of sending the packets with UDP, it saved them in a video file.

The code compiles but it returns Segmentation fault in the function av_interleaved_write_frame(). I've tried several implementations or several codecs (in this case I'm using libopenh264, but using mpeg2video returns the same segmentation fault). I tried also with av_write_frame() but it returns the same error.



As I told before, I only want to grab frames from a webcam connected via USB, encode them to H264 and send the packets through UDP to another PC.



My console log when I run the executable is.

As you can see, FFmpeg uses libopenh264 and configures it correctly. However, no matter what. It always returns the same Segmentation fault error...



I've used commands like this.



ffmpeg -s 640x480 -f video4linux2 -i /dev/video0 -r 30 -vcodec libopenh264 -an -f h264 udp://127.0.0.1:8080



And it works perfectly, but I need to process the frames before sending them. Thats why I'm trying to use the libs.



My FFmpeg version is.

I tried to get more information of the error using gbd, but it didn't give me debugging info.



How can I solve this problem ? I don't know what else can I try...



Thank you !

ffmpeg version 2.6.8 : Stream specifier ':a' in filtergraph description matches no streams
16 décembre 2020, par AshitakaI am not getting why this isn't working.. I have tried to get the video streams with [0:v]/[0:1]/[0:v:0] & the audio streams with [0:a]/[0:0]/[0:0:0].
nothing worked.


Explaining the inputs :


1.1st input stream is a video that can be of varying resolution on which the filter adds a padding on to make it 600:480.


2.2nd input is an overlay png which is already at 5:4 ratio.. just making it 600:480 before it gets overlaid in the filter.


3.3rd & 4th ones are also videos which I don't care if they get stretched.. n they are getting stretched to 600:480.


4.so finally there are 3 streams 1 overlaid video 2 stretched videos which needs to be concatenated.


here's the command :


ffmpeg 
-i '/home/vidinflux/public_html/assets/temp/2018020116464612/2018020116464612.mp4' 
-i '/home/vidinflux/public_html/assets/temp/2018020116464612/2018020116464612_overlay.png'
