[Ffmpeg-devel] Possibly wrong tags assigned in movenc.c

according to IS-14496-1, when muxing to MP4 the tag assigned to H264 in the

object_type field present in the DecoderConfigDescriptor is 0x21, 
while ffmpeg assigns 241 (in ff_mov_obj_type). 

Additionally, stream_type should be 0x4 for video
and 0x5 for audio, instead movenc uses 0x11 and 0x15 respectively.

Are the current values specific to quicktime?
