  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • avcodec/cuviddec : Add support for decoding HEVC 4:4:4 content

    7 octobre 2018, par Philip Langdale
    avcodec/cuviddec : Add support for decoding HEVC 4:4:4 content

    This is the equivalent change for cuviddec after the previous change
    
for nvdec. I made similar changes to the copying routines to handle
    
pixel formats in a more generic way.
    

    Note that unlike with nvdec, there is no confusion about the ability
    
of a codec to output 444 formats. This is because the cuvid parser is
    
used, meaning that 444 JPEG content is still indicated as using a 420
    
output format.

  • Sox mute white noise silences keeping the lenght of the audio file [on hold]

    1er mars 2019, par Lya1981

    I have an audio which is 200 seconds long.
    I run the following command, which removes silences within the threshold specified :

    sox in.wav out.wav silence 1 0.1 1% -1 0.5 1%

    Once those silences are removed, the audio becomes 100 seconds long, which means I am losing my original time stamps.

    I need to basically blank out / mute those silences (they are variations of white noise), leaving equivalent gaps in their place in order to keep the original length and timestamps within the audio.

    Is there any way to do it with exactly the params above, just not trimming it but blanking it out ? They produce the perfect outcome but I really need to keep the time stamps...
    Thank you in advance !

  • FFMPEG/libavfilter drawtext scaling without affecting video [duplicate]

    23 avril 2019, par Captain Jack

    This question already has an answer here :

    How can I scale drawtext without affecting the input video ?

    Here’s my attempt - this filter is applied in C but is equivalent to -filter_complex in command line.

    [in]drawtext=text='Test Text': fontcolor=white: fontsize=w/40: x=w/20: y=h*16/18:shadowx=1:shadowy=1,scale=iw/2:ih/3[out]

    The above does scale text but it also affects video as it’s part of the drawtext input.

    I tried things like :

    nullsrc=s=iwxih[ns];
    
[ns]drawtext=text='Test Text': fontcolor=white: fontsize=w/40: x=w/20: y=h*16/18:shadowx=1:shadowy=1,scale=iw/2:ih/3[text];
    
[in][text]overlay=0:0[out]

    But it doesn’t seem to like nullsrc and it hangs... or I am doing something wrong.

    Any ideas ?
