Script d’installation automatique de MediaSPIP

25 avril 2011, par kent1

Afin 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.

Why the video recorded using FFmpeg gives random freezes every few seconds and overall feels laggy too ?

12 avril 2018, par user136266
Why the video recorded using FFmpeg gives random freezes every few seconds and overall feels laggy too (choppy video) ?

The command used is as follows
```
ffmpeg -f avfoundation -video_size 1280x720 -framerate 60 -input_format mjpeg -i "C922" -vcodec libx264 -crf output.mp4
```
In Android how to add text as watermark on already recorded video with ffmpeg ?

23 juillet 2016, par jullie
I am trying to set text as a watermark on already recorded video but it is not working. As I tried image.png as a water mark and it works by following this url http://androidwarzone.blogspot.in/2011/12/ffmpeg4android.html

Command for apply image as watermark on already recorded video :
```
String[] complexCommand = {"ffmpeg","-y" ,"-i", videoPathHere,"-strict",

"experimental", "-vf", "movie=" 

+ Environment.getExternalStorageDirectory().getAbsolutePath() 

+ "/watermarkImg.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]",

"-s", "160x120","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000", 

"-ac", "2", "-ar", "22050", 

Environment.getExternalStorageDirectory().getAbsolutePath()+"/watermark.mp4"}; 
```
but when I tried to implement text as watermark its not working :
```
String[] complexCommand = {"ffmpeg", "-y" , "-i", videoPathHere, "-strict", "experimental", 

"-vf", "drawtext=fontfile=" + file + ":text=TestText", "-s", "160x120", "-r", "30", 

"-b", "15496k", "-vcodec", "mpeg4", "-ab", "48000", "-ac", "2", "-ar", "22050", 

Environment.getExternalStorageDirectory().getAbsolutePath()+"/watermark.mp4"}; 
```
Even I tried this also
http://video.stackexchange.com/questions/15551/ffmpeg-drawtext-filter-create-transparent-background-with-text

but it is also not working in my case.

So, what is going wrong with adding text as watermark ?

I make changes in commenad from ;text=TestText to :text=TestText then it shows given error.

The fact is that when recording video no lags(freezes) are not noticeable. After recording the video, when you look carefully, the lags are noticeable, and if you move the phone quickly when recording, then after the recording you can see the freezes, as if you have glued several GIFs.

I tried everything I could : the frame rate changed for 30, 60, 100. I changed the Video quality, pixelFormat (although I do not know why) and many things that

I did not understand. But still no use. Maybe there is someone who understands. Tell me how to correct these distortions(freezes) ?
