Justin Ruggles	f2f2e7627f	Check mp3 header before calling avpriv_mpegaudio_decode_header(). As indicated in the function documentation, the header MUST be checked prior to calling it because no consistency check is done there. CC:libav-stable@libav.org	11 years ago

Christophe Gisquet	e7fc5d53a0	huffyuv: change statistics initialization Normally, a Laplace distribution is more typical of the residuals encoded, but for noisy input, it's both better and simpler to be safe and use a 1/d^2 distribution. Second hunk could use some renormalization but it has effectively little impact.
