 I could never understand those commit numbers. Which repo are they
 referencing? My checkout has no such commit hash.

 There are two commits about undefined behavior. I'm guessing you're
 referring to the second one. I have actually checked with an automated
 script that same sample, albeit not with 4kbps. It's a bit low to be
 included in standard A/B tests, but I'll add it and re-run.

 This command crashes FFmpeg, after the commit "AAC encoder: fix undefined
 behavior".

 {{{

 experimental -b:a 4k out.mp4

 Past versions before the commit, such as N-79171-ga35a4a5 was safe.

 In this commit
 
http://git.videolan.org/?p=ffmpeg.git;a=commit;h=66edd8656b851a0c85ba25ec293cc66192c363ae
 I guess libavcodec/lpc.c line 179 is meant to be {{{i < len / 2;}}}.

 {{{
  170 double ff_lpc_calc_ref_coefs_f(LPCContext *s, const float *samples,
 int len,
  171int order, double *ref)
  172 {
  173 int i;
  174 double signal = 0.0f, avg_err = 0.0f;
  175 double autoc[MAX_LPC_ORDER+1] = {0}, error[MAX_LPC_ORDER+1] =
 {0};
  176 const double a = 0.5f, b = 1.0f - a;
  177
  178 /* Apply windowing */
  179 for (i = 0; i <= len / 2; i++) {
  180 double weight = a - b*cos((2*M_PI*i)/(len - 1));
  181 s->windowed_samples[i] = weight*samples[i];
  182 s->windowed_samples[len-1-i] = weight*samples[len-1-i];
  183 }
  184
  185 s->lpc_compute_autocorr(s->windowed_samples, len, order, autoc);
  186 signal = autoc[0];
  187 compute_ref_coefs(autoc, order, ref, error);
  188 for (i = 0; i < order; i++)
  189 avg_err = (avg_err + error[i])/2.0f;
  190 return signal/avg_err;
  191 }
 }}}

 And we can get a 1.2% speedup if we exclude cos function from the loop.

 {{{
 /* Apply windowing */
 double cos_onestep = cos((2*M_PI)/(len - 1));
 double sin_onestep = sin((2*M_PI)/(len - 1));
 double cos_isteps = b;
 double sin_isteps = 0;
 for (i = 0; i < len / 2; i++) {
 double sin_newsteps;
 double weight = a - cos_isteps;
 s->windowed_samples[i] = weight*samples[i];
 s->windowed_samples[len-1-i] = weight*samples[len-1-i];
 sin_newsteps = sin_isteps*cos_onestep + cos_isteps*sin_onestep;
 cos_isteps = cos_isteps*cos_onestep - sin_isteps*sin_onestep;
 sin_isteps = sin_newsteps;
 }

 Update: I found the main reason why fdk is so far ahead - basically, I/S
 is way too conservating, to the point where it barely gets used. I'm
 toying with making it far more aggressive.

 Which version?

 The bugs on TNS that were fixed recently make a big difference in
 perceived quality (not so much on PSNR)

 A Bad news.
 FDK-AAC still beats FFmpeg's native AAC encoder by a significant margin.

 I suggest then you revalidate the results. No need to do the whole test
 again, start with a canary (a sample that was particularly troublesome),
 to see if it now compares better.

Comment (by atomnuker):

 Flagged the LTP profile as experimental. We have enough bug reports to
 work on to fix LTP. Crashes on the aac_low profile are the main priority
 right now.
 Also removed the FAAC-like coder, since it has been marked for removal for
 over a month.

 Generally yes, however aacenc was experimental in the last release, which

Comment (by klaussfreire):

 I just pushed a fix for the assertion failure on short_block_test_2, and a
 few other artifacts that were exposed by that sample. There are some
 artifacts remaining still, but I'm having a hard time pinpointing where
 they come from, so I thought I should push before you're done with your
 listening test ;)

 Now the faad decode and the low bitrate encodes above are properly working

 But this will fail.

 It's correct as it is. You can enable AAC-Main (and thus prediction) in
 two ways: set the profile via -profile:a aac_main or set the prediction
 flag via -aac_pred 1. Setting one will set the other as well, since you
 can't have prediction without the profile being set and you can't have the
 profile set without prediction (well you can but it would be a hack as
 you'd just set all scalefactor bands to disable prediction).

 It is correct since the option aac_pred will enable AAC-Main prediction,
 even though it's not the name of the profile. Hence why it's listed there.

 -aac_pred 1 enables -profile:a aac_main and -profile:a aac_main enables
 -aac_pred 1

 It's in the pipeline.

 Just doing some regression ABX testing, since the objective (PSNR) A/B
 script pointed out some seemingly significant regressions (until now I
 couldn't confirm anyone with ABX but I'm not done testing yet)

 Is the faad's bug work-around ready?
 I have thoroughly tested ffmpeg77652. In LC profile above 22kHz and
 32kbps, the native encoder seems to be stable.

Comment (by klaussfreire):

 Well, time for an update...

 I did some tests, and faad's problem is with correlated PNS bands (PNS +
 ms_mask). It seems to be applying the M/S transform even though the specs
 clearly state that when PNS is used in conjunction with ms_mask bits, it
 should not.

 I'd consider that a faad bug, but we are indeed producing "weird"
 bitstreams (we signal correlated PNS when only one side uses PNS, which
 makes the ms_mask unnecessary). Avoiding that weirdness works around
 faad's bug (and avoids possibly triggering similar bugs in other
 decoders).

 I'm working on that patch now (thoroughly testing now).

 It's perfectly stable under normal operating bitrates and settings until
 you start testing it to the extremes with variable bit rate (please don't
 use it) and aac_main (don't use this either).
 Considering it's already used in professional broadcasting (with aac_pns 0
 since that's what causes the instability) I say it's stable. It survived a
 whole week of fuzzing after all.

Comment (by klaussfreire):

 I believe the assertion failure in comment:456 and comment:464 has been
 fixed by the last commit.

 I managed to reproduce comment:459, but I'm still investigating it. I'm
 suspecting it is indeed a bug in faad related to either M/S coding or I/S
 coding.

Comment (by klaussfreire):

 Oh, I hadn't seen the -profile:a aac_main in comment:456, without it, it
 doesn't crash anymore, but with it it does.

 AFAIK, the only difference there is main prediction (aac_main enables main
 prediction).

 I'll look into it later.

 The encoded sound collapses on FAAD2 ( Ahead Software MPEG-4 AAC Decoder
 V2.7 ).

 I failed to reproduce it on NeroAACDec 1.5.1.0.

 Can you attach or email the compilation2.wav file or something that helps
 reproduce this?

 I've tried a few samples with faad and couldn't yet reproduce it.

Comment (by atomnuker):

 All of the asserts happen because of PNS. Disable it with -aac_pns 0 and
 you'll see you won't get any more. Claudio and I are working on a fix,
 it's a hard problem to solve.

 First someone would need to determine if its maybe faad thats broken.
 No software is ever perfect.

 If it doesn't re produce with mpeg2_aac_low, its likely related to PNS, as
 thats the only feature that gets turned off over aac_low.

 solve?

Comment (by Kamedo2):

 The new AAC output cannot be decoded properly by the faad decoder.

 {{{
 ffmpeg77208 -y -i abc\compilation2.wav -c:a aac -b:a 96k out.mp4
 }}}
 {{{
 faad -b 1 out.mp4 out.wav
 }}}
 results in collapsed sounds.

 {{{
 ffmpeg77208 -y -i abc\compilation2.wav -c:a aac -b:a 96k out.mp4
 }}}
 {{{
 faad -q -b 4 out.mp4 out.wav
 }}}
 decoding to 32bit float also results in collapsed sounds.

 {{{
 ffmpeg77208 -y -i abc\compilation2.wav -c:a aac -b:a 96k out.mp4
 }}}
 {{{
 ffmpeg77208 -y -i out.mp4 -c:a pcm_s16le out.wav
 }}}
 The same AAC output decoded by the new FFmpeg is OK.

 {{{
 ffmpeg77208 -y -i abc\compilation2.wav -c:a aac -b:a 96k out.mp4
 }}}
 {{{
 ffmpeg72585 -y -i out.mp4 -c:a pcm_s16le out.wav
 }}}
 The same AAC output decoded by older FFmpeg is also OK.




 {{{
 ffmpeg76735 -y -i abc\compilation2.wav -c:a aac -b:a 96k -strict -2
 out.mp4
 }}}
 {{{
 faad -b 1 out.mp4 out.wav
 }}}
 72585, 76735 was OK, but the 76851, 76877, 76976, 77208 suffer the same
 problem.

 Wasn't one of claudio's changes supposed to get rid of this particular

 It should have. It did in all the cases I tested. I'll have to try and
 reproduce this particular case later.

Comment (by Kamedo2):

 Another crash example, probably another arithmetic overflow like
 comment:440. I think anything above -q:a 3 should be clipped to -q:a 3,
 because I don't think of any practical use, and to simplify the testing
 procedure.

 Replying to [comment:450 llogan]:
 > Appears to be a regression, but I did not run a bisect. Attached sample
 input file from Zeranoe forum user Zaoshi.

 Bug seems to only happen with intensity stereo enabled. The newest patch
 by klaussfreire fixes the bug. Might look into a quick fix but it's a
 lower priority than reviewing that patch, considering how many artifacts
 it fixes.

 Appears to be a regression, but I did not run a bisect. Attached sample

 Thank you, but it still crashes on 80kbps. This N-76863-g8000d48 is after

 Hm, I can't seem to replicate either. Does it crash at any other bitrate
 for you?

Comment (by klaussfreire):

 ANMR isn't getting any love yet.

 It will take some time, I discovered some nasty roadblocks in ANMR's
 approach.

 Twoloop keeps giving away lessons that are useful for ANMR too, so my
 objective is to get twoloop to its full potential before I start massaging
 ANMR.

 Just pushed a commit which improved LTP and fixes the crash. Give it a
 try. New version is N-76858-g1e5dbb3.

 Kamedo2:
 I've improved TNS and have made it the default (-aac_tns 1).
 I've also added LTP support for voice or piano music encoding, use
 -aac_ltp 1 (or -profile:a aac_ltp) to test it. Both features are in
 current git master.

 Claudio has 2 small fixes to merge. Hopefully won't take long.

 Hi,
 No the file is not meant to be playable, it's the output from a tool
 designed to make crazy inputs in order to crash decoders (or in this case
 encoders).

Comment (by Kamedo2):

 The fuzz1.wav file seems to be improperly delivered. This seems to be a
 stereo 48kHz 16bit linear wav file, but the header is 52 C9 46 46, as
 opposed to usual 52 49 46 46(RIFF), and 'fmt ' chunk have 10 02 00 00(528)
 length when normally and from context 10 00 00 00(16).

 Kierank, is the wav file playable in your environment?

Comment (by atomnuker):

 Kamedo2: yes, all encoder options now start with "-aac_":
 {{{
 #!div style="font-size: 80%"
 ffmpeg -help encoder=aac
   {{{
 AAC encoder AVOptions:
   -aac_coder E...A... Coding algorithm (from -1 to 3)
 (default 2)
  faac E...A... FAAC-inspired method
  anmr E...A... ANMR method
  twoloop  E...A... Two loop searching method
  fast E...A... Constant quantizer
   -aac_msE...A... Force M/S stereo coding
 (default false)
   -aac_isE...A... Intensity stereo coding
 (default auto)
   -aac_pns   E...A... Perceptual noise substitution
 (default auto)
   -aac_tns   E...A... Temporal noise shaping (default
 auto)
   -aac_pred  E...A... AAC-Main prediction (default
 auto)
 }}}
 }}}

 Any option set to automatic means that the profile will determine it by
 default, unless it is set via the command line. Any option not set to a
 default 'auto' means the default value indicated will be set. Also,
 "-aac_ms" is not boolean as indicated but can be set to '-1' which means
 it will be automatically used when there will be an encoding gain.

 Keep in mind the psychoacoustic system currently doesn't account for the
 cutoff which the new coder introduced, leading to bits being wasted and
 the quality being decreased. Claudio will be pushing a patch to fix that.
 This only affects heavy synth samples but should fix a lot of bugs which
 might be related currently. This is also what's currently blocking us from
 removing the 'experimental' flag.
 Also, I still have to merge my LTP patches, which will happen later today.

 Kamedo2: Not sure how but I got an email invitation from Shion to Slack
 (Audio Video Encoding Community) which you are apparently a member of. I
 understand enough Japanese to kinda understand the email and I'd love to
 join but I'm still learning, let alone understanding technical jargon.
 Sorry :|
 Maybe after I know a little more.

 Not yet, no. I'll change it to false when I commit my LTP changes.

 Since this appears to be the aac encoder development thread I have been
 fuzzing the encoder and get this crash a lot:

 (2304 combinations total)
 {{{--aac_coder anmr}}} seems to be unstable and prone to crashing.
 {{{-aac_coder faac}}} and {{{-aac_coder fast}}} often ignore bitrate
 blatantly.

Comment (by klaussfreire):

 Neither anmr, faac or fast were modified.

 It is possible that they need to be updated to avoid the crashing,
 although I don't see how exactly. You could try confirming whether earlier
 revisions also exhibit that behavior, and how far back.

 `faac` will probably be scrapped, `fast` will have to be rewritten, and
 `anmr` is a big question mark at present. I've been working on ANMR and
 some problems have surfaced that don't seem easy to resolve, or at all
 possible with ANMR's approach. Surely it can be made not to crash, but
 beyond that I'm unsure how far we can push ANMR.

 For now, the priority is `twoloop`.

 Yeah, I asked on IRC but you seemed to be away: did you build with
 assertion_level=2? Can you share a sample that reproduces the crash? (or
 add the fuzzer as a fate test?)

 I don't see many ways in which that crash could happen. The only way I can
 think of has an assert that should have tripped earlier.

 I have tested 75156-gfd8b90f. At 128kbps with IS, with PNS is better.

 http://wiki.hydrogenaud.io/index.php?title=Joint_stereo#Intensity_Stereo
 Intensity stereo is by definition a lossy coding method thus it is
 primarily useful at low bitrates. For coding at higher bitrates only mid-
 side stereo should be used.

Comment (by klaussfreire):

 In my tests, it has usually been the case that as you increase the
 bitrate, IS is used less while MS usage increases, naturally due to the
 R/D model used. If you see otherwise, it would be useful to know and have
 a sample to better tweak the model.

 192k, 320k, q1, q2. Stereo 192k 32000Hz is especially worsened.

Comment (by atomnuker):

 Huh, that's odd. The changes which I made to PNS today (at 12:39 UTC,
 commit b6cc8ec7ec) brought PNS closer to what it used to be before but
 fixed the warbling artifacts at lower frequencies (it's used alot more
 now). The changes to the IS which fixed the bug yesterday (1956cfbaedd36)
 shouldn't really have done much to the quality at all and I didn't hear a
 difference.

 74961-g61009a7 is before I made my PNS changes from yesterday, so are you
 sure that the last current git master still sounds worse? The PNS commit I
 made yesterday did reduce PNS usage too much (before I fixed that today).

 Either way, I'll take a listen to what the encoder sounded like before and
 try to see if it's better in the current master.

 Thanks, nice to know someone's using the encoder.
 Make sure to reencode them once the encoder's ready :-)

 Fixed the bug. Probably fixes quite a lot of IS artifacts too.

 This sound will crash the FFmpeg, when the sampling rate is 96kHz.

 I tried many sine sweeps but it seems that the bug only happens when one
 of channel is inverted.

 There's something weird happening in the search_for_is for one of the
 phases.
 Will submit a patch in a few hours and reply here for you to test.

  This rare sample and this command induces infinite loop on the current
 git head.

 I cannot replicate this bug anymore so it's probably fixed, could you test
 with the newest git master to see if it causes problems?

 I'll look into what causes the faac coder to get stuck at high bitrates.
