 ## APV Sample Description
 
 ###	Format of sample
-When APV coded bitstream is encapsulated in a track with APVSampleEntry, each sample shall contain one and only one access unit of APV coded data. The format of sample shall be same as the raw_bitstream_access_unit, the length field of four bytes preceeding the access unit data, as defined in the section 12.1 of [APV codec specification](#apv-codec).
