gstreamer problems on AMD64

[krastano...@gmail.com]

Hi all

My cam works on mplayer (with preloaded libs) and skype, but not in
camorama and cheese. As I don't use the later I'm ok with this, and
just suspected it's problem with the distribution (ubuntu 9.04). But
when I tried using the cam with gstreamer, I didn't work. I preloaded
the needed libs and tried with v4lsrc. I tried with v4l2src, but it's
not working neither.

According to http://gstreamer.freedesktop.org/documentation/plugins.html v4l2src and v4lsrc should be used with raw frames.
According to dmesg I'm using yuv420 output format, and I can not find  useful source for it on gstreamer. Any ideas? Probably I can change the format of my cam, but that will hurt the quality of the video.

autovideosrc does not work neither

What am I doing wrong?

Solved

I needed 0002-Implement-ENUM_FRAMESIZES

I used old version. My mistake.

Thank you for your work
