Crash Data

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:44.0) Gecko/20100101 Firefox/44.0
Build ID: 20160126223146

Steps to reproduce:

The best way to reproduce this error is to use Firefox 44, go to a facebook feed and scroll through until you find an embedded html5 video.  Upon autoplaying, the browser crashes.  This only happens on my computer with a GeForce 8400GS/PCIe/SSE2.  


Actual results:

The browser crashes immediately.  If running in the terminal it consistently throws the following: I/SampleTable( 5926): There are reordered frames present.

The crash report is as follows:

I cleared out ~/.mozilla, thereby removing all the addons and all other configuration, and the error persisted.  Here's a crash report without the addons: bp-5232d751-4628-43ad-99f7-3fa872160209

Glad I'm not the only one.  Have you tried the suggestion above about setting media.hardware-video-decoding.enabled=false ?
I did and it made no difference.

it serves no purpose on linux, there's no hardware decoder available.

A link to an actual video would help...
Flags: needinfo?(jyavenard)
crashes very, and can't tell which part is actually crashing. one seems to be the audio decoder, so that's either AAC or MP3 audio.

Can you try 45 beta though? we've simplified the FFmpeg code there.

At this stage, I can only recommend that a newer version of FFmpeg be used
I already use ffmpeg 3.0
(In reply to Darko Miletic from comment #15)
> I already use ffmpeg 3.0

Certainly not with Firefox 44.
libavcodec.57 won't even be loaded by Firefox 44. 

You must be running the latest beta 45.

If you have another version of libavcodec installed at the same time, then be aware that having two versions of libavcodec installed with their respective libavutils will typically cause crashes as libavcodec.54 (from LibAV fork) incorrectly gets loaded with libavutil from Ffmpeg. We've had earlier reports of this.

If you're running FF 44, the latest version of libavcodec it will work with is from FFmpeg 2.8 (libavcodec.56)
OK, Installed firefox 45 beta from ubuntu firefox-next ppa. Found a video that crashes it always.
Open this and it bombs

The crash is in libavcodec.54 which indicates that you don't have FFmpeg 3.0 installed.
Make sure that you only have one version of ffmpeg/libav installed. Libavcodec doesn't play well when you have different versions installed from different repositories (and there's nothing we can do against it)

What is the output of: dpkg -l | grep libavcodec

Strange. And if I do dpkg -l ffmpeg I get:
ii  ffmpeg                      7:3.0.0+git~trusty amd64

What do you suggest here?

Install libavcodec from ffmpeg 2.8 or 3.0 (that is respectively libavcodec56 or libavcodec57)

The version you have installed isn't the one that comes with Ubuntu 14.04, so I have no idea what it is.
Personally, I would uninstall it and put back the one that originally ships with Ubuntu 14.04 (from LibAV 9). At least this one is tried and tested.
and how should I do that? The suggested repo on the ffmpeg site https://launchpad.net/~mc3man/+archive/ubuntu/trusty-media does not have libavcodec package (as far as I can see). 

Use static builds? http://johnvansickle.com/ffmpeg/
You can't use a static build... Uninstall the libavcodec-extra and libavcodec54 you have installed. Disable the repository that you got this package from and reinstall libavcodec54 that ships with Ubuntu 14.04 official repo.
Reinstalling of the libavcodec54 seems to be working. I would be mindful in future about mixing packages. Thanks.

I just gave firefox 45 beta a shot and am still having the issue.

bp-d103113f-17dd-4f21-9bdf-299422160308
Would you have more than one version of Ffmpeg installed by any chance?
Like libavcodec from LibAv and then libavcodec from FFmpeg. 
Or Did you install ffmpeg Libs from 3rd party repositories?

If that's like what the other poster had. Issue was with a 3rd party ffmpeg. Going back to the original one fixed the problem.

My problem is solved. I had some "suspicious" ffmpeg packages installed.

Hi there, thanks for the response. I was able to find and uninstall an ffmpeg package from when I had the chromium browser.  This leads to a delay in the crash but it still definitely still crashes:

I don't see any packages when I run `dpkg -l | grep ffmpeg`.  I do however see two packages when I run `dpkg -l | grep libavcodec`:

According to `apt-cache policy`, libavcodec-extra-54 is not installed though and libavcodec54 is installed from the standard `ttp://us.archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages` repository.  Might there be any other packages that I should inspect?

Do you remember which package(s) it was?  I've been scouring my system but can't find the culprit and am looking for anything that might be useful.
Here is my apt.log for March 8:

First I tried to re-install firefox and install the newer linux kernel but no success.
Second, i've found this topic and uninstall all ffmpeg - related packages.

I think we should close this on the basis that the offending ffmpeg version is a non-distro build.

While this error can apparently be caused by a non-distro build of ffmpeg, I still have not resolved the issue even though I have no versions of ffmpeg installed on my system.

you sure do.

your crash reports indicates a crash in libavcodec.so.54.35.0

Thanks for the response.  I might be misunderstanding this, but I believe this codec is straight from the ubuntu repository.  Let me know if I'm mistaken

but do you have another libavcodec installed? don't have to be via a package or repository.

if you search your hard disk for libavcodec* and libavutil* what do you find?

that none are installed, yet you have libavcodec crashing, there's no other choice but you having one installed somewhere.

It seems that when I remove libavcodec54, libavcodec-extra-54 is automatically installed.  If I remove that, it reinstalls libavcodec54.  However both of these packages are from the ubuntu repository.  (I had just removed libavcodec54 just before posting the above.)  Under both instances, firefox crashes.

Here's a crash with libavcodec54 installed: bp-1317cd08-1c1b-4aa7-8c0b-5ccca2160323

Here's a crash with libavcodec54 removed but libavcodec-extra-54 automatically installed: bp-095e45c9-f29d-42d4-b560-21f0d2160323
Shouldn't come as a surprise: I installed the new 16.04 and Firefox is working fine.  So glad to have my preferred browser back!
