 I don't really understand your issue (do you think what is printed is
 wrong or unclear?) but in any case, please provide the command line that
 allows to reproduce the issue together with the complete, uncut console
 output to make this a valid ticket.

Comment (by cehoyos):

 I wanted to ask you to test what happens if you put xsub subtitles into
 videos with both higher resolutions like 1440x1080 and much lower
 resolutions than pal or ntsc but I don't have command lines to test right
 now.

Comment:

 I don't think ffmpeg is capable of writing a HLS stream without at least
 an audio component. Until then, you can workaround this by writing an
 audio stream in addition to the subtitle. Also you might want to use
 -fix_sub_duration flag if converting from dvb teletext.

 I don't think ''intended'' is the right word: It's how lossless
 compression of 16bit rgb is implemented in ffv1.

 It's might be not a bug because it would not lead to crash.
 Is it not the bug if  the code which is not lead to crash ?
 when the code run "s->lambda_sum / s->lambda_count", and "s->lambda_count"
 can be "0" ? the divider can be "0" ?

 I don't think so, from your original report I wasn't able to guess that
 you see a crash.
 How can I reproduce the issue?

 This issue is fixed by git commit
 
[http://git.videolan.org/?p=ffmpeg.git;a=commit;h=7a65aef00d113a38e0d1a54df49eead9df6aa15c
 7a65aef00d113a38e0d1a54df49eead9df6aa15c].

 Now ffmpeg git master is correctly compiling when both libopenjpeg and
 libopenjpeg2 are installed.

 It works when I use `-strict -2` but the format named is `gbrp16le`.  Is

 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.
