[gst-devel] Question on conventional properties/events to descript run-time request

[Chen, Weian]

Thanks a lot for your information.

And for resolution/frame-rate stuff, the one way we can do is to re-negotiate the caps and invoke the GST_EVENT_NEWSEGMENT event? If so do we need to set the pipeline state to PAUSE, or it can keep on PLAYING state?

thanks,
Weian

Properties can be changed at runtime. Whether this actually works is
entirely up to the particular element. GStreamer doesn't currently
have any mechanism to query whether a property can be modified in a
particular element state, though.

Most encoders do not let you modify the bitrate target at runtime -
but if you have an encoder that can do that, you should simply make
setting the property during encoding set the changed bitrate on the
underlying encoder properly.
