  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Ubuntu 14 FFMPEG & Black and White Conversion

    3 septembre 2015, par Jesse James Richard

    As the HUE option doesn’t exist in FFMPEG on Ubuntu because it’s AVCONC, can it just be assumed that it’s nearly impossible to convert a video to black and white since FFMPEG is effectively incomplete ?

  • Converting png images series to webm with transparent white background from Daz3d

    25 août 2015, par James

    I’m trying to make a webm video with a transparent background from a Daz3D model.
    My process is export png image series with transparent background from Daz3D, use ffmpeg to convert png series to webm video.
    This was working well in Daz3D 4.6.

    But in Daz3D 4.8 the exported background is black instead of white, so when converted to webm is ok on Chrome as has the transparency, but on Firefox is black and has a halo (as Firefox does not support transparency so displays background).

    So I’m looking for a solution with Daz3D, or tools like ImageMagik.
    I almost got it with ImageMagik,

    convert -alpha extract *.png mask.png
    
mogrify -flatten talk*.png
    
for /f %x in ('dir /s /b blink*.png') do @composite -compose CopyOpacity mask-0.png %x %x

    But for some reason the final webm has a white background not transparent ...
    Some more info here,

    Doh, okay I figured it out. My images were good, but I somehow have two different versions of ffmpeg on my computer and was using the wrong one that doesn’t seem to support transparency.

    Now it is working.

    My only issue is the last shell line,

    for /f %x in (’dir /s /b blink*.png’) do @composite -compose CopyOpacity mask-0.png %x %x

    This only uses mask-0.png, instead of mask-1 for blink01.png, mask-2 for blink02.png etc.
