[M4IF Technotes] MPEG-4 video stuffing bits

[giuseppe.spampinato st.com]

     Hi everybody,
     in the MPEG-4 standard
     at the end of each frame you have to insert
     stuffing bits to be byte-aligned.
     But could you insert also different consecutive
     bytes in this manner?
     And which value these bytes must contain?
     Reading the standard this seems to be possible
     and the value of the stuffing bytes should be "011111111",
     but Momusys decoder does not support this feature,
     while Microsoft decode these bytes correctly.
     Is it a bug in Momusys decoder (also in the last version
     contained in the file w4711.zip) or it is not allowed
     by the standard.
     If it is not allowed by the standard, where can I
     insert other bytes to satisfy the Video Buffer Verifier
     and avoid underflow? 
     Many thanks!!!
