  • avfilter/vf_paletteuse : Fix leaks of AVFilterFormats on error

    avfilter/vf_paletteuse : Fix leaks of AVFilterFormats on error

    The paletteuse's query_formats function allocated three AVFilterFormats
    
before storing them permanently. If allocating one of them failed, the
    
three AVFilterFormats structures would be freed with av_freep() which
    
does not free separately allocated subelements (namely the formats
    
array) which leak.
    

    Furthermore, if storing one of the first two fails, the function simply
    
returns and the ones not yet stored leak.
    

    These leaks have been fixed by only creating a new AVFilterFormats after
    
the last one has already been permanently stored. Furthermore, it is
    
enough to check whether the elements have been properly stored as
    
ff_formats_ref() by design returns AVERROR(ENOMEM) if it is provided a
    
NULL AVFilterFormats *.
    

    Fixes Coverity issues #1270818 and #1270819.

  • converting with the same quality

    26 mai 2019, par Sherkhan Azimov

    ffmpeg -i cam2.DAT -qscale:v cam2.avi
    When run, this returns "At least one output file must be specified", what am I missing ?
    Probably, there is another method to convert with the same quality ?
