I would like to plug in GPUImage into my pipeline but I am trying to figure out if you can provide the destination pixel buffer that GPUImage writes to?</p> <p>If that is possible (or possible with a small modification) is it possible to render kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange or does GPUImage currently only work for kCVPixelFormatType_32RGBA as pixel format?</p> http://www.sunsetlakesoftware.com/forum/custom-cvpixelbufferref#comments General discussion http://www.sunsetlakesoftware.com/crss/node/620 Sat, 13 Jul 2013 02:39:53 +0000 michel.lonngren 620 at http://www.sunsetlakesoftware.com Record video with other UIview http://www.sunsetlakesoftware.com/forum/record-video-other-uiview <p>You can overlay a view over the video and have UIelements that view and recorder?</p> <p>Thanks you</p> http://www.sunsetlakesoftware.com/forum/record-video-other-uiview#comments General discussion http://www.sunsetlakesoftware.com/crss/node/618 Thu, 03 Jan 2013 08:54:45 +0000 neorichi 618 at http://www.sunsetlakesoftware.com How can I modify the bulge effect to only be a half circle? http://www.sunsetlakesoftware.com/forum/how-can-i-modify-bulge-effect-only-be-half-circle <p>Hello,</p> <p>I would like to use the bulge effect but only half of it. For example I would like to bulge just the right side of the area getting the bulge effect but leave the left side normal without the bulge (as if a line was drawn down the center of the effect and the effect was only applied to one side). How could I modify the code to do this?</p> <p>Thanks!</p> http://www.sunsetlakesoftware.com/forum/how-can-i-modify-bulge-effect-only-be-half-circle#comments General discussion http://www.sunsetlakesoftware.com/crss/node/601 Wed, 28 Nov 2012 14:21:56 +0000 mclejar 601 at http://www.sunsetlakesoftware.com Record video with data overlay information http://www.sunsetlakesoftware.com/forum/record-video-data-overlay-information <p>Good afternoon,<br /> First of all I thank you for your fabulous framework.<br /> Need your help and I need a working example for ios6 where you can record video with data being captured while recording.<br /> Eg record the acceleration data captured while recording the video, it would be possible?</p> <p>I sincerely hope that you can help me on this issue and I'm doing a project for my project for my thesis and I need a working example.</p> <p>Thanks and kind regards.</p> http://www.sunsetlakesoftware.com/forum/record-video-data-overlay-information#comments General discussion http://www.sunsetlakesoftware.com/crss/node/595 Mon, 26 Nov 2012 08:56:07 +0000 neorichi 595 at http://www.sunsetlakesoftware.com Best Way to trigger movie from tracked color? http://www.sunsetlakesoftware.com/forum/best-way-trigger-movie-tracked-color <p>I'm trying to figure out what the "best" way to trigger a movie file to play when a centroid object (e.g.., like in the color tracking example), is on a certain spot x/y.</p> <p>It seems as though, if two images are being composited with a blend shader, that when a movie "runs" out, that the image output freezes. There also doesn't seem to be an explicit "play" method in gpuimagemovie.</p> <p><a href="http://www.sunsetlakesoftware.com/forum/best-way-trigger-movie-tracked-color" target="_blank">read more</a></p> http://www.sunsetlakesoftware.com/forum/best-way-trigger-movie-tracked-color#comments General discussion http://www.sunsetlakesoftware.com/crss/node/594 Sat, 24 Nov 2012 21:02:34 +0000 gtoledo3@gmail.com 594 at http://www.sunsetlakesoftware.com GPUImageMovieWriter and avfiletypempeg4 filetype http://www.sunsetlakesoftware.com/forum/gpuimagewriter-and-avfiletypempeg4-filetype <p>HI,</p> <p>First of all I would like congratulate you Brad for the amazing work.</p> <p>I'm trying to apply a rotation to a given video file and obtain an mpeg4 (AVFileTypeMPEG4) file as output.</p> <p>When doing this I obtain the following message :</p> <p>*** -[AVAssetWriterInput appendSampleBuffer:] Input buffer must be in an uncompressed format when outputSettings is not nil</p> <p>This problem occurs when using the following init method of GPUImageMovieWriter with filetype set to AVFileTypeMPEG4 :</p> <p><a href="http://www.sunsetlakesoftware.com/forum/gpuimagewriter-and-avfiletypempeg4-filetype" target="_blank">read more</a></p> http://www.sunsetlakesoftware.com/forum/gpuimagewriter-and-avfiletypempeg4-filetype#comments General discussion http://www.sunsetlakesoftware.com/crss/node/593 Wed, 21 Nov 2012 09:53:29 +0000 DeepThought 593 at http://www.sunsetlakesoftware.com Encoding movies that are supported for android http://www.sunsetlakesoftware.com/forum/encoding-movies-are-supported-android <p>Which settings and parameters do I need to define to make encoded movies suitable for playing from stream on android devices?</p> http://www.sunsetlakesoftware.com/forum/encoding-movies-are-supported-android#comments General discussion http://www.sunsetlakesoftware.com/crss/node/589 Sun, 11 Nov 2012 20:45:24 +0000 nikita 589 at http://www.sunsetlakesoftware.com Concurrent programming http://www.sunsetlakesoftware.com/forum/concurrent-programming <p>Hi guys (Brad :)), I have been trying to generate a filtered image on a different thread using the iOS 6 way (NSOperationQueue), I am getting always at some point the error: "Error at CVOpenGLESTextureCacheCreateTextureFromImage -6683".<br /> Is this because GPUImage has already its own thread management (see runSynchronouslyOnVideoProcessingQueue)?</p> <p>Is there a way to apply filters to images on a different thread?</p> <p>Thanks!</p> http://www.sunsetlakesoftware.com/forum/concurrent-programming#comments General discussion http://www.sunsetlakesoftware.com/crss/node/588 Wed, 31 Oct 2012 20:44:06 +0000 nuthinking 588 at http://www.sunsetlakesoftware.com Imagefilter like sketch, emboss and RGB... http://www.sunsetlakesoftware.com/forum/imagefilter-sketch-emboss-and-rgb <p>Hi Brad,</p> <p>I realy love your GPUImage-Framework. I need some help with some Filters like sketch, RGB, Emboss...<br /> If I try to manipulate an Image within these kind of filters, the alphachannel is got to be lost. My Images always having a transparent pixelzone. What can I do to keep it ? Can you implement a feature like this or do you have a tricky Idea for me for doing this by myself ? This would be realy great.</p> <p>Best Regards<br /> Hans</p> http://www.sunsetlakesoftware.com/forum/imagefilter-sketch-emboss-and-rgb#comments General discussion http://www.sunsetlakesoftware.com/crss/node/566 Sat, 20 Oct 2012 10:49:04 +0000 hkerman 566 at http://www.sunsetlakesoftware.com GPUImageKuwaharaFilter blocking the main thread? http://www.sunsetlakesoftware.com/forum/gpuimagekuwaharafilter-blocking-main-thread <p>Hi there,</p> <p>I have a question about the GPUImageKuwaharaFilter filter.<br /> The documentation says that it is "extremely computationally expensive [...] it can take seconds to render a frame".<br /> I'm fine with this, so long as I can offload that heavy computation to a background thread and keep the UI responsive as the filter processes its inputs.</p> <p><a href="http://www.sunsetlakesoftware.com/forum/gpuimagekuwaharafilter-blocking-main-thread" target="_blank">read more</a></p> http://www.sunsetlakesoftware.com/forum/gpuimagekuwaharafilter-blocking-main-thread#comments General discussion http://www.sunsetlakesoftware.com/crss/node/559 Wed, 10 Oct 2012 20:04:34 +0000 mabene 559 at http://www.sunsetlakesoftware.com
