MPEG-4 video coding in IPP

Tamer_Assad · ‎01-06-2010

MPEG-4 part 2 uses H.263 video coding
MPEG-4 part 10 uses H.264 video coding

IPP provides H.263 and H.264 Encoder/Decoder, also an MPEG-4 Encoder/Decoder.

I wonder:
1) Which video coding is used by IPP MPEG-4 Encoder/Decoder, as I understand it is an ITU standard with sub
standards/parts?
2) if it is H.263 or H.264, how is it compared to the existing IPP H.26x?

Regards,
Tamer

Hi Tamer,

if you pay attention to IPP audio-video-codecs documentation (namely, readme.htm files in codecmpeg4-enc folder) you may see that IPP MPEG4 encoder implements:

The encoder supports the standard ISO/IEC 14496-2 with certain restrictions. Only the following features are supported in the current version:

I-VOP
P-VOP
B-VOP
S-VOP
AC/DC Prediction
4MV
Un-restricted MV
P-VOP with OBMC
Quantisation Method 1,2
Videopackets
Short video header
Data partitioning
Reversible VLC
Interlacing
Basic sprites
Quarter-Pixel Motion Estimation
Global Motion Estimation (Number of Warping Points 0 an 1)
VBR and CBR Control

Vladimir

Hi Vladimir,

Thank you for your response.
Im bit confused, isnt ISO/IEC 14496-2 is the same as the MPEG-4 part 2 (H.263) ?

Best regards,
Tamer

Hi Tamer,

The ISO/IEC 14496 part 2 specification defines several video coding profiles. One of them is basic H.263 coding (it does not include the latest H.263 annexes).
