MPEG-4 layered video coding for scalable streaming particular, streaming, specified, software, decrease

andy

HI!
I'm developing an adaptive streaming video application for my thesis project.
With quot;adaptivequot; i means that the server can increase/decrease (in real-time) the bitrate of the video in relation to the bandwidth conditions.
I would you like to use the layered scalable video encoding specified in MPEG-4 specfications, but i cant't find any coding software that impements this particular feature.
All MPGEG-4 coding programs I have tested don't support the layered scalable video spatial quality.Do you know some programs that use this option? (free or not, is not a problem)

thanks a lot for any help!! This is an explanetion of what I means with quot;layered encodigquot;:

welcome to !

is this part of iso 14496-10 or -2?

I think it is part of ISO/IEC 14496-4 or ISO/IEC 14496-5...

nope its part of 14496-2, you might want to grab a copy of the specs (4 is conformance, 5 is the reference software)

also i doubt that any opensource encoder supporting this exists, except the reference software maybe, which i would recommend you to look at

moved to the new codecs forum as its not an avc issue

From here:
mpeg/sta...g-4/mpeg-4.htm

Overview of the MPEG-4 Standard
Quality scalability allows a bitstream to be parsed into a number of bitstream layers of different bitrate such that the combination of a subset of the layers can still be decoded into a meaningful signal. The bitstream parsing can occur either during transmission or in the decoder. The reconstructed quality, in general, is related to the number of layers used for decoding and reconstruction.
If Bond can confirm, as far as I'm aware, this is the list of the ISO/IEC 14496 sub-sections: -

Part 01: Systems
Part 02: Visual (Video and Still Images)
Part 03: Audio (formerly ANSI/ISO/IEC 14496-3:1999)
Part 04: Conformance testing (formerly ANSI/ISO/IEC 14496-4-2001)
Part 05: Reference software
Part 06: Delivery Multimedia Integration Framework (DMIF)
Part 07: Optimised reference software for coding of audio-visual objects
Part 08: Carriage of ISO/IEC 14496 contents over IP networks
Part 09: Reference hardware description
Part 10: AVC (Advanced Video Coding)
Part 11: Scene description and application engine
Part 12: ISO base media file format
Part 13: Intellectual Property Management and Protection (IPMP) extensions
Part 14: MP4 Container
Part 15: Advanced Video Coding file format
Part 16: Animation Framework extension (AFX)
Part 17: Subtitles
Part 18: Font compression and streaming
Part 19: Synthesised texture stream

Copies of the individual specifications can be obtained from here: -
ansidocstore/find.asp? Just put: ISO/IEC 14496 in the search box

And other places of course

Ok, thank you.
But anybody knows a software that provide mpeg-4 layered conversion?
