Hello Good Day,


I want to perform multimedia dissemination. For which I can use the traces from the website http://trace.eas.asu.edu 

 

All the video traces have fields such as: Sequence Number, Frame Type, Time [ms], Length.

 

Omnetpp will set the size of a packet, type of packets,... and send.

 

 Sir, I found your video interface library for omnet++ that I can use by modifying according to environment. But, I have a question: If a packet is lost, then how can I visualize the impact of the lost data on the video quality….

 

Please updates me, its very urgent...

 

Kind Regards,

Sarwar,

Trace is supported in inetmanet

https://github.com/aarizaq/inetmanet-3.x/blob/inetmanet-3.0/src/inet/applications/udpapp/UDPVideoStreamSvr2.cc

https://github.com/aarizaq/inetmanet-3.x/blob/inetmanet-3.0/src/inet/applications/udpapp/UDPVideoStreamCli2.cc

 

 

It is possible that you need to modify a bit the file, the frame type must be of one char, in other case the code will throw an error. Sometimes the first frame in the trace has more than a letter like type.

The client register the number of frames of every time that it has received, you can compare the number of frames of every type that have been lost and compute the distortion

Thank you Sir,
I believe the paper is very useful and related.

Sir, i can use PSNR, SSIM or the MOS metrics. I want to see the impact visually by displaying the distorted mpeg-4 images of the video. Is it possible....

Thanks Alot.
