 Thank you for the replying.
 I am sorry for my confusing issue.
 the printed is vivid that "Qavg -nan".
 I meant that there is bug in  libavcodec/aacenc.c, line:846 "av_log(avctx,
 AV_LOG_INFO, "Qavg: %.3f\n", s->lambda_sum / s->lambda_count);".
 s->lambda_count was 0 in some time, could "s->lambda_count" be 0 ? same as
 a/b, b should not be 0, is that right ?

 Anyway the details I gave unclearly.
 I didn't run the command "ffmpeg balabala..."
 I invoked the API directly in my codes.

 The backtrace show this:
 (gdb) bt
 #0  aac_encode_end (avctx=0x7fc68c045ac0) at libavcodec/aacenc.c:844
 #1  0x00b3254a in avcodec_close (avctx=0x7fc68c045ac0) at
 libavcodec/utils.c:2545
 #2  0x0041238b in OutputProc::Close (this=0x273a600) at
 mediaproc.cpp:1162
 #3  0x004156a0 in ConvertdProcess::CloseClear (this=0x273a4a0) at
 convertdprocess.cpp:562

 at mediaproc.cpp:1162 is
 avcodec_close(ofmt_ctx_->streams[i]->codec);

 Is there enough for the issue ? If I should show more details about the
 issue, tell me
 Thanks again.
