 Summary of the bug:
 An incorrect AVPictureType is returned during demux for two slice per H264
 encoded streams. When calling av_read_frame to demux a packet from a
 Mpeg-2 H264 stream, the returned avpacket AVPictureType is
 AV_PICTURE_TYPE_NONE in the case where it should be AV_PICTURE_TYPE_I.
 This only happens when the H264 frames has two slices per frame as shown
 in attached image.
 How to reproduce:
 Demux an H264 I frame when the H264 is two slices per frame.
