 Hi, all:
 I used demux mp4 which built as H264 & aac
 When the program stopped, there was info "[aac at xxxxxx] Qavg -nan"
 I found this info would generated by av_log() in
 aac_encode_end(AVCodecContext *avctx).
 The code like this "av_log(avctx, AV_LOG_INFO, "Qavg: %.3f\n",
 s->lambda_sum / s->lambda_count);"
 the problem was that the s->lambda_count was "0" and the type of it is
 int.
 thinking of the value "0" is divided ?
 is this a bug ?
