H263 Bitstream

H263 Bitstream

hai

Any one know how to get the picture header information .I using (I263_32.drv
ver 2.55.016).for compresseion.where the GOB bit or Byte started.

Here my bitstream's first 12 bytes.
00 00 80 02 1D0C80 0C04 6B CB 8A.

Here i try to get the picture header info
0000 0000 0000 0000 1000 00 (PSA)22bits
00 0000 00 (TR)8Bits
10 0001 11(PTYPE)8bit cause the 6-8 bits indicate PLUSPTYPE is inclueded.(otherwise this shoud be 13 bit)
01 0 (UFEF)3Bit
100 1100 10 (MPPTYPE)9Bits
00 0000 0000 1100 0000 0100 0110 1011

Is this correct or wroung .the 8th bit of MPPTYPE shell be 0 but here 1 that bit is reserved bit.

help me to get correct picture info. and also i attached the bitstream data here.

Hi,

you should refer to H.263 documentation for detailed info about bitsream syntax
