Bug#439238: vlc segfaults on theora

[Arieh Skliarouk]

package: vlc
version: 0.8.6.c-3

I tried to resize an ogg video and stream it and got segfault. To isolate
the case, I took vlc-endorsed ogg stream from
ftp://streams.videolan.org/streams-videolan/reference/ogm/theora-a4_v6-k250-s0.ogg

And tried to resize it and stream:
vlc theora-a4_v6-k250-s0.ogg --loop -Irc --sout
'#transcode{vcodec="theora",width=320,height=128}:standard{access=http,mux=ogg,url=:1111}'

Here is the output:
VLC media player 0.8.6c Janus
Remote control interface initialized. Type `help' for help.
[00000297] main private: creating httpd
[00000301] mux_ogg private: Open
status change: ( new input: theora-a4_v6-k250-s0.ogg )
status change: ( audio volume: 256 )
status change: ( play state: 1 )
Segmentation fault

If I do the same using DIV3/MP3 codec, vlc works:
vlc theora-a4_v6-k250-s0.ogg --loop -Irc --sout
'#transcode{vcodec="DIV3",width=320,height=128}:standard{access=http,mux=ogg,url=:1111}'

What irony, GPLed program works with proprietary codec better than with open
one... :-(

I can provide stack trace, but IMHO it is useless, as you should be able to
reproduce the problem easily.

Could be the bug is in libtheora0 though.
