Instead of this, add APV to the list in https://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavformat/movenc.c;h=4bc8bd1b2ab765c2b9f5f5dfc2dcb77361f2b944;hb=HEAD#l6697 so the first packet is always copied to trk->vos_data in case par->extradata is not set.
After that, ff_isom_write_apvc() can either write the extradata as is if it's already a configuration record, or generate it if it's just a packet of PBUs (See ff_isom_write_hvcc()).
