  • ffmpeg.exe not detecting UScreenCapture

    14 janvier 2021, par TenG

    I have two version of ffmpeg on the Windows 7 PC.

    


    The first came installed with an application, which uses ffmpeg to capture video/audio of the desktop. This works.

    


    It uses an older version of ffmpeg, so I downloaded the latest version and tried the same command and it reports that the devices are not detected.

    


    Commands run :

    


    Old FFMPEG :

    


    ffmpeg.exe -list_devices true -f dshow -i dummy

    avcodec/magicyuv : Don't waste stack space

    Now that the HuffEntries are no longer sorted by the MagicYUV decoder,
    
their symbols are trivial : The symbol of the element with index i is i.
    
They can therefore be removed. Furthermore, despite the length of the
    
codes being in the range 1..32 bits, the actual value of the codes is
    
<= 4096 (for 12 bit content). The reason for this is that the longer
    
codes are on the left side of the tree, so that the higher bits of
    
these codes are simply zero. By using an uint16_t for the codes and
    
removing the symbols entry, the size of each HuffEntry is decreased from
    
eight to four, saving 16KB of stack space.

  • Convert horizontal video to mobile screen by FFmpeg

    12 mars 2023, par Dopicsi

    I use FFMEG to convert the videos. Currently, if a horizontal video is uploaded, I see it enlarged on mobile. I want the horizontal videos to be vertically centered with black at the top and bottom.

    &#xA;

    The application only works in vertical mobile view, all videos are played this way.
