Message: <blockquote data-quote="ziphnor" data-source="post: 78693" data-attributes="member: 14215">I got the C# -> Native DirectShow filter communication working. To get a better test platform i made a quick and dirty integration into MediaPortal as follows:I added my AutoCrop filter as a post proc. filter , and added code in the Video player (i dont have any TV recordings on my development machine) to store the interface to the AutoCrop filter when it was added, and then added code to handle a crop action in fullscreen tv and fullscreen video, by showing a 'Cropping Black bars' message and requesting the crop from the AutoCrop filter. Finally i bound this action to the q key(the c key is taken <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> I made a little screen capture video showing it in action(okay, so its not that interesting, but still <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /><a href="http://s16.quicksharing.com/v/7291108/1crop.mp4.html" target="_blank">http://s16.quicksharing.com/v/7291108/1crop.mp4.html</a>The video shows playback of an MPEG-2 video clip from a TV broadcast of 'Interview with the Vampire' in My Videos. ~12 seconds into the video(in a frame with the subtitles shown) i click 'q' on the keyboard and the video is cropped after a small delay of 20 sampled frames. The aspect ratio is set to 'stretch' so since the windows shown is 4:3 people get stretched <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />The white lines shown briefly is the cropping bounds found, and the green lines show what was sampled. The lines are of course only there for testing/debugging <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />Btw, the video is crappy and stuttering only because it was captured using a screen grabbing tool and then mutilated into a decent size MPEG-4 file, there is no stuttering or anything going on in the playback in MP(manual mode will have little to no effect on CPU usage, since its only copying a buffer except when asked to crop).I wouldnt mind some input on how the controls should be in MP btw. I was thinking one key finds new bounds in manual mode, while another key switches between 'off', 'auto' and 'on-request'(ie manual) mode.</blockquote>
