Hi, I am trying to include one more video editing feature in cheese. For that I wanted to use appsink method and capture video content from buffer edit it and push it back to stream. I have studied the example code of appsink-src and wrote something very similar. but I am not able to generate the "new-buffer" signal . g_signal_connect (priv->video_save_bin, "new-buffer", G_CALLBACK (on_new_buffer_from_source), data); I am not able to tell the pipeline to generate this signal. I quite new to gstreamer, can someone help me out. Please.
