Sorry I was a little unclear. See below.

No.
Search the source code file libavcodec/mpegvideo.c for the line:
av_log(s->avctx, AV_LOG_ERROR, "get_buffer() failed (%d %d %d %p)\n", r,
pic->age, pic->type, pic->data[0]);
Make a note of it's line number.
(kwrite displays line numbers in the bottom left of the status bar.)
Give gdb the command:
break mpegvideo.c:285
Replacing 285 with whatever the line number was that you found.

Apart from my modifications, yes.
