Hello I am developing a frame enhancement filter for the need of a video control application. I am developing on a OMAP4 pandabaord on ubuntu with the Texas Instruments hardware accelerated gstreamer pipeline (1080PPfps decode), anyhow I think my question is rather general. I am a beginner in gstreamer so please do not hesitate to redirect me to the doc if my question is already answered somewhere. My project consists in a video filter that transforms the yuv decoded frames before being displayed (for example a sepia filter to display frames in sepia color). What is the best way to add my filter in the installed gstreamer pipeline such that it becomes part of my video chain? Please see below more details: - I wish to use the installed and omap4 optimized gstreamer/totem pipeline to enable full video stream decode and display with my filter on. - I created a gstreamer plugin/element for my filter with the gst-template framework, but how to make it part of GstPlayBin2? - I looked at the pipeline graph of totem and gst-launch: they both use the playbin2 module, and I would like to add my filter in-between GstURIDecodeBin and GstPlaySink (input from src0 and output to video_raw_sink through gstinputselector). Is is possible to add and link a new element here without breaking the full bin? It is not either on the input or the output of playbin2 so I do not really understand how to just create a playbin2 element in my application and delicately insert a new element inside... - do I have to modify the source code of PlayBin2, add my filter, recompile and install it on my board to have my added features naturally enabled when I play videos? Or is it possible to tell existing gst-launch and totem applications to add a user filter plugin in the installed video processing? Thanks for your help Jacques
