c# - Converting Texture2D into a video -


i've did lot of research, can't find suitable solution works unity3d/c#. i'm using fove-hmd , record/make video of integrated camera. far managed every update take snapshot of camera, can't find way merge snapshots video. know way of converting them? or can point me in right direction, in continue research?

public class fovecamera : singletonbase<fovecamera>{   private bool camavailable;  private webcamtexture fovecamera;  private list<texture2d> snapshots;   void start ()  {      //-------------just checking if webcam available      webcamdevice[] devices = webcamtexture.devices;      if (devices.length == 0)      {          debug.logerror("fovecamera not found.");          camavailable = false;          return;      }       foreach (webcamdevice device in devices)      {          if (device.name.equals("fove eyes"))              fovecamera = new webcamtexture(device.name);//screen.width , screen.height       }       if (fovecamera == null)      {          debug.logerror("fovecamera not found.");          return;      }      //-------------camera found, start video       fovecamera.play();      camavailable = true;  }   void update () {      if (!camavailable)      {          return;      }       //loading snap camera      texture2d snap = new texture2d(fovecamera.width,fovecamera.height);      snap.setpixels(fovecamera.getpixels());      snapshots.add(snap);  } }

the code works far. first part of start-method finding , enabling camera. in update-method i'm taking every update snapshot of video.

after "stop" update-method, convert gathered texture2d object video.

thanks in advance

i see 2 methods here, 1 fast implement, dirty , not platforms, second 1 harder pretty. both rely on ffmpeg.

1) save every frame image file (snap.encodetopng()) , call ffmpeg create video images (ffmpeg create video images) - slow due many disk operations.

2) use ffmpeg via wrapper implemented in aforge , supply videofilewriter class images have. image sequence video stream?

problem here uses system.bitmap, in order convert texture2d bitmap can use: how create bitmap byte array?

so end like:

bitmap bmp; texture2d snap; using (var ms = new memorystream(snap.encodetopng())) {     bmp = new bitmap(ms); } vfwriter.writevideoframe(bmp);

both methods not fastest ones though, if performance issue here might want operate on lower level data directx or opengl textures.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
