[gst-devel] Question about Gstreamer Pipelines involving DVD, MP3

[Uri David Akavia]

Hello.

First of all, I apologize if this isn't the right place, but I'm a
user who has a question about pipelines involving DVDs, MP3. If this
isn't the right place, please point me to the correct one.

I want to take a DVD, and turn each scene into an MP3 (or ogg).
Personally, I would like the option of setting the tags (artist, song,
and so on), but if this is impossible, never mind. So, how do I create
such a pipeline?
I know I could (in theory) use something like thoggen to get a video
ogg, then convert it to just audio, but I don't want to go through an
intermediate (and waste the disk space).

Second, this is a general question/comment - I've used imagemagick a
few times to manipulate images (including changing size, orientation,
and so on). From my (very limited) understanding of gstreamer, I
should be able to use it to (for example), read 4 scenes from a DVD,
and write them into file when they all appear on a split screen (like
a video wall, but to a file).
However, I couldn't find a tutorial that would explain pipelines and
how to do anything beyond the basics with them. Is this just lack of
time, or do you prefer people to write applications, not use
gst-launch for manipulations?

Thank you,

Uri David
