  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

  • How to overlay an input over an image using ffmpeg ?

    9 mai 2012, par Jona

    I'm looking to create a video using a set of png images that have transparency merged with a static background.

    After doing a lot of digging I seems like it's definitely possible by using the filters library.

    My initial video making without including the background is :

    ffmpeg -y -qscale 1 -r 1 -b 9600 -loop -i bg.png -i frame_%d.png -s hd720 testvid.mp4

    Using -vf I can apply the background as overlay :

    ffmpeg -y -qscale 1 -r 1 -b 9600 -i frame_%d.png -vf "movie=bg.png [wm];[in][wm] overlay=0:0 [out]" -s hd720 testvid.mp4

    However the problem is it's overlaying the background over the input. According libacfilter I can split the input and play with it's content. I'm wondering if I can somehow change the overlay order ?

    Any help greatly appreciated !

    UPDATE 1 :
    I'm trying to make the following filter work but I'm getting the movie without the background :

    ffmpeg -y -qscale 1 -r 1 -b 9600 -i frame_%d.png -vf "movie=bg.png [bg]; [in] split [T1], fifo, [bg] overlay=0:0, [T2] overlay=0:0 [out]; [T1] fifo [T2]" -s hd720 testvid.mp4

    UPDATE 2 :
    Got video making using -vf option. Just piped the input slit it applied image over it and overlayed the two split feeds ! Probably not the most efficient way... but it worked !

    ffmpeg -y -r 1 -b 9600 -i frame_%d.png -vf "movie=bg.png, scale=1280:720:0:0 [bg]; [in] format=rgb32, split [T1], fifo, [bg] overlay=0:0, [T2] overlay=0:0 [out]; [T1] fifo [T2]" -s hd720 testvid.mp4
