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 (...) -

Was able to mix two audio files and 1 video, but the audio is not in sync with the video
15 janvier 2019, par SumeetI am trying to mix 2 audio files, say audio1.mp3 and audio2.wav with a video file, say video.mp4. I was able to mix the files into one file, say final.mp4, but the audio and video in the final file is not in sync.
I used amix to mix the files using command prompt.
I am not able to figure out how to use apad in my command line to see if that works. Should I really be using apad or am I on the wrong track ?ffmpeg -i video.mp4 -i audio1.mp3 -i audio2.wav -filter_complex "[1][2]amix=inputs=2[a]" -map 0:v -map "[a]" -c:v copy outputfilename.mp4

Android record square video and concat
25 février 2015, par faruk.kuscanIs there a way to record square (640x640) videos and concat them in Android ? I looked up in the Internet and found some solutions. The solution seems to be "ffmpeg". However, to use ffmpeg I need to dive into NDK and build ffmpeg from its sources. Is there a solution by only using the Android SDK ?
My basic needs are :
- Record multiple videos (square format)
- Resize captured videos (i.e. 480x480 to 640x640)
- Concat captured videos
- Rotate final video (clockwise 90)
- Final output will be in mp4 or mpg format

Android FFmpeg cant set quality of image
24 octobre 2017, par TheOtherguyz4kjI am working with FFmpeg on Android, I am trying to extract frames from a video every second. I made this command that works well :
final String cmd[] = {
"-i",
videoPath,
"-vf",
"fps=1",
mediaStorageDir.getAbsolutePath() +
"out%d.png"
};Now I want to reduce the quality of the extracted frames so I tried this but get the error :
final String cmd[] = {
"-i",
videoPath,
"-vf",
"fps=1",
"-qscale:v 12",
mediaStorageDir.getAbsolutePath() +
"out%d.png"
};At least one output file must be specified
What is the problem ? I have searched online a lot and cant find a solution to the problem, also is there a better way to reduce the quality of my extracted frames ?
thanks
