Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Speed of the x265 and ffmpeg HEVC based encoding
10 mai 2015, par userDtrmI’m trying to perform a real-time encoding of a video using HEVC with ffmpeg. I’m able to achieve the required performance when running the x265 encoder separately without the support of ffmpeg. This way the my system can perform the encoding at 30 frames per second. However, my requirement is to create a MPEG-TS stream with the encoded content and therefore, the video is encoded with the ffmpeg as follows :
ffmpeg -s:v 1280x720 -i input.yuv -c:v libx265 -x265-params crf=20:keyint=25:fps=25:preset=ultrafast -f mpegts out.ts
Strangely, the performance of the encoding is reduced drastically and I’m only able to achieve an encoding performance of just 10 frames per second.
Is this a problem of the multiplexing process within ffmpeg ?. Could someone please help me to resolve this issue.
Thanks.

FFMPEG command for video based on ratio [duplicate]
21 novembre 2017, par pocekThis question already has an answer here :
I am using ffmpeg (in linux server with php)
and I want to watermark a
png
logo on themp4
file, my problem is thatI want to scale my
logo
and change it based on source video size(for example 1/4 of height),I have this code bellow :
shell_exec('ffmpeg -i file.mp4 -i logo.png -filter_complex "overlay=10:10" file-watered.mp4");
it works on every video.
For Normal (medium) size image :
For Small (medium) size image (which is bad !)
Ideal output for this size would be :
I’ve changed a little bit my first code like this :
shell_exec('ffmpeg -i file.mp4 -i logo.png -filter_complex "[0:v]scale=500:-1[bg];[bg][1:v]overlay=(main_w-overlay_w):(main_h-overlay_h)" watered.mp4');
The main problem is that, I want to change the logo size based on video size.
How can I do it with ffmpeg ?
