  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

    lavc/qsv_hevc : correct QSV HEVC default plugin on Windows

    1. Old logic meaned : everywhere, except Windows, ffmpeg has to use HW
    
acceleration, but on Windows ffmpeg has to use (unavailable) software
    
HEVC by default
    
2. Software HEVC is available only if you provide corresponding
    
software MediaSDK library, which isn't provided with ffmpeg. More
    
information could be found in
    
https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/samples/readme-encode_linux.pdf
    
3. HW HEVC decoding/encoding are available on Windows in the driver by default
    

    Note : Default case should be the most common case but this change still has potential risk
    
on windows if HW path is not supported(or doesn't work as expection).
    
(See the historical disscution : https://lists.libav.org/pipermail/libav-devel/2016-November/080419.html).
    
In such case, two options suggested :
    
1. Use the option "-load_plugin hevc_sw" to switch SW path manually.
    
2. Or report bug to Intel windows driver if your GPU can support HEVC HW codec.
    
  (HEVC decoding is supported since Braswell, and encoding supported since Skylake)
    

    Patch started by Landgraph. Add similar change for hevc decoder and bump a new version.

  • Working with raw output from ffmpeg 'gdigrab' on Windows

    7 mars 2023, par jugglingcats

    I'm trying to capture high quality screen recording with the minimum CPU load (what we're recording is already CPU intensive and suffers slowdown if encoding is being done at the same time as screen recording).

    &#xA;

    I'm using this command :

    &#xA;

    ffmpeg -f gdigrab -t 00:00:05 -i desktop -pix_fmt yuv420p -vcodec copy -y testing.avi&#xA;

    &#xA;

    When I open this in Windows Media Player or VLC it sort of works. It's the right size and duration, but the pixels are messed up, as shown below.

    &#xA;

    output in media player

    &#xA;

    Ultimately I'd like to be able to re-encode this to something smaller, again using ffmpeg, but I can't find the right ffmpeg incantation/options for this given the raw input file generated by the first command.

    &#xA;
