Hi everyone !
I want to change the paramter of x264enc or omx_h264enc when this encoder are encoding the video stream,but i find after i set the pipeline state to PLAYING , i can not set the x264enc paramter , later i has changed the state of the pipe to PAUSED . so i want to know if the pipeline is running , Can i change paramter of the element in this pipeline? For example the paramter of bitrate and other paramter about rate control in the x264enc or omx_h264enc , the version of gstreamer is 0.10 ,x264 is 0.10.14 ,the omx is 0.10.35 . And i find the GstController . I have try it ,failed too.I can not understand the function of GstController in the Plugin Writer's Guide Chapter 15.
Thanks very much!
