Muxing camera preview h264 encoded elementary stream with MediaMuxer

由 若如初见. 提交于 2019-11-30 04:56:23
问题 I am working on an implementation of one of the Android Test Cases regarding previewTexture recording with the new MediaCodec and MediaMuxer API's of Android 4.3. I've managed to record the preview stream with a framerate of about 30fps by setting the recordingHint to the camera paremeters. However, I ran into a delay/lag problem and don't really know how to fix that. When recording the camera preview with quite standard quality settings (1280x720, bitrate of ~8.000.000) the preview and the

How to handle autorotation in AVCaptureVideoPreviewLayer?

由 牧云@^-^@ 提交于 2019-11-30 04:01:13
My application supports all orientations except PortraitUpsideDown. In my view hierarchy I have an AVCaptureVideoPreviewLayer as a sublayer in the top view which is UIImageView. Then below it in view hierarchy are several overlay views showing controls. Overlay views are working properly with orientation changes, but I don't how to be with this AVCaptureVideoPreviewLayer. I want it to behave like in Camera app, so that previewLayer stays still and controls are smoothly reorganized. Right now since the main view is rotated on orientation change, my preview layer is also rotated, which means

由 元气小坏坏 提交于 2019-11-29 20:36:42
I wonder, if there is an Eclipse plugin for code birdview (preview, visualization, minimap, however it may be called)? I mean, when you see your code in a small preview window and may scroll using this window. Wait, I'll show you... Like this. (See the column, where the white rectangle is). Caleb I saw this question again today, and found someone working on such a plugin on github. I have no idea how far progressed this project is, but it may be worth checking out: https://github.com/apauzies/eclipse-minimap-view Hope this helps! Here is "Overview" plugin from a deleted by a mod answer that

How do I preload images into dropzone.js

由 末鹿安然 提交于 2019-11-29 20:26:59
I have a dropzone.js instance on a web page with the following options: autoProcessQueue:false uploadMultiple:true parallelUploads:20 maxFiles:20 It is programmatically instantiated, as it is part of a larger form. I have it rigged up to process the queue when the form is submitted. The goal is for my users to be able to use the dropzone to manage images for an item, so when I load my 'edit/update' view for an item, I'd like to preload the dropzone with the images that had previously been uploaded for that item. Is there a good way to implement this so that the already-there items don't get re

Directshow Preview Only and Capture & Preview with a single Graph

由 三世轮回 提交于 2019-11-29 17:19:38
I have a Directshow application that needs to preview a webcam video, and when user clicks 'Record' it needs to start capturing the video to a file. To that end I created a single Capture Graph, with PREVIEW pin connected to a RENDER filter and CAPTURE pin connected to a AVI_MUX filter that saves to a file. It looks something like this: /[PREVIEW PIN]-->[VIDEO_RENDERER]--->[SCREEN] [VIDEO CAPTURE FILTER] / \ \[CAPTURE PIN]--->[AVI_MUX]--->[FILE WRITER] When I call Run() on the graph the video shows on screen and gets saved to the file correctly. My question is, how can I only run the PREVIEW

ASP.NET MVC 2 - HTML.EditorFor() and Custom EditorTemplates

由 不羁岁月 提交于 2019-11-29 13:35:00
问题 With MVC 2's addition of the HtmlHelper EditorFor() it is not possible to create strongly typed Display and Editor templates for a given Model object and after fiddling with it I am a bit stumped as to how to pass additional Model data to the editor without losing the strong-typing of the editor control. Classic Example: Product has Category. ProductEditor has a DropDownList for Category containing the names of all Categories. The ProductEditor is strongly typed to Product and we need to pass

Best way to show image previews before upload in rails & carrierwave

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-11-29 12:15:49
问题 I've been using rails for past few days and wanted to know what is best way to show image previews before upload in rails & carrierwave. I came across a few options like using plupload or jquery file upload or using uploadify. 回答1: If you only need image preview in a form before upload, you (as me) will see that JQuery Upload plugin is just too much complex and not so easy to run properly (I was able to see the preview, but then I couldn't upload the picture). http://saravani.wordpress.com
