I put the gstreamer mailing list in CC. I suggest that you subscribe  
there and discuss the proposal there too. We can also talk on irc  
about this. If you look at http://gstreamer.freedesktop.org/apps/ you  
can see that most applications are media-players. Your brief proposal  
describes a nice tool that we don't have in this form. There are some  
tools already for subtasks, but some of those seems to be not that  
active. Some examples
convert sounds : Sound Converter
convert to ogg files : OggConvert
There is also GEntrans targetting transcoding.

I definitely encourage you to write a proposal. As this is an  
extensive project I recommend that you structure the features into  
iterations (basic features, addition #1 (e.g. audio related), addition  
#2 (e.g. video related)). I hope you also plan to work on this beyond  
the summer.

Ok, hello community!

I was writing the application for this project, and I created a wiki
with more details:
http://gstreamer.freedesktop.org/wiki/MediaTrans
(the name could be another)
I would love to have suggestions and criticisms!
Also, this project is an application using gstreamer, so could it be
judged as a gnome application too? I was in doubt with it, but using
the criteria by Christian Schaller, on his blog, I'll need much more
help in gstreamer than in interfaces.
And Stefan, I pretend to continue in the project the Summer of Code,
as I am in OLPC after I participated GSoC last year (also this project
could be ported to Sugar - OLPC's OS too).

Thanks for all!
Roberto

Hi,

I looked at your proposal. The application would make a nice addition to the
gnome platform. Still its a long  way to get there. Transcoding media would be a
nice service as such, but also a good addition for applictions like Conduit. One
'missing' piece on the way there are encoding profiles [1]. I think it would be
good to rescope the project a bit - right clicking a file in nautilus and
transcoding to something. The dvd ripping part is handled by thoggen already.
Although I assume thoggen would be interested in the encoder options.
The third part - changing the audio track of a video - is maybe better done in
e.g. pitivi (which again would love to get a encoder opetions dialog).

I would offer to mentor your project, if you are fine with setting a smaller goal.

Hello Stefan and community

By rescope you mean to simplify the project to not implement an entire
application, but implement a kind of service to be used by nautilus,
conduit, pitivi and so on? And this service could offer a dialog box
or something else to make the transcoding operations? If so it's nice
to me, as one of my intentions is to integrate with user environment,
with gnome and user applications. Nice you liked and offered to mentor
me!
Also, if so I'll change / compact the wiki page (and probably change
the google application's name from "Media application" to "Media
service" or "Multimedia service" while there is time)

Thanks!!
Roberto

Yep, exactly. All those application would do duplication efforts otherwise.
Having the same UI would also help users as they only need to know one dialog.
