    Le lecteur ne fonctionne pas sur Internet Explorer
    Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
    Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...)

  • Making Image Slideshows from Linux Graphic Tools [on hold]

    24 octobre 2019, par Volomike

    How do I make image slideshows as a video file via 4 small jpegs (128px x 128px) and Linux command-line graphic tools ? I need to vary the slideshow transitions with :

    • fade to/from black
    • slide left/right while fading to next image

    If you’re curious, we plan to make videos we can put into mobile phones for real estate listings. (We already have the technology to convert Ogg Theora into proprietary mobile formats.)

  • Encapsulate onvif metadata into avframe

    15 avril 2020, par user8957959

    I have a onvif camera that provides video and metadata via rtsp. I would 
like to create a filter or whatever else that takes the metadata, reads 
them and finally merge into the output video.

    



    I think of something like 
encapsulate them in the alpha channel, in order to keep the video 
viable. I have problem with the first part, because I cannot find a 
filter that manipulates Data (AVMEDIA_TYPE_DATA) to start with. My plan 
is to create a filter that takes data and produce fake avframe with 
metadata, that will be merged with the real video by a filter like 
overlay or everything else. Did someone have some hints for me ?

    aacenc_pred : rework the way prediction is done

    This commit completely alters the algorithm of prediction.
    
The original commit which introduced prediction was completely
    
incorrect to even remotely care about what the actual coefficients
    
contain or whether any options were enabled. Not my actual fault.
    

    This commit treats prediction the way the decoder does and expects
    
to do : like lossy encryption. Everything related to prediction now
    
happens at the very end but just before quantization and encoding
    
of coefficients. On the decoder side, prediction happens before
    
anything has had a chance to even access the coefficients.
    

    Also the original implementation had problems because it actually
    
touched the band_type of special bands which already had their
    
scalefactor indices marked and it’s a wonder the asserion wasn’t
    
triggered when transmitting those.
    

    Overall, this now drastically increases audio quality and you should
    
think about enabling it if you don’t plan on playing anything encoded
    
on really old low power ultra-embedded devices since they might not
    
support decoding of prediction or AAC-Main. Though the specifications
    
were written ages ago and as times change so do the FLOPS.
