Local install of panda nearly working: Problem with progress bar

Hello,

after nearly working a whole day I think I am quite close to getting
panda run locally.

I installed everything as described in the guide for installing panda
locally...

I have a working nginx and merb installation. I can access the admin
panel via nginx and I am able to start the upload of a video with
"Upload a test video" link. But shortly after showing the progress bar
the upload dialog shows an error message:

"Unfortunately there was an error uploading your video. We have been
notified of this issue. Please try uploading your video again
shortly."

The logfile for merb shows me:

merb : worker (port 4001) ~ Params:

It would be great if somebody could give me hint what goes wrong and
how I could fix it...

Thanks a lot!

Hi,

I believe that issue will arise if the nginx install you have doesn't have nginx upload progress module: http://wiki.nginx.org/NginxHttpUploadProgressModule

You also might find the new managed service we're testing. I've added you to the list so you should get an invite in a few minutes.

Let me know if you have any more questions.

Hello Damien,

thanks for your reply. I did compile and install nginx like described
here:

http://github.com/reddavis/panda_cap/blob/master/nginx.rb

How can I see or test if the module was really successfully compiled &
installed & added to nginx?...

My nginx configuration is as follows:

worker_processes 1;

events {
worker_connections 1024;
}

http {
upload_progress proxied 1m;

server {
listen 81;
server_name myapp.com;
root /usr/local/www/panda;

location / {
proxy_pass http://127.0.0.1:4001;
# proxy_redirect default;
track_uploads proxied 30s;
client_max_body_size 500m;
}

location ^~ /progress {
report_uploads proxied;
}
}
}

OK. I think it is not the upload_progress_module, because while trying
to upload with the panda upload dialog I get the following in the
nginx error log:

2010/01/26 21:39:18 [warn] 22337#0: *56 a client request body is
buffered to a temporary file /usr/local/nginx/client_body_temp/

81", referrer: "http://localhost:81/videos/c1dfa260-
ece8-012c-2e6e-001d09248ccc/upload_form"

So I guess that it is working.

But I also get this in the merb server log:

As you can see I tried all kind of file formats like ogg, mov, mpg and
even avi... so I now think it might be a problem with ffmpeg or the
installed codecs. Now I will try to find out what the panda merb
application is doing while reading the metadata of a video. Maybe I
can do it manually on the command line and see what happens.

If somebody has some tips how to approach this problem I would very
happy...

Thanks.

As you can see I tried all kind of file formats like ogg, mov, mpg and

even avi... so I now think it might be a problem with ffmpeg or the
installed codecs. Now I will try to find out what the panda merb
application is doing while reading the metadata of a video. Maybe I
can do it manually on the command line and see what happens.

If somebody has some tips how to approach this problem I would very
happy...

Thanks.

OK. Now I found the source of the problem. The ffmpeg version (0.5-
svn17737+3:0.svn20090303-1ubuntu6) I have seems not to be compatible
with the rvideo gem that I had... only after I downloaded and
installed the rvideo source on github from new_bamboos the
RVideo::Inspector class works again.

Before every file just was not valid!

But now I get another error:

So this is the next problem I have to fix...

OK. After some testing with irb/rvideo alone it seems as if the
capture_frame method is somehow not present.

I found this google groups entry that explains why:

http://groups.google.com/group/rvideo/browse_thread/thread/9b5805cc98a5f851/3e40fa69625c0f8a?lnk=gst&q=capture_frame#3e40fa69625c0f8a

So the question for me is, what version combination of rvideo and
ffmpeg is still working? And where do I get it (for ubuntu)?

irb(main):005:0> inspector.capture_frame("3%", '/home/BEAGILE/
govinda.fichtner/downloads/hdtest.jpg')

NoMethodError: undefined method `capture_frame' for

#<RVideo::Inspector:0xb763bfd4>

Hello again,

I got everything working now! I am using ffmpeg 0.5 and a customized
panda and rvideo version....

Hi Govinda,

I'm glad to hear you have it all sorted! If you have any changes to panda and rvideo please do commit them to your github and let me know so I can merge into master if necessary.

You may actually have another issue, because the video should upload without progress working. Was there no more info in the logs?
