I use concatdec for concat multiple stream over http protocol, by set option "safe"=0. After a failed switching from one url to another, application calls av_read_frame() again at top-level, that would cause NULL access In function concat_read_packet(), > Another solution is to add: > > if (!cat->avf) > return AVERROR(EIO); > > at the beginning of concat_read_packet().

It's much more cleaner. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
