  • Taille des images et des logos définissables

    9 février 2011, par

    Dans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.

    avcodec/avcodec : Sanitize options before using them

    This is how it is supposed to happen, yet when using frame threading,
    
the codec's init function has been called before preinit. This can lead
    
to crashes when e.g. using unsupported lowres values for decoders
    
together with frame threading.

    avformat/pp_bnk : Fix memleaks when reading non-stereo tracks

    Commit 6973df112275c8ea4af0bf3cb1338baecc1d06b3 added support
    
for music tracks by outputting its two containing tracks
    
together in one packet. But the actual data is not contiguous
    
in the file and therefore one can't simply use av_get_packet()
    
(which has been used before) for it. Therefore the packet was
    
now allocated via av_new_packet() and read via avio_read() ;
    
and this is also for non-music files.
    

    This causes problems because one can now longer rely on things
    
done automatically by av_get_packet() : It automatically freed
    
the packet in case of errors ; this lead to memleaks in several
    
FATE-tests covering this demuxer. Furthermore, in case the data
    
read is less than the data desired, the returned packet was not
    
zero-allocated (the packet's padding was uninitialized) ;
    
for music files the actual data could even be uninitialized.
    

    The former problems are fixed by using av_get_packet() for
    
non-music files ; the latter problem is handled by erroring out
    
unless both tracks could be fully read.

  • avformat/mxfenc : Never set codec_ul UID to NULL

    28 février 2020, par Andreas Rheinhardt
    avformat/mxfenc : Never set codec_ul UID to NULL

    mxf distinguishes codec profiles by different UIDs and therefore needs
    
to check that the input is actually compatible with mxf (i.e. if there
    
is a defined UID for it). If not, then sometimes the UID would be set to
    
NULL and writing the (video) packet would fail. Yet the following audio
    
packet would trigger writing the header (which has been postponed because
    
the UID is not known at the start) and if the UID is NULL, this can lead
    
to segfaults. This commit therefore stops setting the UID to NULL if the
    
input is incompatible with mxf (it has initially been set to a generic
    
value in mxf_write_header()).
    

    Fixes #7993.
