Hi, I'm trying to install videocache-1.6 in Ubuntu 7.10 with squid-2.6.14 and python-2.5 . I had no trouble in installing the package. I have changed appropriate username and apache conf.d directory both in setup.py and videocache.conf . As instructed in readme, I also appended video cache config in squid.conf at the last line.

I can browse the empty directory via browser also [http://cache-address/videocache/]. But in log file I'm getting, DOWNLOAD_ERR with below messages. In tmp file of videocache, I see lots of flv files with 0 bytes. What might be the issue?

log file

Hi!

Are you sure you changed proxy and cache_host options in /etc/videocache.conf file? The second check should be that if you have allowed your proxy machine to access itself as a proxy in the squid acls?

Please check if your videocache works after correcting the above things. If it doesn't, please reply back with your /etc/videocache.conf pasted somewhere like pastebin.

Thanks for considering videocache :)

HI there I need help about this problem. I have problem similar as described here.
I have the same problem on Ubuntu server 8.04. I can install all the files needed but it is not working, videocache does not cache videos at all.
I have changed proxy and cache_host options in /etc/videocache.conf file.

I followed instructions in the page about needed packages, than installed them as described but it is not working at all.
I am confusing, about it I tried to install it for many many
times even I reinstalled my complet server.

Hi Beny,

Can you please paste your /etc/videocache.conf and /var/log/videocache/videocache.log file on pastebin? Also please check your /var/log/squid/cache.log for any python tracebacks.

Thanks for considering videocache :)

Hi,

Pls find my /etc/videocache.conf :

http://nabinlimbu.pastebin.com/d5e2f21dd

I have allowed http_access for local server including my network also. I have reconfirmed in squid.conf .

- Permission for /var/spool/videocache is also assigned to "proxy" user

http://nabinlimbu.pastebin.com/m6a5cafd9

- apparmor and iptables both are stopped.

- I can browse empty directories via http://cache4.himaltech.com/videocache/

- Appended lines in squid.conf are :
http://nabinlimbu.pastebin.com/m5e8e3d0c

- I have reloaded both squid and apache2 service.

But, I still get same error log saying DOWNLOAD_ERR in log file.

I have similar problem "DOWNLOAD_ERR YOUTUBE" but i was pretty sure the problem is about SELinux. i keep getting avc denials each time i played a video on youtube. i tried disabled the SELinux, and videocache works just fine. the problem is i don't know how to configure SELinux. any help please...

You are right. SELinux should be turned off for videocache to work. To permanently disable SELinux either add

setenforce 0

to your /etc/rc.local file or just disable it from GUI. Thanks for sharing the trick :)

hi. thanks for reply.
turning off SELinux might be bad option.
my way is to create a policy which allow denied permission using audit2allow.
further explanation can be found in man pages of audit2allow or http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385

i think mine is a success. for reference, this is content of my local.te

Hello Joseph,

Can you please try replacing your /usr/share/videocache/videocache.py file with the videocache.py python file from here? And then restart squid service.

Thanks for considering videocache :)

Hi,

thank you for the download link. This seems to solute the first problem which has been pasted above.

But with the newer videocache.py I'm running into some other trouble.

2008/12/28 20:25:07| WARNING: url_rewriter #7 (FD 13) exited 2008/12/28 20:25:07| WARNING: url_rewriter #6 (FD 12) exited 2008/12/28 20:25:09| WARNING: url_rewriter #5 (FD 11) exited 2008/12/28 20:25:09| WARNING: url_rewriter #3 (FD 9) exited 2008/12/28 20:25:10| WARNING: url_rewriter #8 (FD 14) exited 2008/12/28 20:25:10| Too few url_rewriter processes are running FATAL: The url_rewriter helpers are crashing too rapidly, need help!

Normally the first video-cache after a squid restart is successful but afterwards there only the WARNING in the log and furthermore only the FATAL.

Thank you for you efforts and you nice application!

Happy New Year!

Axel

Hi Axel,

Check for the following things

1. SELinux - Enforcing selinux may lead to videocache misbehavior.
2. IPTables - Make sure iptables are configured to allow port 9100 so that XMLRPC Server can be used.

Happy New Year and Happy Holidays :)

Hi Jamie,

1. Please check permissions of /var/spool/videocache and its subdirectories.
2. Please check that your squid acls allow your proxy server to access internet via itself.

Thank You!
