Comment (by arut):

 I've realized just now I know the reason. Successive H264 decoder configs
 may contain new SPS for new picture resolution. That's why it's important
 to send every new config when remuxing from one streaming format to
 another streaming format. Mp4 muxer does not expect those. It uses
 extradata only once when writing mp4 moov atom and does not make any use
 of successive H264 configs.
