Hi, during my rewrite of the management of vorbis extradata in demux_mkv and demux_ogg I realized that some demuxers store extradata in sh->codecdata, others in sh->wf+1. ad_ffmpeg seems to read data from both :) What's the right place to store these informations? In my fixes I used sh->wf+1 because I didn't realize there was sh->codecdata, but now I'm no more so sure.... Please, shed some light. Nico
