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.
