runtime parameter adjusting

Thành Trung Nguyễn
Hi all,

Is there any one know if there's existing elements that can adjust parameters at runtime. For examples: adjusting video framerate, bitrate or something like that.
Also, if you know or got any ideas about that, please tell me.

Thanks

Have a look at GstParamSpec in the api docs. There is
#define             GST_PARAM_MUTABLE_PAUSED
#define             GST_PARAM_MUTABLE_PLAYING
#define             GST_PARAM_MUTABLE_READY

be aware that its not widely used. So if you have a particular element where you
feel a parameter change is getting ignored under some condition, please file a
bug about it.
