[Mp4-tech] How to make MoMuSys reference software error resilient

[Damodaran, Usha (UMKC-Student)]

Is the Microsoft code code for MPEG4 video decoder error resilient? Or is it that only MoMuSys is not error resilient? I have to do something similar with Microsoft decoder and now I am wondering if it will provide me the required error resilience.

Subject: [Mp4-tech] How to make MoMuSys reference software error resilient
Hello,
I am working on a project called "Adaptive Real Time
Video Streaming".Basically,I need to encode a raw
video file(AVI or YUV) to MPEG4 encoded bitstream.The
encoder should give one base layer and one or more
enhancement layers.Then according to the bandwidth
availabe to the user,I will drop frames from the
enhancement layer and stream the video to the
client.At the client end ,again I need to decode the
MPEG4 file to give back the AVI or YUV video file.
I ams using MoMuSys codec for the purpose.
But,as soon as I drop a frame from the enhancement
layer,the decoder goes for a toss.
I suppose that the reference software does not include
error resilience.
How can I modify the reference software so that it is
able to decode bitstreams with errors,i.e. it supports
error resilience?
Kindly reply at your earliest convenience.
Thanks & regards,
Saru Malhotra
1. It can't encode/decode in real time.
2. It is non error resilient,so as soon as I drop
frames from Enhancement layer,it fails to decode the
MPEG4 stream.
