FFMPEG crashes encoding AAC audio at 32k/1ch AAC, but not at 31k/1ch or 33k/1ch

Description

Summary of the bug:
FFMPEG crashes when output audio bitrate is set to 32k and one audio channel, however it encodes successfully at 31k and 33k. This appears to be file specific, as it seems to encode most files successfully to a 1ch/32k bitrate, but one file I have seems to trigger the crash.

How to reproduce:

ffmpeg.exe -i "input.mp4" -c:a libvo_aacenc -ac 1 -b:a 32k "output.mp4"
ffmpeg version N-56980-g1ab9f32
  built on Oct  8 2013 18:08:35 with gcc 4.8.1 (GCC)

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

I tried to attach a sample, but I couldn't extract a segment that was less than 2.5MB. Despite instructing FFMPEG to use copy only a 60 second portion of the file, it kept extracting a segment of 5 minutes or more. input.mp4 is an extracted audio only portion that seems to still trigger the crash, and original.mp4 is the file as I received it before I attempted to transcode it.

I've tried it on two different Windows machines (Win7 and Windows Server 2012), and it crashed on both machines. Perhaps this is a Windows only bug?

So far you have unfortunately not provided any information that would allow me to answer...
(And I hope you agree that I did try to reproduce the problem.)

comment:5 by soulbabel, 11 years ago

My apologies for not attaching the missing info. I am running this command on Windows 7 x64 using the latest static build from Zeranoe. The command crashes after a few seconds, so the log file ends abruptly when it reaches the 4 minute mark in the file.

Does it also crash if you use -acodec aac -strict -2 ?

in reply to: 6 comment:7 by soulbabel, 11 years ago

Replying to cehoyos:

Does it also crash if you use -acodec aac -strict -2 ?

It encoded successfully. Here is the command line I used:

ffmpeg -v 9 -loglevel 99 -report -i original.mp4 -y -vn -acodec aac -strict -2 -ac 1 -b:a 32k -ar 44100 output.mp4

versus the crashing command line:

ffmpeg -v 9 -loglevel 99 -report -i original.mp4 -y -vn -c:a libvo_aacenc -ac 1 -b:a 32k -ar 44100 output.mp4

Here is the log file from the successful encode:

Without a backtrace, I don't think there is much we can do.

follow-up: 10 comment:9 by Kamedo2, 11 years ago

I tried the input.mp4 and it crashed on Win7 64bit, Core i7 870. I tried to use the foobar2000 decoded wav as an input, but it also fails. I tried many diverse wav files and quiet speech samples seem to cause the crash problem. I'm going to post another problematic sample that crash the vo-aacenc. I compressed the file into FLAC, but using the original wav doesn't help.

Replying to Kamedo2:

All of these 3 examples crash.

Please provide backtrace etc. as explained on http://ffmpeg.org/bugreports.html
I don't think anything can be done without it.

0x009fa2fe in voAACEnc_pow2_xy ()

comment:12 by Michael Niedermayer, 11 years ago

voAACEnc_pow2_xy() is a function from libvo-aacenc, has someone tested if libvo-aacenc without ffmpeg shows this issue too?
Also a full backtrace with linenumbers and disassembly of the crashing place and register values could help to better understand this
And the inability of carl to reproduce this might be due to differing libvo-aacenc versions (but iam just guessing here)
With which libvo-aacenc version does this happen?
Iam on linux ATM and it doesnt happen here, neither with valgrind nor address sanitizer.
