I am also working on the same but could not achieve it to any grate extent. Your inputs can change the way i am trying. Please help.

I find if we don't do any library cutting down, the gstreamer core library is big, about 700-800 KB, but that will not match my requirement, the time cost on loading library is long. Another issue is that gst_init() cost much time. So my goal is to make the best of  reducing gstreamer library size and gst_init() time. For library size cutting down, I have tried some ways, such as 1. disable many unused features 2. disable debug 3, not use xml registry etc at last, the core library size is about 350KB For gst_init(), I also did some tunning on startup options, such as "disable option parsing" etc. But I think it is not the best that gstreamer can reach, maybe there are many other ways to do these, so if we can share our experience, I think we can get better result. Appreciate for your comments and reply. thanks Best Regards Zhao Liang ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
