gst-ffmpeg is terribly undocumented and I think there is no real need for me to use it. I need to support a handful of codecs, not every single one there is. x264enc didn't work because of unknown reasons at the time being and it really pissed me off because I know it used to work. Five minutes ago I realized why it didn't work and I got it working now. It was a serious case of PEBKAC ... To make it short, I was testing with a smaller window 800x800, H264 video size must be divisible by 2 and x264 starts counting with 0. :> I'll hack x264 as an option. > For starters, you could add most of the gstreamer plugins packages as > either suggested or recommended in the Debian source package.

This is a really neat idea. I'll probably make webm default and a requirement and x264 will be an optional feature. > but on Ubuntu, I think it's > there in gst-plugins-ugly in multiverse or restricted (correct me if > I'm wrong). If I can read this page correctly and the information is valid, it seems that uglies are in the universe. http://packages.ubuntu.com/oneiric/libs/gstreamer0.10-plugins-ugly > If you want to go with Python, I can't really help you with the > implementation details, since I am only a novice at Python > programming.

I'll see what time will bring. :) I'm quite fluent in python so it would be my first choice. Vala, however, is becoming a defacto standard for Gnome development and that's why I am considering it. > I'm allquixotic on freenode, so feel free to ping me.

I registered a channel, BigWhale will be idling there mostly. :) Regards, David -- ubuntu-desktop mailing list ubuntu-desktop@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-desktop
