Also push out the last frame if we have exact amount of samples. Fix the adapter flushing to not cause endless loops. Drop a redundant avail() check. |

A basclass for audiovisualizers. Takes care of re-fitting the audio-rate to video-rate. It receives audio-data at the sampling-rate. It needs to render video-frames at frame-rate. The rendering needs n audio samples (depends on subclass). The baseclass takes care of that. = Feedback = * put 'Audio' to klass as well ? = API = * should we add some basic drawing helpers to the baseclass draw_point (x,y,color); draw_hline (x1,x2,y,color); draw_vline (x,y1,y2,color); draw_rect (x1,x2,y1,y2,color); draw_box (x1,x2,y1,y2,color); // filled - would be nice if we could use cairo * shading effects - would be nice to use a generic 3x3 matrix operation, we don't run inplace anyway - this way we could also blur the background = Elements to port = gst-plugin-ugly/gst/synaestesia -> synaescope gst-plugin-good/gst/monoscope -> blend into what we have in wavescope = Elements to add = spectrascope - done spacescope - stereo wavescope - left->x, right->y - done - polar mapping = TODO = - element maker template - test for baseclass = Test it = GST_DEBUG="*:2,*scope*:4" GST_PLUGIN_PATH=$GST_PLUGIN_PATH:$PWD gst-inspect scopes GST_PLUGIN_PATH=$GST_PLUGIN_PATH:$PWD gst-launch audiotestsrc ! audioconvert ! wavescope ! colorspace ! ximagesink GST_PLUGIN_PATH=$GST_PLUGIN_PATH:$PWD gst-launch filesrc location=/home/ensonic/Musik/xotox-hypnocat.mp3 ! decodebin2 ! audioconvert ! wavescope ! colorspace ! ximagesink GST_PLUGIN_PATH=$GST_PLUGIN_PATH:$PWD gst-launch filesrc location=/home/ensonic/Musik/xotox-hypnocat.mp3 ! decodebin2 ! audioconvert ! spectrascope ! colorspace ! ximagesink GST_PLUGIN_PATH=$GST_PLUGIN_PATH:$PWD gst-launch filesrc location=/home/ensonic/Musik/Gridlock/Trace/04\ Uh4.17.mp3 ! decodebin2 ! audioconvert ! spectrascope ! colorspace ! ximagesink GST_PLUGIN_PATH=$GST_PLUGIN_PATH:$PWD gst-launch filesrc location=/home/ensonic/Musik/Gridlock/Trace/04\ Uh4.17.mp3 ! decodebin2 ! audioconvert ! spectrascope shader=fade-and-move-up shade-amount=0x00040302 ! colorspace ! ximagesink GST_PLUGIN_PATH=$GST_PLUGIN_PATH:$PWD gst-launch filesrc location=/home/ensonic/Musik/Gridlock/Trace/04\ Uh4.17.mp3 ! decodebin2 ! tee name=t ! queue ! audioconvert ! synaesthesia ! ximagesink t. ! queue ! synaescope shade-amount=0x00040404 ! colorspace ! ximagesink
