try the package from http://pkgbuild.com/~ioni/ffmpeg

Looks like  FS#24615 , works fine with glibc-2.13-5

Would you mind to specify the architecture too?

@Michael time to report this upstream to mpd. i cannot do more than telling you do get a proper backtrace[1] and say that our ffmpeg is from release/0.7 branch [2]

I found that the bug was 2 uninitialized AVFormatContext pointers... I wrote a patch ..
   mpd-0.16.3_ffmpeg_sigsegv.pat... (0.8 KiB)
Comment by Michael (SiD) - Friday, 24 June 2011, 17:11 GMT
works with the patch, thanks
:)
Comment by Angel Velasquez (angvp) - Friday, 24 June 2011, 17:29 GMT
Give me few hours to be at home and apply that patch.

Would you mind to send it to the mpd upstream? (in case you didn't sent it yet)

Thanks!

I sent it there too :)
