  • Evolution #4827 (Nouveau) : [UX] Regrouper les versions d’un même plugin

    21 juin 2021, par cam.lafit -

    Il arrive qu’on ait plusieurs version d’un même plugin. Entre autre une version dans plugins/ puis au moins une autre dans plugins/auto/
    SVP liste alors toutes les versions du plugin comme si cela était des plugins distincts. Ce serait plus pertinent de les regrouper dans un même bloc et d’éviter de proposer des actions déjà réalisées (comme la mise à jour)

    On pourrait tout regrouper en un seul bloc plugin et proposer les diverses actions disponibles

  • ffmpeg xfade not working well with acrossfade

    7 juin 2021, par Richard

    I'm having trouble using xfade together with acrossfade.

    


    I have two videos t1.mp4 and t2.mp4 of same fps, resolution and so on. Both videos are 15 seconds long.

    


    Now I want a one-second fade transition in between.

    


    Without acrossfade,

    


    ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p" output.mp4


    


    after checking all the frames, the transition looks good. There are some overlapped frames with fading effect.
Please see below two consecutive frames.
fading11fading12

    


    But the second part of the result has no audio, that's why I decide to use acrossfade.

    


    ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p;acrossfade=d=1" output.mp4


    


    Now it seems the transition effect is incomplete, there are less overlapped frames with fading effect, and the transition is sharp. Please see below two consecutive frames, same frame nubmer as above.

    What am I missing here please ?

    


     ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p;acrossfade=d=1" output.mp4
