ffmpeg.exe MOV to WebM x64 crash

[Vince]

I'm trying to transcode a MOV recorded with a canon camera to webM

ffmpeg simply crashed

commands: C:\Users\Vincent\Documents\Visual Studio 2010\Home Media Builder\Home Media Webbuilder\bin\Debug>ffmpeg64.exe -v 9 -loglevel 99 -i "C:\Users\Vincent\Documents\Visual Studio 2010\Home Media Builder\TestWebFiles\videos\2004\2004_03_March\2004_03_23\2004-03-23_001.MOV" -acodec libvorbis -ab 192k -strict experimental -ar 44100 -b 400k -f webm -vcodec libvpx "C:\Users\Vincent\Documents\Visual Studio 2010\Home Media Builder\TestWebFiles\videos\2004\2004_03_March\2004_03_23\2004-03-23_001.WEBM"

following is a copy paste of my command prompt output:

file 001 was too large to upload, file 002 is from the same camera also producing the crash

[Carl Eugen Hoyos]

Does the crash also happen if you use -an or -vn?

If the crash only happens with -an, does it also happen if you choose any other video encoder? (Try ffmpeg -i 2004_03_23\2004-03-23_001.MOV -an -qscale 5 out.mkv)

If the crash only happens with -vn, does it also happen if you choose any other audio encoder? (Try ffmpeg -i 2004_03_23\2004-03-23_001.MOV -vn -ar 44100 out.mkv)

backtrace missing (works fine on Windows), please see ​http://ffmpeg.org/bugreports.html

[Vince]

No, of course I tested other output formats. They work fine. Also the 32bit version of ffmpeg works fine. It only applies to the 64bit version

[Carl Eugen Hoyos]

Backtrace missing, please see ​http://ffmpeg.org/bugreports.html

Please provide a minimal command line, i.e. one that either contains -an or -vn (or confirm that it does not crash with either).

[Vince]

does crash

[Vince]

If you encounter a crash bug, please provide the gdb output, backtrace and disassembly using the the ffmpeg_g debug binary as follows:

gdb ffmpeg_g

In gdb, type 'r' for run, along with the rest of the ffmpeg command line:

r <rest of command line>

When gdb encounters its problem, run the following commands and copy/paste the output into your bug report:

bt
disass $pc-32,$pc+32
info all-registers

With older gdb versions, use disass $pc-32 $pc+32.

I have no idea how to do this. I'm just using the ffmpeg.exe

[Carl Eugen Hoyos]

Where does your ffmpeg.exe come from?

[Vince]

from ​http://ffmpeg.zeranoe.com/builds/ as linked on the ​http://ffmpeg.org/download.html website

I just googled some, found out people claim the vpxenc.exe of the original makers of the webm standard also crashes on x64.. I'll try this myself, maybe it's a bug from the webM guys

[Vince]

vpxenc.exe x64 doesn't crash, But produces crappy output. Only snow, and video length is under 1 second..

guess something is wrong with their encoder under x64..
their x86 is working just fine..

Crash Dump File

[mbradshaw]

I too am having this problem. It's not just with MOV files, as the same thing happened with an MP4 file as well. I was trying to encode a video to VP8/OGG/WebM and ffmpeg crashed. I have attached two files that were generated by Windows from the crash. One describes my computer setup, and the other describes some information about the state of FFmpeg. I have another crash dump file, but it's ~7MB, so it's a little too big to upload here with the file size limit.

Here is the exact output from the console, including my exact command:

I will try to look into this more, particularly using the vpxenc.exe (x64 version). I do not have this problem when using FFmpeg x86 version. Only with the FFmpeg x64 version. I also do not have this problem on OS X 10.6 or Ubuntu 11. I am using FFmpeg-git-f884ef0-64-bit-Static (from 2011-10-13) from the Zeranoe builds.

The input video in this part comes from a QuickTime sample from the iTunes website. I will attach it.

vpxenc.exe also produces snow for my input video. The length is approximately equal to that of the input video. I haven't used vpxenc.exe very much though, so I need to test it more and make sure that the snow isn't being caused by me passing in crappy parameters. I'm more familiar with FFmpeg.

I don't have any gdb output from ffmpeg_g, as I don't have ffmpeg_g.exe. If I had it, I would be happy to produce some gdb output.

Thanks for making a great program; I hope that this can get resolved (whether it's WebM team's problem or FFmpeg's), as it could cause some problems with encoding on some of our servers that we use.

If there is any additional information I can provide, please let me know.

One of many sample videoes that produces the error for me

[Carl Eugen Hoyos]

Replying to mbradshaw:

I have attached two files that were generated by Windows from the crash. One describes my computer setup, and the other describes some information about the state of FFmpeg.

Afaict, these files do not contain any useful information.
Please provide a backtrace etc. as explained on ​http://ffmpeg.org/bugreports.html

[Carl Eugen Hoyos]

I compiled libvpx without assembler optimization for win64, tested vpxenc successfully, recompiled ffmpeg with libvpx support and the resulting binary encodes fine to webm.

Please reopen only if you can provide a backtrace, gdb works fine on win64.
