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 (...) -

ffmpeg convert from H.264 (High 4:2:2 Profile) MOV to H.264 (Baseline Profile) MP4
26 juillet 2022, par froniqHow can I convert a video (MOV) from H.264 (High 4:2:2 Profile) to H.264 (Baseline Profile) MP4 using ffmpeg ?
I would run that mp4 video on android mobile in a VideoView to support as many mobile types as possible.


I can't do that with this command : ffmpeg -i o1.mov -c:v libx264 -profile:v baseline -c:a aac -ar 44100 -ac 2 -b:a 128k out.mp4.


That'd return an error :

how to get precise video bit rate in a .ts file ?
26 juillet 2022, par Wang YilanI often use
ffprobe
to get video bitrates and audio bitrates, but when I usedffprobe

 Stream #0:1[0x101](und): Audio: mp2 ([3][0][0][0] / 0x0003), 44100 Hz, stereo, fltp, 384 kb/s



it seemed that the bitrate is 1423k,but when I used
bitrate viewer
to get this result, it is 952k :


And 1423k-384k=1039k, it cannot match the result of bitrate-viewer, neither.


So my question are :


- 

- what result is the correct result of this .ts file ?
- Can I get this result in batches ? (using terminal commands or others)






many thanks.

ffmpeg - drawtext filter producing file with no streams
24 juillet 2022, par yarricharI am trying to get ffmpeg's drawtext filter working in an AWS lambda. Other operations like concatenating and trimming files works. But drawtext fails for some reason. I run the exact same command on my local machine and it runs fine.


The output is below. The first line shows the parameters passed to ffmpeg.
You can see at the end of the following output that it's only processing 3 frames before exiting.


Any help would be greatly appreciated.
