btw, vlc-2.1.5-2 with ffmpeg-1:2.3.3-2 works good.

The same error occurs with flv files.

vlc package probably needs to be rebuilt ( by using makepkg )

it was the solution in july when ffmpeg was updated

Nope, rebuild changes nothing.

Did you try to recreate the vlc cache ?

/usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugin

I hadn't, but I did now. No change.

same problem here with 2.1.5-3

force closes when opening .rmvb files

2.1.5-2 was working

Same problem here with flv file. And strangely, if I open vlc first, then drag the flv file to vlc, it works (did not test with rmvb file).
Comment by patrick (potomac) - Saturday, 04 October 2014, 13:49 GMT
seems to be an incompatibility with glibc-2.20, in dmesg I can read this immediatly after a crash of vlc :

segfault at ffffffc0 ip 00007fee631c7d04 sp 00007fee492e3708 error 4 in libc-2.20.so

I have similar backtrace when trying to open .pdf file (.rmvb too). I narrowed problem to libavformat_plugin.so calling av_probe_input_format() with improper argument, when codec cannot be found, but didn't go deeper - anyway it seems be fixed in latest vlc beta version (v2.2.0-pre3). I attach minimaly changed PKGBUILD if someone is interested.

I'm unable to reproduce it with vlc 2.1.5-3 and ffmpeg 1:2.4.2-1. The file posted by Ken works just fine.
Comment by Timo Schmid (bluec0re) - Sunday, 12 October 2014, 22:00 GMT
temporary fix until vlc 2.2 gets stable.

Edit:
Btw. I was able to reproduce it with several file formats by trying to play a folder containing some vids.

I backported the patch mentioned by Timo. Please check if vlc 2.1.5-4 fixes the issue for you.
Comment by Doug Newgard (Scimmia) - Monday, 13 October 2014, 07:05 GMT
That seems to have done the trick.
