Please read the documentation. Have you removed the first two lines as specified below?

http://www.nsnam.org/doxygen/structns3_1_1_udp_trace_client.html

Sends UDP packets based on a trace file of an MPEG4 stream trace files could be downloaded form: http://www2.tkn.tu-berlin.de/research/trace/ltvt.html (the 2 first lines of the file should be removed) A valid trace file is a file with 4 columns:

• -1- the first one represents the frame index
• -2- the second one indicates the type of the frame: I, P or B
• -3- the third one indicates the time on which the frame was generated by the encoder
• -4- the fourth one indicates the frame size in byte

If no valid MPEG4 trace file is provided to the application the trace from g_defaultEntries array will be loaded.

You go here http://www2.tkn.tu-berlin.de/research/trace/ltvt.html

Select which file (quality/codec) you like.

e.g. Jourasic Park, MPEG-4, medium quality 

http://www2.tkn.tu-berlin.de/research/trace/pics/FrameTrace/mp4/indexcf9e.html

It opens a page with links for two traces (terse/verbose). 

Assume you want the terse, you "RIGHT" click on the link and "SAVE LINK AS". That will save the DAT file on your computer. 

Then you open it with a TEXT EDITOR in order to remove the first two lines.

I think they're too big (and too many) to be posted here.

The list is attached. If you can't access the website, we can send you with a private mail the file you need, choose one or two. Please pick not only the video, also the ind of compression you choose (compression, bit rate and so on).

Also, send me a mail, the group doesn't show your mail address.

Cheers,

T.

LMGIFY.... http://www2.tkn.tu-berlin.de/research/trace/trace.html

They describe all the process they used to extract the sources. If you're not totally dumb, you can find all the infos you want. E.g., QCIF = 176 × 144
