Re: [Ekiga-list] Ekiga h263p/h264 crashes at early stage of libavcodec initialization

Hi Lele,

first you should compile opal (or at least the plugin) with debug symbols.
Which revision of opal are you using? Are you sure the header files of ffmpeg at compile time
match the actual lib that is being loaded by the plugin?
