Thank you

Did you place the test video on both the client and the server? It seems a 
misconfiguration problem. Has the key "path" (in "VT.conf", at the server) the 
correct path to the video file? And has the key "video0" the correct file name?

Or maybe there is a problem with file permissions. Has the server read access 
to the test video?

I have try to find something that misconfiguration. The following messages are 
the log on the terminal of the server.

I run the video tester both the server and the client on the same laptop.  Is 
that OK?

Original comment by ting.ech...@gmail.com on 9 Jan 2013 at 3:22

"Is that OK?"

Yeah, there shouldn't be any problem with it.

I've managed to reproduce the error. I'm looking for the bug.

Original comment by i.uca...@gmail.com on 9 Jan 2013 at 3:34

GoogleCodeExporter commented 9 years ago 
Ok. I've got it. This is the syntax that VTServer uses to read the video file 
(VideoTester/gstreamer.py: line 56):

launch = "filesrc location="+self.path+"/"+video+" ! decodebin ! videorate ! 
video/x-raw-yuv,framerate="+str(self.framerate)+"/1 ! "

I've found that the element "decodebin" (it's part of Gstreamer) is unable to 
find a suitable decoder although it is properly installed (ffdec_h264). But 
this only happens with Gstreamer 0.10.36. The version 0.10.35, however, works 
perfectly (with Fedora 16, for example).

Right now, I have no time to seek an alternative to "decodebin", so... Try it 
with Gstreamer 0.10.35 or convert the test video to another format with ffmpeg.

I'll keep this issue opened until this error with the version 0.10.36 is solved.

Hey, 
 I still cannot configure the software on the Ubuntu 12.04. The same reason of running error.
Therefore, I try that on my Fedora 17. But I did not install the 
gstreamer-plugins-bad-nonfree. Because I didn't find the software on the web.
So, Could you give me a list of the software and their version? I found that I 
install the gstreamer on the Fedora 17, but it still are Gstreamer-0.10.36.
The errors are as follow:
[root@echo VideoTester-0.2]# VT client -g

Fedora 16 has GStreamer 0.10.35. Try with it. There is a complete list of 
dependencies at the project [http://code.google.com/p/video-tester/ homepage], 
section "Installation".

I have installed all of the software on the Fedora 16, but still error.
The error are from the client

Oh, sorry, my mistake. I forgot to include one dependency after the last 
update. Run "yum install gstreamer-rtsp-python" and try again.

GoogleCodeExporter commented 9 years ago 
yes, it is ok now.
But, the client is easy to out of response with nothing outputs. 
I don't know if I do something wrong. There is no error log in the VT.log.

Could you tell me which file contains the testing result? Because there is no 
error report again, I consider it to correct. But I did not find the file about 
the testing result such as G.1070 quality result or PSNR etc. May be in the 
temp directory?

The video processing task is very heavy (so I have to improve it). All process 
spends around 1 minute. I recommend using the GUI only to display the results 
(with File->Open). The results are stored under "temp". For example, if you 
test video0 with H.263, 128 kbps, 25 fps and UDP unicast, you can find the 
results under "temp/video0_h263_128_25_udp-unicast".

OK, but I don't know why the result is so wired. And When I using the GUI to 
display the results(File->Open), there is no reasonable file to open and 
display.
In the attachment is the result about I test video0 with H.263,128kbps, 25fps 
and UDP unicast.

"Keyboard interrupt". You are stopping the client too early. ;-) Be patient, 
give it time. As I said, around 1 minute.

Now I found the message printed by the client:

And I have checked the output file in the directory /temp. They are the same as

PS. Could you attach me about the correct running results?

I still found that the log stopped to output any messages and just like the 
client was out of response.

Is that because I did not wait the client for enough time?

GoogleCodeExporter commented 9 years ago 
13:44 to 14:47? Mmmh... Definitely, this is not the reason. Are you running the 
client and the server at the same machine? Are you using "iface=eth0" or 
similar at VT.conf? Try putting "iface=lo".

Original comment by i.uca...@gmail.com on 21 Jan 2013 at 3:11

GoogleCodeExporter commented 9 years ago 
Yes. I am running the client and the server at the same client. Actually, I run 
the client on one terminal and run the server on the other terminal on my 
virtual machine.
Yes, I am.
I will try it.
