Description

(vlc ticket 9446)
J-B pointed to a dvb recording that plays fine with WMP, does not play with FFmpeg nor vlc. mplayer -ac faad plays audio with incorrect speed (indicating SBR afaict).
The problem is apparently related to CRC checks in the ADTS stream (ISO/IEC 11172-3, subclause 2.4.3.1).
