  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • avformat/matroskaenc : Simplify writing Void elements

    avformat/matroskaenc : Simplify writing Void elements

    Reserving space in Matroska works by writing a Void element. And until
    
now this worked as follows : The current position was recorded and the
    
EBML ID as well as the length field written ; then the new position was
    
recorded to know how much more to write. Afterwards the actual writing
    
has been performed via ffio_fill().
    

    But it is unnecessary to explicitly use the positions (obtained via
    
avio_tell()) to find out how much still needs to be written, because the
    
length of the ID and the length field are known. So rewrite the function
    
to no longer use them.
    

    Also, given that ffio_fill() uses an int parameter and given that no
    
current caller (and no sane future caller) will want to reserve several
    
GB of space, make the size parameter of put_ebml_void() itself an int.

  • FFmpeg library in WPF

    20 avril 2022, par MikeTMG

    I am building a softwere that can decode and encode using Wpf and c#, and I want to do that using, FFmpeg libary. I saw the ffmpeg autogen warpper but I couldn't find any documantion for its function.&#xA;Can someone please find me one ? Or better, give me better warrper.

    &#xA;&#xA;

    I already tried FFMpegCore, its working but very slow. For Exaple it takes 20 seconds to decode a specific frame.(And i have monstruos computer)&#xA;If will be happy if ou could give me better warpper, or a guide for ffmpeg.autogen.&#xA;Thanks in advance.

  • avformat/matroskadec : Fix heap-buffer overflow upon gigantic timestamps

    avformat/matroskadec : Fix heap-buffer overflow upon gigantic timestamps

    The WebM DASH Manifest demuxer creates a comma-delimited list of
    
all the timestamps of index entries. It allocates 20 bytes per
    
timestamp ; yet the largest 64bit numbers have 20 decimal digits
    
(for int64_t it can be '-'+ 19 digits), so that one needs 21B
    
per entry because of the comma (resp. the final NUL).
    

    The code uses snprintf, but snprintf returns the strlen of the string
    
that would have been written had the supplied buffer been big enough.
    
And if this is 21, then the next entry is written at an offset of 21
    
from the current position. So if enough such entries exist, the buffer
    
won't suffice.
    

    This commit fixes this by replacing the allocation of buffer for
    
the supposedly worst-case with dynamic allocations by using an AVBPrint.
