Webcam receiving

[jandem]

Last week i had some free time to get webcam receiving (no sending yet) working. It needs to be optimized and cleaned up a bit, but if you are brave enough to try it.. You have to build the libmimic python module for the webcam video codec first:

- on Debian/Ubuntu: sudo apt-get install build-essential python2.5-dev (other distro's should have similar packages, you have to install gcc and python header files)
- checkout or update emesene trunk from SVN
- cd to emesene directory
- python setup.py build_ext -i
- ./emesene

Do this at your own risk! There are a number of known bugs and trunk builds can be unstable.
If you can't connect, try to forward port 6891 in your router...

Enjoy!

Great!

COOOOOOOOOOOOl! it works :D

after : python setup.py build

copying plugins_base/currentSong/__init__.py -> build/lib.linux-i686-2.5/plugins_base/currentSong
copying plugins_base/currentSong/Exaile.py -> build/lib.linux-i686-2.5/plugins_base/currentSong
creating build/lib.linux-i686-2.5/onversation_themes
creating build/lib.linux-i686-2.5/onversation_themes/irc
error: can't copy 'onversation_themes/irc/theme': doesn't exist or not a regular file

One solution :

Replace :

package_data = {'': ['conversation_themes/*/*', 'smilies/*/*',
                           'sound_themes/*/*', 'themes/*/*', 'hotmlog.htm']},

By

package_data = {'': ['/conversation_themes/*/*', '/smilies/*/*',
                           '/sound_themes/*/*', '/themes/*/*', '/hotmlog.htm']},

in setup.py

I think the slash character can be replaced by any character... Not sure

This is really good news, i could never imagine that we could see something like this so soon.
Can't wait until we both have sending/receiving support.

But regarding to libmimic wouldn't it be better to use Farsight? i would believe that some day audio will be implemented and then it would be much nicer to just use one library that does both audio & video.

As you can read there, the Farsight webcam plugin is very old and doesn't work anymore...

Ahh okay

[guillaume]

not true. farsight just been implemented in empathy.

but heh, if it work well with libmimic, no need for something else

Just a question:
will we ever have python coding of webcam support?

I'm not a programmer at all so I don't understand perfectly the differences between various languages so...if you want to explain to me better this point, I'm ready to learn

I have found some bugs:
1) When someone starts a webcam session, a pop up appears and it asks me if i want to accept it, but there's a bug: it shows the message "Accept webcam from master@***.it?", but that's my email address, not my friend's one.
2) It lags a lot! It can lag up to 20 seconds, and when it stops lagging, it shows the rest of the video at increased speed (it can reduce a video of 5 minutes to a video of 1 minute)

No, unlikely. We use the C code only for the webcam video codec. Python is alright for most applications, but it's quite slower than C (because it's interpreted, no typed variables and pointers, etc.). Codecs are CPU-intensive, so I think that porting it to Python would make it too slow. Another reason is that the codec was already written in C, porting it to Python would take extra time and have almost no advantages.

Yes, known bugs. The second one has to do with the network sockets I think, because the decoding is quite fast.

Unfortunately it doesn't work for me, i get a message if i want to accept the cam, and if i do, i just get high cpu usage and after a long time i see 'webcam canceled'

Ok, very satisfying answer. Thank you

it's very nice.

Congradulations. It works very nice.
