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. -

Revision 74f98e6f45 : Tune rate-distortion modeling to account for frame light change When the varian
7 mai 2014, par Jingning HanChanged Paths :
Modify /vp9/encoder/vp9_pickmode.c
Tune rate-distortion modeling to account for frame light changeWhen the variance is far less than sse, the block is considered to
be under light change. All the energy is compacted into DC coeff
and can be coded at low cost. In such situation, switch the rate-
distortion modeling from sse+var based back to variance based.Note that this is a temporary solution to handle the rare situations
where the scene light changes.Change-Id : I1ee0fe2b9eda6b5fac40152e1841bf23f4d229fd

ffmpeg masks more than one overlay, how can I mask only one ?
6 juin 2020, par Jonathan Winger-LangI am trying to use an alpha mask to mask the corners of a video, it works. But then I try to add another image on top of them and it is also masked.



How can I mask only the one video, not subsequent layers ?






Here you can see that the phone frame is also masked, since it does not goo beyond the (x-axis) edges of the phone.



My script :



ffmpeg -i input.mp4 \
 -loop 1 -i mask.png \
 -i background.png \
 -loop 1 -i frame2.png \
-filter_complex \
 "[0][1] alphamerge [masked_video]; \
 [masked_video][3] overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2 [phone]; \
 [phone] scale=(iw*0.5):(ih*0.5) [scaled_phone]; \
 [2][scaled_phone] overlay=100:100" \
-shortest out.mp4




Thank you
