What's p->encode when you have that id? Maybe you have an mpeg decoder
but not encoder.

At first it would seem that this problem would be caused by not

the conditional on line 7 is analyzing to true for an empty AVCodec

hitting line 8 when p is empty, and id is "CODEC_ID_MPEG2VIDEO" and
p->id is
empty.
The weird part is that when stepping through the codecs, on one of the
rotations, it does find a codec where p->id is
"CODEC_ID_MPEG2VIDEO", but
for some reason the conditional on line 7 does not analyze to true
in this
case. This seems very odd to me.
Any ideas?
(Excerpt from utils.c)
1 AVCodec *avcodec_find_encoder(enum CodecID id)
2 {
3 AVCodec *p;
4 p = first_avcodec;
5 while (p) {
6
7 if (p->encode != NULL && p->id == id)
8 return p;
9
10 p = p->next;
11 }
12 return NULL;
13 }
