[FFmpeg-user] AVCodecContext profile not being set

A little more information.
MiniDLNA is using avformat_open_input to retrieve the AVFormatContext, but when the AVCodecContext for the video stream is taken from the AVFormatContext the profile value is always -99 instead of 66 for the h.264 encoded aac 520 file.
The more I look into this the more it looks like a possible FFMPEG error.

Subject: [FFmpeg-user] AVCodecContext profile not being set
So I'm using MiniDLNA, but I'm seeing the the DLNA.ORG_PN is not being set correctly for AVC_MP4_BL_CIF15_AAC_520 files. That is mpeg4 files with AAC audio.
After some tracing in their code, I found that this is because the AVCodecContext->profile value is set to -99, which is not valid. My understanding is that avcodec is responsible for setting this. I disable a lot of options in ffmpeg to reduce the size as much as possible, I'm worried that I indirectly disabled the option for setting the profile...
Any help would be much appreciated.
