MPlayer crash on some WMV files (and the fix)

I was having a problem playing some WMV files. MPlayer would crash with a signal 11. Here's a snip:

I had a tough time finding it but eventually I found the answer here:

If you have all your codecs installed and are having this problem here's what you can do. Add this to your /etc/sysctl.conf:

Code: Select all

# Allow MPlayer to play DMO WMV files (DLL problems without this)
kernel.exec-shield = 0

and while you are in there you might as well add this:

Code: Select all

# Stop annoying startup message in MPlayer
dev.rtc.max-user-freq = 1024

Then to make the above kernel settings take effect immediately do this as root:

# sysctl -p

Enjoy!

You got one that you can't play? If it's not pr0n and it's not personal do you have a link so I can see if I can play it?

Struggled to find an example that wasn't porn, but here goes:

http://66.184.207.35/media/bomb_saddam/ ... ll.wmv.zip

It opens, but then chokes at any random point.

PS. I'm going to bed so don't expect a reply for 8 hours or so

That one plays just flawlessly for me (even in full screen). Nice video choice by the way, I had seen that one before. I actually have worked on several items shown in the video and have also flown on several of them.

running FC2 here and after editing /etc/sysctl.conf, nothing changed.

ultimately i just want to play a wmv file, http://www.sorethumbz.com/swg/request.php?2, that someone linked to on Neworder, so first i went to apt-get. after it installed it just didn't have the wmv codec, and i instantly realized that i'm in for another adventure.

after downloading several different RPMS, i decided to just go through the source. kept getting into dependency warnings, and i didn't feel like going rpm hunting.

i went to the mplayer website and after browsing around downloaded the codecs from http://www.mplayerhq.hu/MPlayer/releases/codecs/ and placing them in /usr/local/lib/codec. that was easy enough. i downloaded the source by using their CVS download. after that i did a configure (noticing that i had to find and install libpng and libpng-dev, i decided to opt out of the gui install for now), and make/make install.

now, from just reading the above i can see that i'm missing some config files, and it did recognise the wmadmo codec, but not the ffwmav2 codec. now, when i got the codecs from the mplayer site, i actually got the first two, because i wasn't sure which i needed, and untarred both of them into /usr/local/lib/codec. i figured "latest win32 codecpack" would have been all i needed

Honestely, all I ever do is "apt-get install mplayer" and download the win32 codecs and put them in the /usr/lib/win32 directory. Everything works just great. I'm sure there are several threads on this site about it, easy as pie.

Does it do that on *all* videos? If not, does it do it on all *.wmv files (from different sources)? I have run across a couple of *.wmv files that would do the same thing you mention, if I recall it is from home movies someone has created. I think there are certain types that can not be played currently (Microsoft tries really hard to make things so proprietary that only they can play them as I am sure you are aware). I'm sorry I don't know enough about MPlayer and video formats to know which exact things don't work. Might be a question for the MPlayer mailing list. I think for the most part xine uses pretty much completely separate libraries and codecs to play so if it also can not play them then I suspect something with the video and would do more research on the exact format that the video is in.

Of course if it's not too big you could always upload it to me (or give me a link to where I can get it) and see if I can play it. If I can then there is surely something wrong with your setup and we should be able to continue to trouble-shoot. You can FTP it to voidmain.is-a-geek.net and put it in the /upload directory.

I tried with both videos from this thread (actually the code I posted is the output from the seond movie linked to by siplus) but the one Tux linked to gives the same output.
I use FC2 on my work laptop now and I have the impression that mplayer is a lot less stable now than it ever was before (for me anyway).

mplayer doesn't segfault on all .wmv files though, and the crashes for "bad use of CPU/FPU/RAM" don't happen anymore, I used to have that a lot with RH9 ...
All the other video formats play fine except for Real Media files, mplayer segfaults on those to

I compensated that by installing Real Player for Linux but I don't like it too much/

I tried switching the video driver from xv to x11 since this helped me out a couple of times before but nothing changes.

For very nice playing of all the real stuff thet "Helix Player" works very nicely. It's the open source version of the Real Player. I actually do like it even though the video/audio format is proprietary. If you have to go there, Helix is not a bad way (and it plays right in the browser nicer than anything else I have used). Too bad it only works for the Real formats.

As far as the MPlayer thing the only thing I can think of is that I must have some more stuff installed that you guys don't (divix libraries, other video libraries, etc).

Sorry, I forgot to update you on this. I rebuilt myself teh 1.0pre4 RPMs and my problem seems to be resolved now. (I was using pre3)

I just installed Helix this week, it's a nice app and a good show of some support for the GPL way o' life.
I still think that MPlayer trumps it in technical terms and it's sheer breadth of ability. Hopefully the MPlayer team can improve their handling of Real(Networks) formats by taking a peek, the fact that you can't seek in some rm files with MPlayer is rather annoying.
