I have found what my problem was. As the following code sample would show, I was using av_malloc to allocate an AVPacket on the heap. While I called av_init_packet to initialize the fields of the AVPacket struct, that function does not zero out the data or size field. Changing this to av_mallocz instead fixed the issue I was running into.

AVFrame* testFrame;
AVCodecContext* context;
/*
I set up the frame and context in here.
*/
int validPacket = 0;
AVPacket* packet = reinterpret_cast<AVPacket*>(av_malloc(sizeof(AVPacket)));
av_init_packet(packet);
int error = avcodec_encode_video2(context, packet, testFrame, &validPacket);
if (validPacket)
{
                // TODO: save out packet data.
                av_free_packet(packet);
}
av_free(packet);

Thanks,
David
