Greetings,

1) I've been trying installing evalvid in ns2.35 ubuntu 12.04 in many ways. including in http://www2.tkn.tu-berlin.de/research/evalvid/ and http://ru6.cti.gr/ru6/research-areas...rk-simulations but how do you know exactly that evalvid is installed in your ns2?

2) i keep countering the same problem when running tfrc_vbr_sample.tcl

Make RED trace variables
Evalvid-RA: Start making GOP and Frame trace files for 29 Rate variants
invalid command name "vbrTraceFile2"
while executing
"vbrTraceFile2 create _o5556 "
invoked from within
"catch "$className create $o $args" msg"
invoked from within
"if [catch "$className create $o $args" msg] {
if [string match "__FAILED_SHADOW_OBJECT_" $msg] {
delete $o
return ""
}
global errorInfo
error "class $..."
(procedure "new" line 3)
invoked from within
"new vbrTraceFile2"
invoked from within
"set trace_file [new vbrTraceFile2]"
(file "tfrc_vbr_simple.tcl" line 325)

what i have been missing? i appreciate any king of help. Thank you

"" invalid command name "vbrTraceFile2" "" : ? A typo in `tfrc_vbr_sample.tcl' ?

thank you for your reply, actually it is not a typo.
i'm sorry i forgot to put the link where i download the sample. here is the sample : http://www.item.ntnu.no/~arnelie/eva...ra_v1.04_2.zip

i'm trying to compile your sample and i've got this following problem :
invalid command name "Agent/myUDP"
while executing
"Agent/myUDP create _o82 "

greetings, knudfl,

Re #3.

The example `tfrc_vbr_sample.tcl' is not usable with a basic "evalvid".
`tfrc_vbr_sample.tcl' is for Evalvid-RA only.
And I don't think that's what you are using ? ?

Evalvid-RA http://www.scribd.com/doc/49179873/L...lvid-RA#scribd
"" Trace Driven Simulation of Rate Adaptive MPEG-4 VBR Video ""

( I have a copy of the original `LieKlaue07-Evalvid-RA.pdf',
... the old links to the original file don't exist any more.)

dear knudfl,

actually what i'm planning to do is to analyze video transmission in network simulator. i'm thinking that your sample in #2 is really helpful, so i'm going to continue with yours. But when i'm trying to run be_a01.tcl, i've got the following error in #3, i seems can't run 'myUDP'.
any suggestion from you will do, i'm still new at this and i need help from you, master.

thank you for your reply

Re #6.

"be_a01.tcl" is an EvalVid2 file.

My test :
.... Which is the normal behavior.

dear knudfl,

there's a few question i'd like to ask

1) where can i get myevalvid2 patch? all the links i've found seems not working anymore.

2) what do i do after i download evalvid 2.7: http://www2.tkn.tu-berlin.de/researc...id-2.7.tar.bz2 . when i type 'make' there's following problem :
C mp4trace.c ...
mp4trace.c:4:27: fatal error: gpac/isomedia.h: No such file or directory
compilation terminated.
make: *** [mp4trace.o] Error 1

3) how to install precompiled binaries of evalvid?
http://www2.tkn.tu-berlin.de/researc....7-lin.tar.bz2

I'm glad to your reply, thank you.

Re #8.

Add 1) The "myevalvid2 patch" is for ns-2.28. Maybe ns-2.35 is possible ?
`myevalvid2_ns228-patching-2.tar.gz' :
https://drive.google.com/file/d/0B7S...ew?usp=sharing

Add 2) $ sudo apt-get install libgpac-dev

Add 3) Ref. http://www2.tkn.tu-berlin.de/researc....7-lin.tar.bz2
There are no "precompiled binaries" in `evalvid-2.7-lin.tar.bz2'.

dear knudfl,

i'm trying to patch it, and i've got the following error

common/packet.cc:44:16: error: conflicting declaration char** p_info::name_

what does it mean? any suggestion?

Re #10.
You will have to show all the commands you did, before the errors appeared.
""I'm trying to patch it"" : Unknown "patch", unknown "it".

! All commands are like :
$ tar xvf ns-allinone-2.28.tar.gz
$ patch -p0 < ns228-gcc40.patch
$ patch -p0 < ns-2.28-gcc410.patch <Enter> <Enter> <Enter>
$ cd ns-allinone-2.28/
$ tar xvf myevalvid2-ns228-patching-2.tar.gz
$ export CC=gcc41 CXX=g++41 && ./install

dear knudfl,

thank you for responding me so far.
i'm sorry for my incomplete explanation, actually i was trying to patch it in ns-2.35.
i'm going to follow your instruction in #11 so i'm googling your patch.
I've found your link http://www.linuxquestions.org/questi...on-4175445965/ and the explanation is pretty good but the problem is apparently your link is not working anymore. is there any newer link?

i'm working by myself for this project so i'm really grateful for your reply. thank you

Re #12.

Not much Evalvid2, it mostly evalvid in the link you show in post #12 ..

do you have any suggestion. i appreciate your reply

Re #14.

"gcc41" / gcc-4.1 : A tool not present on your OS cannot be used. Obviously.
Also : There is a misconception, a contradiction between "export gcc41",
and the answer you receive from the tcl8.4.5 configure : " ... gcc-4.1 " !


"export CC=gcc41 CXX=g++41" is an example.
Your Ubuntu OS is unknown.
Recommending the right gcc/g++ version 3.4.6 .. 4.1.2 : The OS must be specified.
a) Very important is the architecture : $ uname -m
b) And the exact version :
